Overview
• Tagging Key and Promising Ideas
• Scaffolds
• Visualization
• Concurrent, embedded, and transformative assessment
Tagging Key and Promising Ideas Promising Ideas tool
Keywords
To Tag Promising Ideas?
• Promisingness evaluation (Bereiter & Scardamalia, 1993; Bereiter, 2002)
• A need to identify promising ideas
A case study on Grade 3s’ discourse
• Design-based research (Brown, 1992; Collins, 1992)
Promising Ideas tool
Identifying ideas:1. Click2. Choose a color3. Highlight an idea4. The idea gets highlighted and goes to the box
Promising Ideas toolPromising Ideas list:1. Promising ideas listed2. Choose a specific color list3. Number of hits4. Link backwards to notes
Pilot study 1: Grade 5/6 (Chen et al., 2011)
• 83 “promising ideas” from 207 notes

Pilot study 2: Grade 3
• Promisingness treatment module• “Progressive use”
– two iterations of “writing-tagging-exporting”• Preliminary results
– less facts/evidence– improved coverage of domain content

Scaffolds
Improve scaffoldsScaffold Tracker
Scaffold Tracker 1. Frequency of scaffold use2. Embellishment icons3. Dynamic filter4. Live update
Future directions
• “Dynamic promotion” of scaffolds
• Epistemic agency?
Concurrent, Embedded, and Transformative Assessment
Content ClassificationSemantic AnalysisCognitive Diagnostic Assessment
Automated detection of “ways of contributing”?• Content classification
• TagHelper (Rosé et al, 2008)
Automated detection of misconceptions?
• Misconceptions in KF– Healthcare (Lax et al., 2010)
• Semantic Analysis– Focus on predicates (Slotta et al., 1995, 2006)

Conclusion
• A single analysis or technique cannot do it
• Technology alone cannot do it
• Need for collaboration across teams
