PBL-BASED BIOLOGY MODULE TO IMPROVE STUDENTS CRITICAL THINKING SKILLS

Science Education

Problem Based Learning (PBL) is one of the learning model which based on constructivism theory that most appropriate to be integrated into the module. The integration of PBL into the module can replace the previous teaching materials that can’t improve the students' critical thinking skills in analyzing the abstract material like excretion system material in high school. The purpose of this study is to describe PBL-based biology module that are effective for improving critical thinking skills of high school students. The type of study is a research and development. The tested design of this study is Pre-Experimental Design which used one group pretest-posttest design. The sample of study were XI grade students of Muhammadiyah 2 Genteng High School and Genteng 2 Public High School in the odd semester of the 2018/2019 academic year. The Improvement students' critical thinking skills were analyzed by the gain score formula. To get the gain score, the product is tested on the formative evaluation, semi-summative evaluation, and dissemination stage. Based on the data collected on the overall stage obtained the average gain score in the high criteria. It can be conclude that the PBL-based biology module on excretion system material for critical thinking skills effectively able to improve students critical thinking skills.
