The students who make teachers afraid just by their very existence. ................................. AND ANTI SOCIAL BEHAVIOR!!!
Prejudices like not being told GFY, threatened, faced with constant insolence et al. Frankly I don't know how some teachers do it. I admit I grew up in an authoritarian atmosphere both at home and in school and frankly I believe it worked well. Today the pendulum has swung so far in the opposite direction to make teaching more like being a caretaker in a zoo than a provider of knowledge and facilitator to learning.
