Hacker News Stories and Comments
All the comments and stories posted to Hacker News that reference this video.This article is full of funny things. If you want to teach people Computer Science just teach them Computer Science. Why waste people's time with math they will push out of their minds as soon as they're finished with the class? I wish we had a specialization-based curriculum for high school. I wasted a lot of time there that I could have spent learning more.Some funny things in the article:
> Discrete mathematics deals with such problems as...
No it describes solutions to those problems. You could also describe those solutions with other types of math. A computer Scientist wouldn't think of this problem in terms of a formula first. They would likely think of this in terms of a Data Structure and thing about the most efficient way their representation's strengths can be leveraged to obtain a solution.
A "calculus-track" Mathematician may think of this as a shape and attempt to frame this problem as an equation that describes the changes occurring in a subset of the problem. Luckily 3B1B just posted a video demonstrating this: https://www.youtube.com/watch?v=VvCytJvd4H0
> Students need classical math more than ever.
I'd say this is debatable. What's the work/value trade off for teaching someone calculus? I just aced my college's calc program and I've already pushed that crap out of my mind.
I'd say it's much more important to be able to learn how to do these things as needed. Learn how to pick up a book, find the chapters you need to read, read the material, apply it, and test your output.
> But discrete math is fundamental to computing and ubiquitous in the real world
I'd say it's not the only way to express those ideas.
> To understand software, you need a basic understanding of computers; for that you need some basic electronics education. [...] There are many ways to build a von Neumann machine—the world’s standard digital computer since World War II...
Lol. Who wrote that in the press release? I'd consider many micros with in-chip roms as Harvard architecture.
I'm getting ready to laugh at the development and implementation of Common Core 2.
