Abstract

One of the most important skills in mathematics is mathematical representation, which is the ability to develop and represent mathematical concepts in symbols. However, most students have difficulties in developing mathematical ideas in this form. This research aims to improve students"™ mathematical representation ability by using the jigsaw learning model and the student facilitator and explaining learning model. The two learning models are compared to see which is more effective in increasing students"™ mathematical representation skills. This research is a quasi-experimental method performed at a senior high school in Deli Serdang Regency, North Sumatra Province. A random sampling technique was used and two groups were compared, with the experimental group-1 treated with the jigsaw learning model and the experimental group-2 with the student facilitator and explaining learning model. Data collection techniques include interviews, observation, and tests as the instruments. An Independent t-test sample was used in data processing and analysis. The research findings identified that the students of the jigsaw learning model have a significantly higher mathematical representation ability compared to those of the facilitator and explaining learning model. Based on this finding, it is concluded that the jigsaw learning model is more effective in developing and representing mathematical ideas in symbols.

Abstract

This study aims to determine the differences in the reasoning abilities and mathematical representation abilities of students who are taught using Jigsaw learning and Student Facilitator and Explaining learning in class X SMA PAB 6 Helvetia TP. 2019-2020.This research is a type of quantitative research with a quasi-experimental type of research. The population is all students of class X SMA PAB 6 Helvetia TP. 2019-2020. The samples in this study were class X MIA-1 and class X MIA-2. The data analysis technique used normality test, homogeneity test and hypothesis test using analysis of variance (ANAVA). These findings show: 1)The reasoning ability and mathematical representation ability of students taught by Jigsaw learning are better than students taught by Student Facilitator and Explaining learning, 2)Mathematical reasoning abilities of students taught by Jigsaw learning are not better than students taught by by learning Student Facilitator and Explaining, 3)The ability of mathematical representation of students who are taught by learning Jigsaw is better than students taught by learning of Student Facilitator and Explaining, 4)There is no significant interaction between the learning model used on reasoning ability and mathematical representation ability student.The conclusion of this study explains that the reasoning ability and mathematical representation ability of students taught by Jigsaw learning are better than students taught by Student Facilitator and Explaining learning in class X SMA PAB 6 Helvetia TP. 2019-2020.

Abstract

Objective: This study aims to describe the process of developing educational multimedia, specifically the “Zuma Function” game, using Scratch programming for mathematics learning on the topic of relations and functions. Methods: The research employed a Research and Development (R&D) approach, following the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The study involved 35 mathematics education students from a university in West Java and 6 eighth-grade students from a junior high school in Bandung, Indonesia. Data were collected using various instruments, including questionnaires, tests, interviews, and documentation. Findings: The developed learning media was evaluated by experts, receiving a material expert test score of 81%, and a learning media expert test score of 83%, both categorized as feasible. The functionality test, measured through User Acceptance Testing, yielded an average score of 85.1%, indicating a very feasible category, while the effectiveness test showed a 30.5% improvement in students’ conceptual understanding, with scores rising from 64.83 to 95.33. Conclusion: Based on the study’s findings, the Scratch-based multimedia for teaching relations and functions in mathematics was successfully developed using the ADDIE model. Positive user feedback and significant improvements in student test scores suggest that this multimedia is effective in enhancing students’ understanding of the concept, though there are areas that could be further refined.        Keywords: learning media, mathematics game, function, Scratch, ADDIE.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1410-1427
