I learn a great deal from the results of RATs. 1. I can identify things to talk about in the absence of questions. 2. Students make a lot of notational errors. I can mention them and ask them to use notation correctly. I usually point out that these errors are in the same class as poor grammar. No one can understand anyone who doesn't use good written English. 3. I can identify things to emphasize in my mini-lecture next year. 4. I can identify potential exam questions. Sometimes these are identical to the RAT questions. I tell everyone this. 5. I can identify individuals who are not doing their readings consistently or carefully. Regards, David Smith David W.
