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

This research aims to improve the learning outcomes of mathematics students in grade IV of SD Inpres 3 Tondo through the application of the Quantum Teaching learning model. This research uses the Classroom Action Research (PTK) method which is carried out in two cycles. Each cycle consists of the stages of planning, implementation of actions, observation, and reflection. The research subjects amounted to 34 grade IV students of SD Inpres 3 Tondo. Data collection techniques are carried out through tests, observations, and documentation. Data were analyzed using quantitative and qualitative analysis. The results of the study showed that there was an increase in students' mathematics learning outcomes in each cycle. In the pre-action stage, the average score of students was 45.74 with classical learning completeness of 5.9%. After the application of the Quantum Teaching model in cycle I, the average score increased to 71.76 with classical learning completeness of 67.65%. In cycle II, the average score increased again to 79.12 with classical learning completeness reaching 91.18%. These results show that the application of the Quantum Teaching learning model is able to improve the mathematics learning outcomes of grade IV students of SD Inpres 3 Tondo. Thus, the Quantum Teaching model can be one of the effective learning alternatives to improve the understanding and learning outcomes of mathematics in elementary school.
