The use of STEM project-based learning toward students’ concept mastery in learning light and optics

Abstract

Learning process in some school is still in the form of direct transfer from teacher to students, whereas students will learn better if the learning process is meaningful. The aim of this study is to investigate the effect of STEM Project-Based Learning on students’ Concept Mastery in learning light and optics. The method that is used in this study is a weak experiment with one group pre-test and post-test design. The population of this study is 8th-grade students in Junior Secondary School “X” that is located in Bandung, Indonesia. The sample is chosen by purposive sampling technique consist of 25 students. The result of this study shows that students concept mastery improves from pre-test and post-test. The improvement of concept mastery is obtained as much as 0.53 that categorized as a medium improvement. Based on the result STEM Project-Based Learning give a better effect on students’ concept mastery, so it can be considered as an alternative teaching model that can be implemented in Junior Secondary Schools.
