Problem-solving is a crucial 21st century skill that enables students to make informed decisions and apply knowledge in real-world contexts. To support this need, innovative learning models are required that integrate critical thinking and real-world application. This study investigates the effectiveness of a Design Thinking learning model combined with a STEM (Science, Technology, Engineering, and Mathematics) approach in improving students' problem-solving skills. The study involved 64 seventh-grade students from a public junior high school in Malang, Indonesia. Two classes were selected using purposive sampling: one as the experimental class, taught using the Design Thinking-STEM model, and the other as the control class with conventional instruction. A problem-solving test instrument, validated by experts, was used as the primary tool to assess students' abilities. The research employed a quantitative approach with a non-equivalent control group design. Data were analyzed using an independent samples t-test and normalized gain (n-gain). The findings showed a statistically significant difference between the two groups, with the experimental group demonstrating a higher n-gain score (0.58) than the control group (0.31). Indicator-wise analysis revealed that understanding the problem was the most improved aspect, while evaluation remained the lowest. These results suggest that the integration of Design Thinking and STEM effectively enhances students' problem-solving skills and promotes deeper learning through active engagement. © Published under licence by IOP Publishing Ltd.
