Abstract

Learning angle concepts remains challenging for many elementary school students because mathematics instruction is still dominated by teacher explanations, leaving students with limited opportunities to actively construct their own understanding. Consequently, abstract mathematical concepts are often not fully understood. This research sought to enhance fifth graders' mathematical understanding of angles by introducing them to the Student Teams Achievement Division (STAD) cooperative learning approach, which is supported by Polypad media. Classroom Action Research (CAR) was used in the research, which was carried out in two cycles, according to the paradigm proposed by Kemmis and McTaggart. Data were collected through achievement tests, classroom observations, and documentation, then analyzed using descriptive quantitative techniques supported by descriptive qualitative analysis. The findings showed improvements across all domains of learning outcomes. Cognitive learning mastery increased from 55.56% in Cycle I to 83.33% in Cycle II. Likewise, affective learning mastery improved from 72.22% to 100%, while psychomotor learning mastery rose from 44.44% to 94.44%. Overall, integrating the STAD cooperative learning model with Polypad created a more participatory learning environment, which contributed to improving students' mathematics learning outcomes on angle concepts.
