Hi
We have had various cheats with ifats
We do large classes.....typically 25-35 teams of six in their lecture theatres
Cheat 1: really bright laser pointers can actually see through opaque ifat coating...followed red dot on ceiling back to offending group...that happen 7 years ago...no repeats
Cheat 2: students were using a really fine pin to slighty score the opaque coating across all distractors to find star...one team about 5 years ago....no repeats
Cheat 3: in tiered lecture theatres ifat forms are big enough that nearby team can pretty easily see another teams form...we now ask teams to turn over forms when not scratching and we spend more time circulating around watching
NOT a Cheat 4: we had a team that part way down an ifat form started to only scratch off coating only over star....we assumed it was cheating (since scratch looked so precise and calculated)....but actually turned out to be the intersection of a particular pattern getting handed to a left hand scratcher....it took awhile to figure this one out...and it wasn't until the instructor tried scrtching with his left hand we figured this out
My big advice....don't stand at the front for the team test...keep moving around and watching....it also probably send a message to students is so important thst the instructor is paying attention :-)
