THE EFFECTIVENESS OF THE RADEC LEARNING MODEL ON HIGHER ORDER THINKING SKILLS (HOTS) IN SCIENCE LEARNING

Abstract

This research aims to determine the effectiveness of using the RADEC learning model on Higher-Order Thinking Skills (HOTS) abilities in learning science and technology regarding changes in the shape of objects. This research was conducted at MIPK Al-Islam Pucangsawit for the 2023/2024 academic year. The population in this study were all class IV students at MIPK Al-Islam Pucangsawit, totaling 31 students taken using a saturated sampling technique. The instrument used in this research was literacy-based HOTS questions to determine the level of critical, analytical, and logical thinking in students. The research design uses quantitative research with a One-Group Pretest-Posttest design and data analysis of test results using the help of the IBM SPSS 25 program. For data analysis using the normality test (Shapiro Wilk Test), homogeneity test (Lavene Test), and hypothesis testing using Paired Sample T -Test. From the research results obtained through literacy questions, the students HOTS ability averaged 43.03, and after using the RADEC learning model the students average increased to 79.24. The N-Gain score was 0.74 in the high category. Meanwhile, the percentage of the N-Gain score is 74.45, meaning that the effectiveness of using the RADEC learning model is quite effective. Hypothesis testing using the Paired Sample T-Test obtained a sig-tailed value of 0.000 where the sig value was <0.05, meaning that H0was rejected and Ha was accepted. Based on the research that has been conducted, it can be concluded that the RADEC learning model is quite effective for use in science learning to determine the HOTS ability level of class IV students.
