I took the survey they sent to teachers to ask how many points (out of 7) would represent a "5" on a certain problem. I'm guessing a lot of teachers said 5 points, because 5/7 approximately equals 71%. If 4/7 had been the majority answer, that would work out to about 57%--maybe not so coincidentally close to where a 4 ended up. In anything resembling a normal world, the cutoff for a 5 on this exam should have been somewhere in the middle between 57% and 71%, but the College Board's survey was only out of 7 points, and it didn't leave an option for 4.5/7 as a score. For all the grading philosophy we can talk about, this might just be a case of Occam's Razor, and the College Board didn't make their survey adequately precise.Willnoreply@blogger.comtag:blogger.com,1999:blog-5088860151651047897.post-53664679047942983962016-01-26T17:19:18.160-05:002016-01-26T17:19:18.160-05:00Thanks for the insightful analysis.
