The Effect of a Worksheet Assisted Project-Based Learning Model on Students’ Creative Thinking Skills in the Reproductive System Unit for Grade XI Students at MAN 1 Pekanbaru

Project-Based Learning (PjBL) is a learning strategy that can enhance competencies, including creativity. Creative thinking is one of the 21st-century skills that students need to possess. This study was motivated by the low level of students’ creative thinking skills, as indicated by a pretest average score of 49.14, which is below the Learning Objective Mastery Criteria (KKTP) of 78. Previous research has shown that PjBL and Student Worksheets (LKPD) can support the development of creative thinking skills; however, research integrating both approaches into the reproductive system curriculum at the Madrasah Aliyah level remains limited. This study aims to determine the effect of PjBL supported by Student Worksheets (LKPD) on the creative thinking skills of 11th-grade students at MAN 1 Pekanbaru. The study employed a quantitative approach using a quasi-experimental research method through a pretest-posttest control group design. The sample consisted of Class XI.2 Health 1 as the control group and Class XI.3 Health 2 as the experimental group, each comprising 33 students. The instrument used was a creative thinking test. The results of the hypothesis test showed a significant difference (Sig. 0.000 < 0.05; calculated t-value 5.593 > critical t-value 1.998). The average posttest score for the experimental group was 78.30% and for the control group 69.19%, with a difference of 9.11 points. PjBL supported by LKPD had a significant effect on creative thinking skills.
