The Development Of Physics Curriculum By Using Inquiry-Based Learning Method To Enhance Critical Thinking For Secondary School Students In Grade 7, Kob High School, Cambodia

摘要

          The purpose of this research was to develop and study the effectiveness of the physics curriculum by using an inquiry-based learning method to enhance critical thinking for secondary school students in grade 7, Kob High School, Cambodia. There were 4 steps as follows: Step 1) Studying fundamental data from the curriculum framework of general education and technical education of Cambodia (2016), documents, and research which involved curriculum development. Studying opinions, the needs of 3 experts, 7 school directors, 5 physics teachers, and 58 students were found to have demands for the development of this physics curriculum. Step 2: Curriculum development has 7 components: 1) Curriculum aims 2) Curriculum objectives 3) Course content 4) Course structure 5) Learning activities 6) Media and learning resources and 7) Measurement and Evaluation. The quality was determined by 5 experts to be consistent and appropriate at the highest level (M = 4.56, S.D.=0.29). Step 3: Implementation of the physics curriculum was applied to a sample group of 26 secondary school students at Kob High School, Cambodia, Semester 2, academic year 2023. It was found that the students had a good critical thinking level (M = 2.53, S.D. =0.19), learning outcomes in Physics after studying were higher than before studying with statistical significance at the 0.05 level, satisfaction of study at a high level (M = 4.26, S.D. =0.32). Step 4: Evaluate and develop the curriculum. It was found that the curriculum has 7 elements: 1) Curriculum aims 2) Curriculum objectives 3) Course content 4) Course structure 5) Learning activities 6) Media and learning resources and 7) Measurement and Evaluation that consist of six inquiry-based learning steps: 1) Defining a problem or asking a question 2) Setting a hypothesis 3) Designing an experiment to prove the hypothesis 4) Testing the hypothesis 5) Result and 6) Evaluation.
