Development of STEM Integrated PBL-Based Student Worksheets in Energetic Materials of First-Year Students

Abstract

This study aims to produce STEM integrated problem-based student worksheets by looking at the validity, practicality and effectiveness of student worksheets in student learning activities.. This research method is a research development using the Plomp’s model. The design of this study was the design of one pretest-posttest group. The research subjects were students of chemistry majors Padang State University 2019. The research instruments used were validation sheets, practicality sheets and observation sheets of learning activities. This research shows that worksheet has a very high level of validity, very high level of practicality by students and high by the lecturer. The results showed that overall the average student learning activities were very high. This shows that the worksheets that has been produced can be used as one of the teaching materials in the learning process on energetic material.
