The document proposes DEPTHS (DEsign Patterns Teaching Help System), a semantic-rich framework for collaboratively learning software design patterns. DEPTHS integrates various tools for learning patterns through a shared semantic foundation. This allows students to exchange learning activities and resources across tools. DEPTHS maps tools and content to ontologies to enable context-aware and personalized learning services. The goal is an integrative environment that improves learning effectiveness and efficiency through recommendation and ubiquitous knowledge sharing.

2. Introduction Background Design patterns are recurring solutions to software design problems Found again and again in real-world application development DP are increasingly important in SE education Needs Learning at the pace and in a place that best fits Experiencing patterns-based software development In the context of real-world problems

3. High-quality learning of software patterns Needs (cont’d) Collaborative tools Forums, chat, and tools for software artifacts exchange Online repositories of software patterns and communities of practice Don’t be isolated from software professionals! Feedback for teachers about learning activities and the use of learning content Goal Integrative and open collaborative framework for learning design patterns

4. Outline Current state Proposed approach DEsign Patterns Teaching Help System Semantic foundation DEPTHS architecture and implementation Conclusion

5. Current State Current learning support Individual use of tools Lack of means for enabling the exchange of data about the activities between tools Poor support for Context-aware learning services Inter-tool personalized learning

6. Proposal: DEPTHS DEsign Patterns Teaching Help System Semantic-rich framework: Sharing knowledge

7. Learning Scenario

8. LOCO-Cite Ontology Learning Object Context Ontology (LOCO)

9. Domain Ontology

10. DEPTHS Architecture

11. Implementation of DEPTHS Course Management System – Moodle Moodle – LOC mapping Sesame repository OATS (Open Annotation and Tagging System) Educational services Domain modeling tool – ArgoUML ArgoUML – LOC mapping Collaborative work support Educational services

12. Implementation of DEPTHS Feedback provision tools for educators LOCO-Analyst Online repositories Semantic annotation of patterns at Yahoo! Design Pattern, Library, Portland Pattern Repository, and Hillside.net Pattern Catalog

13. Conclusion Integrative collaborative learning environment DEPTHS Benefits Students’ learning effectiveness and efficiency Recommending resources from online repositories related to the learning goal Integration of knowledge about all related learning activities Performed by any student with any tool User-centered and ubiquitous knowledge sharing Extensive evaluation to be done
