Abstract

The objective of this research is to examine the implementation of the RADEC (Read, Answer, Discuss, Explain, and Create) learning model in enhancing students' critical thinking skills in social studies. A descriptive analysis was conducted to compare the pretest and posttest results between the experimental and control groups, focusing on students' critical thinking abilities. The data presented in Table 1 show that in the experimental group, the pretest score was 50.87 and the posttest score was 87.13, resulting in a difference of 36.26. In the control group, the pretest score was 50.20 and the posttest score was 85.73, yielding a difference of 35.53. These results indicate a significant improvement in the average critical thinking skills of students in both groups, with a slightly higher increase observed in the experimental group. Therefore, it can be concluded that the application of the RADEC model is effective in improving students' critical thinking skills in social studies.

Abstract

This study aims to enhance student achievement in social studies through the application of e-comic learning media. Data were collected using a learning achievement test, and both qualitative and quantitative data were analyzed descriptively. The findings indicate that the use of e-comic learning media effectively improves student learning achievement. Initial results showed an average score of 60.76, which increased to 70.51 in the first cycle and 79.74 in the second cycle. Additionally, the percentage of student learning completion improved significantly, from 30.76% at the outset to 82.05% in the first cycle, and ultimately reaching 100% in the second cycle. The study concludes that implementing e-comic learning media can significantly enhance student achievement in social studies.

Abstract

This research aims to enhance students' learning motivation through a self-efficacy approach. The study is conducted as Classroom Action Research (CAR) using the Kemmis and McTaggart model, which comprises four stages: planning, action, observation, and reflection. In this model, Kemmis and McTaggart integrate action and observation as a single unit, where observational outcomes serve as a basis for subsequent reflection. Reflections lead to modifications, actualized through further actions and observations in a continuous cycle. This research utilizes both primary and secondary data sources, with secondary data including school documents and archives. Results from the action evaluation in Cycle II indicate that 10 students (30.3%) demonstrated very high self-efficacy, while 24 students (69.7%) exhibited high self-efficacy, and no students were in the very low category. The average self-efficacy score rose from 92.29 in Cycle I to 94.91 in Cycle II, indicating a 2.62-point increase. These findings demonstrate a significant improvement in students' self-efficacy scores, reflecting enhanced learning motivation through this approach.
