The wiki can be used as a semantic networking tool, a way to construct meaningful connections between topics, ideas or concepts. A semantic network is composed of nodes (such as wiki pages ) with meaningful links (hyperlinks) connecting them. A semantic network of wikis can help learners to organize their ideas and to convey that organisation of ideas to others (Jonassen et al, 1999, p.165)

Mind tools are computer-based tools and learning environments that have been adapted or developed to function as intellectual partners with the learner in order to engage and facilitate critical thinking and higher order learning. (Jonassen, 2000, p.9)
