Kim Shankman, Benedictine College
I have students write their name (the way they want to be addressed, formal or nickname) on an index card the first day of class. I use these to take attendance, but more importantly, I shuffle the cards and use them as my method for choosing students to answer questions. That way they all know that the process is random, I don't have to deal with the deer in the headlights ("please please don't call on me") looks scanning the class choosing someone to call on, and I also am not tempted to rely on the same group of "old reliables" (generally prepared students) to answer questions.
