1) The document discusses a framework called DEPTHS that aims to support semantically-enabled project-based collaborative learning of software design patterns. 2) DEPTHS integrates tools like Moodle and ArgoUML and connects them to ontologies to provide context-aware and proactive support for collaborative learning activities. 3) An evaluation of DEPTHS with 13 students found that it was generally more effective for learning design patterns than traditional methods and that integrated tools and access to resources improved learning.

10. Evaluation Performed in February 2009 University of Belgrade with 13 students Perceived effectiveness of DEPTHS for learning DPs effectiveness of project-based learning approach usefulness of integrated tools usefulness of access to relevant resources and sharing of information affects learning

11. Evaluation Students’ perception of learning with DEPTHS Comparing to traditional learning Usefulness of integrated tools and services 30.77% reported technical problems 30.77% 53.85% 15.38% 0% More effective Same Less effective Not very useful 38.46% 46.15% 15.38% 0.00% 0.00% Peer finding 46.15% 69.23% 15.38% 4 30.77% 15.38% 7.69% 0.00% Brainstorming 15.38% 15.38% 0.00% 0.00% Internal content finding 76.92% 7.69% 0.00% 0.00% Web resource finding 5 3 2 1
