Terri: Students do form opinions, often quickly (fairly or not), and that opinion colors how they will approach the class in general. Now, I think we can be prepared but lousy at delivery, which is similar, but a different topic. But if the teacher plans the lesson well, gets the resources and materials ready, assures media resources are available (classroom ready, internet working, LCD operable), books accessible, white board clean, etc., these set the tone for a well delivered class. Students will learn to expect that's the expectation for the class and will prepare appropriately. Regards, Barry
