Should concept maps be scored numerically?

After reviewing the uses made of concept maps in research, as an aid to instruction and as a form of assessment, the problems of scoring maps objectively are discussed. Maps created de novo by 15‐16 year‐old pupils, before and after their introduction to Mendelian genetics, are used to investigate the properties of a scoring system based on that developed by Novak et al. (1983). The maps have been scored separately for a number of features ('branching’, ‘general to specific’, ‘closed units’, ‘terminology’, ‘relationships’ and ‘ hierarchy ‘) and compared with performance on genetics examination‐type questions. The components are not all independent, and do not have strong relationships with performance. The limitations of analytic methods of scoring concept maps are discussed.
