Abstract

Abstract: The type of this study is research and development of Biological problem-based learning devices on environmental decay and pollution materials. The aim of research and development are: (1) to develop learning instruments: student’s book, student’s worksheet (LKS), lesson plan (RPP), and learning achievement test (THB) that appropriate to problem-based learning, and (2 ) to evaluate the quality (validity, practicality, and effectiveness) of them. The developmental procedures of this problem-based learning devices referred to Thiagarajan4-D model. The results of this study showed that (1) generally, all the components of problem-based learning devices (prototype I) were valid. The results of validation analysis were RPP M= 4,08 (valid), student’s book M= 3,92 (valid), and LKS M= 4,07 (valid), whereas THB as device (quiz) was not validated, and (2 ) generally, the result of limited test in prototype II had fulfilled the criteria of practicality.
