2. 2 outline Introduction Architecture of TMDC Experiment and Results Conclusions

3. 3 Introduction_1/4 Purpose  Reusing e-material from different providers and integrating them for a particular course  Semantic metadata, following the SCORM Content Aggregation Model Searching method  For document Keyword search Full text search  For content Ontology search Thesaurus search

4. 4 Introduction_2/4 SCORM_1/2  Sharable Content Object Reference Model  characteristics: Accessibility, Interoperability, Durability, Reusability

5. 5 Introduction_3/4 SCORM_2/2  Content Aggregation Model: like content structure

6. 6 Introduction_4/4 Ontology  Classes  Properties  Individuals/Instances

7. 7 Architecture of TMDC_1/5 TMDC: Teaching-Material Design Center Four module  Teaching material repository module  Course database module  Ontology module  Course authoring module

8. 8 Architecture of TMDC_2/5 Teaching material repository module  preserves and manages learning objects Course database module  preserves the teaching material structure that has been developed

9. 9 Architecture of TMDC_3/5 Ontology module_1/2  2 ontologies course ontology: describe the term relations among course topics

10. 10 Architecture of TMDC_4/5 Ontology module_2/2  2 ontologies content ontology: describes the relations among learning objects in a material

11. 11 Architecture of TMDC_5/5 Course authoring module  Step 1: Select course domain.  Step 2: Describe the goal of teaching material.  Step 3: Refer to similar courses.  Step 4: Choose the course table of contents.  Step 5: Design the teaching template.  Step 6: Confirm the course outline.  Step 7: Choose the content of teaching material.  Step 8: Revise the content.

12. 12 Experiment and Results 1/4 Participants  30 postgraduate students who had been section tutors of the “Network Management” course  used the TDMC system to design teaching material and compared it with the method they had used
