Just to humble brag... I had a REALLY good high school physics teacher. He derived the equations, gave us actual math problems to apply them. So all of 221 and over half of 222 was absolutely just a review for me, aced both classes.
Meanwhile, I had friends in class who had gone to big schools and done AP physics, but had no idea math was involved. They basically learned history of physics, but no application or math. They got killed in there.
Shows how important a teacher can be to a ton of students. Any teachers reading this - push your students! They may not like it now but someday they will realize you were the best.
This story reminds me of one of the most surreal incidents of my life.
My high school chemistry and physics teacher (at Boone, mind you, not one of the better high schools in the state) was a young guy right out of college. I am not going to reveal his name because it is fairly unique and he is still teaching elsewhere in Iowa and this story is kind of... well, rather bizarre.
He was not a popular teacher because (1.) he was inexperienced... he tried hard but was new at the job and only human in that way... and (2.) he tried to teach chemistry and physics in a rigorous, mathematical way, the same way one would encounter in freshman or sophomore science classes at ISU.
One day I was sitting in the "nerd lounge" (what amounted to an old closet converted into a computer lab for the talented and gifted program over the old middle school gym... complete with basketballs pounding against the wall and the floor during the day) when said teacher came around the corner and saw me. He was absolutely furious. His face was red, he was hunched over, and his hands were balled up in fists. He looked like a gorilla looking for somebody to fight (as much as one can at 5'10" and maybe 150 with glasses).
He walks up to me. Leans over in my face. He's scowling and breathing heavy. Growls at me from about six inches away, "PLEASE TELL ME YOU LIKE TO BE INTELLECTUALLY CHALLENGED?!?!??" I'm thoroughly confused and a little scared and all I can offer is a meek "yes" before he turns around and storms off.
Later on I hear through the grapevine the other chemistry section (there were two, mine was in the morning and this one was in the afternoon) staged a "student rebellion" against him just before he walked by the computer lab and saw me. Their complaint was his class was too difficult, and they collectively refused to work on any of the material and accused him of abusive conduct for trying to teach material at a level completely inappropriate for high school students. They were done with him, and he was understandably done with them.
The funny thing was after that incident our relationship improved significantly. I think he found me pretentious until he saw that was a good problem to have in a student. Then I became his favorite after he was our chaperone to the Ames Science Bowl and we finished second with me more-or-less playing solo. Stupid Ames nabbed us in the finals. He even said at one point that he was "proud" to be my teacher in the Paul Rhoads style.
I appreciate the teachers I had in high school who drilled me on such material because (1.) it prepared me for difficult classes or (2.) it made it so I never needed to take them at all while at Iowa State because of AP credits or transfer credits from DMACC. The people in the morning class generally all went off to college and graduated. The rebels in the afternoon section, well, very few did from what I've gathered.
