This research is a quantitative research using quasi-experimental design. Before receiving treatment, the experimental group and the control group were given a pre-test to evaluate students' science literacy. The location of the research was carried out on Jalan Lintas Riau, class IV SDN 0401, Pasar Ujung Batu Village, Sosa District, Padang Lawas Regency, North Sumatra Province. The research time was carried out in the odd semester in July-October 2024/2025. The sample of this study used 25 students, namely the experimental and control classes. The data collection technique for this study used tests and interviews. Based on the results of the study, the increase in students' science literacy skills was also strengthened by empirical findings in this study, where the average post-test score in the experimental class reached 80.16, much higher than the control class which only reached 73.20. In addition, the results of the t-test showed a very small significance value (p = 0.000056), indicating that the difference in learning outcomes between the two classes was not a coincidence, but a real result of the application of the CTL model. The fact that the experimental class showed lower variance in the posttest also indicates that the CTL model is able to balance achievement between students and reduce academic gaps.

This research analyzes teacher performance in developing Integrated Social Sciences teaching materials at SMPN 7 Medan. The research method used is a qualitative descriptive method. The interview results show that teachers are able to organize teaching material by combining various fields of study, such as Geography, Economics, History and Sociology, by agreeing on a theme first before presenting it to students. The development of Geography teaching materials, which is considered more difficult than other fields of study, is carried out with a longer time allocation and the use of local resources. In teaching methods, teachers apply fun approaches such as discussion, Contextual Teaching Learning (CTL), Quantum Teaching, and inquiry to increase student involvement and encourage critical thinking. However, obstacles in developing teaching materials, especially Geography material, are overcome by enriching literacy and utilizing learning methods based on group discussions and case studies. Integrated social studies learning at SMPN 7 Medan becomes more effective and relevant to students' daily lives thanks to the contextual approach applied by the teacher.

This research is a type of classroom action research (PTK) which uses a qualitative approach. The CTL (Contextual Teaching and Learning) approach is the approach used in this research. The research subjects were students in class VII-2 of Beringin 1 State Junior High School in the 2023/2024 academic year, consisting of 32 students, namely 13 boys and 19 girls. Data collection techniques include objective tests, observation, direct question and answer, documentation, and field notes. The instruments used include learning outcomes tests, assessment of students' attitudes and emotions, assessment of writing skills based on assignments, as well as observation sheets from the research process. The results of reflection and data analysis during cycles I and II of the learning process show that the implementation of CTL has gone well. Students are very involved in learning activities and most have completed assignments. The indicators for implementing learning using the CTL method in cycle II entered the very good category or 90.
