Student Concept Mastery on Coloid Material Through Radec Learning

Abstract

Mastery of concepts is still the main standard of learning success in Indonesia. This study aims to analyze students' conceptual mastery of colloidal material through the RADEC (Read, Answer, Discuss, Explain, and Create) learning model. The research method used is the Pre-Experiment method with the research design of One Group Pretest-Posttest Design. The number of subjects in this study were 18 students. Data were collected using 25 multiple choice items used for pretest and posttest. Data were analyzed through normality test, t test and N-gain using SPSS version 21 for windows. The results of the Paired Sample T-Test showed that there was a significant difference between the pretest score (39.7) and posttest score (74.4) (p<0.05) with the N-gain value obtained was 0.56. This means that there is an increase in the medium category in students' concept mastery through RADEC learning.

Model pembelajaran RADEC berbasis STEAM pada materi sistem koloid mampu meningkatkan kemampuan berpikir kritis siswa

“…Berdasarkan beberapa permasalahan tentang sistem Pendidikan di Indonesia yang belum berjalan sesuai capaian pendidikan secara nasional, Dari permasalahan tersebut Sopandi (2017) menawarkan suatu model pembelajaran alternatif yang dinamakan Read, Answer, Discuss, Explain, and Create (RADEC) sebagai salah satu solusi dalam mengatasi rendahnya pemahaman konsep serta untuk mengembangkan kreativitas peserta didik. Model pembelajaran Read, Answer, Discuss, Explain, and Create (RADEC) merupakan model pembelajaran dengan tahapan membaca, menjawab, berdiskusi, menjelaskan, dan mencipta (Zulfa et al, 2021;Lestari et al, 2021;Pratama et al, 2020;Ritonga, 2021). Model pembelajaran RADEC lebih efektif dibandingkan dengan model pembelajaran inkuiri (Zulfa et al, 2021).…”
