Notes 20100416.120312 Guest Lecture Clickers
From SnOwy - Ed's Wiki Notebook
Clickers
- clickers used at Waterloo [1]
- different kinds - iClicker, eInstructions
- sophisticated ones that can store numbers, phrases and do math
- the cheaper ones are just for multiple choice
- current ones used are iClickers, we will eventually switch to cell phones anyway
- addresses a few challenges: pragmatism, social (shyness), other instructional challenges for students' learning
- attrition [2]
- possible to revote-- if the question is still open, it's the last click that counts
Problems and MY FIXES :P
- serial number registration problem: use an at purchase and at registration checksum or have a simple serial checksum that's not provided to the student
- cheating -- operating at 915MHz, these clickers readily interact with the nitrogen in the air; use two receivers to triangulate each clickers' location based on signal decay
