Abstract

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.

Abstract

This research aims to produce a mobile learning media product using an articulate storyline application on human circulatory system material that is feasible and can be used by students at SMA Negeri 1 Amurang. Mobile learning media using the articulate storyline application is needed by school teachers to help during the learning process. This type of research is Research and Development / R&D development research using the ADDIE model. This model, as the name suggests, is Analysis, Design, Development, Implementation and Evaluation. The test instrument in this research is the product validity results from material and media experts. The data analysis techniques used are qualitative and quantitative approaches. The results of this research: 1) Development of mobile learning media using the articulate storyline application on the circulatory system material. 2) The quality of mobile learning aids on human circulatory system material is excellent. The assessment results from learning material experts obtained a feasibility percentage score of 85% for the very valid category. The assessment results from learning media experts obtained a feasibility percentage score of 89.9% for the very valid category. The response of students in class XI MIPA was in the perfect/exciting criteria with a percentage of 87.5%. It was concluded that the mobile learning media using the articulate storyline application on the circulatory system material at SMA Negeri 1 Amurang is very suitable to be used as a source of teaching material in the learning process.

Abstract

This research uses a quasi-experimental method with a pretest and post-test control group design research design. This research uses the Numbered Head Together Cooperative Learning model to improve student learning outcomes at SMA Negeri 2 Tondano for the 2022/20223 academic year. The sample in this study was class. The average post-test score obtained in the experimental class was 87.7, and the average in the control class was 78.1. The data analysis technique used is the t-test with the condition that the data comes from a normally distributed and homogeneous population—test normality using the Lililefors test and homogeneity. Based on the hypothesis of the research statistical data, a tcount of 2,730 was obtained. Based on the ttable with α=0.005 and degrees of freedom (dk) = n1 + n2 -2 =20+20-2= 38, By looking at the ttable, we get ttable = 1.688. So tcount is greater than ttable, namely tcount = 2,730 > ttable = 1,688. Thus, according to the test criteria, if tcount > ttable, then H0 is rejected, so hypothesis H1 is accepted, and it is concluded that there is an influence of using the Numbered Head Together model on student learning outcomes in the human respiratory system material at SMA Negeri 2 Tondano.

Abstract

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.
