Abstract

The low level of students’ conceptual understanding of the solar system remains a pressing issue in science education, largely due to the dominance of lecture-based instruction and the limited use of concrete, interactive learning media. This study aims to develop the eco edukit SITASUR (sistem tata surya), an environmentally friendly learning medium based on the SAVI (somatic, auditory, visual, intellectual) approach, to enhance students’ comprehension of solar system concepts. Using the research and development (R&D) method with the ADDIE model, the product was validated by subject matter and media experts, yielding high feasibility scores of 87.36% and 81.31%, respectively. An effectiveness test, employing a one-group pretest–posttest design, demonstrated a significant improvement in learning outcomes, with average scores rising from 42.50 (pretest) to 81.23 (posttest). The resulting N-Gain score of 0.64 (moderate category) indicates that the eco edukit SITASUR is effective and suitable for junior high school science education. Beyond improving conceptual understanding, the media also fosters students’ environmental awareness

Abstract

This research is based on the limited use of learning media which results in students experiencing difficulties in understanding lessons and a lack of learning motivation, which impacts low learning outcomes. This research aims to develop valid, effective, and practical google sites multimedia to improve conceptual understanding and student motivation in the material of the digestive system. The research method used was research and development (R&D) with the ADDIE model, namely: analyze, design, development, implementation, evaluation. Data were collected through observation, interviews, and questionnaires. Validation by material experts showed a "very valid" category with a percentage of 87.74%, while media experts reached 90.22%. The effectiveness test produced a significance of 0.000 (<0.05), indicating a significant difference between the pretest (63.28) and posttest (89.62) scores, with an average increase in N-Gain of 0.72 (high). The learning motivation questionnaire obtained a score of 88.77% (very high). The practicality test by teachers produced 99.10% and and user responses from students 92.07%, indicating this application is very practical. The research results prove that google sites is feasible, effective, and practical to use to improve students' conceptual understanding and motivation in the digestive system topic.

Abstract

Environmental literacy is one of the important skills of the 21st century that needs to be developed along with increasingly complex global environmental changes, especially related to the issue of plastic waste which is a real problem in the school environment. However, learning at one of the junior high schools in Tulungagung is not optimal in fostering environmental awareness and the media used is not varied enough. The purpose of this study is to produce a PBL-based e-comic that is feasible, practical, and effective in improving students' environmental literacy on the material of human influence on the ecosystem. This study uses the ADDIE development model. The results of the media validity test of 89.79% and material of 90.00% were classified as very valid, and the assessment instruments used were valid and reliable. The practicality test by teachers and students obtained a percentage of 91.30% classified as very practical. The effectiveness test showed that there was an increase in environmental literacy between before the application of media (pretest) and after the application of media (posttest) with an average n-gain value of all environmental literacy indicators of 0.33 including the moderate category. The findings of this study indicate that e-comic based on Problem Based Learning are feasible to use, practical, and able to improve students' environmental literacy
