Recently I had to remind students of where the line of help lies. I help them learn, I don't train them to score marks. Specifically I got an email begging to be passed for some reason or another (not usual mind you). The student asked to be passed because I had been helpful in the classroom, so I should likewise help by awarding the passing grade. The response went something like this:
Dear student: do not mistake my friendly smile, classroom patience, and simple explanations as "easy marking" - You might be shocked.
Most teachers have to do two things: TEACH and ASSESS. They are not the same thing.
The person who teaches is there to assist learning. They are your friend, and it's their job to assist you get ahead in anyway they can. Your job is to get everything out of that person that you can.
The person who assesses is there to measure if learning has occurred. Their role is certification or assurance. They are not your friend, and it's their job to only allow those strong enough to pass. You job is to demonstrate that you are good enough. (You are of course, aren't you?)
