摘要：This paper addresses how to plan and implement the Group Investigation (GI) in an attempt to enhance the efectiveness of physics learning. It reports research with 30 Year-10 high school students studying temperature and heat transfer, during which the researchers employed a participatory action research approach. The research tools used to achieve the research aim were the written test, observations of teacher and student activities. To assess the students’ performance, a written test was administered following the validity and realibility of item test. Of 24 items was tried out, 18 items were valid with Cronbach Alpha reliabilities > 0.70. The teacher roles in learning activities were evaluated by using the classroom observation protocols conducted by three observers with ICC coefficient varrying above 0.71 to below 0.54. The results suggest that the GI instructional strategy can contribute positively to the efectiveness of physics learning (1) in terms of students’ performance on the test, and (2) by adaptating stage 1 (identifying the topics) and stage 2 (planning the investigation).
