Application of Discovery Learning Model to Improve Students' Creative Thinking Skills on Reaction Rates Topic at SMAN 5 Palu

Abstract

This study aims to enhance students' creative thinking skills on the topic of reaction rates through the implementation of the Discovery Learning model in class XI A5 of SMAN 3 Palu. The research employed a Classroom Action Research (CAR) design conducted in two cycles, each consisting of four stages: planning, action, observation, and reflection. Data were collected using a creative thinking test based on four key indicators: fluency, flexibility, originality, and elaboration. The results indicated a significant improvement in students' creative thinking abilities. The average score increased from 48.16 in the pre-cycle, to 67.44 in the first cycle, and further to 80.20 in the second cycle. The mode value rose from 28 to 100, while the standard deviation decreased from 20.14 to 17.18, showing more consistent progress among students. The implementation of the Discovery Learning model combined with chemistry practicum activities proved effective in fostering an active, reflective, and collaborative learning atmosphere. Through this approach, students not only gained a deeper understanding of the abstract concept of reaction rates but also improved their creative thinking skills, including fluency, flexibility, originality, and elaboration.
