Abstract
This study investigates the effect of the Investigation Through Cooperative Problem Solving (ITCPS) learning model on students computational thinking (CT) skills in Grade VII science learning. CT, encompassing decomposition, abstraction, pattern recognition, and algorithmic thinking, is an essential 21st-century skill. However, many students still face challenges in developing CT due to limited use of innovative, inquiry-based learning approaches. A quasi-experimental method with a nonequivalent pretest-posttest control group design was applied. The sample comprised seventh-grade students at SMP Negeri 3 Sukoharjo in the 2024/2025 academic year, selected through cluster random sampling. An essay test was used to assess four CT indicators, and data were analyzed using the Mann-Whitney test. The results showed a significant difference in CT abilities between students taught with the ITCPS model and those taught with a problem-solving mod el (p < 0.001). The ITCPS model effectively improved CT by engaging students in structured, collaborative, and investigation-based problem-solving activities. In conclusion, ITCPS is a promising instructional model for enhancing CT in science learning and is recommended for wider application in junior high schools.
