Abstract

This research aims to determine the effect of the Problem-Based Learning (PBL) model with the Realistic Mathematics Education (RME) approach on students' mathematical communication skills. This research approach uses a quantitative approach with an experimental research type, a quasi-experimental type with a pretest-posttest control design. The population in this study was 107 MTs Guppi Buntu Barana students. The research sample consisted of 36 students. The sampling technique uses Cluster Random Sampling. Tests and observations were carried out for data collection. The research instruments used in this research were mathematical communication ability test questions and observation sheets. Data analysis techniques use descriptive statistical analysis and inferential statistical analysis. The results of this research show that the average mathematical communication ability of students in classes that do not use the PBL model with the RME approach from pretest to post-test increased from 34.50 to 81.56, with an increase of 47.06. The mathematical communication skills of students in classes that use the PBL model with the RME approach obtained an average score from pretest to posttest that increased from 40.39 to 89.72, with an increase of 49.33. So, the PBL model with the RME approach has a significant influence on students' mathematical communication skills.

Abstract

This research aims to develop animation-based learning media on students' mathematical literacy abilities at MAN Bantaeng and evaluate its validity, practicality, and effectiveness. This research uses the ADDIE model consisting of analysis, design, development, implementation, and evaluation. Research instruments include validation sheets, student and teacher response questionnaires, student activity observation sheets, teacher ability observation sheets in managing learning, and mathematical literacy tests. The test subjects were 21 students. The validity of this media is in the very valid category. Practicality was assessed as very positive, with teacher responses reaching 86.11% and the teacher's ability to manage learning reaching 4.51 in the very high category. The results of the effectiveness analysis are included in the very positive category, with student responses reaching 86%, student activity during learning reaching 60% in the good category, and the level of completion of the mathematics literacy test reaching 66.67%. Thus, animation-based learning media can be used in learning because it meets the validity, practicality, and effectiveness criteria.

Abstract

Mathematics learning on solid geometry is often considered difficult due to the limited media used, therefore more interactive media are needed. This study aimed to develop an interactive learning media assisted by Edpuzzle that is valid, practical, and effective. The type of research is Research and Development (R&D) using the 4D model (Define, Design, Develop, Disseminate). The research instruments included validation sheets, teacher and student response questionnaires, student activity observation sheets, learning implementation sheets, and learning achievement tests. The subjects were 23 seventh grade students of MTs Sultan Hasanuddin. The results showed that the developed media had a validity level of 95% (very valid). Practicality was indicated by teacher responses of 85% (very good) and the implementation of learning in the 'implemented' category. Effectiveness was shown by student activities of 90% (very active), student responses of 87.36% (very good), and 86.96% of students achieving the minimum mastery criteria with an N-Gain of 0.54 (moderate improvement). Therefore, the interactive learning media assisted by Edpuzzle was declared valid, practical, and effective to be used in mathematics learning on solid geometry.
