Abstract

This research aims to investigate the influence of the Problem Based Learning Model on the critical thinking abilities of fifth-grade students at State Elementary School 11 Pontianak Kota in the object of Natural and Social Sciences. The research employed an Experimental Method, specifically a Quasi Experimental Design using Nonequivalent Control Group format. The population in this research consisted of all fifth-grade students. Sampling was carried out using a Probability Sampling Technique, specifically Saturated Sampling. Data were collected through measurement techniques using instruments in the form of written essay tests. Based on the results of hypothesis testing using the Paired Sample t-test formula, the tcount is 3.74 and the ttable (α = 5% and dk = n - 1 = 21) is 2.08, which means tcount > ttable, then 𝐻 is rejected and is accepted. 0 𝐻𝑎 The Effect Size calculation yielded a value of 0.58, which is categorized as moderate, therefore it can be concluded that the Problem Based Learning Model has a positive and significant impact on the critical thinking abilities of fifth-grade students at State Elementary School 11 Pontianak Kota in Natural and Social Sciences subjects.

Abstract

This classroom action research was motivated by the low IPAS learning outcomes of fifth-grade students at SD Negeri 03 in Pontianak Kota, which were caused by the predominance of conventional, teacher-centered instruction. This study aimed to improve students’ IPAS learning outcomes through the implementation of a simulation-based Problem-Based Learning (PBL) model. The research method used was collaborative Classroom Action Research (CAR) based on the Kemmis & McTaggart model, conducted in two cycles. The research subjects consisted of 29 students. Data were collected using test techniques (multiple-choice evaluation questions) and non-test techniques (observation sheets), then analyzed using quantitative and qualitative descriptive methods. The results showed that in the pre-cycle phase, the class average was only 67.24, with a classical mastery rate of 37.93% (11 students achieved mastery). After implementing the intervention in Cycle I, the class average increased to 76.38 with a classical mastery rate of 68.97% (20 students met the criteria) and an N-Gain value of 0.28 (low category). In Cycle II, there was a significant jump in results, with the class average reaching 85.17, the percentage of students meeting the standard reaching 89.66% (26 students met the standard), and the N-Gain value rising to 0.37 (moderate category). Cumulatively, the improvement from the pre-cycle to Cycle II resulted in a total N-Gain index of 0.55 (moderate category). The success indicator targets were optimally met, leading to the conclusion that the implementation of a simulation-based PBL model is effective in improving elementary school students’ IPAS learning outcomes.
