Greg Galloway
Module Goals
– Introduce electrical and computer engineering
– Demonstrate the accessibility of engineering
• An arcane art?• Anyone can be an engineer if they try
– Demonstrate the engineering process• Problem solving techniques common to all
sciences
The Scheme of Things
OVERALL MODULE
THIS ACTIVITY
Logistics
• Divide class into groups of two• Groups assign a scribe and a calculator• Method of job selection
– Groups consider multiple jobs at a time• Two or three is sufficient
– Many jobs available• Jobs have varying difficulty• Decision process involved
List of Available Jobs
Example Job
Solution Sheet
P=45wV=120v
R=? P=VII=V/RP=V2/R
Ohm’s Law V=IRAnd
Power P=VIGiven to students
45=1202/ xx=1202/ 45R=320Ω
R=320Ω

Grading Modifications
• Groups can pay for perks• Check a solution
• Peace of mind• Balance
• Spy• Compare answers• Instructor does the spying
• Hint• Knowns/Unknowns
Other Possibilities
• Job List and Worksheets have multiple uses– Extra credit requests– Pop quizzes– Reinforce skills – Bonus activity
• This activity is a template– Also works for hands-on
• Design process, analysis, etc…
