Abstract

This study aims to determine: (1) the level of students' critical thinking skills before and after the implementation of PBL with CRT; (2) the improvement in students' critical thinking skills following the implementation of PBL with CRT; and (3) the significance of the improvement in students’ critical thinking skills after applying the PBL with CRT. This study employed a pre-experimental one-group pretest–posttest design. The research population consisted of eighth-grade students at SMP Negeri 33 Makassar, with a total of 276 students across nine classes. Purposive sampling was used to select class VIII.1, which consisted of 32 students from diverse ethnic backgrounds. The research instrument used was a critical thinking skills test. Data were analyzed using both descriptive and inferential statistics. The results showed that (1) students' critical thinking skills before the implementation of PBL with CRT were categorized as low, with a mean score of 6.41. After the implementation, students' critical thinking skills improved significantly, reaching a high category with a mean score of 13.62. (2) The N-Gain score of 0.52 indicated a moderate improvement. (3) Overall, there was a statistically significant increase in the critical thinking skills of the students after the implementation of PBL with CRT.

Abstract

This study aims to determine: 1) The level of students’ learning independence and outcomes before and after using wizer.me-based electronic worksheet, 2) The level of students’ learning independence and outcomes before and after using using printed worksheet, 3) Improvement of learning independence and learning outcomes, 4) The influence of wizer.me-based electronic student worksheet on learning independence and learning outcomes. This research using a Quasi Experimental Design with a Nonequivalent Control Group, involving 48 students from two grade VIII classes at SMPN 27 Makassar. Data were collected through 25 test items on learning outcomes and 25 questionnaire statements on learning independence, and analyzed using descriptive and inferential statistics. Analysis results showed that: 1) wizer.me-based electronic student worksheet improved learning independence from 72.64 to 84.44 and learning outcomes from 7.48 to 15.48; 2) printed student worksheet increased learning independence from 66.39 to 74.04 and learning outcomes from 6.91 to 10.96; 3) the experimental group had N-Gains of 0.43 in learning independence and 0.48 in learning outcomes, while the control group had N-Gains of 0.23 and 0.22, respectively; 4) wizer.me-based electronic student worksheet led to more significant gains in both learning independence and learning outcomes compared to printed student worksheet.
