have to agree with you to some extent, though I don't feel good about it.  yes, teachers must play a significant role in the learning process.  the key to a good teacher is to motivate the students to learn; that is why they have school, a place to learn.  the teachers' responsibility is not only to assign work and correct papers, they need to make learning exciting and purposeful; to engage the students.  if the parents are largely responsible for their children learning then there would be no need for schools.
