Concept maps are organisations and visual representations of knowledge. They show the relationships between concepts or ideas, or rather in the case of language learning, between the lexical items that you have chosen. Each word or phrase has a shape drawn around it, and then the shapes are joined with arrows. The nature of the link is often written on the arrow.
Concept mapping obliges students to think about the characteristics of a word or phrase and how it might be related to other words or phrases. Like with the other Thinking Skills strategies mentioned, it is intended to go beyond just the meaning of the word and requires students to use grammatical terminology to explain and justify the links that they have made. It has elements of both classification and odd one out in that students are looking for the links between words.
Concept mapping is ideal for pair or group work, and is useful for checking students' understanding of grammar and structure, and any misunderstandings they might have.
