1 Better Learning ECEDHA 2013 Clint Cole, Digilent

2 ECE Department Heads are the most important people in the world.

3 Engineering is Fun

4 We re starting early and building excitement

5 Introductory hands-on engineering classes are popular

6 But then Pack students in labs Make them perform assigned tasks in allotted time (follow the recipe) Equipment stays in lab; must learn its use while performing required tasks Incented to stay on task (work don t play), get done and leave De-incented to find and explore knowledge gaps (peer pressure) Repeat weekly

7 Are we suggesting... Obedience and conformity are valuable engineering skills? Engineering/creative processes are well quantified, with predefined end points? Design skill/success is measurable against an absolute scale? Real engineering tasks will occur in a similar sandbox?

8 And faculty must Schedule labs Ensure PCs work, or try to buy new ones Ensure CAD tools still run Ensure student accounts are up Ensure equipment still works Reorder books/manuals Find adequate TAs Find a way to employ adequate TAs Deal with issues

9 A better way.

10 Makers are Learners It s human nature to build, create, explore Give students design tools and they ll use them whether or not they re required Encourage students to explore, discover and build they will Incent students to make, guide their activities, encourage sound design methods, and build excitement, vitality, relevance, & fun

11 Active Learning Works Have students build lots of real systems Simulations are good, but end-points are models Physical projects invite curiosity & exploration Dwell when/where needed Learn self reliance, self confidence Learn to use modeling and simulation at same time The Key: Design kits students can use any time, any place, and at their own pace

12 Student Owned Kits: A New Standard Student with their own kits Learn more, learn faster, retain more Score higher on tests Complete more assignments Use fewer resources Enjoy their experience Supported by Studies published in proceedings of ASEE

13 Requirements 1. Low-cost, powerful, self-contained design kits 2. High-quality, freely posted, community supported projects, tutorials, examples, reference designs, etc. 3. On-line course/educative materials 4. Effective support

14 Powerful design kits every student can own
