Semantic integration of learning objects for UREKA navigation & integration toolkit - UNIT

Now a day, education is getting more expensive, relative to other fields. The reason for such increasingly expensive field is due to less investment and efforts to involve information technology. There is a need to develop new and effective models for learning through information technology. The key component for such learning models is learning object, which includes different types of media i.e. audio, video, image. text etc. A lecture is a combination of one or more learning objects. Thus efficient and effective integration of learning objects becomes the key part of this activity. UNIT (UREKA navigation and integration toolkit) is emerging model for such type of integration. It defines CMF (common media framework) that has a predefined schema for integration of learning objects, and also the capability of handling spatial und temporal behavior for learning activity separately. Furthermore, it allows users to modify these behaviors and to attach presentational templates of their own comfort that provide reusability of both the integrated information and templates. The integration information in CMF file will be combined with loosely hounded presentational templates, dynamically to generate presentation for learning activity (A Lecture).
