Oh, the Irony.....
Students chit-chat amongst themselves during lecture Get annoyed at me when they don't understand the material
That is their own dang fault. They are paying for the class and can choose to learn or not, and it isn't the profs problem. That is how I view my future teaching job. Along with a side of if my lecture is too boring and they resort to Facebook or friends, then I should update my teaching a little.
