Abstract

The results of this study showed that the implementation of the Problem-Based Learning (PBL) model could improve students’ learning outcomes. In the first cycle, the average score obtained by students was 69.44, which increased in the second cycle to 74.44. The percentage of student mastery in the first cycle was only 73.33%, with 11 out of 15 students achieving mastery, and it increased to 86.67% in the second cycle, with 13 out of 15 students meeting the mastery criteria. These findings indicate that the use of the Problem-Based Learning model is effective in enhancing students’ learning outcomes.

Abstract

The application of the Contextual Teaching and Learning (CTL) model aims to improve students’ conceptual understanding in science subjects for fifth-grade students at SD Negeri 143 Tetehaka. This research was supervised by Arna Juwairiyah, S.Pd., M.Pd. as the first supervisor and Ahmad, S.Pd., M.Pd. as the second supervisor. The study was conducted due to the following issues: (1) students’ learning outcomes were still low—many students had difficulty understanding science concepts, as shown by their average daily test scores of 50 (on a scale of 0–100), which were far below the mastery threshold of 65; and (2) the learning process was dominated by lecture-based methods, making students less interested and less involved in learning activities, which resulted in weak conceptual understanding.The purpose of this research was to determine how the implementation of the contextual learning model could enhance students’ conceptual understanding in science. This study employed a quantitative approach with the type of Classroom Action Research (CAR). The data collection techniques used were observation and tests. The results showed that in the first cycle, the percentage of students achieving mastery was 46.66% in the first meeting and 53.33% in the second meeting, with an average class score of 62.29. In the second cycle, the percentage of students achieving mastery increased to 73.33% in the first meeting and 80% in the second meeting, with an average class score of 73.43.These findings indicate that the implementation of the Contextual Teaching and Learning (CTL) model can effectively improve students’ conceptual understanding in science learning.

Abstract

This study aims to determine the improvement of students’ critical thinking skills in science learning using the Problem-Based Learning (PBL) model assisted by PowerPoint media and realia media. This research employed a quasi-experimental design. The findings revealed that there was a significant effect on students’ critical thinking skills when taught using the PBL model assisted by PowerPoint and realia media. The average N-Gain score of students’ critical thinking skills in the class that used the PBL model assisted by PowerPoint media was significantly higher (0.58) compared to the class that used the PBL model assisted by realia media (0.48). This indicates that the use of the PBL model with PowerPoint media is more effective in improving students’ critical thinking skills in science learning than the PBL model with realia media.
