Abstract

This study aims to develop a problem-based science practicum guide intended for grade VIII junior high school students in the first semester. The problem-based approach was chosen because it has proven effective in enhancing students' critical thinking and problem-solving skills. This research employed the 4D method, encompassing the stages of Define, Design, Develop, and Disseminate. The findings indicate that the problem-based practicum guide developed meets the criteria for validity, practicality, and effectiveness. The validity score reached 4.2, indicating it meets the valid criteria, while the practicality score reached 4.6, classifying it as practical. Additionally, the guide’s effectiveness is demonstrated by a positive student response rate of 84.8%. The final product from this research is expected to serve as a reference for teachers in conducting problem-based science learning, thereby supporting improvements in the quality of science education in schools.

Abstract

This study aims to analyze the effect of Inquiry-based learning model on retention of low-ability students, as well as explore the interaction between learning model and academic ability. Using an experimental design with 2-Way ANOVA technique, this study involved 60 students who were divided into four groups based on academic ability and learning model. The analysis showed that the Inquiry model had a significant effect on the retention of students with low academic ability (p = 0.001), while academic ability itself had no significant effect (p = 0.164). The interaction between learning model and academic ability also showed no significant effect (p = 0.742). LSD test results revealed that the Inquiry - Low group had a higher retention rate compared to the Conventional - Low group. This finding supports the theory of constructivism and provides practical implications for educators to implement more active and participatory learning models for students with low academic ability. Although this study has limitations related to sample size and measurement duration, the results open up opportunities for further research that considers other factors that may affect student retention, such as motivation and social support. Overall, this study contributes to the development of more inclusive and effective learning theories and educational practices.

Abstract

This study aims to analyze the effectiveness of problem-based laboratory guides in enhancing students’ active participation in science learning. The research employed a Posttest-Only Control Group Design involving a sample of 30 students. Data were collected through an observation sheet encompassing four dimensions of active participation: cognitive process, behavioral action, social collaboration, and affective motivation. The results of the Paired Samples t-Test indicated that the Sig. (p) value for all variables was less than 0.05, signifying a significant difference between the control and experimental classes. The overall mean score of students’ active participation increased from 2.01 (moderate category) in the control class to 3.88 (high category) in the experimental class, with the greatest improvement observed in the cognitive dimension. These findings demonstrate that the implementation of problem-based laboratory guides is effective in fostering students’ active engagement, strengthening collaboration, and enhancing learning motivation in science laboratory activities
