Abstract

This study analyzes errors made by eighth-grade students in solving problems involving three-dimensional geometric shapes with flat surfaces and examines the factors causing these errors. Using a qualitative descriptive approach, three students with varying error levels (high, medium, low) were selected for analysis through written tests and in-depth interviews. Data were processed using the Miles and Huberman model: data reduction, data presentation, and conclusion drawing. Findings identified four main error types: factual, conceptual, principle, and operational. High-error students mainly struggled with conceptual understanding and operations, while low-error students primarily made operational errors. The results highlight that weak conceptual understanding and cognitive overload were the key factors in these errors. This study implies that teaching strategies should enhance both conceptual and procedural knowledge, utilizing interactive and manipulative learning methods to reduce cognitive load and improve student performance in geometry.

Abstract

Analogical reasoning plays a vital role in mathematics learning, especially in helping students solve new problems by using structural similarities with known problems. Each student has a different thinking style, which influences how they process information to solve mathematical problems. This research aims to analyze the analogical reasoning thinking process in solving mathematical problems from the perspective of Sternberg's thinking styles. The study employs a qualitative approach with exploratory methods. This study involved 9th-grade students from a public junior high school in Tasikmalaya City, West Java. The results conclude that the complete and accurate analogical reasoning thinking process in solving mathematical problems is exhibited by the legislative, executive, judicial, local, and internal thinking styles.

Abstract

This research is a classroom action research that pays attention to learning styles, namely visual, auditory, and kinesthetic learning styles. This study aimed to determine the implementation of differentiated learning assisted by Canva and Quipper media to improve learning outcomes of class XI IPA 4 in trigonometry material so that the improvement can be known. This classroom action research was carried out in September-October 2023 with two cycles. In cycle I, differentiated learning was carried out with 75% student activity. The test results in cycle I showed completeness of 58.62%, with an average of 80.82. Because it has not met the benchmark for success, an increase is needed in cycle II with changes in strategies in the kinesthetic group and visual group from cycle I. In cycle II, differentiated learning was carried out with 87.5% student activity. The test results in cycle II increased with a completeness percentage of 88.23%, with an average of 89.67. The results of cycle II have met the criteria for class learning completion so the application of differentiated learning on trigonometry material in class XI IPA 4 is said to be successful. Differentiated learning assisted by Canva and Quipper can be one of the learning strategies chosen

Abstract

This study aims to determine the improvement in students' mathematical communication skills in learning geometric number patterns through the Group Investigation model with the Peer Teaching method. The study uses an experimental method. The population in this study includes all 8th-grade students in the middle school. The sample consists of all students in classes VIII-G and VIII-I. The research instrument used to collect data is a test on mathematical communication skills specifically designed for geometric number patterns. Based on the data obtained, it can be concluded that the experimental class performed better than the control class. In the experimental class, there were 4 students with low ability, 16 students with moderate ability, and 14 students with high ability. Meanwhile, in the control class, there were 7 students with low ability, 24 students with moderate ability, and 3 students with high ability.

Abstract

This study aims to describe students' self-regulated learning in mathematics learning supported by Edmodo-GeoGebra on the topic of the volume of rotating objects. The research employs a qualitative approach with a descriptive method. The participants in this study were 36 students from Universitas Bina Bangsa. The data collection technique involved distributing a self-regulated learning questionnaire consisting of 30 statements with 8 indicators. Data analysis was conducted by calculating the percentage of students' responses, which were then described using percentage interpretation criteria. The analysis results for each indicator of self-regulated learning are as follows: 1) learning initiative 76%; 2) diagnosing learning needs 78%; 3) setting learning goals 76%; 4) viewing difficulties as challenges 75%; 5) utilizing and seeking relevant resources 74%; 6) selecting and applying learning strategies 77%; 7) evaluating the learning process and outcomes 76%; 8) self-concept 74%. The overall average of students' self-regulated learning supported by Edmodo-GeoGebra was 75.57%, categorized as high. This study recommends that educational institutions support and optimize the improvement of students' self-regulated learning.

Abstract

Students face challenges in understanding the minimum competency assessment (AKM) mathematical literacy questions, as they struggle to interpret and solve the problems effectively. This difficulty stems from their low comprehension of the questions and limited problem-solving skills, particularly when confronted with questions differing from the examples provided by the teacher. This study investigates students’ abilities to solve AKM mathematical literacy questions using Polya’s problem-solving steps. The research is descriptive with a qualitative approach, involving a population of all Grade VIII students at SMP 21 Bengkulu City during the 2023/2024 academic year. The sample consisted of 30 students from class VIII.3 and 30 from class VIII.6. Data collection included test and non-test (interview) methods, utilizing AKM-based test instruments and Polya step-guided problem-solving tasks. Results indicated that 44 students (73.33%) demonstrated low ability, 11 students (18.33%) showed medium ability, and only 5 students (8.33%) exhibited high ability in solving AKM literacy questions. Overall, students’ problem-solving skills were categorized as low, with notable difficulties in planning, executing, and reviewing solutions to mathematical problems.
