GAMBARAN LEVEL SUBMIKROSKOPIK UNTUK MENUNJUKKAN PEMAHAMAN KONSEP SISWA PADA MATERI PERSAMAAN KIMIA DAN STOIKIOMETRI

Abstract

Submicro diagrams can be used as an assessment to determine the understanding of chemical concepts. Students can visualize a concept and develop a mental model for the concept through the submicro diagrams. The purpose of this study was to get submicroscopic level description that shows students understanding to chemical equations and stoichiometry. This research used descriptive method. The subjects were 10 grade high school students in Bandung. The research instrument is a diagnostic test of concepts understanding that involve the use of submicro diagrams. The results of diagnostic tests shows that only a small percentage of students are categorized in the level of understanding of concepts. While the rest are scattered into the level understand the concepts partially, understand the concepts with specific misconceptions, misconceptions and do not understand the concept. Students did not have full understanding of the concepts and misconceptions is due to weakness ability of students to interpreting the explanation of symbolic form into the submicro diagram model and vice versa.
