Implementation of Project Based Learning Based on STEM Approach to Improve Students’ Problems Solving Abilities

Abstract

Abstract This study aims to analyse the improvement of the problems solving abilities by implementing project-based learning with a STEM approach using a distance learning strategy. This research method is a pre-experimental pretest-posttest one group design. The population of this research was the 5th-grade students of Magelang Elementary School in 2019/2020. The sample selection using purposive random sampling with 78 students. The research subjects were elementary school students with symbols A, B, C, and D located in several areas of the City of Magelang, Central Java. Data collection techniques used in this study are tests of problemsolving ability and observation. Quantitative data analysis techniques used were gain normality test and one-sample t-test. The results showed that the problem-solving ability of students increased significantly with a gain factor is 0.44 (enough), a one-sample t-test with a sig (2-tailed) is 0,121 (significantly) and the results of observations of the implementation of learning are 92% (very good). In other words, the project-based learning based on STEM approach with distancing learning strategies could significantly improve students’ problems solving abilities.
