Scaffolding in Learning Cycle 5E, is it Effective or Not?

Abstract

Learning chemistry in the chemistry education study program has not maximized the scaffolding provision yet, so students still have difficulty in mastering the precondition concept. This study aims to determine the effectiveness of learning using the 5E learning cycle model assisted by scaffolding on acid and base material as seen from an increase in students' understanding of concepts. This research is a quasi-experiment with one group pretest-posttest design. The subjects of this study were 32 students who choose randomly from the chemical education study program class of 2019. The instrument used is an essay learning achievement test to measure students' understanding of acid and base concepts. The results showed that the n-gain value obtained is 0.31 or can be interpreted as an increase with moderate criteria. Therefore it can be concluded that the addition of scaffolding in the 5E learning cycle is effective to increase students' understanding on acid and base material.
