Abstract

Abstract: The purpose of this study is to describe the application of the Van Hiele learning model that can improve student learning outcomes in the material relationship lines and angles in class VII Muhammadiyah Middle School 1 Palu. This type of research is classroom action research (CAR). The design of the study was based on the research design of Kemmis and Mc. Taggart consists of four components, namely (1) planning, (2) action, (3) observation, and (4) reflection. This research was conducted in two cycles. The research subjects were seventh grade students of Muhammadiyah Middle School 1 Palu in the 2017/2018 school year, totaling 25 students. Data collection techniques in this study were observation, tests, interviews, and field notes. The results showed that the application of the Van Hiele learning model could improve student learning outcomes by following the phases of Van Hiele's learning model, namely: (1) inquiry, (2) directed orientation, (3) description, (4) free orientation, and ( 5) integration. In the first cycle the percentage of classical learning completeness was 47.83% and in the second cycle the percentage of classical learning completeness increased to 86.96%. In addition, the results of observations of teacher activities in managing learning in the first cycle and second cycle are in the very good category. The results of observations of student activities in following the learning process in the first cycle are in the good category and the second cycle is in a very good category.

Abstract

Understanding students' metacognitive skills in solving math problems concerning their mathematical abilities is crucial foridentifying the cognitive processes involved in problem-solving. This study investigates the metacognitive skills of SMPN 3 Palu students with varying mathematical abilities in problem-solving. It focuses on students in class VIIJ during the 2022/2023 academic year, individually analyzing one high-ability and one low-ability student. The research, descriptive in nature, employs qualitative methods using written assignments and interviews for data collection. This study's analysis involved condensing data, presenting findings, and drawing conclusions. The findings reveal distinct approaches between high and low mathematical ability subjects. High-ability students consistently apply all three metacognitive skills (planning, monitoring, and assessment) across each problem-solving stage. Conversely, low-ability students demonstrate a limited use of metacognitive skills. While they employ planning at each stage, during implementation and result review, they primarily engage in planning and monitoring, neglecting assessment. Ultimately, it underscores the critical role of metacognitive skills in mathematical problem-solving, highlighting differences in their application between students of varying mathematical abilities.
