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

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

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
