It occurred to me the other day that I'm not as equipped as I'd like to be to coach Thermo C (ignore the box for now). For Optics C, I followed closely the text we use for AP 1 and 2, Serway. I've got math geniuses, but the results just aren't there like they are with my life and earth science events, where my general strategy is to get an advanced text, teach myself, filter, and trickle-down what I know. The advanced texts in these fields use mathematics that would challenge all of us and detract from the activity because SO is all algebra-based...is it really that I need to make them drill more problems from the book I have, or are there better books (or approaches altogether) out there? I was recommended Knight, but I'm not dropping for it without good reason. Thoughts?
More direct response:
All scioly events have advanced books that are impossible for high schoolers. Physics is especially grueling because many physicists don't understand how teaching/conceptualizing work, so we end up with pages of math to slog through without much understanding. The "perfect" book exists, but I don't know it. I also think there are good online sources. On the other hand, I'm used to studying physics, and I study for scioly differently (mind you I never did any physics events in scioly). Normally I collected as many references as I could find (websites, lecture notes, textbooks from the library/in our school), and I effectively made my own "textbook". This starts from an index of topics (say from the rules + from textbooks/lecture notes), and I added lots of info as I went. Most physics classes/students seem to think that the focus should be on the problems and repetition, which to be honest is pretty true of classical mechanics.
Is the issue "all of Thermo" or specific topics? Are none of the problem solving methods sticking? This might be fairly general, but I've found physics is best done by trying to learn a concept, doing some examples, reviewing (eg. How to solve these problems + remembering what the point is for recognition), repeat if something wasn't understood. The issue I found when teaching is most people expect physics to be math with instant answers, but it requires going back, figuring out what you didn't understand, rechecking, etc. Of course, that process is difficult to get right.
On Me:
So as I said, I'm biased from studying physics and dealing with thermo / stat mech in ~3 instances (including calc-based). I'm also an astronomer, and thermodynamics is the physics about the most related to the astronomy of stars I love! In class, I ironically found Thermo to be the "most approachable" compared to other physics, see...
For some context/excitement, the Laws of Thermodynamics essentially were made with the specific purpose of understanding steam engines and fundamentals shouldn't force you to slog through pages of coordinate system math like in classical mechanics or impossible to understand E&M equations. It starts from observations and fundamental/philosophical questions, like "What is hot vs. cold?" and "How do I 'use' energy?", which allow for awesome qualitative/conceptual discussions about defining hot, cold, energy, etc. If anything, if I supervised, I'm worried about running the build.
I admit textbooks are sparse, but I didn't know if it was really any better than dealing with Optics, etc. I know for lower/intermed levels in college we used Univ Physics w/ Modern Physics, 13 ed by Young & Freedman. Their thermo is nice b/c it reviews everything, even ideal gas law, with almost no calc save for some of heat capacity/entropy (which is of course unfortunate considering how important those topics are, but I guess it's meant for college). I also have heard Knight/Giancoli are the main books for general physics reviews that are more approachable with mostly words/alg-only, but I would wager that those types of books might be more cursory. On the other hand, for ~9th graders, good intros are perfect. Giancoli I think usually you can find more often at least? I agree don't buy anything without proper inspection/asking around.
