Abstract
This research is based on writer’s previous misconceptions research on chemical bonding. The study aims to calculate the percentage of misconceptions and misconceptions types about chemical bonding. The method used is descriptive. Samples used in this study was 75 students in college. Data collection tool used in this study was an online modified two-tier diagnostic test. The results showed that types of student misconceptions occur in sub concept: determining the type of bonding of a compound based on the difference in electronegativity, determine the type of bonding may occur if the metal and non-metal bind together and determine two examples of ion or covalent bond compounds.
Highlights
Chemistry is one of the subjects must be taught in natural science program in Senior High School in Indonesia
Based on the ministerial decree of the ministry of education and culture about the national education system, the purpose of learning chemistry is to make the student understand about chemistry concepts and apply it to solve the problem in real life and in science and technology life
Application of chemistry in real life start with an understanding of chemistry concepts, principles, laws, and theories
Summary
The knowledge level chemistry subject in senior high school can be categorized into three types, that is sub-microscopic (abstract and cannot detectable with ears, eyes, noses, tongue, and skin), macroscopic (can be detectable with our body’s instrument) and symbolic (a symbol represents a chemistry formula or subject) [2-4] The complexity of this subject one of cause the misconception happened in chemical bonding [5]. Misconception in a student can be detected using various detection instruments It includes interview [53-55], open reasoning [56-57], and multiple choice [58-59]. The second tier is certainty of subjects’ reason after answering the option that includes “Yes” for certain answer and “No” for the uncertain question These questions were developed from previous research about the certainty of response index [62] and multiple-tiered [63].
