Student learning of new concepts requires connecting the new concept to old learning. Understanding grows as layers are added through connections to old ideas, and deepens as old ideas are rearranged through sudden insights.
This process can be made more explicit by using concept maps—a graphical representation, like an organizational chart, of a central idea.
To build a concept map for a particular topic, the creator identifies a central idea or focus question for the map. After recording as many ideas that fall within the focus question as possible, he or she then orders them approximately from the most inclusive to the most specific concept. Finally, he or she arranges these associated ideas in a meaningful way on his/her map to show relationship hierarchies, drawing in various types of links, such as solid lines for strongly connected ideas, dotted lines for weaker ideas, a line with a slash mark on it for opposites, etc. The system doesn’t matter so much as that it is individualized by the student to represent his or her construction of that concept. And it is a map “in progress”. Rather than being “finished” it evolves with the students’ understanding.
Concept maps are particularly powerful in illustrating a student’s understanding of relationship and interconnectedness. They can immediately reveal misperceptions.
Students may have difficulty at first creating something that requires so much active thought, but with practice and encouragement they can improve. They may have particular difficulty understanding or making explicit relationships between different concepts. They may feel everything is related to everything, but their task is to choose the most salient/important links.
Creating a concept map for a chapter is a great way to study once the process has been practiced and understood. Creating an accurate concept map does require some understanding of the material so you would probably use them in the middle to end of a topic, rather than at the beginning (unless you want to do a pre-post comparison).
