Scott, I am wondering what scanner technology you have been using? This is one of the challenges with using this approach, on finding out, during class which questions/concepts are creating problems for the students. Being able to scan a score sheet, immediately, sounds like the way to go (doing it while the Teams are working through the one- IF AT each team fills out).
We have experimented with sampling... in a class of 48-students this semester, randomly pulling out a 25% sample of the score sheets (which we had made-up, using the "allocation of 4-points" for the case of 4-possible answers, approach) they turn in before they go into the Team/IF AT part of the exercise. Then, we hand grade those 12-score sheets, using clear plastic overlays... having TA help here.. and then "lecture" only on what the sample of 12 suggests are problem areas. This works to the extent the sample is representative... but I would prefer having a scanner in class to see how all 48-students handled the questions. Also, grading 48-score sheets by plastic overlay/by hand is tedious at best! (Also, I am assuming the scanner technology you are using also associates the name with the score? Data (grades/score) management for upwards of 10 or more RATs X 48 students, plus 10 X 8 Team RATs a semester is a nightmare!
Thank you for any help you can provide in this matter.
