Embedded System Practicum Module for Increase Student Comprehension of Microc...TELKOMNIKA JOURNAL
The result of applying the embedded system in education for students is successfully applied in
university. On the other side, many people in Indonesia use smart equipment’s (Hand phone, Remote), but
none of those equipments are used in education. University as the source of knowledge should overcome
the problem by encouraging the students to use a technology with learning about it first. Embedded
System Practicum Module Design needs a prototype method so that the practicum module that is desired
can be made. This method is often used in real life. A prototype considered of a part of a product that
expresses logic and physical of external interface that is being displayed and this method will fully depend
on user contentment. Embedded System Practicum Module Design is made to increase student
comprehension of embedded system course and to encourage students to innovate, so that many
technologies will be developed and also to help lecturers deliver course subjects. With this practicum it is
hoped that the student comprehension will increase significantly. The result of this research is a decent
practicum module, hardware or software that can help students to know better about technology and the
course subjects so that it will encourage the students to create an embedded system technology. The
result of the test has been done; there is an increase of learning value obtained by 7.8%.
A New Active Learning Technique Using Furthest Nearest Neighbour Criterion fo...ijcsa
Active learning is a supervised learning method that is based on the idea that a machine learning algorithm can achieve greater accuracy with fewer labelled training images if it is allowed to choose the image from which it learns. Facial age classification is a technique to classify face images into one of the several predefined age groups. The proposed study applies an active learning approach to facial age classification which allows a classifier to select the data from which it learns. The classifier is initially trained using a small pool of labeled training images. This is achieved by using the bilateral two dimension linear discriminant analysis. Then the most informative unlabeled image is found out from the unlabeled pool using the furthest nearest neighbor criterion, labeled by the user and added to the
appropriate class in the training set. The incremental learning is performed using an incremental version of bilateral two dimension linear discriminant analysis. This active learning paradigm is proposed to be applied to the k nearest neighbor classifier and the support vector machine classifier and to compare the performance of these two classifiers.
Predicting the Presence of Learning Motivation in Electronic Learning: A New ...TELKOMNIKA JOURNAL
Research affirms that electronic learning (e-learning) has a great deal of advantages to learning process, it’s provides learners with flexibility in terms of time, place, and pace. That easiness was not be a guarantee of a good learning outcomes though they got the same learning material and course, because the fact is the outcomes was not the same from one to another and even not satisfy enough. One of prerequisite to the successful of e-learning process is the presence of learning motivation and it was not easy to identify. We propose a novel model to predicting the presence of learning motivation in e-learning using those attributes that have been identified in previous research. This model has been built using WEKA toolkit by comparing fourteen algorithms for Tree Classifier and ten-fold cross validation testing methods to process 3.200 of data sets. The best accuracy reached at 91.1% and identified four parameters to predict the presence of learning motivation in e-learning, and aim to assist teachers in identify whether student needs motivation or does not. This study also confirmed that Tree Classifier still has the best accuracy to predict and classify academic performance, it was reached average 90.48% for fourteen algorithm for accuracy value.

Research: Is Series Teaching as Effective as Simultaneous Teaching?Jeanelei Carolino
This document discusses a study that compared the effectiveness of series teaching versus simultaneous teaching. The study was conducted with 38 grade 8 students in Ozamiz City National High School. Students were split into two groups - one exposed to series teaching (experimental group) and one to simultaneous teaching (control group). Both groups were given a lesson and posttest to measure their demonstration of knowledge in using computer applications and explaining processes. Statistical analysis found no significant difference in scores between the two groups, supporting the hypothesis that series teaching is as effective as simultaneous teaching. The results imply that limitations in computer access do not hinder the teaching-learning process, as long as experiential learning occurs through either series or simultaneous teaching.

In education, the use of electronic (E) examination systems is not a novel idea, as Eexamination systems have been used to conduct objective assessments for the last few years. This research deals with randomly designed E-examinations and proposes an E-assessment system that can be used for subjective questions. This system assesses answers to subjective questions by finding a matching ratio for the keywords in instructor and student answers. The matching ratio is achieved based on semantic and document similarity. The assessment system is composed of four modules: preprocessing, keyword expansion, matching, and grading. A survey and case study were used in the research design to validate the proposed system. The examination assessment system will help instructors to save time, costs, and resources, while increasing efficiency and improving the productivity of exam setting and assessments.

The proliferation of technology has re-defined the traditional learning environment. The classical
classroom model of teacher to student delivery is changing as technology becomes more pervasive in
educational environments. In addition, the availability of technology and the breadth of different device
categories and platforms is a stark contrast to the traditional classroom, and the pervasiveness of low-cost
devices provides opportunities to significantly re-define the learning environment. In this paper, we have
developed a real-time feedback mechanism supported by technology to allow students and educators to
assess comprehension in the teaching environment. Real-time feedback is input that is acquired whilst a
teaching practice is ongoing, and the outcomes derived from the feedback mechanism have provided a
strong pedagogical value to the learning environment. These benefits have been clearly elicited by the

Augmented reality: effect on conceptual change of scientificjournalBEEI
In recent years, Augmented Reality (AR) has received increasing emphasis and researchers gradually promote it Over the worlds. With the unique abilities to generate virtual objects over the real-world environment, it can enhance user perception. Although AR recognised for their enormous positive impacts, there are still a ton of matters waiting to be discovered. Research studies on AR toward conceptual change, specifically in scientific concept, are particularly limited. Therefore, this research aims to investigate the effect of integrating AR on conceptual change in scientific concepts. Thirty-four primary school students participated in the study. A pre-test and post-test were used to assess participants’ understanding of the scientific concepts before and after learning through AR. The findings demonstrated that 82% among them had misconceptions about the scientific concepts before learning through AR. However, most of them (around 88%) able to correct their misconceptions and shifted to have a scientific conceptual understanding after learning through AR. These findings indicate that AR was effective to be integrated into education to facilitate conceptual change.
This study evaluated the impact of blended learning incorporating video feedback on student performance in a medical laboratory science program.

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 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.

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.

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. This research method uses research and development design. At the stage of preliminary studies with models developed by Borg and Gall. Through several stages of research, information gathering, development of initial forms of products, and initial field testing. In this step, data is collected through interviews, observation and documentation. The data is analyzed to find out some of its weaknesses and shortcomings.

The effect of virtual reality laboratory on conceptual understanding in… Afsari Amiati

The laboratory is a way to understand the concepts obtained from practicum used to solve problems
related to previously owned concepts that are not understood by students. Understanding of concepts is one
of the learning outcomes that students will receive after the teaching process which is on cognitive shutter
that has the domain of thinking, knowing, and solving problems. However, not all schools have adequate
laboratories so a media that can overcome this is needed. Technological advancements provide solutions for
improving the quality of learning. Related to this, a virtual laboratory was developed so that technology-
based learning as a solution to simulate experimental activities in the laboratory. Virtual laboratory is a media
that helps students by providing an interactive experience in observing and manipulating objects, the system
produced, data and phenomena to fulfill the learning taught [7]. Interactive diving is supported by an
interactive environment that is presented in a virtual laboratory in the form of a playground for experiments
in the virtual world. The program is a domain-based simulation program in the form of an experimental unit
with data files and tools operating on objects in a virtual environment [8].
Virtual Laboratory is a supporting factor to enrich experience and motivate students to conduct
experiments interactively and develop experimental skills activities. Thus, virtual laboratories can be called
as a series of programs that can visualize abstract or complex phenomena carried out in real laboratories, so
as to increase learning activities in an effort to develop skills needed in problem solving [9]. The use of
virtual laboratories has the advantage of being able to do it anywhere and anytime and students can do
experiments safely if the actual experiments are dangerous. The use of this laboratory is also cheaper
compared to real laboratory experiments because it requires relatively expensive tools and materials [10, 11].
Previous research has shown that laboratories improve independence and understanding the concepts of
learners in learning [12] and virtual laboratories are more effective to use than classical teaching [13]. In
addition, virtual laboratories can be used in conceptual learning [14] and learning innovations [15].
2. RESEARCH METHOD
This research used the experimental method (Quasy experiment) with post-test only design [16].
The media used was developed using a development model adopted from the ADDIE [17] development
model which stands for Analysis, Design, Development, Implementation, and Evaluation. The aim of which
is to determine the effect of VR-Lab media on students' conceptual understanding in the concepts of
electrolytes and non-electrolytes in chemistry. Products developed in the form of software with Android
operating system (.apk) are run using an Android smartphone and Virtual Reality glasses (VR-Box). The trial
design can be seen in Table 1.

The research data was collected using conceptual understanding sheets. The question sheet for
understanding chemical concepts in electrolytes and nonelectrolytes used a type of multiple choice question
with 40 questions and each had 5 choice questions. Before testing the problem, it was first carried out
empirical validity of the conceptual understanding sheet using 3 schools in Barru district (South Sulawesi-
Indonesia). The first school used 3 different classes from the school which was the subject of the study,
namely SMA Negeri 1 Barru, the second school used used 4 classes namely SMA Negeri 3 Barru, and the
third school used 2 classes namely SMA Negeri 6 Barru. The number of subjects in this empirical validity
was 250 students. Validity and reliability and item fit data will be measured using the QUEST program.
While for the research class using 3 classes consisting of control classes as many as 29 students, media
classes 27 students, and mix classes as many as 28 students. Testing the hypothesis in the study using one-
way ANOVA statistical analysis techniques using the SPSS 22 program.

3. RESULTS AND ANALYSIS
3.1. Media development
The VR-Lab developed was a VR-Lab that was different from previous VR-Labs which only used
computers or mobile phones. As in previous studied [12, 18] and previous virtual laboratory development.
The VR-Lab developed was a virtual reality laboratory that applies 3D interactions using VR-Box and
controller as supporting applications that exist in Android smartphones that come in .apk. This VR-Lab was
an application developed using Blender and Unity software. Blender served to create a 3D laboratory room
and 3D objects in a virtual laboratory. Whereas, Unity had a function as a developer application in the 3D
interaction process in VR-Lab so that this application could be combined with a VR-Box. The VR-Lab
developed simulated electrolyte and non-electrolyte practicum-based practicum in a virtual reality laboratory.
The appearance of the application developed can be seen in Figure 1, Figure 2, and Figure 3.

3.2. Empirical validation of questions instrument
Instruments about conceptual understanding used in the assessment were first carried out expert
validation before used. The results of expert validation on the problem of understanding the concept were
declared feasible to use with a revised note first. The next step was the empirical validation using 250
students from 3 schools. The results of these tests carried out instrument reliability and item fit using the
QUEST program. The reliability of the question shown that the concept of conceptualization had a reliability
value of 0.96. Reliability results can be seen in Figure 4.

3.3. The implementation of VR-Lab Media
The next process was the implementation of VR-Lab media that could be used as a medium in data
collection in research. This study used 3 different classes taken from grade in SMA Negeri 1 Barru. The first
class was a class using ordinary practicum or without using VR-Lab media in practicum (control class), the
second class was experimental class I which was the class that used VR-Lab media in the practical process
(media class), and the third class was experimental class II namely classes that used ordinary laboratoriy that
were combined with the used of VR-Lab media in the practical process (mix class). The learning process
using or without VR-Lab can be seen in Figure 6.

The results of the implementation process were carried out in the classroom by taking data on
students' conceptual understanding by carrying out the posttest process on 3 research classes using
instruments that had been approved empirically. Results of the average posttest value Understanding the
concepts of students from three classes can be seen in Figure 7.
Figure 7. Difference in average of conceptual understanding
The number of each sample in 3 classes, the comparison of the average, standard deviation,
minimum and maximum values of each class can be seen in Table 2.

Total 84 53.0714 15.92398 22.50 92.50
3.4 Statistical Tests
Statistical tests were then conducted to determine the effect of VR-Lab by conceptual understanding
students' concepts. Test statistic used by one-way ANOVA statistical test using the SPSS 22 program. Before
the ANOVA test, the normality prerequisite test was carried out using Shapiro-Wilk. The results of this test
can be seen in Table 3.

The analysis results shown that the Sig. > 0.05, it could be concluded that the research data was
normally distributed so that further analysis could be carried out, namely analysis of ANOVA.
Another prerequisite test besides the normality test is the homogeneity test. The homogeneity test used in the
analysis was Levene Statistics. The test results can be seen in Table 4.
Table 4. Homogeneity test results

Based on the results of the Levene Statistics value of 0.559 with a significance (sig.) of 0.574.
Because of the sig value. 0.574> 0.05, it could be concluded that the variants of the three classes
tested/compared were the same or homogeneous. Furthermore, ANOVA analysis to find out whether the
three class groups had differences in understanding significant concepts or not. ANOVA test results can be
seen in Table 5.

Based on the table it can be seen that the sig value. that is 0.000 < 0.05 so it can be concluded that
the average of the three groups of classes is "DIFFERENT" significantly. Further analysis of ANOVA was a
Post-Hoc test using the Bonferroni test with the aim of conducting multiple comparison tests to determine
whether the three averages or more differed significantly in the number of analysis variants. The results of
the Post-Hoc test analysis can be seen in Table 6.

In the table it was known that the average difference for the control class and media was -0.75287
(difference from descriptive output). The average difference ranges from -8.3133 (lower bound) to 6.8075
(upper bound) at a 95% confidence level. There were differences or not seen from the sig value. Based on
these data it was known that the value of sig 1.000> 0.05, it could be concluded that between the control class
and the media was the same or no significant difference. Whereas, the class that had a significant difference
was between the control class and the mix class, and the media class and mix class, namely sig 0.000 <0.05
which proved that there were significant differences.
The use of technology-based learning media is highly highlighted in the 21st century learning style
that is centered on the advancement of information technology (IT). IT-based learning media have been
developed so that it can be used as a support in learning so that it can improve student learning achievement
[19], learning independence and understanding of students' concepts [12]. IT-based learning media can be
applied as an alternative in carrying out practicum, Practicum that can be applied is a laboratory-based virtual
lab. Virtual laboratories can be utilized in assisting learning processes specifically for chemistry that require
experiments such as electrolyte and non-electrolyte materials. This learning media makes it easier for
students to understand lessons that can be used as independent learning media that can be accessed inside and
outside the classroom.
This is in accordance with the results of the research that has been conducted which proves that the
experimental class II has a higher understanding value with other classes. Can be used to conclude the use of
VR-Lab combined with conventional practicum is very good in improving students' understanding. Can be
used as a simulation media / supplement before doing a real lab. The application of VR-Lab as a supplement
media to help ordinary labors can answer the weaknesses of the VR-Lab itself which makes improving the
ability of students because they do not do lab work such as pouring solutions, measuring properly using
actual practicum tools [20]. Learning the application of learning as in experimental class II is very effective.
In addition to supplements, VR-Lab can be used as a substitute for ordinary practicum as in the
results of research that prove that the VR-Lab class and practicum VR-Lab practicum class are approved by
practicum can be used to assist experiments conducted so that it is carried out safely. The use of VR-Lab can
also be done by practicum which will be carried out using relatively expensive tools and materials [10]. VR-
Lab also has the advantage of being able to work anywhere and anytime and do not need tools and chemicals.
VR-Lab can also change components such as particle movement, particles, interactions between particles,
changes in material structure due to the influence of the environment or reading data in the form of numbers
and changes directly. Learning media like this make it easier for students to understand lessons that can be
used as independent learning media that can be accessed inside and outside the classroom. This learning
media can be integrated with learning methods that are complemented by technological advances through
online learning systems and traditional methods [21].
This VR-Lab can be introduced as a system that can be used to support systems running
conventional laboratories. VR-Lab provides opportunities for students to experiment with or without access
to the internet so students do not need to be present to discuss experiments in the laboratory. This kind of

learning is effective because students can learn on their own actively without an instructor or assistant and
unlike the current system. The importance of using laboratories can help students to support laboratory
activities that have the potential as learning media that contribute to student learning outcomes that are
important from science learning [22].
4. CONCLUSION
The results of the VR-Lab implementation are carried out using 3 different classes, namely the
control class (ordinary practicum), experimental class I (VR-Lab media class) and experimental class II
(ordinary practicum and VR-Lab media) in terms of understanding the concept of students giving results,
namely from the class with VR-Lab as a supplement (experiment II) has a significant difference with the
class using a laboratory without media (control class). Meanwhile, for classes that use VR-Lab as an
experiment (experiment I) does not has a significant difference. So that it can be said that media practicum
can be used as a substitute and complement of ordinary practice.
