Özet:

The aim of this study is to investigate the definitions of university students related to the interactions among chemical species. Also, the effect of Inquiry Based Learning on those definitions has been searched in the study context. The study group consisted of first year Science Teaching (f=51) and Biology Teaching (f=21) students studying in one of the governmental universities in the west part of Turkey. A qualitative approach was utilized in the study. The students were requested to make definitions of nine concepts related to chemical interactions (chemical bond, ionic bond, dipole-dipole inreactions, covalent bond, hydrogen bond, ion-dipole interactions, metallic bond, Van der Waals interactions and induced dipole interactions). Data were collected in the form of pre and post tests and analyzed under four categories such as full correct, partially correct, incorrect and no response. As a result, it was identified that the definitions provided by the participants mostly improved due to teaching. Besides, several definitions (Van der Waals interactions, induced dipole interactions, dipole-dipole interactions) obtained from Biology Teaching students stayed in a restricted level despite teaching process. The study highlighted several points that should be considered by the chemistry educators during teaching as well as representing students' conceptions related to chemical interactions. Based on the study findings, it is recommended to utilize technological support such as animations during teaching of abstract concepts which students find difficult to understand.
