Description
Summary:In the last few decades, research has shown that chemical bonding is a difficult concept for students that can lead to misconceptions. The purpose of this research is to know the misconceptions and threshold concept in chemical bonding from various research studies and teacher experiences. This study uses a qualitative method including document analysis which mostly the journal articles which presented research studies about misconceptions. Beside, this study also conducted a clinical interview with three chemistry teachers to get information from a real practice. Based on the analysis of the journal, the book and the interview with chemistry teachers, there are a frequent misconceptions of the chemical bonding such as: ionic bonding was sharing electron; there is a transfer of electrons in covalent bonding; the atoms of Na and Cl attract each other and form NaCl; covalent bonding have very different electronegativity; equal sharing of the electron pair occurs in all covalent bonding; and metallic bonding was a transfer of electron. Meanwhile, the threshold concepts for chemical bonding are periodic properties of the elements, electron configuration, and metal/non-metal/metalloid.
