I loved Dunny1 He was great. If you didn't like him then you need to get a sense of humor. he was very helpful if you really listened.
I had this teacher in 1984 and still remember him as the teacher I hated the most. I failed of course. Now I teach bio+chem and computers myself in California.
CAN BE VERY MEAN BUT IS COOL AND FUNNY SOMETHIMES VERY DIFFICULT CLASS
Teaches a difficult subject well. Makes it very fun. Funny if you're intelligent enough to understand his jokes.
Very funny guy, though, he is a very challenging teacher. Perhaps when all the students fail the lab reports, something is missing in his teaching style...
I loved having Donovan as a teacher. He was so much fun and made me actually like chemistry. Really helpful in explaining anything you asked about.
He has been extremely helpful in teaching beyond the book. He knows the answers to difficult questions and knows where to find the answers that he doesn't know
Mr. Donovan is a great teacher, he is one of my favorites, Have great retirement Dunny!
