I am a first time instructor, and have two classes I am currently teaching. I find my two classes are like night and day... the younger class constantly test me, while my other, more advanced class goes with the flow of class, and do not challenge me. I do not come into the class room demanding respoect, I do not throw my "authority" around, and I treat everyone fairly. I discuss with them why they lost points, and am open for a discussion about a varying answer. About half of the class constantly whine about the homework assignments, quizes and lab work, while the other half does really well, and completes the work. I have asked other instructors if I am being too demanding, and they all feel that I am just being tested. That the curriculum is within what is fair to expect of the class. How can I unite the class?
