The Research On Quality Control Of Multimedia Teaching Materials Based On CMMI

Multimedia Learning Contents (MLCs)become popular and quality of it is also becoming important. But most of them focus on content quality, few taking care on its production process quality issues. The Multimedia courseware with the constituents of Content and Software are obligated not only to fulfill SCORM standard, but fundamental theory of Software Engineering as well as International standards of quality assurance. Along with high-quality requirement, creating low-cost and high-efficiency products are the major topics for long in the field of Multimedia Learning Content Creation. This study wishes to focus on process control issues of MLCs. We want to use Graph theories to help reducing errors happening during MLCs producing.This study defines a new term'MLCs Directed Graph (MDG)', and takes care on those materials of MLCs and builds relations on materials to MLCs or materials. With this MDG, we could find and define MLCs quality defection issues, finding samples of those issues, and prevent form happening of these issues by using graph and graph mythologies. And this will improve the quality of MLCs by reducing defection issues. This study concludes7defection issues:(1) Materials in chaos and without management. MDG could build a structure of materials and easy to management.(2) With edge relations and MDG, it is easier to check the correction of materials.(3) Integrity of materials of MLCs or logical organizations could be checked easily and systematically.(4) When changes happen, side affections could be evaluated easily by reviewing nodes related.(5) Unused nodes could be noted by MDG.(6) Lacking material nodes check by MDG at design time.(7) Extra group relation defined between nodes helps node group relation examinations.
