TEACHING MODEL DEVELOPMENT TO PROMOTE THE CRITICAL THINKING SKILLS IN SCIENCE COURSES FOR GARADE 8 STUDENTS

Abstract

This research was created for the purpose of developing a teaching for promoting the critical thinking skills in the science courses for the Grade 8 students, using the research and development process, consisting of 4 steps as follows: Step 1: study the components, needs and guidelines for educational development Step 2: creating a teaching model, Step 3: teaching model experiment, and Step 4: the study about satisfaction. The sample of this study was group of 50 students of Grade 8 at Triamudomsuksanomklao Kabinburi School in the second semester of the 2018 academic year.

The results revealed that the form consisted of 6 components: 1) principle(s), 2) objective(s), 3) procedure(s), 4) response(s), 5) social system(s) and 6) supporting system(s). There were seven steps of the teaching process as follows: A: Activating and application, B: Brainstorming, C: Critical Thinking, D: Discovering, E: Evaluations, F: Feat and G: Genius. In terms of the effectiveness of the teaching style to promote critical thinking skills for Grade 8 students, the value was 82.87/82.65 which was higher than the 80/80 threshold set. The students have developed the critical thinking skills after studying with a teaching style(s) to promote the critical thinking skills in science for students in Grade 8; it showed that the result obtained was higher than before studying statistically significant at the .05 level. Based on the results of the student satisfaction level with the implemented teaching style(s) for promoting the critical thinking skills in science for Grade 8 students, the overall level was at a high level.
