Abstract

This research aims to analyze the science process skills of junior high school students after 2 years of distance learning or post-COVID-19. The research method used is a descriptive quantitative method using multiple choice questions with 30 items and 4 answer options with 5 SPS indicators: operationalizing definitions, designing experiments, identifying and controlling variables, formulating hypotheses, and describing and interpreting data. The SPS instrument was given to 28 private junior high school students in Surabaya, 9th grade. The results obtained were that the indicator of operationalizing definitions was 33.40% with a low category, designing experiments was 38.89% with a low category, identifying and controlling variables was 40.00% with a low category, formulating hypotheses was 33.00% with a low category, and describing and interpreting data was 44.00% with a low category. The questions 2 and 4 with the indicators of recognizing and controlling variables and articulating hypotheses yielded the fewest correct answers from the students. On question 25, students with the indicator of detecting and controlling variables received the majority of the right responses.

Abstract

This study aims to develop interactive science teaching materials for elementary school students. The development of these materials is based on a constructivist learning model that emphasizes students' active engagement in the learning process. The interactive teaching materials are designed using visual and audio media, as well as practical activities such as simple experiments and simulations, to enhance students' conceptual understanding and interest in learning science. The research method used is Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The results show that these interactive teaching materials are effective in improving students' understanding of science concepts and their learning motivation. Feedback from teachers and students indicates that the materials are easy to use, engaging, and relevant to everyday life contexts. Therefore, these teaching materials can serve as an alternative to support more meaningful and enjoyable science learning in elementary schools.

Abstract

In creating educational objectives aligned with the Learning Compass 2030, it is essential to establish a learning environment where students feel comfortable and to apply learning strategies suited to the characteristics of the learners. The objective of this research is to map students' metacognitive skills to understand their learning strategies in solving science-related problems. This study employs a mixed-methods approach, which involves collecting both quantitative and qualitative data, integrating the two forms of data, and using diverse research designs. The quantitative data were obtained from administering metacognitive skills tests and questionnaires, while qualitative data were gathered from student interviews. The research yielded several findings: (1) expert validity results for the metacognitive skills instrument indicated it is valid, (2) trial testing of the instrument showed it to be reliable and valid, (3) the profile of students' metacognitive skills across all indicators was found to be low in three different schools, and (4) there was a high response rate. The novelty of this research lies in mapping students' metacognitive skills in three different regions after the COVID-19 pandemic.
