Enhancing the Problem-Based Learning Model Assisted by Domino Media to Improve Critical Thinking in IPAS Learning for Grade IV Students of Margoyasan State Elementary School in the Academic Year 2022/2023
A significant number of students have obtained unsatisfactory learning outcomes. This issue can be attributed to the inadequacy of students' critical thinking skills in effectively solving problems during the learning process. The purpose of this research is to analyze the implementation of the Problem-Based Learning teaching model in enhancing critical thinking among fourth-grade elementary school students, with the assistance of domino media, at SDN Margoyasan, Yogyakarta. The research method employed in this research is Collaborative Classroom Action Research (CCAR) using the Kemmis and McTaggart model, conducted in two cycles. The subjects of the research were 25 fourth-grade students. This research was carried out during the second semester of the academic year 2022/2023. Data collection was conducted through observation, interviews, and documentation. The data analysis techniques employed were both qualitative and quantitative. The gathered data was further processed using quantitative methods. Based on the analysis of the implementation of the Problem-Based Learning teaching model in the learning process, it is evident that it can enhance students' critical thinking. Starting from the pre-cycle phase to cycle 2, the average critical thinking dimension of students improved significantly. Initially, in the pre-cycle, it was 45.8%, then in cycle I, it increased to 70.7%, and in cycle II, it reached 85.6%. The utilization of Problem-Based Learning assisted by domino media has a significant impact on students' critical thinking abilities. Moreover, it is noteworthy that the participants exhibit varied experiences in the learning process, owing to the demand for problem-solving during their educational journey. As a result, the research's implications are anticipated to motivate educators to adopt this instructional model in their teaching practices. Thereby augmenting the students' proficiency in comprehending the subject matter effortlessly throughout the learning process.
