Development of ICARE-Based Physics Teaching Materials to Improve Students' Critical Thinking Ability

Abstract

Research on the development of ICARE-based teaching materials aims to: 1) analyze the results of the content validity of ICARE-based physics teaching materials which meet valid criteria, 2) analyze practitioners' assessments of ICARE-based physics teaching materials, 3) analyze the effectiveness of ICARE-based teaching materials. The test subjects of this research were 28 students of class XI Science at Sma Muhammadiyah 1 Unismuh. Research method with 4D models. The instruments used in this research were validation sheets, practitioner assessment questionnaires, and test instruments for students' critical thinking abilities. Practicality criteria are seen from practitioners' assessments of teaching materials, and effectiveness criteria are seen from the average percentage of students' critical thinking ability improvement scores. Based on the results of the analysis, the following conclusions were obtained: (1) ICARE-based teaching materials which were developed based on expert assessment using Aiken's V index analysis were declared valid and suitable for use with slight revisions; (2) ICARE-based physics teaching materials in terms of teacher responses were in the category Very good; (3) the effectiveness of ICARE-based physics teaching materials analyzed using N-gain obtained an average value of 0.50, which is included in the medium category, meaning there is an increase in students' critical thinking abilities so it can be said that the ICARE-based physics teaching materials developed are effective and can improve abilities. students' critical thinking.
