Stacking Analysis on the Application of the RADEC Model to the Creativity of Fifth Grade Elementary School Students on Water Cycle Material

This study uses stacking analysis to analyze the application of the RADEC model (Read, Answer, Discuss, Explain, Create) to students' creativity in the water cycle material. This research is quantitative experimental research. The research subjects were fifth-grade elementary school students for the 2022/2023 school year, totaling 21 students. The research instrument was a creative attitude scale of 22 statements given before and after learning. The data obtained will be processed using the RASCH model through stacking analysis with the Winstep application. The results showed a change in students' creativity after the RADEC model was applied by 24% in the very good category and 76% in the fairly good category. This study's results prove that applying the RADEC model can increase students' creativity in the water cycle material
