LOOOOOOOOOOOOOOOOOOOOOOOOL
YOU REALLY ARE A MORON!
A GOOD teacher would get the class of people who don't care and don't want to learn anything motivated to learn the subject at hand. A good teacher would inspire the students.
Fuck, man. Just watch Stand and Deliver (1988). Good example.
Of course you think everything is upon the students to be motivated, to want to learn, to want to do everything and anything to please their superiors. Kids don't come out of the womb sayin', "FUCK YEAH, I WANNA LEARN CALCULUS 'CAUSE THAT SHIT IS AWESOME." They get told that by their good teachers and then they're like, "Alright, maybe this guy is onto something... Shit, this stuff isn't so bad. Calculus actually is kinda cool now that my teacher has made it so amazing."
The student should be motivated to learn so he can get a successful job and make something of himself. Shouldn't that be enough motivation? If you want it, go get it. If you don't want it, wash my dishes.
