I think the education process is the most important part. Over the years is seems the teachers have lost the interest in caring about how their students are doing. Or they just assign work and leave them be unless a student asks for help. In case of my education, most of it was self taught. Teachers proved to be unhelpful, and merely just dispensed work and tests. Majority of the students didn't do very well because they had parents sometimes working two or more jobs and they just could not teach themselves.
So as a person to teacher, make sure you aren't leaving your students behind. And don't just bury them with work either. The most important part of the education process is to keep the student engaged. Boring them with repetitive tasks and useless facts only makes it harder for them to learn. If they aren't doing well, be supportive and try to determine why this is so. Sometimes giving a damn does do wonders in the classroom.
