He was very knowledgeable and explained things in depth. He was also very approachable and helpful when it came to questions. Sadly he's only a substitute now.
He was a long term sub for my Chemistry class, and really helps explain things if there are any questions.
the guy's a jerk, he has a right to his opinion but not to take a position of authority as teacher and impress it upon us
Mr Liptrap rocks! Seriously. This is one of the most principaled teachers at Klein. I had him for Chemistry in '91!
I had this guy in '92, and I still remember stoicheometry. Great teacher, and very memorable. Maybe he isn't Mr. Cool, but at least he sticks to his ideals.
A little goofy, but a great teacher! Also had him in '99.
Had him in '99 -- He was a great teacher - Always there to help you.
Very good teacher. He teaches clearly and is there to help you before school
