You said crystal ? I think glass
Our objective is to take account of student understandings in the teaching of geology to 14 years’ old pupils. A large part of our course is organised around the four concepts represented by the words crystal, rock, magma and earth. The present article covers students’ conceptions that we have collected. We describe them using the same modalities as were used to collect these conceptions. They are then related to different formulations, organised into a network, of linked concepts. The aim of this presentation is to relate the conceptions of students, the obstacles that have been spotted and the possibilities of overcoming them.
