Abstract

The problem addressed in this research is students' difficulty in learning plane geometry in mathematics. The objective is to enhance students' learning outcomes using the tangram media in class IV C. This study adopts the Classroom Action Research (CAR) method, conducted over two cycles, each comprising planning, action implementation, observation, and reflection stages. The research subjects are the students of class IV C at SD Negeri 015 Tanjungpinang Timur, with a sample size of 32 students. Data collection techniques involve observation, tests, interviews, questionnaires, and documentation, analyzed through both qualitative and quantitative approaches. The results reveal that the use of tangram media for plane geometry in mathematics is successfully implemented. The mathematics KKM (Minimum Mastery Criteria) is set at 75, with a classical learning completeness threshold of 70%. The percentage of student completeness in the pre-cycle shows 11 students passing (34.3%) with an average score of 65.46. In the first cycle, there is an increase with 14 passing students (43.1%) and an average score of 71.56. The second cycle demonstrates further improvement with an average score of 76.87, and 27 passing students (84.3%). Consequently, there is an enhancement in the learning outcomes of class IV C students at SD Negeri 015 Tanjungpinang Timur through the utilization of tangram media in the subject of plane geometry in mathematics.

Abstract

This study aims to evaluate the effectiveness of the Genre-Based Approach (GBA) in improving the academic writing skills of sixth-semester PGMI students at IAI Miftahul Ulum Tanjungpinang. The research employed a pre-experimental design with a one group pretest-posttest pattern, involving 32 students as participants. Data were collected through written tests (pretest and posttest), classroom observations, questionnaires, and in-depth interviews. Quantitative data were analyzed using the Wilcoxon Sign-Rank Test with the assistance of SPSS, while qualitative data were analyzed thematically. The results show a significant improvement in students’ academic writing scores after the implementation of GBA, with the average score increasing from 66.88 (pretest) to 81.34 (posttest). The Wilcoxon Sign-Rank Test yielded an Asymp. Sig. (2-tailed) value of 0.000 (<0.05), indicating a statistically significant difference between students’ writing abilities before and after the intervention. Additionally, students demonstrated better understanding of academic text structure, increased motivation, and more frequent, use of valid references. However, some students still experienced difficulties in constructing logical arguments and initiating the writing process. These findings confirm that the Genre-Based Approach is effective in enhancing academic writing skills among PGMI students and can serve as a reference for developing writing instruction strategies in higher education
