From ‘ecologist’ to ‘conceptual ecologist’: the utility of the conceptual ecology analogy for teachers of biology

This paper advocates the application of established teaching models to the professional development of biology teachers. This is achieved by using the analogy of conceptual ecologies, made explicit through concept mapping. The approach is designed to support teachers' developing understanding of pupils' conceptual change by using familiar terminology and biological analogies. Monitoring of students' understanding at an ecosystemic level may also help distinguish between instances of conceptual change and contextual switching (described here with reference to photosynthesis).
