Abstract

This study examines the influence of a Problem-Based Learning (PBL)–based Student Worksheet (LKPD) assisted by Wordwall media on the critical thinking skills of fifth-grade students in science learning, focusing on the aspects of focus, reason, and inference. Employing a quantitative approach with a quasi-experimental design, the research involved an experimental group using PBL-based LKPD with Wordwall and a control group receiving conventional instruction. Data were collected through tests, observations, interviews, and documentation, while instrument validation included expert judgment, Aiken’s V analysis, reliability testing, empirical validation, item difficulty, and discrimination analysis. The prerequisite normality and homogeneity tests indicated non-normal and non-homogeneous data, leading to the use of nonparametric statistical analyses. The Mann–Whitney test results showed significant differences between the experimental and control groups across all three aspects of critical thinking, with Asymp. Sig (2-tailed) = 0.000 < 0.05. N-Gain scores demonstrated high effectiveness in the experimental group (Focus = 96.70%, Reason = 87.90%, Inference = 79.30%), whereas the control group showed only moderate improvement. Correlation analysis using Spearman’s rank test further revealed very strong correlations among the Focus, Reason, and Inference dimensions. The findings conclude that the PBL-based LKPD assisted by Wordwall media is effective in improving students’ critical thinking skills and supports more engaging, interactive, and student-centered science learning in elementary classrooms.

Abstract

This study investigated the effect of Problem-Based Learning (PBL)-based student worksheets (LKPD) assisted by Wordwall media on fifth graders’ critical thinking skills in science learning. The study focused on three dimensions of critical thinking: focus, reason, and inference. A quantitative approach with a quasi-experimental design was employed. The experimental group used PBL-based LKPD integrated with Wordwall media, while the control group received conventional instruction. Data were collected through tests, observations, interviews, and documentation. Instrument validation included expert judgment, Aiken’s V analysis, reliability testing, item validity, item difficulty, and discrimination analysis. The results of the normality and homogeneity tests indicated that the data were non-normal and non-homogeneous; therefore, nonparametric statistics were applied. The Mann–Whitney test showed significant differences between the experimental and control groups across all critical thinking aspects with Asymp. Sig. (2-tailed) values of 0.000 < 0.05. N-Gain analysis demonstrated high effectiveness in the experimental group for focus (96.70%), reason (87.90%), and inference (79.30%), whereas the control group showed only moderate improvement. Spearman rank correlation analysis further revealed very strong correlations among the three critical thinking dimensions. The findings indicate that PBL-based LKPD assisted by Wordwall media effectively improves students’ critical thinking skills and promotes more interactive and student-centered science learning.
