  1. Embedded Systems – Shape the World • What is it? • Education • Transformational • Substantial lab component • Global, outreach • Based on a freshman class • Peer to peer learning • What isn’t it? • For college credit • Profitable • Qualitative 41,329 students, 8% finished ½ 1 Valvano, Yerraballi, Fulton, and Dattathri

  2. Substantial Lab Component (90% grade) • Necessary Components – A sandbox for students to discover – Controllableby the virtual TA – Observable/gradable by the virtual TA • Lab Kit – Low cost ($35) – Readily available • Peer-to-peer interaction – Supports learning (see, do, teach) – Provides scaling We graded function not style 2 Valvano, Yerraballi, Fulton, and Dattathri

  3. Lab Kit • Board • Mechanicals • Electricals • Display (optional) 3 Valvano, Yerraballi, Fulton, and Dattathri

  4. Lab Kit • Low cost • Available–element-14 – Digikey – Mouser • Easy to buy This effort was only possible with support from Texas Instruments http://edx-org-utaustinx.s3.amazonaws.com/UT601x/worldwide.html 4 Valvano, Yerraballi, Fulton, and Dattathri

  5. Lab Kit • Low cost • Available • Regional http://aliatron.pt/e-biz/product_info.php/products_id/1469 5 Valvano, Yerraballi, Fulton, and Dattathri

  6. Educational Components • edX platform • Electronic textbook in html5, optional print textbook • 5 to 10 minute videos on YouTube • JavaScript animations • Quizzes • TExaS simulation grader • Written as DLL using MFC • Plugs into commercial-grade Keil uVision IDE • Interactive virtual TA • TExaS real-board grader • Embedded grader code along side student solution • Voltmeter, oscilloscope http://youtu.be/MUL3QNRy_LE simulation http://youtu.be/JYKvC6p8yl0 scope http://youtu.be/7jFpGsn18fA real board We graded function not style 6 Valvano, Yerraballi, Fulton, and Dattathri

  13. World Wide Reach Male 94%Female 6% • Language – In English – Needs multi-language – Had captions in English • Lab Kit – Cost – Availability • Internet Speed – Needs multiple resolutions – Ability to download then watch 13 Valvano, Yerraballi, Fulton, and Dattathri

  14. Results, 16-week class • 41,329 enrolled • 6925 students got a kit • 1200 paid $50 • 741 students got 100% • 6.4% completed 70% • 8% completed 50% • Physical lab increased success • 2/3 who started, finished • 91% approval rate • Most students worked alone 14 Valvano, Yerraballi, Fulton, and Dattathri

  15. Survey results (1190 responses)

  16. My Thoughts • MOOC Lab needs ability to control, observe, assess • Needs more creativity and open ended • Needs more qualitative assessments • Peer interactions are critical • Teams of 2 or 3 • Helping each other in forums • Cohort of 20 to provide qualitative feedback • Industry collaboration is essential • Can’t do enough beta-testing • It’s education but not ready for college credit • It takes a village Can you be lonely in a class of 40,000? 16 Valvano, Yerraballi, Fulton, and Dattathri
