Abstract

This study aims to improve the understanding of the concept of the elements of plane figures in grade III students of Tanjungrejo 5 Public Elementary School through the application of an open-ended approach. The main problem found in the pre-action was the low ability of students to understand geometric concepts due to reliance on memorization and one definite answer. This Classroom Action Research (CAR) was carried out in two cycles using the Kemmis & McTaggart model which includes the stages of planning, implementation, observation, and reflection. The learning steps applied included open problem orientation, problem presentation, independent or group problem solving, and discussion of the results of the solution. The results showed a significant increase in conceptual understanding gradually. Students' classical mastery in the pre-action only reached 3.70% with a very poor category. After the action was carried out in cycle I, the mastery rate increased to 64.28%. In cycle II, classical mastery jumped to 92.80% and was included in the excellent category. This increase is supported by the theory of constructivism and the theory of cognitive flexibility which emphasize that knowledge is actively constructed by students through problems that challenge creativity. This approach has proven effective in making students more creative and able to solve mathematical problems with more than one solution.

Abstract

This study aims to improve student’s conceptual understanding of the diversity of landforms in Indonesia through the implementation of the Problem Based Learning (PBL) model supported by animated videos and formative assessment. The research employed Classroom Action Research (CAR) conducted in two cycles following the Kemmis and McTaggart model, which includes planning, action, observation, and reflection stages. The participants were 28 third-grade students of SD Negeri Tanjungrejo 5. Data were collected through observation, documentation, pre-test, and post-test to measure students’ conceptual understanding. The results showed a significant improvement in students’ learning outcomes across each cycle. In the pre-cycle stage, the classical completeness rate was only 17.86%. After implementing the learning model in Cycle I, the percentage increased to 57.17%. Further improvement occurred in Cycle II, where classical completeness reached 85.71%, exceeding the predetermined success indicator. The use of animated videos helped students visualize abstract concepts of landforms, while formative assessment provided feedback on students’ understanding during the learning process. Therefore, the integration of the Problem Based Learning model, animated video media, and formative assessment proved effective in enhancing students’ conceptual understanding and creating a more active and meaningful learning environment in elementary school.
