Challenges of Large Lectures
• Difficult to gauge students’ understanding and engagement
• Students hesitate to ask questions– Stall large class– Personal embarrassment
• No peer discourse– Lacking useful elaboration– Less engaging– Stern, anti-social atmosphere
![Page 4: SLE: Student Learning Environment Nathan Campbell Lisa Doan Kirill Kireyev Malte Winkler DLC 2006 Project](https://reader030.vdocuments.mx/reader030/viewer/2022032800/56649d4e5503460f94a2e0c1/html5/thumbnails/4.jpg)
Opportunities of Large Lectures
• Large lectures are prevalent and inevitable
• Can we positively exploit:– Large body of knowledge?– Diversity of opinions?– Teaching assistants?– Existing technologies (laptops)?

Clicker Question!
• Are clickers effective?
A. Yes – they help me gauge how much I’m learning

![Page 11: SLE: Student Learning Environment Nathan Campbell Lisa Doan Kirill Kireyev Malte Winkler DLC 2006 Project](https://reader030.vdocuments.mx/reader030/viewer/2022032800/56649d4e5503460f94a2e0c1/html5/thumbnails/11.jpg)
Technology Design Issues
• Balance online vs. face-to-face– How to integrate?
• Structured (WebCT) vs Unstructured (wiki)– Freedom may be messy, overwhelming
• General vs. specific• Mediation?• Support flexibility, evolution
– Users will use in different ways
• Sensitive to context, time
![Page 12: SLE: Student Learning Environment Nathan Campbell Lisa Doan Kirill Kireyev Malte Winkler DLC 2006 Project](https://reader030.vdocuments.mx/reader030/viewer/2022032800/56649d4e5503460f94a2e0c1/html5/thumbnails/12.jpg)
Making Collaboration Successful
• Shared motivations, common goals• Adequate incentives• Positive interdependence• Symmetry of ignorance
– Diversity of opinions, backgrounds
