The Development of Worksheets and Electronic Learning Materials Based on Project Based Learning on the Subjects of Physics

Abstract

This study aimed to develop valid, practical and effective physics worksheets and electronic learning materials based on project based learning in grade XI students in wave subject. The type of this research was research and development(R&D) with 4D development model developed by Thiagarajan, et.al. This research was conducted at SMAN 1 Samarinda with 33 grade XI students of science class. The data in this research were collected using questionnaires of students' responses, expert assessment sheets, project appraisal sheets and tests to determine students' learning outcomes. Based on the result of the expert’s assessment for worksheets and electronic learning materials can be concluded that the initial product was valid. Moreover, based on the result of paired T-test analysis between post-test and pretest showed an increase in student learning outcomes and N-Gain score showed that the improvement was categorized as high. Also, the percentage of students' responses for worksheets and electronic learning materials showed the positive responses from students. In summary, the worksheets and electronic learning materials that have been developed were valid, effective and practical to use.
