Abstract

This research aims to create a clean and beautiful environment in Hutanamora Village through gotong royong activities, which increase the value of togetherness and care for the environment. The research used a participatory approach that actively involved the village community in the planning, implementation and evaluation of events. Environmental cleaning, waste management, and greening of the village's strategic areas were the focus of the gotong royong program. The results showed that gotong royong not only improved the cleanliness and beauty of the environment but also increased the sense of unity and cooperation among residents. In addition, the community is increasingly aware of the importance of protecting the environment. So, gotong royong is a great solution to make the environment clean and beautiful. It also builds the character of a community that cares and is responsible for environmental sustainability.

Abstract

This study aims to determine the effect of the Make A Match learning model assisted by Wordwall media on the critical thinking skills of fifth-grade students in mathematics at SD Negeri 104217 Sidomulyo for the 2024/2025 academic year. The research method used is an experimental method with a quantitative research approach. To collect data, the instruments used were 5 essay test questions and a 30-item questionnaire. The sample consisted of 32 students, selected using total sampling technique. To assess students’ initial abilities, a pretest was conducted with an average score of 28, which falls into the "poor" category. The results showed an improvement in the posttest scores, with an average score of 83, classified as "very good." It can be concluded that the students’ learning outcomes improved significantly with the implementation of the Make A Match learning model assisted by Wordwall media. This was supported by the correlation coefficient test result of 0.764 ≥ 0.349, indicating a strong correlation. Furthermore, the hypothesis test yielded a t-count value of 6.492, while the t-table value was 1.694. Since 6.492 ≥ 1.694, the alternative hypothesis (Ha) is accepted and the null hypothesis (Ho) is rejected. Based on the t-test, it can be concluded that there is a significant positive effect of the Make A Match learning model assisted by Wordwall media (X) on students’ critical thinking skills (Y).

Abstract

This study was conducted to improve the problem-solving skills of class VIII-2 students of SMPN 9 Medan in mathematics learning with the topic of Investigating the Properties of Geometric Figures. Learning was carried out using Live Worksheet as a learning media with the Problem Based Learning (PBL) as method. The object of this study was to improve problem-solving skills in learning to Investigate the Properties of Geometric Figures in class VIII-2 students of SMPN 9 Medan in the 20024/2025 academic year. This study used the Classroom Action Research (CAR) method which focused on Cycle I and Cycle II. In this study, the instruments used were teacher observation and tests (pre-test, post-test I and post-test II). Based on the data that has been analyzed, it was obtained that students' problem-solving skills increased from cycle I to cycle II with an N-Gain index of 0.56 with the category "Medium". Therefore, the researcher concluded that the application of Problem Based Learning using Live Worksheet can improve problem-solving ability in learning to Investigate the Properties of Geometric Figures in class VIII-2 students of SMPN 9 Medan.

Abstract

This study aims to enhance the problem-solving abilities of seventh-grade students (Class VII-6) at SMPN 9 Medan during the 2024/2025 academic year, specifically in their understanding of circle geometry. To achieve this, the (PBL approach was implemented as part of a Classroom Action Research (CAR) design, which was carried out in two cycles: Cycle I and Cycle II.To assess students' progress, the study used pre-tests, post-tests for Cycle I, and post-tests for Cycle II as evaluation tools. The collected data was analyzed using descriptive statistics, allowing for a comparison of students' problem-solving abilities over time. The results indicate a consistent improvement in students' individual and class-wide problem-solving performance between Cycle I and Cycle II. Based on these findings, the study concludes that Problem-Based Learning (PBL) effectively enhances students' ability to solve mathematical problems, particularly in the context of circle geometry, among seventh-grade students at SMPN 9 Medan

Abstract

This research aims to improve students' mathematical problem-solving skills through the Problem-Based Learning (PBL) model integrated with a Culturally Responsive Teaching (CRT) approach. This study is a classroom action research with subjects from the 8th grade class VIII-3 of SMP Negeri 9 Medan for the 2024/2025 academic year. The results show an improvement in mathematical problem-solving skills: the indicator of performing problem-solving increased from 68.75 to 81.77. Additionally, the indicator of reviewing also showed an increase from 44.53 to 77.34. Overall, the average mathematical problem-solving ability of the students improved from 68.75 to 84.18, with a classical completeness of 93.75%. The N-gain achieved in cycle I was 0.49, which falls into the moderate category. Since the test results for students' problem-solving abilities and the teacher's activity results met the success indicators, the actions were not continued and were stopped at cycle II.
