For those of us without a scanner, I do the following to get a sense in the classroom which questions they had difficulty with (it is also something of a "sponge activity" as it can take variable amounts of time). After teams finish their team RATS, I ask each team which questions they still don't understand (and add that they can explain the others). After all teams are done, I have each report out the ones they don't understand and either I or another team fills them in. This seems to fit into TBL "spirit" of getting quick feedback as well as helping build teamwork. I think I got this idea here... - Bill Jim said: > we run item analysis on the whole cohort since our scanner pumps out > discrimination, point bi-serial and p-value > > I don't see any problem with using only 10% of the group either > > jim > > > On Fri, Nov 30, 2012 at 8:13 AM, Jenny Morris > <[log in to unmask]>wrote: > > > Dear All**** > > > > ** ** > > > > As this is the first time we have been using TBL I plan to run an item > > analysis on the questions we are using.
