As far as my experience About the lessons, or teaching style, and my instructors in Kaplan, I think students are the most important part in the teaching process,and a good instructor is a plus. Kaplan books are very nicely written and anyone even without the teacher can do it, However, good instructor is a pluse as I mentioned, I have had great teachers.
Anyone with a little backround in Sciences and math, and some test tricks will be a good instructor, this is what I think.
