Does one motivation factor create a more "successful" student, a more successful person?

I was just curious and would like to see feedback on what other instructors have experienced in their class rooms, or in the work place on which (intrinsic or extrinsic) factor "creates" a more successful experience? Perhaps it's a point of view.

I think it is imperative to continuously evaluate your course and strategies.

I think online courses may be more prone to plagiarism the on-site based courses.

I think it is important to check ALL hyper links posted to make sure they are classroom appropriate.

I think having an easily navigational site is imperative to enhancing the learning environment.

It's very important to have a clearly devised plan for late assignments.

Pretesting is a great way to determine the strengths of each student.

I think having students involved with presentations help keep them interested in the material.

I have always had success with planning field trips to a place of business that corresponds with the course work.
