This document proposes a framework called DEPTHS to support collaborative learning of software design patterns. DEPTHS would integrate various tools used for learning patterns into a single semantic framework. This would allow exchange of data about learning activities between tools and provide context-aware, personalized learning services. The framework would use ontologies like LOCO to share knowledge about learning objects, domains, and activities. DEPTHS would include a course management system, project tools, annotation tools, and online repositories to support collaborative work and feedback. The goal is to improve students' learning effectiveness and efficiency through a more integrated approach.

1. Project-based Collaborative Learning of Software Patterns Zoran Jeremi ć Military academy, Belgrade

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. 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

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

6. Learning Scenario

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

8. Domain Ontology

9. DEPTHS Architecture

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

11. Implementation of DEPTHS Feedback provision tools for educators LOCO-Analyst Online repositories Wikipedia, Yahoo! Design Pattern, Library, Portland Pattern Repository,Hillside.net Pattern Catalog… KIM framework – semantic annotation platform

12. Conclusion 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 Knowledge reuse Teachers spent less time developing online lessons Evaluation has been done at Military academy
