No Formal Workflow Today
Our Plan: Overall
1. Mine the Gems • Find the Gems
• Seed Gems
• Harvest/Prune
• Test/enrich MIT
2. Build the Necklaces • String of Gems
• Offer courses: • MITx
• edX
Extensive Research Effort: ☞ Over 30 professors identified • 6-10 research directions • Over 20 existing efforts • 3 Schools (working on other 2) • Funded experiments Execution strategy
Stir & Repeat
Establish Workflow: • Hire staff rapidly • Understand needs
• Video • Interactive exercises
• Train and scale Crank the engine
Build Factory
Mining the Gems
• Vignettes
• Simulations
• Virtual Labs
• Home kits
• Gaming
• Evaluation
• Authoring
• Graduate Program
Video Games!

Conclusions
• There’s a there here • Students on campus like MITx
• Students already using MITx
• How to merge into campus life being studied
• There’s a there there • SJSU experiment reveals advantages to exporting courseware
• Possible big impact on the world
• Open Source, Open Resources
