The low learning outcomes of students in Biology learning at SMA Negeri 1 Tutuyan is the background for the need for learning innovations that are able to increase active participation and conceptual understanding. This study aims to analyze the effectiveness of the Group Investigation learning model in improving student learning outcomes in Cell materials. The research used a pseudo-experiment method with a one group pretest-posttest design. The research sample amounted to 35 students from class XI Science who were selected purposefully. The instruments used were multiple-choice tests, pre-tests and post-tests of 25 questions for each test. The results showed an increase in the average score from 23.14 in the pre-test to 83.14 in the post-test. Inferential data analysis using the t-test showed a t-calculated value of 89.55, far above the t-table at a significance level of 5%. The category of student learning outcomes has also undergone significant changes, from a very low majority to a high and very high majority. The application of the Group Investigation model encourages students to be active in investigation, group discussions, and independent learning, which strengthens their collective and individual mastery of the material. These findings prove that the Group Investigation model is effective in improving learning outcomes, and can be implemented as a learning strategy in the Independent Learning Curriculum. This study contributes to the development of cooperative learning models in the context of Biology learning at the high school level, and can be replicated in other materials and levels to strengthen its effectiveness.

This study aims to evaluate the implementation of the Independent Learning Curriculum at SMA Negeri 1 Sula Islands, an educational institution located in the archipelago with its own geographical characteristics and challenges. The focus of this study is to assess the effectiveness of curriculum implementation in shaping a flexible, participatory, and contextual learning experience. Using a descriptive quantitative approach, data was collected through questionnaires of school principals, vice principals for curriculum and student affairs, and grade XI science and social studies students. The results of the study showed that all respondents from school management gave an assessment of the "Very Good" category to the implementation of the Independent Curriculum. Meanwhile, students in grade XI Science gave 92% of responses in the "Very Good" category, and students in grade XI Social Studies recorded 74% in the same category, with a small percentage being in the "Poor" category. These findings indicate that the Independent Curriculum approach that emphasizes project-based learning, learning differentiation, and formative assessment has been successfully adapted effectively by teachers and students. Teacher training support, availability of facilities, and adaptation to the local context have all contributed to this success. The implications of this study show that the Independent Curriculum can be effectively implemented in the archipelago if supported by visionary school leadership and continuous training. This study makes an empirical contribution to the national education reform literature and opens further research opportunities on curriculum adaptation in the 3T region.
 

This research was conducted in class IX of Dian Todahe Middle School for the 2021/2022 academic year, with 25 students as subjects. This research aims to improve student learning outcomes by applying the Problem-Based Learning (PBL) approach to learning the movement of living creatures. This particular form of research is included in classroom action research (CAR) classification. This research examines student learning outcomes by analyzing their test scores before and after their involvement in the learning process, with a particular focus on Biology education, which is related to the movement of living things. Research findings show an increase in student performance during cycle II, which is then accompanied by an increase in student engagement. Of the total number of students, 22 (88%) completed their studies by getting a maximum score of 65. On the other hand, three students (12%) could only complete their studies if they scored below 65. The learning outcomes achieved in cycle II have fulfilled the requirements for completion. Traditionally, there has been a visible improvement in students' understanding of the subject matter.
