The mastery of grade 4 of elementary school students' concepts on energy through the implementation of the RADEC learning model

Abstract

This study was aimed to determine students' concept mastery on energy topic before and after the implementation of Read-Answer-Discuss-Explain-and Create (RADEC) learning model. This study was carried out using pre-experimental method with one group pre-test and post-test design. The participants of this study were eight elementary school students in which five of them from a public elementary school in Bandung, two students from a public elementary school in Tasikmalaya, and a student from a public elementary school in Ciamis. The instrument in this study was a four-tier test in the form of google form. The data were analyzed quantitatively and the result indicated that 50% of the students experienced misconceptions in learning energy topic. After the RADEC learning model was implemented, 77% of the students acquired scientific conception on the energy topic. Based on the Paired Sample T-Test result (p 0.015 <0.05), there was a difference in the concept mastery between pre-test and post-test scores. The obtained NGain score of the pre-test and the post-test in this study was 0.67 which was considered as moderate category. For further researchers, they were recommended to involve more participants so that the findings could be more useful.
