My Data Communication & Computer Networks (DCCN) teacher was the best teacher I've seen.

Teaching can be super hard. You're one against like sixty others who aren't interested in being there. To make that good learning environment, making the subject interesting etc, it not easy. Some justify that, "I can only bring the horse to the water" & proceed to just regurgitate whatever is on the book. Others cross question you & impose punishments - try to make you learn by fear.

But my DCCN teacher - she had the right balance between strictness & humour. So kids took her seriously (did homework, weren't late), yet never feared her - we felt comfortable asking doubts/questions.

She had some good tactics, like asking us to teach certian chapters - that made us learn better. She would revise them in the end also, incase we missed anything.

My best moment with her was when I scored the highest in my internals. She picked up my paper & showed the class - "see? Just two pages & he scored so much". There's was always those students who pump out a lot of stories/essays or whatever that comes to their mind about the topic in question. Lots of teachers just blindly give marks - "oh, s/he wrote this much, so it must be right".

But my DCCN teacher had zero tolerance for garbage. If you're wrong, you're wrong. Some even believe that the number of marks = number of lines you have to write!! Doesn't matter what you write. So, I was super glad when this teacher upped the standards.
