Hi again, I'm curious if anyone has had issues with students realizing that there are only a few versions of the IF-AT forms? That is, even if you switch versions of the forms from one RAT to the next, do students ever realize that the pattern of answers might be the same as an earlier form? My concern is that I will likely only have two versions of the form and students will take five or six RATs so there would have to be some repetition. I know I could get more versions by ordering more forms but in order to get all five different answer versions, I would have to order 1250 forms and it would take me YEARS to use them all - but is that what most people do? thanks, Jennifer **************************** Jennifer Imazeki Department of Economics San Diego State University homepage: http://www-rohan.sdsu.edu/~jimazeki/ Economics for Teachers blog: http://economicsforteachers.blogspot.com
