Abstract

The objective of this study was to develop and assess the impact of Wizer E-LKPD on the problem-solving skills and ecological attitudes of 28 VIIC class students at SMP Negeri 1 Wita Ponda. The study employed the ADDIE model as its research framework and utilized a one-group pretest-posttest design with purposive sampling. The research instruments included validation sheets, response questionnaires completed by teachers and students, tests of problem-solving abilities, and an ecological attitude questionnaire. The findings indicated that Wizer E-LKPD was highly valid, with an average rating of 94.12%. The results demonstrated that the Wizer E-LKPD effectively enhanced problem-solving skills, achieving a medium effect size of 0.65, and improved ecological attitudes with a simple effect size of 0.30. Therefore, it can be concluded that the Wizer E-LKPD is a valid, practical, and effective tool for improving students' problem-solving abilities and fostering ecological attitudes in science learning at SMP Negeri 1 Wita Ponda.

Abstract

This study aims to develop a differentiated teaching module based on students' learning styles in the Project-Based Learning of Natural and Social Sciences (IPAS) to improve collaboration skills. The research employed a Research and Development (R&D) approach using the ADDIE model, which includes five phases: analysis, design, development, implementation, and evaluation. The subjects of the study were Grade X students at SMK Negeri 1 Parigi, with 19 students from the Akuntansi dan Keuangan Lembaga (AKL) program as the experimental class and 19 students from the Desain Pemodelan dan Informasi Bangunan (DPIB) program as the control class. Research instruments included expert validation sheets, practicality questionnaires, cognitive assessment tests (pretest and posttest), and observation sheets for collaboration skills. Validation results showed that the module achieved a validity level of 83%, categorized as valid. The module’s practicality was rated at 92% by teachers and 95% by students, both classified as highly practical. Regarding effectiveness, a comparison of posttest scores between the experimental and control groups yielded a Cohen’s d of 0.93, indicating a large effect on students’ cognitive outcomes. Additionally, within the experimental group, a comparison of pretest and posttest collaboration scores resulted in a Cohen’s d of 0.89, also classified as a large effect. These findings demonstrate that the differentiated teaching module effectively enhances students’ 21st-century skills, particularly collaboration.

Abstract

Science education in junior high school plays a crucial role in developing students' scientific thinking, particularly in understanding global issues like global warming. This study aims to assess the scientific thinking abilities of seventh-grade students at three state junior high schools in Palu City, using a descriptive approach and a test based on seven aspects of scientific thinking as defined by García-Carmona (2023). The findings reveal that approximately 80% of students showed progress in scientific thinking, with 12% achieving a competent level and 8% remaining in the beginner category. However, their understanding of scientific information from discourse and graphics averaged only 26%. Overall, students demonstrated developing scientific thinking skills, which could enhance their comprehension of scientific concepts, especially related to everyday experiences and environmental issues shared on social media. The role of teachers is essential in guiding students to understand and critically evaluate scientific information, such as articles on global warming. The study recommends developing interactive, problem-based teaching strategies to further improve students' scientific thinking skills. Future research should explore the role of media technology, teachers, and parents in supporting the development of scientific thinking regarding natural phenomena to advance science education in Palu and its surrounding areas.
