Project-based Collaborative Learning Of Software Patterns

Project-based Collaborative Learning of Software Patterns Zoran Jeremić Military academy, Belgrade

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 2

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 3

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

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

5

Learning Scenario

6

LOCO-Cite Ontology  Learning Object Context Ontology (LOCO)

7

Domain Ontology

8

DEPTHS Architecture

9

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 10

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

11

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 12
