Research on networked video courseware system based on object-oriented method

Networked video courseware(NVC) provides a new research perspective for resource development in education technology field by combining education technology and film arts knowledge. Teachers often have difficulty in fulfilling complex courseware designs due to the lack of sufficient film arts knowledge. This paper presents a systematic object-oriented knowledge modeling which is developed and described in Unified Modeling Language (UML) for NVC design by summarizing and analyzing the expertise, cognitive rules and practices of various video elements applied in teaching. In the NVC system model, associations between entities and the NVC template structure is discussed in detail. A case study is given to demonstrate the procedure of how the NVC knowledge is expressed.
