2. Collaborative learning in design
Goals
Develop an infrastructure that supports effective knowledge management for student design teams
Assist members of design teams to build and retain knowledge created through discussions, project documents and sharing of artifacts

3. Common Issues in Design Teams
Knowledge sharing
Information retrieval

4. Background Concept Mapping in Design Education Scientometrics

5. Capturing in-process data
We have 6 years of data from project classes that used the Kiva for team collaboration
Combines functions of , bboards and chat
Each year’s Kiva has hundreds of threads and thousands of posts and files

7. Approach
DesignWebs
synthesize the design knowledge from multiple sources of information used by students during a design project
enable users to see connections between the concepts used in an artifact at different levels
can reveal the current state of the project and the underlying structure of the design
DETC

8. Approach Seed the DesignWeb with research papers
Extract the LDA model and apply hierarchical clustering to extract a hierarchical topic structure
Calculate connections between topics and terms
Make relevant documents accessible
Generate the web-based navigable DesignWebs

9. DesignWebs Scenario Civil Engineering Junior Projects Class
One year, a student team worked on stormwater management solutions to address drainage issues in sections of the parking area on campus
They performed site analysis, evaluated alternative solutions and made recommendations and made full schematic designs
Next year, a new team of students took on the project of water recycling to prevent stormwater discharge from mixing with the city sewer system.

15. Challenges Segment resolution Levels of abstraction
Students are novices in technical writing
Alternate views for different users
Credibility of source
Identifying the structure of created knowledge, especially for different versions of the same document

16. Research Questions
Can we automatically extract the concept maps of a design artifact from the group conversation and documents for ongoing and archived project corpuses?
Can we automatically detect the inception and connectivity of key ideas in groups at various project milestones?
Can we identify evidence of favorable design performance for a group from the vocabulary used in its conversations and documentation?
