Hi Lora,
I don't think professors worried about such things either when I was in school. They always started their first lecture with the "look to your left now look to your right" speech to spook us. Because when we looked left and right and was told that those people would not pass the course it really set the stage for feeling comfortable. We were scared to death. Fortunately I was one of those that survived those speeches but I was plenty scared that on any given day my number would be up and I would flunk the course. These were classes of 300-600 students so the fear factor was even higher.
I agree with you that with the smaller classes students really look for acceptance by the instructor and fellow students. I work very hard in my classes to make sure each students feels accepted and can find success if he/she is willing to put for the effort required.
