The sample of this study is 98 students taken based on purposive sampling techniques. This study uses descriptive statistics to analyze the data generated. From the results of the analysis that has been done, it was found that there is a problem solving indicator by students in mathematics which is a indicated by the indicators of planning a solution which has a good category of a 56.1% (55 of 98) students, the indicator of problem solving has a good category of a 56.1% (55 out of 98) students, indicators of a problem solving planning had a good category of a 54.1% (53 of 98) students, and an indicator of understanding a problem had a good category of a 60.2% (59 of 98) students.
Despite its central place in the mathematics curriculum the notion of mathematical proof has failed to permeate the curriculum at all scholastic levels. While the concept of mathematical proof can serve as a vehicle for inculcating mathematical thinking, studies have revealed that students experience serious difficulties with proving that include (a) not knowing how to begin the proving process, (b) the proclivity to use empirical verifications for tasks that call for axiomatic methods of proving, and (c) resorting to rote memorization of uncoordinated fragments of proof facts. While several studies have been conducted with the aim of addressing students’ fragile grasp of mathematical proof the majority of such studies have been based on activities that involve students reflecting and expressing their level of convincement in arguments supplied by the researchers, thereby compromising the voice of the informants. Further, research focus has been on the front instead of the back of mathematics. Hence, there is a dearth in research studies into students’ thinking processes around mathematical proof that are grounded in students’ own proof attempts. Therefore current investigations should aim at identifying critical elements of students’ knowledge of the notion of proof that are informed by students’ actual individual proof construction attempts.
In many schools, the vision mission just "exists" and not become a guideline especially implementation of learning. The school just execute school routine without knowing the meaning of implementation.

How is the capacity of school management in developing the vision and mission? The goal of the research is to describe and analyze the capacity of school management in developing the vision and mission. This study used a qualitative approach with case studies. Data collection methods used are interviews, observation, and study of the document/artifact. The validity of the data is done with credibility, transferability, dependability, and confirmability. The results show that schools which establish vision and mission based on noble values of the founders have a strong base for the development.
A learning program not only aims to make students understand and master what and how things happen, but also provide an understanding of why it happened. Thus, a lesson that emphasizes problem-solving becomes very important to teach. One form of learning that emphasizes the problem solving is to apply systematic approach to problem solving. This is a guide to perform an action that serves to assist a person in solving a problem. Problem solving steps based on systematic approach to problem solving consists of four stages, namely problem analysis, problem solving process planning, calculation operations, and checking answers and interpretation of results. This study is a classroom action research that aims to see the inceasing of student learning outcomes after applied systematic approach to problem solving. The subject of this research is 25 students of class VIIIA MTs Salafiyah Syafi'iyah Tebuireng Jombang. Instruments in this study is a matter of student learning outcomes on the material wake up space. This research was conducted in two cycles because in the second cycle has reached the indicator of success that students achieve the minimal clarity of at least 75%. The results showed that student learning outcomes in the first cycle reached 36% classical completeness, and in the second cycle of classical completeness of 84%. This shows that the application of systematic approach to problem solving can increase student learning outcomes.

In this research, 30 minutes was given to the participants to solve 20 questions, which tested teachers' knowledge related to verbal counting sequence, counting, the ordinal number of words, addition/subtraction, divisions of sets, written number symbols, and words. Besides, the interview was conducted to get more indepth information from the participants. The quantitative descriptive analysis was used to identify the frequency, percentage, mean value, and standard deviation. The result of the research showed that ECE teachers had limited knowledge of children's mathematical development. It was revealed by the result of the mean value of the teachers’ responses, which were only 33% correct answers and 16% no idea answers. This result can become input for the stakeholders to hold a professional development program which aims to increase the quality of ECE teachers related to mathematical development activity.
Metacognitive Strategies: Instructional Approaches in Teaching and Learning o...IJAEMSJORNAL
The purpose of the study is to determine the effectiveness of the metacognitive strategies as instructional approaches in teaching and learning of Basic Calculus. A number of 48 students consisting of 24 boys and 24 girls were purposively sampled in this study. Pretest-posttest quasi experimental research design was used which applied t-test and descriptive statistics. Both groups were subject to two instruments that were comprised of problem-solving test (pretest and posttest) and observation guide. Experimental group was taught Basic Calculus using metacognitive strategies while the control group was taught Basic Calculus using traditional teaching strategies. Both groups were subject to a pretest. Class observation was done while the two teaching strategies were applied. In the end, the posttest was administered to both groups to identify the effectiveness of the two teaching strategies. The data gathered were treated using paired sample t-test and independent sample t-test. The results of the study showed that the experimental group had significantly higher posttest scores as compared to control group which proved that metacognitive teaching strategies were more effective in improving the performance and problem-solving skills of the students than the traditional teaching strategies. It was also observed that students who taught using metacognitive strategies helped the students to be extremely engaged in Basic Calculus lessons cognitively, behaviorally, and affectively. The study reveals that the significant increase of the students’ learning engagement in Basic Calculus lessons led the students to a corresponding increase in their posttest scores.

A textbook is the main source of learning in many universities, yet there are only a few studies which specifically evaluate accounting textbook. This research aimed to evaluate the accounting textbooks used in some Indonesian universities and is expected to provide recommendations of accounting textbooks which are potential to develop students’ critical thinking ability. This study was a content analysis. The analysis was based on the Bloom’s taxonomy as well as the indicators of contextual representation intensity level. The results demonstrated that critical thinking receives little attention, either in the components of learning objectives, practice exercises or the materials/main content. Accounting textbook written by foreign authors seems to have higher quality than those written by local authors. It is suggested that the accounting academicians in Indonesia collaborate with accounting practitioners to develop a better quality textbook by adapting the superiorities of textbooks written by foreign authors and eliminating the weakness.
The purpose of this research is to analyze the improvement of students' mathematical literacy ability through the use of mathematics teaching materials with metacognitive approach guidance.

Analysis Of Students Ability In Solving Relation And Functions Problems Base...Vicki Cristol
The document analyzes students' ability to solve relation and function problems based on learning indicators. It finds that students' overall ability is low. Specifically:
- Ability to define relations and functions is low. Students forget definitions.
- Determining examples and non-examples of functions is medium. Most but not all students can distinguish them.
- Determining domain, codomain, and range is medium. Students sometimes confuse range and codomain.
- Drawing arrow and Cartesian diagrams is medium. Students can usually draw them but omit descriptions.
The study indicates students have forgotten basic concepts and recommends teachers focus more on understanding than memorization to improve problem-solving abilities.

extracted from the data-logs of the intelligent tutor, ALEKS. This data was triangulated with the data
collected from surveys. Two-step clustering, correlation and regression analysis, Chi-square analysis and
paired sample t-tests were applied to address the research questions.
Findings: The data-logs of ALEKS include information about number of topics practiced and number of
topics mastered by each student. Prior knowledge and derived attribute, which is the ratio of number of
topics mastered to number of topics practiced(denoted by the variable m top in this paper) are found to be
predictors of final marks in the foundation mathematics course with
= 42%.
Students were asked to report their preferred way of selecting topics as either sequential or random.
Results of paired sample t-test demonstrated that the students who selected topics in a sequential manner
were able to retain their mastery of learning after the summative assessment whereas the students who
chose topics randomly were not able to retain their mastery of learning.
Originality and value: This research has established three indicators of academic success in the course of
foundation mathematics which is delivered using the intelligent tutor ALEKS. Instructors can monitor
students’ progress and detect students at-risk who are not able to attain desired pace of learning and guide
them to choose the correct sequence of topics.

This research was conducted due to the importance value of mathematics for early childhood and the fact some researches showed the early childhood education (ECE) teachers' low level of basic mathematical knowledge, especially the one related to childhood developmental stages. The participants of this research were 35 ECE teachers from one of the cities in West Java province with teaching experience approximately ten years. In this research, 30 minutes was given to the participants to solve 20 questions, which tested teachers' knowledge related to verbal counting sequence, counting, the ordinal number of words, addition/subtraction, divisions of sets, written number symbols, and words. Besides, the interview was conducted to get more indepth information from the participants. The quantitative descriptive analysis was used to identify the frequency, percentage, mean value, and standard deviation. The result of the research showed that ECE teachers had limited knowledge of children's mathematical development. It was revealed by the result of the mean value of the teachers’ responses, which were only 33% correct answers and 16% no idea answers. This result can become input for the stakeholders to hold a professional development program which aims to increase the quality of ECE teachers related to mathematical development activity.
Metacognitive Strategies: Instructional Approaches in Teaching and Learning o...IJAEMSJORNAL
The purpose of the study is to determine the effectiveness of the metacognitive strategies as instructional approaches in teaching and learning of Basic Calculus. A number of 48 students consisting of 24 boys and 24 girls were purposively sampled in this study. Pretest-posttest quasi experimental research design was used which applied t-test and descriptive statistics. Both groups were subject to two instruments that were comprised of problem-solving test (pretest and posttest) and observation guide. Experimental group was taught Basic Calculus using metacognitive strategies while the control group was taught Basic Calculus using traditional teaching strategies. Both groups were subject to a pretest. Class observation was done while the two teaching strategies were applied. In the end, the posttest was administered to both groups to identify the effectiveness of the two teaching strategies. The data gathered were treated using paired sample t-test and independent sample t-test. The results of the study showed that the experimental group had significantly higher posttest scores as compared to control group which proved that metacognitive teaching strategies were more effective in improving the performance and problem-solving skills of the students than the traditional teaching strategies. It was also observed that students who taught using metacognitive strategies helped the students to be extremely engaged in Basic Calculus lessons cognitively, behaviorally, and affectively. The study reveals that the significant increase of the students’ learning engagement in Basic Calculus lessons led the students to a corresponding increase in their posttest scores.

Cognitive dimensions development is one of the objective of education. This research aimed to identify the structure, evaluate the focus, analyze the conformity toward the referred adoption standard, and evaluate the emphasis of thinking skill order of cognitive processes in the e-textbook for 4th grade students. Evaluation was carried out for the curriculum 2013 e-textbooks published in 2014, including theme 2, 3 and 4. Identification of cognitive process dimensions was carried out using revised Bloom’s taxonomy, while the conformity was anayzed using Alzu’bi’s preference. Statistical analysis was carried out with chi-square test. The result showed that the structure of cognitive dimensions in three examined e-textbooks were not consistent one another. Theme 2 emphasized on the high order thinking skill focused on the creating dimension. Theme 3 emphasized on the low order thinking skill focused on the understanding dimension. While theme 3 facilitated both thinking skill orders with a little tendency to the evaluating dimension. There was no conformity of the cognitive dimensions structure of the three themes toward the referred adoption standard. Statistical analysis showed that there was significant difference on the structure of cognitive dimensions between themes, and between each themes and the referred adoption standard.
Anxiety becomes one of the psychological symptoms that can appear in every student while solving mathematics problems. Anxiety cannot be denied to be one factor that affects students’ learning outcomes and interest in mathematics. Therefore, teachers should concern on this matter in order to decide the appropriate learning strategy. However, there is no instrument to measure the level of students’ anxiety towards mathematics, especially for junior high school students. For that reason, this research aims to: 1) design the construct of math anxiety scale instrument, 2) find out the validity of the instrument. This research used Research and Development method to develop and validate the product which is in the form of a questionnaire. The analysis techniques used V Aiken for content validity, EFA for construct validity, and Cronbach’s Alpha for the reliability. The results of this research showed that the instrument was valid and reliable because it met the criteria for validity and reliability. In conclusion, the instrument is valid to measure the junior high school students’ math anxiety level.

This study aims to investigate whether student anxiety about the subject of mathematics has any effect on the achievement of middle-school students in Amman, Jordan. It also aims to investigate whether student gender plays a role. The study sample consists of 180 seventh grade students enrolled in Amman public schools during the 2018/2019 academic year. These are distributed into three levels of anxiety as displayed by the students: low, middle, and high. Then, math anxiety measurements are collected, the validity and reliability for which are verified. The results reveal that there are statistically-significant differences in achievement between the middle level of math anxiety and the two other extremes. It is found that middle anxiety level have a positive effect on achievement, whereas for low and high math anxiety levels, no differences in achievement are perceived. In addition, no statistically significant differences (α≤0.01) were found between males and females with regards to math anxiety; and there is no interaction between the level of math anxiety and gender in achievement.
1. Assessment for learning is different from assessment of learning in that it is used to help students learn better rather than evaluate learning. It helps students and teachers see learning goals, a student's progress, and next steps.
2. Research shows that assessment for learning is one of the most powerful ways to improve learning, especially for students who find learning challenging. It helps students learn better now and achieve more throughout their education.
3. Classroom assessment techniques developed by teachers help make the learning process more methodical and systematic by providing feedback to improve teaching methods.

A textbook is the main source of learning in many universities, yet there are only a few studies which specifically evaluate accounting textbook. This research aimed to evaluate the accounting textbooks used in some Indonesian universities and is expected to provide recommendations of accounting textbooks which are potential to develop students’ critical thinking ability. This study was a content analysis. The analysis was based on the Bloom’s taxonomy as well as the indicators of contextual representation intensity level. The results demonstrated that critical thinking receives little attention, either in the components of learning objectives, practice exercises or the materials/main content. Accounting textbook written by foreign authors seems to have higher quality than those written by local authors. It is suggested that the accounting academicians in Indonesia collaborate with accounting practitioners to develop a better quality textbook by adapting the superiorities of textbooks written by foreign authors and eliminating the weakness.
The purpose of this research is to analyze the improvement of students' mathematical literacy ability through the use of mathematics teaching materials with metacognitive approach guidance. This research will be held in the city of Kendari to the subject of this research target is students who are at grade 5 Land in Junior High VIIID Kendari years lessons 2017/2018 with many limited scale trial class is only required as much as 1 class. To know the significance of the increase in the literacy abilities of students using paired t-test. Data processing using the SPSS program with criteria if α=0,05 then there is an increased of student's mathematical literacy ability. The results of the analysis on the stages of the evaluation shows the learning materials with metacognitive approach guidance can provide better against an increase in student learning. The ability of the early mathematical literacy against students is very less because of learning during this time students have not been directed with the ability of mathematical literacy. After the students get learning by using learning materials through metacognitive approach guidance, the ability of mathematical literacy students’ level 3 and level 4 underwent significant improvement.

Analysis Of Students Ability In Solving Relation And Functions Problems Base...Vicki Cristol
The document analyzes students' ability to solve relation and function problems based on learning indicators. It finds that students' overall ability is low. Specifically:
- Ability to define relations and functions is low. Students forget definitions.
- Determining examples and non-examples of functions is medium. Most but not all students can distinguish them.
- Determining domain, codomain, and range is medium. Students sometimes confuse range and codomain.
- Drawing arrow and Cartesian diagrams is medium. Students can usually draw them but omit descriptions.
The study indicates students have forgotten basic concepts and recommends teachers focus more on understanding than memorization to improve problem-solving abilities.

This research aimed to determine the effectiveness of the issue, discussion,
establishment, and application (IDEA) learning model in embedding
mathematical concepts understanding. It is a quantitative study with a quasiexperimental
approach. This research was conducted at Malang Islamic
University with students majoring Mathematics education study program
and in their first academic year as the subjects. Subjects were divided into
two group, experimental and control and measured their result using posttest
only control group design. There are six instruments consisting six items
used to measure mathematical concepts understanding. The results
confirmed that H0 is rejected, while Ha is accepted proved by t count
(3.132)>ttable (1.674). It means there is a significant difference between the
of both groups (experimental and control). In addition, the results indicated
that the IDEA learning models is effective to assist students in understanding
mathematical concepts showed by the higher score of experimental groups
than control group. Three factors are involved in order to implement the
IDEA learning model effectively; namely: individual problem-solving
opportunities, active student involvement, and guidance and assistance (from
lecturer) on the IDEA learning model. This research is only limited to
preservice teacher, further research is required in order to implement this
model for mathematics learning at junior and senior high schools’ level.
An Investigation Of Secondary Teachers Understanding And Belief On Mathemati...Tye Rausch
1) The document discusses secondary teachers' understanding and beliefs regarding mathematical problem solving in Indonesia. It investigates how teachers understand problem solving concepts like problems, strategies, and instructional practices, as well as their self-reported difficulties.
2) The study found that teachers have a good understanding of pedagogical problem solving knowledge but a weaker understanding of problem solving content knowledge such as strategies. Teachers reported that their main difficulties are determining precise mathematical models and choosing suitable real-world contexts for problems.
3) The study also examined teachers' beliefs about mathematics and learning, finding they tend to view mathematics as static but believe problem solving should be taught dynamically to engage students.
Problem-based learning is generally done with face-to-face interaction. This learning process, however, has not provided a lot of time for learners to find limitless and timeless information and learning resources. It still depends on the teacher as a source of information. Students are very dependent on the presence of lecturers during face-to-face interaction. This research aims to develop a Problem-based Blended Learning (PB2L) model to support student to improve their creative thinking skills. The method used in this research was R&D with ASSURE development model. Product validation was done through an expert’s assessment by using the expert’s validation sheet. The practicality of the product is tested with limited trials with college lecturers and some students with questionnaires and interviews. Product effectiveness was seen by implementing limited development testing to a particular class with a one group pretest-posttest design and the result was analyzed by using a Paired-Samples T-Test. The result of this research is a Problem-based Blended Learning (PB2L) valid, practical and effectively improves students' creative thinking abilities. The effectiveness of the learning model was also proven on the basis of Paired-Samples T-Test of students’ pretest and posttest with sig. (2-tailed) 0.000. This learning gives students the opportunity to think systematically by beginning by criticizing the interesting contextual problems and ending with meaningful reflection with adequate learning resources both in face-to-face and online interaction.
The affective aspects must be owned by students in a lesson, where the
affective aspects will have a relationship with the cognitive aspects of a
student, therefore this study aimed to determine whether there is a
relationship between students 'mathematical dispositions and students'
mathematics learning outcomes. Using a mixed method and a sequential
explanatory plan, the research was undertaken by first collecting quantitative
data and then continuing to collect qualitative data. Where, the sample count
in this study was 413 students from junior secondary schools 18 in Jambi
City, Indonesia who used a total sampling technique. Data were then
analyzed with the help of SPSS 21 application to find descriptive statistics in
the form of mean, min, max, and category as well as inferential statistics
using Pearson Product Moment. The results obtained in this study dominate
both the mathematical disposition of pupils and the learning outcomes of
pupils in mathematics. This was reinforced by the existence of a relationship
between mathematical disposition and student learning outcomes in
mathematics which is indicated by the obtained sig <0.05. This means that
the mathematical disposition of students which includes the affective aspect
of students has a relationship with the cognitive aspect, by having a good
affective aspect, the cognitive aspects of the student are also good.
The previous research result showed that the learning model based on the investigation could increase the students’ critical thinking skills. The aim of this research was to measure the effectiveness of the using of problem-based learning model to increase the students’ critical thinking skills. The research design was quasi-experiment by using post-test only design. The population of this research was the eleventh grade students of science which contained 124 students of SMAN 6 and SMAN 7 Kupang that were chosen randomly. The treatment that was given in this research was problem-based learning model for the experiment class and conventional model for the control class whereas the given materials were the reaction rate. The instrument that was used in this research previously validated by two experts of theory and material. The result of this research showed that the students who studied in experiment class had different critical thinking skills better that the students who studied using conventional model.
Problem-based learning (PBL) has been widely applied as an alternative to improve learning outcomes, but it is still little studied in the context of the probability theory course. This study described how implementing the PBL model improves students’ problem-solving and critical thinking skills in probability theory course and evaluates its quality. This design research involved 58 undergraduate students and two probability theory course lecturers from two universities in Indonesia as participants. Data collection used observation to describe PBL implementation, then questionnaire and pretest-posttest to evaluate the quality of the model. This study produced a PBL model for the probability theory course which is implemented through five steps: i) Orienting students on problems; ii) Organizing students to study; iii) Assisting individual and group investigations; iv) Developing and presenting work or solutions; and v) Analyzing and evaluating problem solving processes. Lecturers and students consider that the implementation of PBL is practical. PBL implementation can also improve students’ problem-solving skills and critical thinking in the probability theory course. Thus, implementing PBL can be used as a solution to optimize learning outcomes in the probability theory course.
Due to the increasing interest in big data especially in the educational field and online education has led to a conflict in terms of performance indicators of the student. In this paper we discuss the methodology of assessing the student performance in terms of the success indicators revealing a number of indicators that is recommended to indicate success of the final academic achievement

This research aims to produce a mathematics module on circle material based on the small group discussion model to improve learning outcomes. The fact is that there are 48% of students who get low mathematics learning outcomes. Another fact is that at the high school level, 62% of students in circle material scored below the minimum completeness criteria. Urgent development research was carried out to produce circular module products. The method in this research is research and development (R&D). The subjects and objects of the research were high schools and there were 32 students. Data collection techniques, material expert instruments, teachers, and student data were also obtained from the results of student pre-tests and post-tests. The data was analyzed by adding up all the assessment scores on the instruments adding up the test results and averaging the individual and classical scores. The results, and assessment of all module components by material experts, mathematics teachers, small group trials, and large group trials were 88.29%, 90.45%, 93.50%, and 92.10% in the very good category. The average score of students' post-test results is 87.50. Conclusion, this circle module can improve student learning outcomes significantly.
This study aims to reveal the profile of open-start problem-solving with ethnomathematics regarding student learning styles. This research is a qualitative research study on 3 out of 31 students of Junior High School of 3 Magetan taken by purposive sampling. The three students carried out four stages: understanding the problem, planning problem-solving strategies, implementing problem-solving strategies, and reviewing again. The results of the research show that students with a visual learning style solve problems by understanding problems through writing known and being asked and drawing illustrations, planning problem-solving strategies by making examples, carrying out solving strategies by working on the calculation process; students with an auditory learning style solve problems by understanding problems through writing known and being asked, planning strategies by making problems and formulating formulas used, implementing solutions by doing calculations and reviewing; students with a kinesthetic learning style solve problems by understanding issues through writing known and being asked, making examples and writing the formulas used, carrying out solving strategies by applying the calculation process and reviewing the results obtained. However, of the three styles, the results of the accepted work were not correct because they did not write down the conclusions and were not thorough enough.

The role of entrepreneurship in addressing the issue of educated unemployment is well acknowledged, while its specific implications for health professions students remain inadequately explored. This study's main objective is to investigate entrepreneurship education's effect on entrepreneurial intention by considering entrepreneurial self-efficacy as a mediator in students majoring in medical laboratory technology. This quantitative research uses an exploratory approach involving 300 respondents determined through simple random sampling techniques and analyzed using partial least square structural equation model (PLS-SEM). The analysis revealed that entrepreneurship education directly impacts self-efficacy and entrepreneurial intention. Furthermore, entrepreneurial self-efficacy was identified to exert a positive mediating effect between these variables. However, the effect size between the relationships of the research variables is low. Nevertheless, higher education offering health majors can optimize entrepreneurship education by implementing practical learning and field experience to increase confidence and intention in entrepreneurial activities.
Recent studies claimed that the absence of a paradigm is a challenge to developing education for sustainable development and soft skills competencies. This integrative study examines stimulating these transferable and transversal competencies through constructivist approaches to teaching from the cognitive, social, radical, and critical perspectives. The study argues that the use of constructivist approaches to teaching can contribute to the achievement of education for sustainable development and soft skills competencies through the delegation of power from teachers/lecturers to students. This, in active and interactive classrooms, empowers students and builds their confidence to develop on the personal, academic, and professional levels. The use of the cognitive constructivist approach assists in developing competencies based on a clear understanding of the cognitive structures of students in a vibrant classroom environment. The use of the social constructivist approach assists in constructing individualized learning environment based on predetermined zones of proximal development in sociocultural contexts. The radical and critical constructivist approaches to teaching, through the rejection of conventional epistemologies, allow students the freedom to creatively address issues related to environmental, economic, and social sustainability. This becomes effective through the fostering of self and social awareness, challenging existing ideas, and provoking innovative thoughts that are necessary to shape a sustainable future.
The research aimed to describe the development of solar electric cars as a prop in energy conversion learning using the analyze, design, develop, implement, and evaluate (ADDIE) model and to ascertain the effectiveness of an electric car as a prop in energy conversion learning. Utilization of prop in the learning process is one way to support the development of knowledge, skills, and basic needs for delivering material, concepts, and physics information. This research is a descriptive study involving media and pedagogical experts and 40 students of the university in Tasikmalaya. Data collection techniques were carried out through the study of literature, expert validation, and student perception questionnaires. Expert validation and student perception were obtained by using a Likert scale. The expert judgment results were processed using the V value equation developed by Aiken. The results showed a value of 1, meeting the minimum validation requirements. The students also had positive responses to a prop. They have new experience learning in energy conversion and have good media to help their comprehension. It has a significant impact on helping students to achieve their learning goals.
The rise and growing prevalence of juvenile delinquency is a matter of concern for many parties. This study aims to establish a research instrument in the form of a questionnaire that can be deployed to assess the learning environment perceived by high school students. This research endeavor constitutes a developmental study, wherein the outcomes are a single survey instrument encompassing six variables, nineteen indicators, and forty questions. The data-collecting process involved the utilization of a Google Form across five schools in five districts, containing a total of 1615 participants. The analysis of expert data was conducted utilizing V. Aiken and field trials employing confirmatory factor analysis (CFA) Second Order. The findings of this study indicate that the diagnostic survey instrument used to assess the learning environment's impact on the mental health of high school students demonstrated validity, as evidenced by loading factor values exceeding the established minimal threshold. The reliability of the instrument remains insufficient. This survey can be utilized to detect adolescent persistent tendencies carried out by students or other school members that interfere with mental health: the emergence and significant raising of juvenile delinquency.
Marinyo is a culture left by the Portuguese around the 15th century in Maluku. The purpose of this study was to find out to what extent students' misconceptions about the concept of sound in the Marinyo case in the Kepuluan Tanimbar Regency. The method used was a qualitative study in ethnography in ten villages in two sub-districts. In addition, they conducted a survey in the form of a diagnostic test in the form of questions related to the Marinyo case on 300 elementary school students. The findings in the field show that students experience relatively high misconceptions. It was because teachers did not accustom students to learn from natural phenomena around them and were given scientific questions to seek, find and provide answers and solutions related to these natural phenomena. The teacher was more pursuing the conditions and problems of physics in textbooks and less exploring contextual matters. Future researchers are suggested to develop physics or science teaching materials based on regional local advantages that are oriented towards understanding concepts, mental models, critical thinking, problem-solving, creativity and innovative thinking so that teachers and students can learn well so that knowledge of science becomes better.
Online learning is a growing trend in education during the corona virus disease (COVID-19) pandemic. The purpose of this study is to ascertain the difficulties that online majors in non-English languages have when attempting to acquire English. The subject of this study involved using the questionnaire method for as many as 412 students and interviewing 15 students with a total of 17 questions. The results of this study indicate that there are several challenges faced by students during online learning; i) less familiarity with online learning as shown by 31% of students agreeing that online learning is a new learning method, ii) psychologically 30% of students choose strongly agree that they have limited opportunities to interact directly and freely with lecturers as well as with students, iii) limited facilities and infrastructure as much as 28% agree that the budget is limited to get quota or internet credit, and iv) limited internet access as many as 35% of students do not have good internet coverage to take online lectures. The findings of this study should be a reference for English lecturers to continue learning to innovate in providing online English learning by considering the existing challenges.
English for young learners (EYL) teachers have practiced some creative activities to maintain their pupils’ learning with natural exposure to the target language amidst the pandemic. One activity practiced by Indonesian and Korean teachers was an international collaboration to perform a virtual drama of each country’s folktale. This phenomenological research aimed at tapping the teachers’ perceptions regarding interculturality and world Englishes (WE) in the virtual dramatic play collaboratively conducted and delving into their commitments in honing interculturality and WE. Two Indonesian and Korean teachers were involved in three sessions of in-depth interviews using pre-prepared interview questions. The trustworthiness of the data was achieved by the group discussions allowing the participants to comment on and revise the transcribed data, as well as triangulation by two international collaborators. Thematic analysis was performed to identify emerging themes and to provide novel insights into EYL teachers' encounters with interculturality and WE. The Indonesian and Korean teachers admitted the compatibility between language and culture, the urgency of introducing varieties of English, and the merits of conducting international collaboration to promote interculturality and WE. The teachers are committed to integrate interculturality and WE in their instructions despite some differences in the stipulated curricula.
The fear of failure stops students from thinking logically and processing information in mathematics. Creating an appropriate classroom climate based on every student's ability is crucial to overcoming the prejudices associated with mathematics. In this regard, this study aims to create the best classroom climate approach that will increase interest in mathematics and ensure academic success. For this purpose, mathematicians' views on the classroom climate approach and how they create them were discussed by using qualitative techniques. It was considered that teachers participating in this research are working in 9th grade in state high schools affiliated with the Turkish Republic of North Cyprus Ministry of Education, accepting students through examination. The researchers collected teacher views through a semistructured interview form and analyzed them using context analysis. The findings showed that teachers were in a hurry to teach and generally paid attention to creating a comfortable classroom climate in which students could express their thoughts and opinions. This situation also revealed a lack of adequate classroom climate approach skills among teachers. Therefore, the classroom climate approaches discussed in this study are expected to make a significant contribution to this field by offering solutions to teachers in creating a supportive classroom climate.
The article is devoted to the study of the issue of training future police officers to use unmanned aerial vehicles (UAVs) in their professional activities. Based on the results of the theoretical analysis of scientific and applied works, modern trends in the development of drones in the activities of law enforcement agencies were identified, and the problem of their implementation in practical activities was outlined. An online survey was conducted in order to study the opinion of scientific, scientific and pedagogical workers and graduates of higher education institutions with specific learning conditions that train police officers about the need to train future police officers in the control of UAVs. The need to introduce into the system of primary professional training the training of service skills using drones is substantiated. On the basis of the study of the content of the training program for unmanned aircraft systems of the first class according to the basic qualification level of the first level, it is proposed to introduce the general professional educational unit “formation of skills and skills of controlling an UAV” into the training program of the primary professional training of police officers in the specified specialty.

This study aimed to explore the application of context-responsive pedagogy in ELT within the unique context of Islamic boarding schools in Indonesia. This qualitative study employed semistructured interviews and classroom observation as data generation methods to gain insights into the experiences and perspectives of English language teachers regarding the implementation of context-responsive pedagogy in English language instruction. The findings revealed the importance of understanding learner needs, incorporating authentic materials, promoting cultural sensitivity, and effective use of technology in ELT practices in Islamic boarding school contexts. This study delves into how English language teachers navigated and negotiated their practices with the socio-cultural and religious values entrenched in this institution. It also highlighted the challenges English language teachers in this school context faced in the implementation of context-responsive pedagogy. Eventually, this research provides valuable insights for ELT practitioners, policymakers, and researchers interested in incorporating context-specific pedagogy to optimize ELT in Islamic boarding schools and similar educational contexts.
This study aimed to develop and evaluate a training curriculum intended to enhance the quality of life for the elderly. As Thailand witnesses a demographic shift with increasing numbers of older adults, driven by declining birth rates and extended life expectancies, the importance of ensuring quality elderly care becomes paramount. The devised curriculum encompasses eight principal elements focusing on the elderly, defined as those aged 60 and above, addressing their physical and mental changes, well-being, health, and overall satisfaction. The content is holistic, integrating components of music, art, health care, and exercise. Delivered over a two-day period, the curriculum employs a structured approach featuring lectures, discussions, and knowledge exchanges, supported by a range of media and materials. Initial assessments revealed a moderate quality of life among the elderly, but post-training evaluations indicated enhanced knowledge, understanding, and positive attitudes towards the activities, pointing to an overall high level of effectiveness of the curriculum.
The study of the role of the pedagogy of partnership (PoP) in building the professional competence of future primary school teachers is relevant in the context of modern educational and pedagogical transformations, which require the preparation of teachers for new challenges and creating a favourable learning environment. Therefore, the aim of our study was to check the effect of observing the pedagogical partnership principles in the educational process on the development of the communicative competence of future primary school teachers. The study employed the following psychodiagnostic methods: the Thomas-Kilmann conflict mode instrument (TKI), Myers-Briggs type indicator (MBTI), Snyder’s self-control in communication. The implementation of the PoP programme in higher education institutions (HEIs) has a positive effect on the development of the communicative competence of future teachers, in particular, on developing the ability for self-control and increasing the scope of psychological knowledge. The study revealed some important correlations. Our results indicate that cooperation and the ability to make compromises are directly related to the communicative abilities of future teachers. Further research can be focused on studying the impact of pedagogical partnership on other aspects of future teacher training, such as methodical mastery, motivation for learning and development.
This study examined the relationship between students’ academic performance, teachers’ commitment, and leadership behavior of school administrators. Teachers’ commitment was measured in two areas– commitment to job and commitment to organization and the leadership behavior of school administrators were evaluated in terms of consideration and initiating structure. Eighty-one teachers, 11 school heads, and 470 students served as respondents. The descriptive survey research technique, correlation analysis, and the following statistical methods were used: frequency, mean, standard deviation, and correlation coefficient. The study revealed that the initiating structure and consideration dimensions of leadership behavior affect teachers’ commitment to job (CTJ) and teacher’s commitment to organization (CTO). The correlation between CTJ and CTO and leadership behavior-initiating structure is positive and with leadership behavior-consideration negative. CTJ and CTO is correlated with the students’ academic performance in math, but not in Science and English. The correlation is negative. Students’ academic performance in all subject areas is negatively correlated with leadership behavior-initiating structure and has no significant relationship with leadership behavior-consideration. The leadership behavior-initiating structure is positively correlated with teachers’ commitment to both job and organization but has negative correlation with students’ academic performance in math, science, and English.
This study aims to describe preservice mathematics teacher knowledge of higher order thinking skills in terms of definition, Bloom's taxonomy level, curriculum, learning, and evaluation. This research is quantitative research with a survey method. and sample consisted of 248 preservice mathematics teachers in semesters VI - VIII of the Department of Mathematics Education, Nusa Cendana University, Timor University, and Wira Wacana Sumba University. The instrument used was a questionnaire about high order thinking skill (HOTS) which consisted of 105 statements. Data analysis used Likert's summeted rating, one sample test, Mann Whitney, Kruskall-Wallis tests, multiple linear regression test, and multivariate analyisis of variance (MANOVA) test. The results showed that the knowledge level of preservice mathematics teacher was in the good category. Based on gender differences, there was no significant difference in the average knowledge of preservice mathematics teacher about HOTS, there was a significant difference in the average knowledge of preservice mathematics teacher about HOTS which is significant based on differences in academic ability and gender differences do not significantly affect knowledge about HOTS levels in Bloom's taxonomy, curriculum, and pedagogy while academic knowledge has a significant effect on HOTS knowledge of preservice teachers in almost all aspects except for pedagogy.
Formative assessment is an evaluative practice developed in the classroom for the improvement of learning using evidence on student progression. The objective of this research is to compare sample groups from multigrade and single-grade classrooms on the theme of formative assessment based on the students' opinion of the teacher's performance. The method used was a comparative quantitative method. The sample type is a probability sample of 683 students from 5th to 8th grade from urban and rural schools in the commune of Longaví, located in the Maule Region of Chile. A validated Likert scale questionnaire with a high level of reliability (α = 0.93) was used. The results of the research showed that, in the six dimensions, the best teacher performance concerning formative assessment is found in multi-grade schools and not in single-grade schools. This can be explained on the basis of several reasons, among them the level of adaptability that teachers have in this type of classroom, the heterogeneous characteristics of the classroom (different ages and learning goals) and the need for teachers to monitor the learning progression of students with different classroom characteristics.
Financial literacy, as a fundamental skill in the 21st century, has become a life skill that is urgently needed to be improved. Globally, the drive to enhance financial literacy involves integrating it into the education curriculum, necessitating educators’ comprehensive grasp of financial literacy education before imparting it to students. This research aims to outline a conceptual model of financial literacy professional development to improve teachers’ professional competence, employing a narrative review that synthesizes 28 relevant literatures retrieved from Scopus databases. The results of the study show that an effective training model for teacher professional development (TPD) in financial literacy education should focus on essential financial literacy content consisting of planning and budgeting, banking services, income and careers, insurance, investment, savings, also spending and credit. Furthermore, the main characteristics of TPD regarding financial literacy education should encompass content focus, coherence, ownership, active learning, duration, and collective participation.
The objective of this research is to examine teachers' competence in designing activities after engaging in professional development activities aimed at enhancing teaching design in order to develop students' thinking abilities that are contextually appropriate. The participants consist of 5 elementary school science teachers from schools. The research employed semi-structured interviews and classroom observation as research instruments. The findings reveal that teachers engaged in self-development through observation and learning from their peers within the community of practice (CoP). They receive advice and feedback from fellow teachers and apply these insights to improve their activities. Consequently, teachers are able to continuously refine and develop their teaching approaches to align with students' contexts. This approach facilitate diversification in thinking and learning management, as well as collaborative teamwork to enhance teaching methods. As a result, engaging and interesting thinking development activities are incorporated into student learning, along with the creation of a seamless learning-promoting environment. Collaborative teamwork in instructional design and problem-solving further afford teachers the opportunity for additional self-learning and personal development. This collaborative approach also contributes to fostering cognitive diversity and relieved the need for individual teachers to undertake all tasks independently.
Adaptive online learning can be realized through the evaluation of the learning process. Monitoring and supervising learners’ cognitive levels and adjusting learning strategies can increasingly improve the quality of online learning. This analysis is made possible by real-time measurement of learners’ cognitive levels during the online learning process. However, most of the currently used techniques for evaluating cognitive levels rely on labour-intensive and time-consuming manual coding. In this study, we explore the machine learning (ML) algorithms and taxonomy of Bloom’s cognitive levels to explore features that affect learner’s cognitive level in online assessments and the ability to automatically predict learner’s cognitive level and thus, come up with a recommendation or pedagogical intervention to improve learner’s acquisition. The analysis of 15,182 learners’ assessments of a specific learning concept affirms the effectiveness of our approach. We attain an accuracy of 82.21% using ML algorithms. These results are very encouraging and have implications for how automated cognitive-level analysis tools for online learning will be developed in the future.
This systematic literature review (SLR) aimed to investigate the potential of digital online game-based learning (DOGBL) to enhance motivation in English as a foreign language (EFL). Online gaming has grown in popularity among students, opening up the possibility of using games as powerful instructional resources. Academic achievement depends on motivation, and this study, led by self-determination theory (SDT), explored how external rules, like rewards and recognition, could increase motivation in EFL utilizing DOGBL. The study used the SLR method, examining databases and choosing articles based on predetermined criteria. The chosen publications were examined in-depth, and a preferred reporting items for systematic reviews and meta-analyses (PRISMA) diagram was employed for analysis. For results, DOGBL could enhance teaching EFL by providing flexible and interesting learning environments. Key elements in motivating in DOGBL included game design, personalization, social engagement, curricular integration, and instructor assistance. As a promising method to improve EFL instruction, game-based learning, especially DOGBL, saw considerable developments between 2018 and 2023. Thus, these ground-breaking techniques transformed the way people learn English vocabulary and provided a fun and engaging way to learn the language. For educators and students, the potential for DOGBL to change EFL education is still exciting as technology develops.
The development of postmodern-era technology in the world of education is increasingly sophisticated, thus impacting the character of students and their social environment. Technological progress negatively affects the lives of today's generation. When misuse of technology is widespread, it is imperative to strengthen cultural and religious filtration. So that the influence of globalization on technological development can be minimized. So as not to damage the cultural values and morality of students as the next generation of the nation. This study aims to explain the importance of transforming the values of Bima's local wisdom "Nggusu Waru" through the media of social studies e-books. The results and conclusions of this study are efforts to develop students' social character that require teacher collaboration, supervision, and optimal parental attention so that their interest in learning is higher and minimizes deviant behavior.

Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Developing Assessment Instrument as a Mathematical Power Measurement (Imam Kusmaryono)

disposition [4]. Meanwhile, reasoning, communication and connection are components of
mathematical power [8].
National Council of Teachers of Mathematics (NCTM) in the affirmation of “Vision of
Mathematical Power for All”, argued that problem-centered learning instructions for all students by
emphasizing on mathematical power development for all students and mathematical power should become
the integral parts of curriculum [5]. This is reaffirmed in content standard of Indonesian elementary and high
school curriculum 2013, stating that learning competence for mathematics is to have a trust on mathematical
power and mathematics usability, which are formed by learning experiences [9].
Many researches about mathematical power ability have been published, generally concluding that
student mathematical power on aspects of communication, connection and reasoning ability is still very low
[6], [3], [8]. It is because of inappropriate usage on learning model and on choosing assessment. Students’
mathematical power assessment should be in wide scoupe and include all aspects (cognitive, psychomotor,
and affective). Mathematical power assessment could not be considered as a separated and isolated
competence assessment [6]. Although one of mathematics knowledge aspects might be more emphasized
than the other in a certain assessment, it should be clear that mathematical power includes all aspects of
mathematics knowledge and its integration.
The latest survey results from OECD PISA in 2015, Indonesia is still in the bottom group that is
ranked 69 out of 76 countries surveyed [10]. The aspects surveyed by PISA in mathematics and science were
the abilities of understanding, problem solving, reasoning, and communication. Apparently, the tests
developed by PISA contains ability aspects of mathematical power. Based on PISA survey's ranking in 2015,
it could be interpreted that mathematical power ability of Junior High School students in Indonesia is
still low.
Referring to some researches conducted by experts and the result of OECD PISA survey, it is
suggested that test questions created by teachers should be under SOLO Taxonomy guidance based on grade
level. The questions should be non-routine problem-solving questions for the sake of mathematical power
development. According to the experts, teaching based on problem solving on one hand could contribute to
greater student thinking activities, which in turn showed greater activities during the class [11],[12]. On the
other hand, students’ problem solving ability became a measurement for students’ achievement in
learning mathematics [12].
One of recommended learning approaches to improve mathematical power ability is investigation-
based learning. By investigation, students could learn actively and explore mathematics tasks, and possibly a
logical solution might be acquired [13]. In short, a learning activity with investigation approach has improved
reasoning, communication and connection ability; while these three are the main components of
mathematical power [8].
Reviewing based on cognitive aspects of mathematical power and Structure of the Observed
Learning Outcomes (SOLO) Taxonomy, many of mathematics test questions composed by teachers
independently or in mathematics teachers’ forum still focus on routine issues and have not accommodated the
development and improvement of mathematical power and SOLO Taxonomy characteristics based on grade
level. Therefore, there has been a contradiction between program target and evaluation target. Besides, it is
clear that assessment is an integral part of learning process as well as a crucial part in improving the
effectiveness of learning [2].
Structure of the Observed Learning Outcomes (SOLO) Taxonomy is a hierarchial model which is
suitable for measuring subject learning result in different grades for all kinds of tasks [14-16]. SOLO
Taxonomy classifiesthe ability of students' responses to problems into 5 different hierarchical levels: pre-
structural, uni-structural, multi-structural, relational and extended abstract. When an assessment is
conducted in SOLO Taxonomy, the pre-structural level must be excluded from the thinking level, because at
that stage there is usually no opinion about the topic to learn, or the proposed ideas are irrelevant [15].
According to the experts [16], some criteria that could be used to determine whether a test question
includes to uni-structural, multi-structural, relational or extended abstract are as follows:
a. A question with Unistructural criteria has all information that could be instantly used to obtain a
solution.
b. A question with Multistructural criteria would implicitly need a formula to obtain a solution usingtwo
or more information and separated from what is in the question.
c. A question with Relational criteria provides all information but could not be instantly used to obtain a
solution. The solution is by connecting information provided using general principle or formula to
acquire new information. Then, based on the new information, solution would be obtained as the final
answer.

EduLearn Vol. 12, No. 3, August 2018 : 382 – 391

d. A question with Extended Abstract criteria provides all information or data, but could not be instantly
used to acquire final solution. The final solution could be obtained after synthesizing the new

Mathematics learning has much greater effort than just helping students to acquire problem solving
skill and strategy. Furthermore, teacher should attempt to develop positive disposition to learn mathematics –
aspects which have long-term effects in every things starting from students’ trust on mathematics [17] [18],
[19], including if mathematics would be their career choice or not [20]. Mathematical power assessment
should consider student mathematical disposition level in mathematics learning.
Based on experts’ findings (previous researches), it can be seen that mathematics learning in schools
has not succeeded significantly in improving mathematical power. It is because the learning model,
assessment form and assessment instruments have not been properly compiled according to mathematical
power indicators and SOLO taxonomy characteristic level. Therefore, it is necessary to emerge a new
formula that is an appropriate assessment model and test and non-test instruments to measure
mathematical power.
Model to Assess Mathematical Powerwas fundamentally developed by the authors [6] based on
portfolio assessment. Author [6] had developed a model to assess mathematical power, by conducting a test
based on mathematical power indicators. However, the test is in the form of multiple choices, and then it is
critisized as multiple choice tests which are quite inappropriate and considered not to be able to represent the
real mathematical power ability of students. Furthermore, in this research, mathematical power test is
developed in form of essays. On the other hand, NCTM document (1989) suggested a shift in assessment
practice that is to assess students' mathematical power entirely; not only from the facts of isolated knowledge
and skills [4, 21].
Assessment model developed in this research is a means to collect data in order to assess or measure
mathematical power level of students based on grade level. This assessment model could evaluate cognitive,
psychomotor and affective characteristic aspects, so that the measurement result could represent the progress
of their mathematical power. The model of mathematical power assessment is made into this following
scheme as presented in Figure 1.

Referring to the scheme of mathematical power assessment model based on the SOLO Taxonomy as
illustrated in Figure 1, this assessment model which will be implemented in schools should follow the
following steps: (1) determining the learning objectives, (2) determining the material according to the grade
level, (3) ) preparing the learning instruments (syllabus and lesson plan) and learning media, (4) preparing the
research instrument i.e. test instrument (essay writing test) compiled based on mathematical power ability
and SOLO Taxonomy level and non-test instruments (student activity observation sheets and interview
guidance books), (5) managing mathematics learning by applying learning models and approaches which can
improve and develop students' mathematical skills, e.g group investigation, discovery learning, inquiry,
problem based learning and other similar models, (6) observing student activities in learning, (7) conducting
essay writing tests, (8) conducting observation on students’ answer sheet to obtain data of students’ response
quality (9) conducting in-depth interviews on selected subjects (students) with purposive snowball sampling
technique, (10) recording, analyzing and describing interview results, (11) conducting a meta-analysis that is
combining and discussing the research result between quantitative and qualitative data, and (12) drawing
conclusions so that the level description and students' mathematical thinking construction can be obtained.
2. RESEARCH METHOD
This research used descriptive quantitative approach which was conducted through field
research [22]. The subjects of this research were 20 eighth graders in Sultan Agung Islamic Junior High
School 4 Semarang, Indonesia. The instruments developed in this research included test instruments (essay
items) and non-test instruments (guide book of observation on investigative activities [23] and mathematical
disposition questionnaires [17]). Quality of test items was reviewed its validity, reliability, difficulty and
discriminating power. Before tested, the test instruments’ construction were validated by expert team as the
reviewer. Data collection technique was conducted by test, documentation, and observation. Quantitative
analysis on the test items was based on the data from the items that had been tested.
The research procedure was conducted by following stages: (1) field (school) observation; (2)
determining research samples; (3) arranging research instruments; test instruments (written and essay
questions) referring to mathematical power ability and SOLO Taxonomy, and non-test instruments
(observation on students activity) which were compiled based on learning activity instruments; (4) research
instrument tests i.e. test and non-test instruments; (5) conducting analysis of instrument test result; (6)
arranging quantitative description; (7) providing conclusions; and (8) compiling research result report.
The development of mathematical power test instruments was conducted by two phases; arranging
test instrument and test instrument validation. These phases arethe improvement of ideas obtained from the
author’s previous research result [17]. The following is a scheme showing relevant activities for each phase
of developing test instruments as mathematical power measurement on Figure 2.

Phase 1. Instrument Arrangement: First phase in preparing mathematical power test items was a field
study by conducting observation and interview on mathematics teachers in schools and reviewing literature
on mathematical power from various sources. Then, a written test outline was prepared based on preliminary
data from the teachers and relevant literature review prepared. While arranging and assembling, test
instruments were re-evaluated based on peer and expert suggestion. Finally, the test was ready to be
conducted in the field (school).
Phase 2. Instrument Validation: Instrument analysis technique in the first stage i.e. validation test
was used to determine the validity level of test items. The formula used to determine the items’ validity was
Correlation Product Moment with variables [24]. The calculation of correlation coeffecient value was
consulted to the value of r product moment so it could be determined if the correlation is “significant or not”.
In second stage, the reliability of test items was calculated by Cronbach's Alpha formula [17]. After
the coefficient value of r11 was obtained, it was consulted to r product moment value. The instruments were
said to be reliable if r11 > rtable. The third stage was to analyze the difficulty level of the items. The item
instruments were compiled with high difficulty (hard), medium and easy levels with proportionally
determined percentages and considering SOLO taxonomy level criteria.
In fourth stage, it was to determine the discriminating power of the items. Discriminating
powermeansan ability of a question/item to distinguish between high-ability of students and low-ability of
students. To determine the discriminating power of the items, t test was used [17]. Value of count
t obtained
was then consulted to table
t value. The test instrument was said to be significant if value of count
t ≥ table
t with
5 % of trust level and dk = (n1 – n2).
Besides, non-test instruments in forms of learning activity observation sheets (investigative activities)
developed from the author's research [21, 23] (see appendix 2) and questionnaires (see appendix 3) were
compiled with appropriate indicators [17, 18], and then were tested to students in school. The validity and
reliability level of observation result data of student activities and the questionnaires were analyzed as steps
conducted in test instruments development phase [4, 25].
3. FINDINGS AND DISCUSSION
After completely compiled by the authorsbefore used as a test, the instrument test should be
constructively validated by the expert team consisting of Prof. Dr. Sunandar (reviewer 1), Dr. Rasiman
(reviewer 2), and Dr. Isnarto (reviewer 3). The reviewers conducted assessment with a scale of 1 to 5. The
assessment result was recorded on validation sheet represented in x
̄ score. The obtained average score (x
̄ )
shows the construction validity test of mathematical power ability implemented in learning.
Based on the results from expert team’s validation on test instruments, it was obtained that score for
each validation aspect was more than 4.20 and the total average score was 4.37. The results from reviewers’
assessment on test construction validity showed a very good category with a percentage of 87.4%.
Furthermore, it can be concluded that the test instrument is eligible for the research without any revisions.
Secondly, the instrument of written test consisting of 4 (four) items had been tested to 20 students.
The results of the test instrument were recorded and analyzed for each item. The results of the test item
validity used product moment correlation formula with 20 students as respondents with 5% significance
level. Item number 1 has rxy value = 0.985, number 2 has rxy value = 0.965, number 3 has rxy value = 0.970,
and number 4 has rxy value = 0.975.
An item is said to be valid if it showed rxy > rtable, and if rxy rtable then the item was invalid. The
Value of rtable for N=20 was rtable = 0.444. So 100% of the items are said to be valid, meaning that all four
items are in line with the criteria and not diverged from the reality. All those four items have valid criteria so
they could be used as the test instruments. The items could be instantly used or inserted to items file as
archieve. Calculation of realibility coefficient used Alpha formula with 5% significance level. The result
showed that the value of rtable was 0.444, and r11 was 0.974. The Interpretation of realibility coefficient (r11)
was on interval 0.70 r11 0.90 meaning that the instruments has high reliability.
Third stage testing was test item difficulty. The result of the item analysis on the difficulty level of
each question is the fourth question has a score between 0.25 to 0.75 with the category "medium" or "quite
difficult". There were four or 100% items on ‘medium’ or ‘quite difficult’ category. The fourth stage of
testing is the test of differentiation of test.
Based on the analysis that has been obtained that, the percentage of items with "satisfactory"
discriminatory power was 100% . The items with "satisfactory" discriminating power were those which had
discrimination index had 0.20 to 0.39. The result of this study was reinforced by the opinion of experts

saying that to determine the discriminatory powerof items was very important, because one of basic guidance
to arrange test items was to assume that students in class had different ability [24].
This research used four test items. These fouritems represented the types of questions on aspects of
mathematical power ability: reasoning, mathematical connection, and mathematical communication. Criteria
of the items used were valid, reliable, having good discriminatory power, and considering the difficulty level
of each item. The following table presents the matrix of item qualification used to measure mathematical
power based on SOLO taxonomy.

Table 1 provides data indicating that the four chosen items are qualified to be used as written test
instruments to measure student mathematical power. The four items have met the aspects of mathematical
power, and SOLO Taxonomy based on the grading level with a good discriminatory power, proportional
difficulty level, and also high validity level and realibility level (see appendix 1).
The outline for test items which was developed for four written test items has met mathematical power
ability aspects: reasoning, mathematical connection and mathematical communication, and has met
characteristics in SOLO Taxonomy based on VIII grade and intended learning outcomes (ILO) levels:
relational and extended abstract level [16]. Besides, the result of mathematical power ability test indicated
that the highest score was 85, the lowest score was 50, and the average score was 67. These result indicated a
fairly good category. The validity test was performed by observing construction process of arrangement
mathematical power research instruments using outline (see appendix 1). In the outline, all aspects were
included.They are 3 aspects of mathematical power ability.
Based on the analysis of observation sheets of activity investigation (appendix 2), all indicators of
observation sheets in 20 items are valid andreliable. The reliability test showed the value of r = 0.912. That
value was above rtable value on 0.444 with 0.05 significance level and sample n = 20. Meanwhile, the analysis
on mathemathical disposition quistionnaires (appendix 3) pointed out information that all indicators of
mathematical disposition in 20 items were valid and reliable. The reliability test on the questionnaires
showed the value of r = 0.770. That value was above r (table) value on 0.444 with 0.05 significance level
and sample n = 20. Thus, the reliability aspect of the instruments had completed. Then, a better reliability and
validity test was performed in the next stage, on much greater samples and should was socialized.
4. CONCLUSION
Based on the testinthe field andthe analysis of instrument qualification, it could be concluded that:
(1) the steps in the model (scheme) to assess mathematical power could be performed well without any
obstacles, so it could be said that this assessment scheme model could be used as a tool to assess
mathematical power, (2) test and non-test instruments are valid and reliable, and (3) prototypes of test and
non-test instruments could be used as a measurement in mathematical power assessment. Result of this study
could be instantly used by teachers as well as students at school, or as a reference in the assessment in order
to develop mathematical power.Then, if the model (scheme) will be used as a measurement, the author
suggest as follows: (a) Assessment on student mathematical power should be performed thoroughly,including
cognitive, psychomotor, and affective aspects; (b) Test items should be in forms of non-routine problem
solving referring to development of student mathematical power and considering characteristic competence
in SOLO Taxonomy based on grade level; (c) Teacher should be optimal as a facilitator in the learning; (d)
Usage of instruments in investigative activity observation should be performed repeatedly in order to obtain
accurate and representative data.
