The effect of STEM-based (Science, Technology, Engineering, and Mathematics) learning model toward the students' mathematical problem-solving ability in SD Muhammadiyah Condongcatur, Yogyakarta

Abstract

This study aims to determine (1) the students' mathematical problem-solving ability taught using STEM-based (Science, Technology, Engineering, and Mathematics) learning model, (2) students' mathematical problem-solving ability taught using expository learning models, (3) whether there is a difference in the effect of STEM-based learning model with expository learning models in improving students' mathematics learning achievement. This research was an experimental research design with quasi experimental design (Quasi Experimental Design). The population in this study was all grade V SD Muhammadiyah Condongcatur Yogyakarta. The sample in this study was class V-1 as an experimental class with 33 students and class V-2 as a control class with 33 students. The findings in this study indicate that the class taught using STEM-based learning model has Mean 31.9697 and the class taught using the expository model has an average value of 28.5758. The results of the hypothesis test show that Tcount> Ttable is 2.925> 1.996 with the conclusion that the mathematical problem-solving ability of students taught with STEM learning model is better than the class which is taught with expository learning models.
