THE EFFECTIVENESS OF A STEM-BASED SCIENCE COMIC E- WORKSHEET ON ECOLOGY MATERIALS FOR ENHANCING STUDENTS’ PROBLEM-SOLVING SKILLS

Hana Nur Fadilah, Parmin Parmin

Abstract


Problem-solving skills are among the essential competencies required for 21st-century science education; however, students' proficiency in these skills remains relatively low, particularly in ecology learning. This study aimed to analyze the effectiveness of a STEM-based science comic e-worksheet in enhancing students' problem-solving skills. The study employed a pre-experimental one-group pretest-posttest design involving 31 seventh-grade students at a public junior high school in Semarang, Indonesia. The research instrument consisted of a problem-solving skills test developed based on Polya's problem-solving indicators. Data were analyzed using a normality test, paired-sample t-test, and normalized gain (N-Gain) test. The mean pretest score increased from 46.27 to 77.79 on the posttest. The average N-Gain score was 0.6025, indicating moderate improvement, with the highest gains in understanding the problem (0.8367) and looking back (0.7161). The results demonstrate that the STEM-based science comic e-worksheet effectively enhances students' problem-solving skills in ecology.
