Abstract

The increasing implementation of distance learning has highlighted the need for accessible and effective digital learning media that support students' independent learning. However, many students continue to experience difficulties due to limited internet access and challenges in understanding learning materials during online instruction. This study aimed to develop an Android-based science learning application on the topic of temperature and heat for seventh-grade junior high school students and to evaluate its validity and practicality. The study employed a Research and Development (R&D) approach using the Four-D (4D) model, consisting of the Define, Design, and Develop stages, while the Disseminate stage was not conducted. Data were collected using validity and practicality questionnaires. The developed application was evaluated by expert validators, teachers, and students. The results showed that the application achieved a validity score of 91.67%, categorized as very valid. In addition, the practicality scores were 83.75% from teachers and 86.75% from students, both classified as very practical. These findings indicate that the Android-based science learning application is a valid and practical instructional medium for supporting distance learning and facilitating independent learning on the topic of temperature and heat among junior high school students.

Abstract

Learning in the 21st century requires students to be actively involved in learning activities. The 2013 curriculum also requires students to be actively involved during teaching and learning activities while the teacher acts as a facilitator. The 2013 curriculum also requires teachers to develop learning that integrates 4 important things, one of which is 21st century skills (4C skills). The character of the 4C skills is student centered (student centered learning), where students are required to be active in finding learning resources that can meet their learning needs. This study aims to determine the effect of the jigsaw cooperative model on the cognitive learning outcomes of class VIII students of SMPN 40 Padang. This research is a quasi-experimental research with a posttest only control group design. The results showed that the posttest average of the experimental class was 62.5 and that of the control class was 55.78. So it can be concluded that there is a significant influence of the jigsaw cooperative learning model on the cognitive learning outcomes of class VIII students of SMPN 40 Padang.

Abstract

Students' learning outcomes in science remain a major concern due to the limited effectiveness of conventional instructional approaches in fostering meaningful learning. Preliminary observations at SMPN 1 Nan Sabaris indicated that students' science learning outcomes were relatively low, highlighting the need for more innovative and student-centered learning models. This study aimed to examine the effect of the POE2WE (Prediction, Observation, Explanation, Elaboration, Write, and Evaluation) learning model assisted by Student Worksheets on students' science learning outcomes. A quasi-experimental research design employing a posttest only control group design was used. The participants were selected through purposive sampling, with one class assigned as the experimental group receiving instruction using the POE2WE learning model assisted by Student Worksheets, while another class served as the control group receiving conventional instruction. Data were collected using two assessment instruments: a 25-item multiple-choice test to measure students' cognitive learning outcomes and a performance assessment rubric to evaluate psychomotor skills. The data were analyzed using an independent-samples t-test. The findings revealed that the experimental group achieved significantly higher cognitive and psychomotor learning outcomes than the control group. These results indicate that the implementation of the POE2WE learning model assisted by Student Worksheets (LKPD) has a significant positive effect on students'science learning outcomes. Therefore, the POE2WE learning model can be considered an effective instructional approach for improving students' learning outcomes in science education.
