he did a good job teaching the class, but he didn't really help when you needed it. he didn't prepare you enough for test and quizes. he wouldn't answer your questions, you had to find them out yourself. hes class was a good class, but he wasn't a very good teacher.
I always hated science, but Mr. Diederichsen was great! He was one of the best teachers I ever had and I'm in college now.
As a pre-med student now, I realize how much D helped me out. Sure, he may not be the easiest teacher, but you'll be glad you had him later.
Mr D is fine as a person to talk to, however teaching is not a strong point for him. Don't ask questions in class!
Best teacher I ever had. Great at motivation and enthusiasm.
had him for three years. love him. awsomest teacher ever.
if you want to go in to a health related profession, take his physiology class! it will help you out a lot!-
Never had him as teacher, but great science olympiad coach.thx for 1st place D
mr. D is my favorite teacher so far! he knows how to push us to our best - 6 hr.
