Abstract

A characteristic feature of physics knowledge is the high degree of coherence and connectedness of its concepts. To large degree physics concepts and laws can be viewed as organized, network-like structures. Consequently, learning can also be seen as the working with and the building of the conceptual networks. It is argued here that a useful viewpoint on learning physics conceptual structure can be developed on the basis that physics concepts can be seen as networks, where the formation of such structures is guided by the meaning coherence of concepts, related to the deductive coherence of concepts themselves and their explanatory coherence with respect to experiments. Fr om this viewpoint, we compare here how experts and novices represent their physics knowledge by drawing concept maps of such networks. By analyzing the topological structure of the concept maps it is shown that experts’ maps are characterized by conceptual coherence and hierarchies inbuilt in the network-structures. In novices’ concept maps similar features are found in the best cases, but many novices produce maps with poor coherence and a lack of organizing hierarchy. Finally, applications and advantages of the viewpoint emphasizing networked structure of concepts in physics teacher education are discussed.
