The Development of Learning Kits based on Causality Model to Improve Creativity Thinking Skills Momentum and Impulse of Students

This research aims to determine the feasibility of a causality model learning approach to enhance creative thinking skills in the context of momentum and impulse within the field of physics. The causality model approach provides a structured framework that guides students in their learning, placing emphasis on the development of their ability to analyze cause and effect elements in a given phenomenon and construct arguments that explain how causal conditions lead to specific effects. This study follows a Research and Development methodology, employing a comprehensive 4-D model that encompasses the stages of defining, designing, developing, and disseminating. The resulting learning kit comprises a meticulously designed syllabus, well-crafted lesson plans, and carefully constructed pre-tasks. To assess the effectiveness of the learning kit, a validation questionnaire employing a Likert scale ranging from 1 to 4 was administered. The scale of Likert scale and the development of the learning kit integrated with creative thinking skills indicators. There were fluency, flexibility, originality, and elaboration. The data for validation was sourced from expert lecturers and seasoned high school physics teachers who acted as validators. The outcome of the learning device validation process yielded an impressive average validation value of 87.50%, surpassing the criteria for high validity. Moreover, the reliability score was reported as 92.30%. Based on the validation results, it can be concluded that the causality model learning approach is suitable for improving the creative thinking skills of students studying momentum and impulse in science. Teachers are encouraged to utilize this learning kit, which is based on a development-oriented causality learning framework, to enhance students' creativity skills. In order to measure and monitor creative thinking skills, a pretest and posttest could be integrated into the class as assessment instruments.
