Introduction

Background

Design patterns are recurring solutions to

software design problems

• Found again and again inreal-world application development

DP are increasingly important in SE education

Needs

Learning at the pace and in a place that best fitsExperiencing patterns-based software development

• In the context of real-world problems

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 contentGoal

Integrative and open collaborative framework for 

learning design patterns

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

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
