Abstract

Fractions are one of the mathematics materials at the elementary school level. Mathematics is still a difficult subject for students, especially in fraction addition operations. Therefore, some parents choose to bring in private teachers to help their children understand mathematics. This service is a learning assistance for students in Jeneponto district, South Sulawesi, which aims to train students to complete fraction addition operations through the media of fraction cards. This service was carried out by several lecturers of Mathematics Education at the Faculty of Tarbiyah and Teacher Training at UIN Alauddin Makassar for 7 meetings, by making fraction card media to help students understand the concept of fractions, especially in fraction addition operations. The results of this dedication show that after participating in this community service activity, students can complete the operation of adding fractions. Another finding from this service is that there are still students who have not mastered the multiplication and division operations of integers, resulting in difficulties in completing fraction addition operations.

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

Penelitian ini bertujuan untuk mengevaluasi penggunaan bahan ajar software matematika "Matlab" dalam meningkatkan keterampilan matematika mahasiswa pendidikan matematika di UIN Alauddin Makassar. Penelitian ini menggunakan pendekatan kuantitatif dengan desain one group pretest-posttest. Sampel penelitian adalah mahasiswa semester 4 kelas B sebanyak 22 orang. Instrumen yang digunakan terdiri dari lembar observasi, lembar tes, dan lembar angket respon mahasiswa. Data diolah menggunakan uji N-Gain dan paired sample t-test. Hasil penelitian menunjukkan bahwa penggunaan bahan ajar software Matlab cukup efektif dalam meningkatkan keterampilan matematika mahasiswa. Namun, perlu diperhatikan bahwa penggunaan software matematika hanya efektif jika didukung oleh pendekatan pembelajaran yang tepat dan terintegrasi dengan baik dalam kurikulum matematika.

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.

Abstract

This study aims to develop and assess the quality of an ethnomathematics-based mathematical problem-solving test instrument adapted from the traditional Maggale-Majjekka game and the architecture of the Syekh Yusuf Gowa Grand Mosque. This study used a quantitative descriptive method involving 17 ninth-grade students as subjects. The instrument consisted of 10 descriptive questions at cognitive levels C4-C6 and was assessed using Polya’s four-step rubric. The analysis of the instrument’s quality included item validity, reliability, difficulty level, and discriminating power. The results showed that nine items were valid, while one item was invalid. The Cronbach’s Alpha reliability value of 0.831 indicates excellent internal consistency. The difficulty level analysis shows that one item is classified as easy, two items are moderate, and seven items are difficult. The discriminating power shows that seven items are in the fair category, while three items are in the poor category. These findings indicate that the instrument is suitable for measuring problem-solving skills in a local cultural context and contributes to the development of standardised ethnomathematics-based assessments. Further research could expand the trial to a larger sample and refine items with low discriminating power. The study concludes that the developed ethnomathematics-based problem-solving test instrument demonstrates satisfactory psychometric properties and is appropriate for assessing students’ higher-order mathematical thinking within a cultural context. This research contributes by providing an initial model for integrating local cultural elements into standardized mathematical assessment, as well as offering empirical evidence that ethnomathematics-based instruments can achieve both contextual relevance and measurement validity.
