Without mentor, no one get taught well.
A mentor is different from a teacher. A teacher often spoonfeeds... a mentor does not.
Very true, these are different roles. Mentors (AKA tutors) need to be very interactive, asking questions, one-on-one, like a physician diagnosing a patient. Teachers usually have barely enough time to deliver the course content, let alone interact with a large group of students.
I wish more students understood the distinction so that they would come to tutoring sessions better prepared, instead of expecting to sit passively through yet another lecture. Some of them even resent being asked questions, claiming that I'm trying to embarrass them. But time is short, the deficiencies must be exposed, if we are to save the patient.
c'mon, crab ..... laws of surds!
