Analysis of Students Understanding of Chemical Bonds Concept Using Three Tier Multiple Choice

Abstract

Diagnostic tests are needed to determine student weaknesses and can be used as a basis for follow-up with appropriate treatment. One type of diagnostic test is a three tier multiple choice. This study aims to analyze the level of students understanding of chemical bonding material. The method used is descriptive with the research subjects of chemistry education students totaling 93 people. Data collection with 14 test questions three tier multiple choice and analysis of students level of understanding using the technique Certainty of Responses Index (CRI). The results showed very low understanding of the chemical bond concept namely 29.50% and 62.77% misconception high category. The use of three tier multiple choice with the CRI technique is able to classify students conceptual understanding.
