Improving Students’ Mathematics Learning Outcomes through Demonstration Methods in Geometry Materials

Abstract

This study aims to examine efforts to improve student learning outcomes through demonstration methods in mathematics subjects with building materials in the form of blocks and cubes for fourth grade students of MIN Medan Tembung. This type of research uses classroom action research (CAR), with subjects covering 37 fourth grade students at MIN Medan Tembung. The results of this study conclude that the application of the demonstration method can improve the learning outcomes of fourth grade students at MIN Tembung in mathematics lessons on building materials (cubes and blocks). This is evidenced by the results of the student's pre-test which was originally low, namely 38.64 (none even completed according to the Minimum Completeness Criteria/KKM). The results of the final test in the first cycle that did not use the demonstration method (still conventional method) showed an increase, where 7 students had achieved the KKM score (18.9%) while the other 30 students had not reached the KKM (81.1%). Furthermore, the results of the final test in the second cycle that had used the demonstration method showed a significant increase, where there were 32 students (86.48%) who met the KKM and 5 students (13.52%) who had not reached the KKM.
