Development of Physics Learning Instrument with Model Project Based Learning to Train Students’ Critical Thinking Skills

Abstract

This research is aimed to produce physics learning instrument with appropriate project based learning models and be able to train critical thinking skills in senior high school students. The research was conducted in the second semester of 2018/2019 academic year in the Senior High School of Amanatul Ummah Surabaya. Learning instrument developed refers to the design of 4-D development. The data were collected by observation, tests, interviews, questionnaires and documentation. Data analysis techniques used include analysis of validity. The results showed that the learning instrument developed (syllabus, lesson plans, teaching materials, student worksheet, and critical thinking skills test instruments) were valid categories, it can be concluded that the learning instrument developed has satisfy the criteria of validity so that it is worth using to train critical thinking skills in students.
