However, conventional teacher-centered instruction often provides limited opportunities for active participation, resulting in low cognitive learning outcomes and learning motivation. The Teams Games Tournament (TGT) cooperative learning model is designed to promote active engagement, collaboration, and healthy competition among students. This study aimed to examine the effect of the TGT cooperative learning model on eighth-grade students' cognitive learning outcomes and science learning motivation. A quasi experimental research design employing a posttest-only control group design was used. Participants were selected through purposive sampling, with one class assigned as the experimental group receiving instruction through the TGT cooperative learning model and another class serving as the control group receiving conventional instruction. Data were collected using a cognitive achievement test and a science learning motivation questionnaire. The data were analyzed using an independent-samples t-test for cognitive learning outcomes and descriptive statistics for learning motivation. The results showed that the experimental group obtained a higher mean cognitive score (60.0) than the control group (51.2). Furthermore, the independent-samples t-test indicated a statistically significant difference between the two groups (p < 0.05). The results also demonstrated an increase in students' science learning motivation following the implementation of the TGT cooperative learning model. These findings indicate that the TGT cooperative learning model has a significant positive effect on students' cognitive learning outcomes and science learning motivation.
IMPLEMENTING PROBLEM-BASED LEARNING IN EIGHTH-GRADE SCIENCE EDUCATION
Student-centered learning has become a fundamental approach in twenty-first-century education to equip learners with the competencies required to address the rapid advancement of science and technology. Among the various student-centered instructional approaches, Problem-Based Learning (PBL) has been widely recognized for promoting active engagement and meaningful learning. This study aimed to describe the implementation of the Problem-Based Learning model in eighth-grade science classrooms and to examine students' responsses to its implementation. A descriptive research design was employed involving 28 eighth-grade students and three classroom observers. Data were collected using validated observation sheets to assess the implementation of the PBL model by teachers and students, as well as a student responsse questionnaire. All research instruments were validated by three experts prior to data collection. The data were analyzed descriptively using percentage analysis. The findings revealed that the implementation of the Problem-Based Learning model reached 98%, indicating that the learning process was carried out with a very high level of implementation fidelity. In addition, students expressed positive responses toward the PBL model, suggesting that it effectively supported active participation and meaningful learning during science instruction. These findings demonstrate that Problem-Based Learning is a feasible and well-accepted instructional approach for promoting student-centered science learning at the junior high school level.
DEVELOPMENT OF SCIENCE E-MODULES FOR JUNIOR HIGH SCHOOL CLASS VII BASED ON SCIENCE TECHNOLOGY SOCIETY ON TEMPERATURE AND HEAT MATERIAL
Based on the results of the analysis that has been carried out, the data obtained shows that the teaching materials used in schools have not been able to support learning optimally. Students prefer if the teaching materials used are equipped with attractive images, use language that is easy to understand, the material presented is brief, concise, and clear, has work instructions for each activity, is equipped with videos, and practice questions. This type of research is Research and Development (R&D) with the ADDIE development model which consists of the stages of analysis, design, and development. The research instrument consists of a needs analysis questionnaire, validity test questionnaire, and practicality test questionnaire. The data obtained were analyzed using the Likert Scale formula to analyze the results of validity and practicality tests. Based on the results of the research conducted, it was found that the results of the e-module validity test by experts or lecturers were declared very valid with a percentage of 89%, the results of the practicality test by science teachers were declared very practical with a percentage of 94%, the results of the practicality test by students were in the practical category with a percentage of 79%.
