This study aims to determine the effect of the application of the Project Based Learning model on the learning outcomes of the 8th grader at SMP Negeri 32 Padang on the digestive system and respiratory system. This type of research is a Quasi Experiment with a research design that is Nonequivalent Control Group Design. The population of the study covers all of the 8th grader at SMP Negeri 32 Padang which consists of 7 classes. The samples in this study were class VIII.6 as the control class and VIII.7 as the experimental class. The sampling technique used is Purposive Sampling. The instrument of this research is a Pre test – Post test question in the form of objective questions as many as 20 questions. The data that has been obtained is then analyzed using prerequisite tests, namely normality test and homogeneity test, then hypothesis testing is carried out. Based on the hypothesis test that has been carried out, the results of hypothesis testing calculations were obtained with the help of Microsoft excel using the t test technique with a significant level of 5%. The tcount ≥ ttable value is 2.56 ≥ 2.00, meaning that H0 is rejected and H1 is accepted. So, it can be concluded that the implementation of the Project Based Learning learning model has a significant effect on student learning outcomes at SMP Negeri 32 Padang

One of the technological innovations that can be used is WEB 3D-based learning media, which combines visual elements and text in a more real way. The following research intends to develop a WEB-Based 3D Learning Media equipped with a QR Code as a support for Solar System materials for grade VII junior high school students. This media is designed to be valid, practical, and effective in improving student understanding. The research method used is Research and Development (R&D) with a 4-D development model approach, which includes four main stages: define, design, develop, and disseminate. The research instruments include validation questionnaires, practicality questionnaires, and effectiveness questionnaires. The data obtained were analyzed using the Likert scale and the Guttman scale to assess the level of validity, practicality, and effectiveness of the developed learning media. The results of the 3D media validity test obtained a very valid category with an average score of 85%. The results of the practical test on the use of 3D media from teachers and students are in the very practical category with a teacher response questionnaire score of 93% and student responses of 94%. The effectiveness of the use of 3D media on students' learning interests is very effective with a student response questionnaire score of 91%. Thus, the following research has produced a WEB-based 3D science learning media on Solar System material for grade VII junior high school that is valid, practical, effective and ready to be disseminated.

The material of the solar system tends to be abstract so that it is difficult for students to understand, especially if it is delivered using conventional methods. The PBL model emphasizes the active involvement of students in solving real problems, while animation media helps visualize abstract concepts. This study aims to determine the effect of the Problem-Based Learning (PBL) model assisted by animation media on the learning outcomes of fifth grade elementary school students on the material of the solar system. This study used a quasi-experimental method with a Nonequivalent Control Group design. The subjects of the study consisted of two classes, namely Class V A with 25 students as an experimental class using the PBL model with animation media and Class V B with 25 students as a control class using conventional methods. Data collection was carried out through pre-test and post-test tests, observation, and documentation. The results of the t-test showed a significant difference between the learning outcomes of the two groups after treatment, with a significance value of 0.001 (p <0.05). These results indicate that the application of the PBL model assisted by animation media has a positive effect on improving student learning outcomes. This study recommends the application of innovative learning models to improve the effectiveness of science learning in elementary schools

The purpose of this article is to determine whether the effect of differentiated learning processes with the Problem Based Learning (PBL) model on students' critical thinking skills at SMP Negeri 1 Candung. The type of research used is quantitative using a quasi-experimental method with a Non-Equivalent Control Group Design. The differentiated learning process with the PBL model is applied to the experimental class while the control class uses conventional learning methods. The sampling technique is purposive sampling. The research instrument uses observation sheets, questionnaires and objective test questions. Data analysis uses normality tests, homogeneity tests and hypothesis tests. Based on the questionnaire, the implementation of differentiated learning processes with the Problem Based Learning model in the experimental class is 98.01%. The statistical analysis test in this study uses Microsoft Excel. Based on the results of the hypothesis test, the t count value is 2.240 and the t table is 2.001. So t count ≥ t table shows that there is a difference in the average between the experimental class and the control class. This means that there is a difference in the average critical thinking ability of students in the differentiated learning process with the PBL model at SMP Negeri 1 Candung. Meanwhile, students' responses to teachers in the learning process received a positive response from students of 94%.

An innovative teaching method, Game-Based Learning (GBL), has been shown to be effective in supporting teachers, particularly in Natural Science (IPA) subjects. This study examines how GBL is applied and its effects on science education in schools. To achieve this, a Systematic Literature Review (SLR) was conducted, analyzing scientific articles published from 2023 to 2025. The findings reveal that the GBL approach can significantly boost student motivation and active engagement, while also simplifying their grasp of complex and abstract science concepts. The success of GBL is highly dependent on selecting diverse and relevant learning media. Therefore, integrating GBL with suitable media presents a promising strategy for enhancing the quality of science education. Based on these implications, the study suggests that educators and educational media developers should continue to innovate by creating engaging, interactive media that aligns with science content to make the teaching and learning process more effective. It is hoped that these findings will guide teachers in choosing the right approach and help students understand science concepts in a more enjoyable manner.

The results of the Programme for International Student Assessment (PISA) show that the science literacy of students in Indonesia is still below the international average. A similar condition is also seen in the results of the Computer-Based National Assessment (ANBK) for eighth-grade students, which shows that science literacy skills have not been measured comprehensively. This study aims to determine the effect of the Read, Answer, Discuss, Explain, and Create (RADEC) learning model on the science literacy competence of eighth-grade students. This study is a quantitative study using a quasi-experimental method with a nonequivalent control group design. The research sample was determined using purposive sampling, involving one experimental class and one control class. The research instrument consisted of a 22-item multiple-choice science literacy test. Both groups were given pre-tests and post-tests to measure improvements in science literacy competence. The data were analyzed descriptively and quantitatively, with the results showing that Ha was accepted and H₀ was rejected. The t-test value showed that tcount 3.47 ≥ ttable 2.00, which was reinforced by the N-gain test results. These findings indicate a significant difference between the two groups, so it can be concluded that the application of the RADEC model has a positive effect on improving students' science literacy competency.
