This paper presents a framework for the evaluation of concept maps. We focus on supporting the student in dealing with ill-structured and complex problems. We argue that these problems require the application of "the modularity approach." In view of this, the paper describes ways of providing student support for the implementation of this approach within the context of a concept mapping activity. As a basis we make use findings from the field of brain science and mathematical concepts and tools from the field of network theory, in order to present specific evaluation methods, the further development of which we consider extremely promising.
