A Semantic-rich Framework for Learning Software Patterns
0 likes393 views
The document proposes DEPTHS (DEsign Patterns Teaching Help System), a framework to improve teaching and learning of software design patterns. It integrates existing learning tools and systems using an ontology to capture learning context data. This allows for personalized, context-aware recommendations and collaboration. The framework leverages existing open-source tools like Moodle and ArgoUML, annotates content using KIM, and represents learning contexts using the LOCO ontology. Future work includes further developing and testing DEPTHS and conducting user studies.

- 2. Introduction Research Focus software engineering education teaching & learning software Design Patterns (DPs) DPs are successful solutions to recurring problems in software design October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 3. Introduction The requirements: Learning at the pace and in a place that best fits Experiencing patterns-based software development applying the theory in the context of real-world problems Experiencing collaborative software development forums, chat, and tools for software artifacts exchange Right-in-time access to the relevant online resources online repositories of software patterns and communities of practice Feedback provisioning October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 4. Introduction The Goal Improve the process of teaching/learning DPs thorough provision of context-aware learning services The Approach A comprehensive, semantic-rich framework for collaborative learning of software DPs October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 5. Outline Current state in teaching/learning DPs Proposed approach DEsign Patterns Teaching Help System (DEPTHS) Semantic foundation of DEPTHS DEPTHS architecture and implementation Conclusions October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 6. Current state in teaching/learning DPs Individual use of software systems/tools ‘ Fragmented’ approach lack of means for exchanging data about students activities among different system/tools The major drawback: poor support for context-aware learning services inter-tool personalized learning October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 7. The Proposed Approach DEsign Patterns Teaching Help System – DEPTHS a comprehensive learning framework that supports collaborative learning of software DPs integrates diverse systems, tools and services that students interact with LOCO ontological framework as a base for integration October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 8. The Proposed Approach Examples of DEPTHS functionalities: context-aware retrieval & recommendations of: DP resources from online repositories learning artifacts produced and shared by peers software projects, discussion threads, chats, … other students, experts and/or teachers to offer help in the given situation
- 9. Semantic foundation of DEPTHS Learning Object Context Ontology (LOCO) ontological framework In DEPTHS, LOCO is leveraged for: capturing, representation and integration of learning context data from all systems, tools, services semantic annotation and interlinking of digital resources an ontology of DPs, developed by (Henninger, 2007), reused as the domain ontology October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 10. DEPTHS architecture October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 11. Implementation of DEPTHS Learning Management System – Moodle The rational: popular, free, open-source LMS, based on the social constructivist theory Moodle interaction data –> LOC mapping D2RQ Sesame Java API Educational services context-aware recommendation of resources October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 12. Implementation of DEPTHS Domain modeling tool – ArgoUML open-source software modeling tool uses open software standards allows for exchange of software artifacts ArgoUML interaction data –> LOC mapping Collaborative work support Educational services E.g. suggesting solutions to similar problems October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 13. Implementation of DEPTHS Semantic annotation of learning content using the services of the KIM platform allows for semantic interlinking of diverse kinds of learning artefacts E.g., online resources, students software models, and exchanges messages Feedback provision tools for educators LOCO-Analyst October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 14. Conclusions The suggested approach: Integration of existing, proven learning systems and tools into a context-aware collaborative learning environment by leveraging a flexible ontology-based model of interaction (i.e. learning context) data Benefits: Integration of knowledge about learning activities performed by any student with any tool Context-aware recommendation of resources Relevant content from online repositories Peers help October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
- 15. Conclusions Future work: Further development and testing of DEPTHS User evaluation studies October 18, 2009 EC-TEL2008, Maastricht, The Netherlands
