Pengembangan Perangkat Pembelajaran Fisika Berbasis Investigative Science Learning Environment (ISLE) Untuk Meningkatkan kemampuan Berpikir Kritis

Abstract

This study aims to obtain student worksheets based on the investigative science learning environment (ISLE) to improve students' critical thinking skills. The research model used in this study refers to the ADDIE development model, namely: 1) Analysis, 2) Design, 3) Development, 4) Implementation and 5) Evaluation. The feasibility of LKPD was measured by the results of LKPD validation and the questionnaire responses given to the subject were 3 teachers. The overall results of LKPD validation show an average score of 4 that falls into the agreed category. This research uses quantitative and qualitative approaches. The research design used in this research is research and development (commonly referred to as R&D). The subjects of this study were physics teachers at SMA Negeri 8 Banda Aceh, totaling 3 people. The research data were obtained through questionnaire responses and interviews that were distributed to each teacher. Data processing was carried out through statistical analysis using a Likert scale. The results showed that the overall average results of the teacher's response questionnaire, it is known that the overall subject response was agreed. From both measurements it was found that LKPD based on investigative science learning environment (ISLE) can improve students' critical thinking skills.
