This paper discusses aspects of interpretation of graphs including those related to the interface between
different contexts of interpretation. Particularly it is discussed the notion of Critical Sense as a skill to analyse data its
interrelations rather than simply accepting the initial impression given by the graph. We suggest that Critical Sense in
graphing can help readers to balance several aspects involved interpretation of media graphs in certain contexts. This
paper also presents initial findings from our analyses of study with student teachers interpreting media graphs. We
are concerned to study Critical Sense in student teachers as a way of helping us, and them, think about teaching and
learning graphing in ways that will support the development of Critical Sense.
1) The purpose of this study was to examine the relationship between visual static models and students' written solutions to fraction problems using a large sample of student work.
2) The results indicate that common student errors relate to how students interpret the given model or their own model of the situation. Students' flexibility with visual models is related to successful written solutions.
3) Researchers hypothesize that exposure to varied mathematical representations influences students' ability to flexibly use static visual representations. Students need a solid understanding of real-world situations to successfully create and interpret visual models.
This document summarizes a research study that examined the relationship between Polya's problem-solving steps and the steps of computational thinking when students solve mathematics problems. The study found that when defining the problem, students performed abstraction and decomposition, consistent with computational thinking. When planning solutions, students used generalization. When implementing plans and checking answers, students used debugging and developing algorithms. So the study concluded that Polya's problem-solving aligns with computational thinking steps when students solve problems in mathematics.

The document analyzes the cognitive and metacognitive mathematical problem solving skills of 67 African American 3rd and 4th grade students. The students showed somewhat low metacognitive prediction and evaluation skills. They performed lower on multi-sentence word problems involving contextual information, relevant information selection, and mental visualization than on simple computational problems. To improve, these students need targeted instruction on multi-sentence problems and developing their ability to predict strategies and reflect on solutions.
This document summarizes a study that investigated the relationships between mathematics attitude, academic motivation, intelligence quotient, and mathematics achievement. The study involved 1670 high school students in Iran. It found that mathematics attitude, academic motivation, and intelligence quotient were all positively correlated with mathematics achievement. A multiple regression analysis determined that mathematics attitude and intelligence quotient significantly predicted mathematics achievement, but academic motivation was not a significant predictor when the other variables were accounted for. The study also found that while there were no significant gender differences in the other variables, males scored higher than females in mathematics achievement.
The document discusses basics of statistics including key concepts like population, sample, parameters, and statistics. It provides definitions for population as the collection of all individuals or items under consideration, and sample as the part of the population selected for a study. Parameters describe unknown characteristics of the population, while statistics describe known characteristics of the sample and are used to infer parameters. The document also distinguishes between descriptive statistics, which summarize and organize data, and inferential statistics, which draw conclusions about populations from samples.

Applying statistical dependency analysis techniques In a Data mining DomainWaqas Tariq
Taking wise career decision is so crucial for anybody for sure. In modern days there are excellent decision support tools like data mining tools for the people to make right decisions. This paper is an attempt to help the prospective students to make wise career decisions using technologies like data mining. In India technical manpower analysis is carried out by an organization named NTMIS (National Technical Manpower Information System), established in 1983-84 by India's Ministry of Education & Culture. The NTMIS comprises of a lead center in the IAMR, New Delhi, and 21 nodal centers located at different parts of the country. The Kerala State Nodal Center is located in the Cochin University of Science and Technology. Last 4 years information is obtained from the NODAL Centre of Kerala State (located in CU-SAT, Kochi, India), which stores records of all students passing out from various technical colleges in Kerala State, by sending postal questionnaire. Analysis is done based on Entrance Rank, Branch, Gender (M/F), Sector (rural/urban) and Reservation (OBC/SC/ST/GEN).
In recent years an attempt has been made to outline the cognitive profile of children with Autistic Spectrum Disorders (ASD) in mathematics. The differentiation of the qualitative characteristics of the mathematical performance of the child with the ASD in activities related to Early Mathematical Competence compared to typical development children, the level of performance of the relational tasks, compared with the enumeration tasks and the role of the function of illustration in solving verbal addition and subtraction problems process an area of particular research interest as they are directly linked to the development of educational approaches. The purpose of this research is to investigate the Early Mathematical Competence of a child with ASD with an emphasis on the knowledge and skills that are essentially about creating the concept of number. For the purposes of investigating the above purpose, a qualitative approach was used. More specifically, Utrecht's Early Mathematical Competence Criterion was administered to the child who participated in the research. In addition, the unstructured observation was used to record the difficulties of the student at the completion of the tests, the possible avoidance strategies and the time of completion of the activities, as well as the structured interview with one of the parents of the child in order to delimit the case. The results obtained from the qualitative analysis of the data demonstrate the existence of significant difficulties in relational tasks compared to the enumeration tasks, and in particular, the ability of the serial match was not developed since these abilities are linked to the concept of quantity conservation. The results of the research lead to the conclusion that children with ASD have a particular cognitive profile in mathematics which does not correspond to the typical development of logical-mathematical thinking.

The document summarizes and analyzes several research papers on using visualization as a learning tool in mathematics education. It discusses how the papers investigate visualization from an epistemological perspective. Key findings include: 1) Visual representations like number lines are open to various interpretations by students and benefit from social interaction; 2) Technology allows dynamic visualization that reveals multiple meanings; 3) Visual metaphors can be overgeneralized if not addressed by teachers. The analysis highlights the importance of considering individual differences in visualization preferences and avoiding claims about universal efficacy of visual tools.
The document discusses a reference model for learning analytics with four dimensions:
1) Data and environments - what data is collected from what sources
2) Stakeholders - who are the people involved (learners, teachers, institutions)
3) Objectives - why is the data being analyzed (understanding learning, optimizing environments)
4) Methods - how the data is analyzed (data mining, statistics, visualization)
The document reviews related fields like academic analytics, educational data mining, and personalized learning, and proposes that learning analytics draws upon methods from these areas.
An approach for discrimination prevention in data miningeSAT Journals
Abstract In the age of Database technologies a large amount of data is collected and analyzed by using data mining techniques. However, the main issue in data mining is potential privacy invasion and potential discrimination. One of the techniques used in data mining for making decision is classification. On the other hand, if the dataset is biased then the discriminatory decision may occur. Therefore, in this paper we review the recent state of the art approaches for antidiscrimination techniques and also focuses on discrimination discovery and prevention in data mining. On the other hand, we also study a theoretical proposal for enhancing the results of the data quality. Keywords- Antidiscrimination, data mining, direct and indirect discrimination prevention, rule protection, rule generalization, privacy.

Zhang,yixin investigating effectiveness of using handheld computers nftej v21...William Kritsonis
This document summarizes two experimental studies that examined the effectiveness of using handheld computers to help 4th and 5th grade students learn mathematics. The first study found that 5th grade students who used handheld computers to learn fraction multiplication performed better than those who did not. The second study found that 4th grade students who used handheld computers to learn least common multiple also performed better. The document reviews other relevant literature on using handheld computers in education and concludes that while results are mixed, handheld computers show potential to increase student engagement and support learning, especially for weaker students. More research is still needed to fully understand how handheld technology can best be utilized across different subject areas.
This document summarizes a research paper on mathematical skills in individuals with autism spectrum disorder (ASD). It discusses:

2. Recent studies have explored numerical/computational skills in some low-functioning individuals with ASD, but mathematical competence in high-functioning ASD is less understood. A particular cognitive pattern in ASD may benefit development of "savant" skills like mathematics, but more research is needed.
3. The paper aims to examine the range of mathematical abilities in individuals with ASD and investigate
Waste Thermocol to Adhesive for Better EnvironmentAM Publications
Plastic waste causes serious health and ecological problems like breeding places for mosquito’s, being
eaten by cattle and wild animals to endanger their lives, where it lays it stop vegetation from growing, create obstructs
in drain and piping, etc. Now total consumption of plastic has reached to 100 million tons, and this has caused
significant depletion of natural resources such as petroleum and natural gas. Plastics make up almost 13 percent of
the municipal solid waste stream, a dramatic increase from 1960, when plastics were less than one percent of the
waste stream. 32 million tons of plastic waste was generated in 2011, representing 12.7 percent of total MSW.
Annually approximately 500 billion plastic bags are used worldwide. More than one million bags are used every
minute. A work is carried out to convert waste thermocol to useful product i.e. Adhesive.
1) Gandhi faced discrimination and hardship from a young age. He was punished unfairly in school and struggled to fit in, which led him to focus on his studies instead of social activities.
2) As a young man, Gandhi experimented with behaviors against his religion like meat-eating and smoking due to peer pressure. He later realized the errors of his ways.
3) Gandhi's nonviolent protests and civil disobedience campaigns in South Africa and India helped achieve greater rights and independence for Indians and other groups facing discrimination. His leadership inspired millions and led to India's independence through nonviolent means.

A Structural Model Related To The Understanding Of The Concept Of Function D...Cheryl Brown
1) The document discusses a study that examines secondary students' understanding of the concept of function across three dimensions: definition, representation (recognition and interpretation), and problem solving.
2) Confirmatory factor analysis confirmed these four dimensions comprise the conceptual understanding of functions. The ability to define the concept was found to influence performance on the other dimensions.
3) The study aims to verify the proposed theoretical structure of conceptual understanding of functions and examine how the dimensions are interrelated, as well as identify differences in student performance at different grade levels.
The current educational research conducted in the context of special education is an attempt to ascertain whether conceptual maps enhance memory and help a child with special learning difficulties in understanding a theoretical lesson, such as the lesson of history. That is why a first-grade Junior high school student diagnosed with special learning difficulties is chosen, who was discouraged by his ineffectual attempt to understand and retrace the lesson of history no longer showed any interest in the lesson. In the framework of this qualitative research, in order to verify the effectiveness of the conceptual maps, a personalized intervention is made in the lesson of history for the student of the first grade, constructing the conceptual maps on the computer with the help of the software program "Inspiration 9". The lessons were based on the book of the history of first-grade Junior high school and refer to the Classical era in Athens. The intervention program lasted five weeks and the student actively participated in this. Upon completion of the intervention, as well as the student's answers to the same test on the 5th and 7th week of intervention, together with the information given to us by the school teacher and the special education teacher in the integration section, verified the valuable help of conceptual charts in this lesson. In particular, their effectiveness in the field of education and in particular of special education was established and the conditions necessary for conceptual charts to help as much as possible in teaching were explored.

This study applied a content analysis method to compare how the algebraic topic of using symbols for unknown quantities is presented in elementary school mathematics textbooks from Taiwan (Nani), Singapore (My Pals Are Here!), and Finland (Laskutaito). Specifically, differences in question types (purely mathematical, verbal, visual, or combined representation), contextual versus noncontextual presentation, and pedagogical content design were compared. The findings showed that (1) fewer visual representations are found in Nani compared with the other textbooks; (2) Taiwan uses more contextual problems than the other countries; and (3) the content design in Taiwan focuses on applying the equivalent axiom to solve for unknown quantities, whereas Singapore and Finland use line segments or divide concepts in geometry graphs. In addition, the Singaporean textbooks teach algebraic simplification, providing this topic earlier than the other countries and enabling students to form connections with junior high school learning. Other implications of this study are discussed, and suggestions for future research are provided.
This study examined how different types of 3D visualizations (interactive 3D animation, 3D animation, and static 3D illustrations) combined with narration and text affect learning among 212 eighth grade students in Greece. The study tested an interactive multimedia application on methods of separating mixtures that was produced in three versions differing only in the type of visualization. The results showed that versions with interactive 3D animations and 3D animations increased student interest and engagement. However, the version with static 3D illustrations allowed students more control over their learning pace and placed less cognitive load on working memory.

This document provides an overview of Russell Francis's doctoral thesis investigating the implications of media change for learning. The thesis explored how learners are appropriating new media to support learning through two design experiments and an ethnographic study of advanced learners. The ethnographic study identified six genres of practice used by learners and attempted to develop conceptual tools to understand new media literacies. The thesis argues that media convergence has decentralized formal education and learners now need new media literacies to design personal learning environments leveraging online resources.
Assessing Numeracy In The Upper Elementary And Middle School YearsMartha Brown
This document discusses assessing numeracy skills in upper elementary and middle school students. It notes that while numeracy is an important life skill, most research focuses on early childhood or adult populations, not this age group. It introduces a new numeracy scale designed for upper elementary and middle school students. The scale was validated on a diverse sample of 197 students, and showed strong correlations with other cognitive and math achievement tests, supporting its construct validity. A preliminary analysis also found some numeracy skills correlated positively with students' self-reported creative problem solving and diligence. The document argues that more research is needed on developing numeracy in this understudied age range.

PEDESTRIAN DETECTION IN LOW RESOLUTION VIDEOS USING A MULTI-FRAME HOG-BASED D...AM Publications
Detecting pedestrians in low resolution videos is a challenging task, due to the small size of pedestrians in the images and the limited information. In practical outdoor surveillance scenarios the pedestrian size is usually small. Existing state-of-the-art pedestrian detection methods that use histogram of oriented gradient (HOG) features have poor performance in this problem domain. To compensate for the lack of information in a single frame, we propose a novel detection method that recognizes pedestrians in a short sequence of frames. Namely, we take the single-frame HOG-based detector and extend it to multiple frames. Our detector is applied to regions containing potential moving objects. In the case of video taken from a moving camera on an aerial platform, video stabilization is first performed to register the frames. A classifier is then applied to features extracted from spatio-temporal volumes surrounding the potential moving objects. On challenging stationary and aerial video datasets, our detection accuracy outperforms several state-of-the-art algorithms.

EFFECT OF SILICON - RUBBER (SR) SHEETS AS AN ALTERNATIVE FILTER ON HIGH AND L...AM Publications
A digital radiography delivers a radiation dose to patients; therefore it poses potential risk to the patients. One effort to reduce dose is carried out using a radiation filter, e.g. Silicone Rubber (SR) sheet. The purpose of this research was to determine the impact of the SR sheet on the high contrast objects (HCO) and the low contrast objects (LCO). The dose reduction was determined from attenuation x-rays before and after using the SR sheet. Assessment of HCO and LCO was observed from CDR TOR phantom at tube voltage of 48 kVp and tube current of 8 mAs. The physical parameter to assess image quality was the Signal to Noise Ratio (SNR) value in LCO. The maximum x-ray attenuation using the SR sheet is 48.82%. The visibility of the HCO remains the same, namely 16 objects; however the LCO slighly decreases from 14 objects to 13 objects after using the SR sheet. The SNR value decreases with an average value of 15.17%.Therefore, the SR sheet as a alternative filter has no effect on the HCO and has realtively little effect on the LCO. Thus, the SR sheet potentially is used for radiation protection in patients, especially on examinations that do not require low contrast resolution.

ANALYSIS ON LOAD BALANCING ALGORITHMS IMPLEMENTATION ON CLOUD COMPUTING ENVIR...AM Publications
Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. The elements involved in cloud computing are clients, data center and distributed server. One of the main problems in cloud computing is load balancing. Balancing the load means to distribute the workload among several nodes evenly so that no single node will be overloaded. Load can be of any type that is it can be CPU load, memory capacity or network load. In this paper we presented an architecture of load balancing and algorithm which will further improve the load balancing problem by minimizing the response time. In this paper, we have proposed the enhanced version of existing regulated load balancing approach for cloud computing by comping the Randomization and greedy load balancing algorithm. To check the performance of proposed approach, we have used the cloud analyst simulator (Cloud Analyst). Through simulation analysis, it has been found that proposed improved version of regulated load balancing approach has shown better performance in terms of cost, response time and data processing time.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
