Abstract

In this paper, we present a teaching experience conducted with 15-16 years-old students. They were asked to produce analogies to explain the formation of a chemical bond and to criticise them from the consideration of their positive and negative parts. By analysing the students answers, the teacher realised some of their difficulties in understanding chemical bonds that had not been identified before. Therefore, she could change the teaching in an attempt to discuss the central aspects of the students difficulties.
