EKSPERIMENTASI MODEL CORE DENGAN CRT TERHADAP KEMAMPUAN PEMECAHAN MASALAH DITINJAU DARI SELF REGULATED LEARNING

This research aims to determine the effect of implementing the CORE learning model with the CRT approach on problem-solving abilities from a self-regulated learning perspective. This study was conducted as a quasi-experimental method with a 2×3 factorial design. The population included all eighth-grade students of SMP Negeri 1 Semin in the 2025/2026 academic year, with 32 students from classes VIII D and VIII A selected using cluster random sampling. Data were obtained through problem-solving ability tests, SRL questionnaires, and documentation. Data analysis was performed using a two-way ANOVA with a significance level of 0.05. The results showed that implementing the CORE learning model with the CRT approach improved problem-solving abilities, the level of self-regulated learning had a positive effect on problem-solving abilities, and the effect of the learning model on problem-solving abilities was independent of self-regulated learning, and vice versa. The CORE learning model with the CRT approach can be implemented and modified using technology-based learning media to improve problem-solving abilities.
