Abstract

Based on the results of initial observations at SMP Negeri 40 Medan, there are teachers who have not maximized the design, development, and utilization of learning media, especially flipbook media that has never been implemented. As well as the mathematical literacy skills and learning motivation of students are still low. This study aims to (1) produce flipbook media based on the Problem Based Learning learning model that is valid, practical and effective, (2) analyze the improvement of mathematical literacy skills and (3) analyze the improvement of student learning motivation using flipbook media based on Problem Based Learning. This study uses the ADDIE model. This study involved class VIII students of SMP Negeri 40 Medan. The instruments used in the development of flipbook media are Teaching Modules, LKPD, Mathematical Literacy Ability Tests and Student Learning Motivation Questionnaires. The results of the study are that the flipbook media meets the valid criteria with a score of 4.69, then the flipbook media was tested to obtain practical and effective media so that it meets the practical criteria with a score of 88.95, and the flipbook media meets the effective criteria with a score of 87.79. The increase in mathematical literacy skills measured by N-gain on the development trial conducted twice against pretest with posttest I with an average N-gain of 0.33 in the medium category, then against posttest I and posttest II with an average N-gain of 0.73 in the high category. Furthermore, the increase in students' learning motivation by measuring the pretest and posttest with an average N-gain of 0.6 in the medium category. Based on the N-gain results, it is stated that flipbook media based on the Problem Based Learning learning model is able to improve students' mathematical literacy skills and learning motivation at SMP Negeri 40 Medan.

Abstract

Students should be able to answer real-life math problems; therefore, mathematical problem-solving is crucial. Math problem-solving is improved by computer media. Educational media that meets students' needs motivates and inspires them, enhancing learning outcomes. Students' quantitative problem-solving skills will improve math learning results. Scratch is a computer-based learning tool that improves learning. The goal of this research is to use Scratch as a learning medium to improve students' mathematical problem-solving skills and motivation to learn mathematics. SMP Negeri 2 Kota Tebing Tinggi 7th graders completed this investigation in 2024/2025. This development research produced a valid, practical, and successful drill-and-practice-based visual learning medium to improve students' problem-solving and learning motivation. Media validity averaged 3.40, material validity 3.60, and linguistic validity 3.79. Teacher questionnaire scores averaged 3.67, while student questionnaire scores averaged 3.13 in the "Interested" category. The average learning implementation score rose to 3.25 in the second trial. Improved mathematical problem-solving and motivation were "moderate."

Abstract

This study aims to analyze the learning difficulties experienced by third-grade elementary school students in solving multiplication problems based on the Structure of the Observed Learning Outcome taxonomy. The research employed a descriptive qualitative approach involving thirty students as participants. Data were collected through written tests, observation, and interviews to identify the level of understanding and the types of difficulties encountered. The analysis technique categorized student responses into conceptual levels, namely prestructural, unistructural, multistructural, relational, and extended abstract. The results showed that the students’ average score of 2.77 out of five indicated a moderate ability level. Approximately 36.7 percent of students answered three questions correctly, while only 6.7 percent answered all correctly. Most students were found at the multistructural to relational levels, reflecting partial conceptual understanding, while only a few reached the extended abstract level, showing complete integration of ideas. These findings reveal that students still face challenges in connecting conceptual and procedural knowledge in multiplication. The study concludes that the development of conceptual thinking in multiplication occurs gradually, emphasizing the importance of learning strategies that foster integration among concepts and structured problem-solving to enhance students’ mathematical reasoning

Abstract

This research is motivated by the low mathematical problem-solving ability of elementary school students, especially when facing non-routine problems that require complex reasoning. The integration of Realistic Mathematics Education (RME) and Computational Thinking (CT) is seen as an approach capable of presenting contextual learning while stimulating systematic thinking processes. This research uses a quantitative method with a Quasi-Experimental Non-Equivalent Control Group Design involving fifth-grade students from two elementary schools in Prambon District. The experimental group received RME learning integrated with CT, while the control group received direct learning. Data were collected through pre-tests, post-tests, and self-efficacy questionnaires, then analyzed using a two-way ANOVA to examine the effect of the learning model, self-efficacy, and the interaction between the two. The results showed that the RME-CT model significantly improved mathematical problem-solving ability compared to conventional learning, with higher score increases in the experimental group. In addition, self-efficacy was shown to moderate learning effectiveness, where students with high self-efficacy achieved better results. There was a significant interaction between learning models and self-efficacy on learning outcomes. This research contributes to offering an innovative approach that combines realistic contexts and computational thinking as an effective strategy to improve elementary school students' mathematical competence and self-confidence.

Abstract

This study aims to explore the problem-solving abilities of prospective physics teachers based on multiple intelligences in the context of fluid mechanics. The research employed a survey approach by combining a problem-solving test and a multiple intelligences questionnaire to identify students’ dominant intelligence profiles. The participants were categorized into three dominant intelligence types: verbal-linguistic, logical-mathematical, and spatial. The results indicate notable differences in problem-solving characteristics among the groups. Students with verbal-linguistic intelligence tended to demonstrate higher proficiency in understanding and articulating concepts through coherent and argumentative explanations, resulting in more comprehensive verbal solutions. Students with logical-mathematical intelligence solved problems by identifying patterns and physical quantities using systematic mathematical procedures, although their solutions often lacked detailed conceptual explanations. Meanwhile, students with spatial intelligence primarily used visualization, including sketches, diagrams, or other representations, to interpret situations and derive solutions. These findings suggest that multiple intelligences influence students’ cognitive strategies for solving physics problems. The study highlights the need for instructional designs that are responsive to students’ diverse intelligence profiles to optimize the development of problem- solving skills.

Abstract

This study aims to determine the effect of using the GeoGebra application on junior high school students' understanding of mathematical concepts in the topic of Two-Variable Linear Equations Systems (SPLDV). The type of research used is a quasi-experiment with a posttest-only control group design. The population of this study is all eighth-grade students at SMP Islam Terpadu Al-Fakhri, while the sample consists of two classes selected through purposive sampling, namely class VIII-B as the experimental class receiving instruction using GeoGebra and class VIII-A as the control class with conventional teaching methods. The research instrument consisted of a written test totaling 6 questions that had been tested for validity and reliability. The research data were analyzed using a t-test with a significance level of 0.05. The research results show that there is a difference in conceptual understanding between students who learn using GeoGebra and students who learn through conventional learning. The average post-test score of the experimental class was 19.46, higher than the control class at 15.78, with standard deviations of 3.12 and 4.34, respectively. Based on these analysis results, it can be concluded that the use of GeoGebra has a positive effect on improving students' understanding of mathematical concepts in the SPLDV material.
