This video is completely worthless for the people they claim to be targeting, the average student. It literally doesn't talk about where math is used in the real world in any meaningful terms to a highschooler.
- tibbon 15y agoRight, a student is thinking, "WTF is this quadratic formula for?" might not have gotten much from this. This shows the benefits of the end-game, not the middle point. Bridging that gap for students I think is the hard part.
- daeken 15y agoI learned the quadratic formula in algebra II (the highest math class I've taken) and promptly forgot it. Then a year or so later, I was writing a raytracer and realized that the ray-sphere intersection is just the quadratic formula. I couldn't help but wonder why we weren't given a single use case for it in school.
- tibbon 15y agoThe only reason I can imagine is that most use cases require other specific knowledge that will also seem like useless stuff to 99% of the students and its hard to find a use case that fits most of their probably interests. "So in the future, when you're writing a ray tracer..." just doesn't ring with most students anymore than the word problems that required the formula either.
