The Use of Concrete Objects Media on Students' Learning Outcomes of Nets - Cube Nets and Beams

The purpose of this study was to describe the effect of using concrete objects on learning outcomes for nets of cubes and blocks in fourth grade students of SDN 60 East City, Gorontalo City. This type of quantitative research is descriptive. One group prettest-posttest research design. This research uses data collection techniques through tests and documentation. The sample of this research is the fourth grade students as many as 25 people. The results of the study show that the effect of using concrete objects has a significant effect on learning outcomes in mathematics. This result can be seen from the average pretest value in learning is 49.4 and after learning the posttest average value becomes 80.2. This is reinforced by the results of hypothesis testing with posttest t-test at significant = 0.05, obtained tcount 7,908 with ttable is 2,063 or (tcount 7,908 ttable 2,063). Thus, it is concluded that there is an effect of using concrete object media on the learning outcomes of cube and block nets in fourth grade students of SDN 60 East City, Gorontalo Cit
