Enhancing concept mastery of students through STEM-project in scientific inquiry learning

Abstract

This study aims to examine the effect of STEM project in scientific inquiry learning towards enhancing concept mastery of students. The research method used was a quasi-experiment with the one group pretest-posttest design. Quantitative data was obtained through instrument of concept mastery test using a two-tier multiple choice instrument and then analyzed using dependent t-test. Based on the result of dependent t-test was found that there was significance difference between the pretest and posttest scores of students with sig = 0.000 (p<0.05). The enhancing between pretest and posttest score was obtained from N-gain analysis, the value of gain index is 0.64 showed that the enhancing of students' concept mastery is in medium category. Based on the results obtained from this study, it showed that STEM project in scientific inquiry learning had positive impact on concept mastery of students, therefore it can be used as an alternative learning model in science learning that integrates technology.
