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
