Abstract

This study aimed to determine the effect of the Problem-Based Learning model on the critical thinking skills of fourth grade students in IPAS learning at SDN Lasoani. The study employed a quantitative approach using a pre-experimental method with a one-group pretest and posttest design. The sample consisted of 26 fourth grade students selected through purposive sampling. Data were collected using essay tests developed based on Ennis’s critical thinking indicators and analyzed using descriptive statistics and the Wilcoxon Signed-Rank Test. The results showed that the mean score increased from 61.15 on the pretest to 82.31 on the posttest. Improvements were observed across all critical thinking indicators, with the highest increase found in the drawing conclusions indicator. The Wilcoxon Signed-Rank Test yielded a significance value of 0.001 (p < 0.05), indicating a significant difference between pretest and posttest scores. These findings demonstrate that the Problem-Based Learning model effectively improves students’ critical thinking skills through contextual problem-solving, investigation, discussion, and reflection activities. Therefore, PBL can be considered an effective instructional approach for enhancing critical thinking skills in IPAS learning within the context of the Merdeka Curriculum.

Abstract

Critical thinking is an essential competency that should be developed in elementary education to support students in solving problems and making informed decisions. However, students' critical thinking skills in Natural and Social Sciences (IPAS) remain relatively low due to the limited use of interactive digital learning media. This study aimed to examine the effect of Canva-based interactive learning media on the critical thinking skills of sixth-grade students at SD Inpres 1 Tondo. A quantitative approach with a pre-experimental method employing a One Group Pretest–Posttest Design was used. The participants consisted of 14 sixth-grade students selected through total sampling. Data were collected using a multiple-choice critical thinking test and analyzed using descriptive statistics and the Paired Sample t-test with SPSS version 25. The findings revealed that the mean score increased from 61.79 on the pretest to 71.79 on the posttest, representing an improvement of 10.00 points. The Paired Sample t-test indicated a statistically significant difference between the pretest and posttest scores (p < 0.001). These findings demonstrate that Canva-based interactive learning media effectively enhance students' critical thinking skills and can serve as an innovative digital learning medium to support more engaging and meaningful IPAS instruction in elementary schools.
