There's also classes about calculus proofs. I also took a calculus focused statistics class, and a three term physics series focused on using calculus. And then there's pre-calc which isn't really a calculus class but it's still related to calculus.

Late comment reply, but Analysis is really hard to grasp. For me, it wasn't until the end of the course when everything started to "make logical sense" so that the questions were actually simple by the end, but dauntingly impossible at the start.

[@bryantg8749]

@@zwerg8474 SImilarly, I think that throughout math you get an appreciation for calculus, algebra, geometry, with how fundamentally it is very complex, but we learn the "easy problems" during early math without regards in how their derivations came from. During my other half in my second major for biochemistry we had taken physical chemistry which is just theoretical math and physics on a logical level (thank you pure math other degree) where we spent a week and a half to derive the most basic chemical equation of PV=nRT through partial differential eqs. But for most chemistry students, it is just a plug and chug "assuming" many constants and things xD. I guess this is why we say from a top down perspective we have: math-> physics-> chemistry-> biology-> etc.

[@vaughanwilliamson173]

When I saw this video become available, I thought there might have been a discussion on techniques bprp uses to bring all, or as much of the class, into an enthusiasm and understanding of the subject material. I would prefer if I can see as much of the class as possible gain understanding and grasp principles rather than reward the top achievers who would likely be the top achievers without the "bribe" anyway. If I could indulge my initial understanding for a moment, I believe one of the best "real" motivators is for students to see the theory presented and its correlation in practice. It also helps when a student feels that the teacher is "there for them". In other words, a teacher needs to show empathy and understanding of the learning processes and be ready to step down or backwards to help reinforce points that might have not been thoroughly understood in foundation studies. Obviously, we need students with the the motivation to learn, but wouldn't it be great for a student to be able to hold their head high with a comfortable grade even if they actually scored the lowest mark in the class! Wouldn't it be something if the class could aspire to beyond the marks necessary for a "bare pass"!

[@hardyfanrox2001]

its not about the reward. by setting the rewards as gift cards for 100, the presented goal is for the kids to get 100. In actuality, the real goal is that the kids improve, and they probably will when they are all held to a high standard. I'm sure bprp rewards all students for progress in the lessons that you don't see online, which is the overwhelming majority of his teaching

[@drandrewsanchez]

I commend you for giving points to students who do everything right and only miss small errors. During my engineering studies, my calculus and other freshman courses were rather strict with points and rarely gave partial credit. Although this conditions students to decrease important errors, I believe this discourages the majority of students from understanding the main concepts.
