To store knowledge content of course materials and to consider the dimensions of Bloom s factual conceptual and procedural knowledge this study developed a knowledge ontology as shown in Fig. 1. This knowledge ontology was developed by content analysis of specific chapters from the above textbook and includes the concepts of WordNet revised Bloom s Taxonomy Dublin Core Semantic Header and so on.

Course Material Knowledge Ontology Figure 1 uses the Knowledge Content to store the real course material content and comprises 12 subclasses of knowledge which are used to store knowledge concepts such as What Why When and How . For example sequence relation knowledge includes procedure the procedural step used to express the concept of How time the time sequence rank specific attribute rank . Hypernymy knowledge records a relation similar to generalization is-a relation is-a-kind-of. Meronymy knowledge records a relation similar to
