The Effect of Cognitive Conflict Strategy to Chemical Conceptual Change

This study aims to determine the effect of cognitive conflict strategy on the chemical conceptual changes of students on the acid-base material. The sample used is 51 students. We developed a two-tier diagnostic test instrument to test students' level of understanding. The data obtained were analyzed quantitatively and qualitatively. The results of the analysis provide a description of the misunderstanding profile of students, where before treatment there was a misunderstanding of the concept, but after being given treatment with cognitive conflict strategy, the level of misunderstanding of students decreased. Different tests on the pre and post test scores indicate that there has been a conceptual change. Based on the results, it is concluded that cognitive conflict strategies have an effect on the students' conceptual changes.
