"I was a TA in a far east university in an Engineering department. Generally I consider my self a tough marker, as I expect students to arrive at answers with right logical reasoning. Having said that, I usually had a partial blind eye for students who has genuine drive towards studies -- post grad research types --, because their future shouldn't be eclipsed by a one bad grade. Also I highly control the grade distribution, such that only 5-10% of the class will get A-grade."
Huh? I'm confused... Isn't the goal of the class to make sure that the student understands the material being taught?!
If everybody has a solid understanding of the material, everybody should get an 'A.' If nobody has a solid understanding of the material, then they should get an 'F'. I don't see what benefit controlling the grade distribution offers, except penalizing or rewarding students unnecessarily.
I'd appreciate any comment with a logical basis... it doesn't even have to agree with me.
