Abstract

This classroom action research aimed to improve students’ learning interest, participation, and achievement in biology through the application of Culturally Responsive Problem-Based Learning (CRPBL) supported by flipped classroom strategies. The study was conducted in two cycles with 32 students from class XI at SMA Negeri 7 Palu. Data were collected using questionnaires, observation sheets, and achievement tests, and analyzed through percentages, mastery, and N-Gain. The findings indicate substantial improvements across all dimensions. Students’ interest rose from 62.5% (moderate) in Cycle I to 85.3% (high) in Cycle II, while participation increased from 38% (low) to 81% (high). Academic achievement also improved, with mean scores rising from 80.0 to 86.2 and mastery from 76% to 91%. The N-Gain of 0.48 reflected medium improvement. These results provide strong evidence that CRPBL with flipped classroom strategies can effectively enhance students’ engagement and performance in biology. Beyond its effectiveness, this study addresses the scarcity of empirical research integrating culturally responsive teaching, problem-based learning, and flipped classroom approaches in Indonesian secondary schools, thereby filling a critical gap in contextualized biology education. The findings imply that teachers can adopt CRPBL to design more meaningful lessons, while schools may implement it to align with the Merdeka Curriculum. Future studies are recommended to apply CRPBL in varied contexts with longer durations to further validate its effectiveness.

Abstract

This study aimed to enhance students’ learning outcomes through the application of the Team Games Tournament (TGT) cooperative learning model. The research followed a Classroom Action Research (CAR) design and was carried out in two cycles, each consisting of four stages: planning, implementation, observation, and reflection. The participants were 36 Grade XI Science 5 students at SMAN 1 Palu during the even semester of the 2024/2025 academic year. Learning outcomes were evaluated using the class average scores from the final evaluation sheets, supported by the percentage of students who achieved mastery learning. Data were collected through Google Forms and analyzed using a five-point Criterion-Referenced Assessment (CRA) scale. The findings revealed an improvement in learning achievement from Cycle I to Cycle II. In Cycle I, the average student score was 73.87, categorized as moderate, whereas in Cycle II it increased to 85.21, categorized as high. Additionally, the mastery learning percentage rose from 45% in Cycle I to 71.3% in Cycle II. These results indicate that the implementation of the TGT cooperative learning model effectively enhances students’ learning outcomes in Biology.
