Abstract

This research aim to learn and analyze the capability of student’s mathematical connection in circle major. The data collected are instrumen test result and interview result with several student’s who are chosen randomly. The method of this research use qualitative descriptive method. The population of this research are second grade student’s of Junior High School in Madani Boarding School West Bandung. Based on the capability of mathematical connection test result the first indicator are finding relation among various representation concept and prosedure, then aunderstanding the relation in mathematic topic, the presentage are 41%. While the second indicator are understanding the representation of the same equivalen concept, the presentage are 70%. The third indicator presentage, use math in others study field or in daily life. Each presentage are 23%, 21%, 43%, and 35%. Meanwhile for the fourth indicator, use the evaluate the connection between math topic with the topic outside are 95%. Beside that interview result show some of difficulties faced by student’s in doing mathematical connection problem are 1) can’t understanding what the purpose of the question, 2) confuse with the formula that should be used, 3) error in using arithmatic operation.Keyword : mathematical connection, circle

Abstract

Education is a conscious and planned effort organized by school institutions to guide and train learners to grow awareness about the existence of life and the ability to solve every problem of life that always arises. It is reminded that teaching and learning activities are held in order to provide students with learning experiences. Selection of learning models used by teachers in delivering taught material can affect learning outcomes. One model of cooperative learning is Teams Games Tournament (TGT) model. The TGT learning model is a group learning model that involves student activity with an exchange of thoughts or ideas constructing knowledge amongst students in groups when getting assigned. This research is a Classroom Action Research (PTK) or Classroom Action Research is a research that is intended to provide information on how appropriate action to improve teachers' ability and student activeness. The results of the implementation of the first cycle of action I have achieved the classical indicator that has reached 62.5% students score above 70 and the results in cycle II reach 92% students score above 70.

Abstract

This study aims to analyze and examine in depth about student’s mathematics understanding ability influenced by self-confidence. The study was designed in the form of experiment using correlational method with quantitative appoach. The population in this research is junior high school student in Cimahi and the sample as many as 28 people determined by purposive sampling technique in one of junior high school in Cimahi. The instrument in the research is the test of mathematics understanding ability as much as 5 items and the scale of student’s self-confidence as much as 36 scale statment. Based on the results and discussion, it is concluded that the students’ mathematics understanding ability influenced positively by self-confidence equal to 74,6%, whilw 25,4% influenced by factors other than student self-confidence.

Abstract

Today, there are many studies available in the literature that test the effectiveness of using augmented reality (AR). However, these studies provide varying results. In this regard, a meta-analysis is needed to examine the overall effect of all studies that question the influence of Augmented Reality-Based Learning (ARBL) on students' academic ability. Then, moderator variables need to be investigated to consider their implications. Data were examined from the Scopus and Google Scholar databases using the Publish or Perish application between 2016 and 2023. Data screening resulted in 69 independent groups of 32 eligible primary studies with 2659 subjects. Population estimation was based on a random effects model, and Comprehensive Meta-Analysis (CMA) was used as a calculation tool. The study's results provided an overall effect size of 0.81 (large effect). This shows that ARBL greatly affects students' academic ability, so its application must be considered. Of all the moderator variables analyzed, year of study, educational level differences, and subject matter were associated with differences in effect sizes in the main study. Thus, these three variables need to be considered in educational settings related to the development and implementation of ARBL in the future. Several new findings and research gaps are discussed and will help teachers, lecturers, and practitioners fill them in the future.

Abstract

This study examined the relationship between student motivation and computational thinking (CT) skills within a Scratch-based learning environment for primary school students. Utilizing a quantitative research design with a pretest-posttest framework, the research involved 28 primary school students engaged in a computational learning program centered on the Jumping Bean concept. A confusion matrix analysis was employed to assess the predictive relationship between motivation levels and improvements in CT skills. The results showed that motivation is a reliable predictor of CT gains, with high precision indicating that highly motivated students are very likely to demonstrate measurable progress. However, the recall score suggests motivation alone is not a conclusive factor, as some motivated students did not achieve the expected CT improvements. This implies that other instructional elements, such as prior knowledge, cognitive differences, teaching methods, and learning design, also significantly impact outcomes. The implications of this research suggest that educators should cultivate motivating learning environments to foster students’ CT skills effectively. Recommendations include integrating gamified elements and personalized feedback to enhance student engagement and motivation in computational learning contexts.

Abstract

This study aims to test the compatibility of structural equation (SEM) models to determine the relationship between mathematical reasoning ability and geometry problem solving ability. Using an ex-post facto research design, this study took a random sample of 100 students from a total of 296 mathematics education student population at a university in Lubuklinggau. Data were collected through mathematical reasoning tests and geometry problem-solving tests, then analyzed using the Lisrel 8.8 and SPSS programs. The results of the analysis show a very significant path coefficient, which proves that mathematical reasoning ability has a positive direct relationship with geometry problem-solving ability. This means that an increase in reasoning skills will be followed by an increase in the ability to solve geometry problems. In conclusion, this study confirms the existence of a direct relationship between the two variables, where mathematical reasoning ability contributes 15.13% to the improvement of geometry problem-solving ability. Keywords: Ability, Mathematical reasoning, Geometric Problem Solving, SEM, Lisrel
