1 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 Valvano, Yerraballi, Fulton, and Dattathri 41,329 students, 8% finished ½ 1

2 2 Substantial Lab Component (90% grade) Necessary Components – A sandbox for students to discover – Controllable by 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 Valvano, Yerraballi, Fulton, and Dattathri We graded function not style 2

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

4 4 Lab Kit Valvano, Yerraballi, Fulton, and Dattathri Low cost Available – element-14 – Digikey – Mouser Easy to buy This effort was only possible with support from Texas Instruments 4

5 5 Lab Kit Valvano, Yerraballi, Fulton, and Dattathri Low cost Available Regional 5

6 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 Valvano, Yerraballi, Fulton, and Dattathri simulation scope real board We graded function not style 6

15 Survey results (1190 responses) 15

16 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 Valvano, Yerraballi, Fulton, and Dattathri Can you be lonely in a class of 40,000? 16
