Some people may think that tutoring and teaching are more or less the same, but the truth is that there are several key differences between the two.
Teachers develop lesson plans that they must teach at a certain pace while accommodating various learning styles. Many times I've heard students say, “my teacher goes too fast” or “I don’t understand the way my teacher explains it”. The truth is, unless the entire class is very confused, there is probably nothing wrong with what the teacher is doing.
The teacher attempts to get the majority of students to understand, but sometimes there are a few that don't. And that’s where tutors come in. Tutors can adjust their style and methods to fit the learning style and pace of a particular student. It is not the tutor's job to teach a student new material, but rather to explain those concepts a student might not have understood when it was thought to them.
Overall, I think teaching and tutoring complement each other, but they are not the same, and one does not take the place of the other.
