Abstract: This study aimed to examine the effectiveness of the hybrid project-based learning model to improve critical thinking and creative thinking skills. This research was a quantitative research with pretest-posttest control group design. The subjects were the second semester students of the elementary school teacher education major in 2022/2023 academic year. The research data was measured in terms of validity, practicality, and effectiveness of the research instrument. The results indicated that (a) the hybrid project-based learning model developed by the researchers were very valid with a percentage of 94%, (b) the students’ responses in experimental class were very good with a percentage of 94%, while for the control class it was 69% in the unfavorable category, (c) the t-test analysis obtained 0.023 <0.05 with the N-Gain test results of 79.20%, meaning that there was a significant difference and an increase in students’ critical thinking skills, and (d ) the t-test analysis obtained 0.019 <0.05 with the N-Gain test results of 77.11%, meaning that there was a significant difference and an increase in students’ creative thinking skills. In conclusion, the hybrid project-based learning model is feasible to use and can improve students’ critical thinking and creative thinking skills.
