Cheryl,
I'm thrilled this is relevant to your current teaching situation. Massey has a lot to say about the topic. And, you are right, assuming and generalizing many times just get us into trouble. Each class is made up of different students and we have to find out who they are to effectively reach them. . .where they are.
Thanks for the "link" to Massey where we can go look up more information on the subject. Nice job.
