Student: But instead of writing a program to reduce the fraction could we just do it by hand?(She came around after I showed her some of the fractions we needed to reduce for the spirograph project.)

@futurebird actual motivating use cases are so crucial! Thank you for sharing this & applying this praxis in your classroom

@PetraOleum I don't really get it. All I wanted at that age was a program to do all that stuff.

@ryanprior I sometimes forget that I have a very low threshold for busy work. And a high level of excitement for finding a way to avoid it even if it MORE work.

@futurebird @PetraOleum my dream from the time I was a 7-year-old was to sit in a cozy alcove and eat fruit gummies while a computer did my math homework

@ryanprior @PetraOleum I had a math teacher who let us use graphing calculators but was had to erase programs before the test (fair) I asked "but I can write a program during the test?" "why not?"That was when I started like math TBH.

@ryanprior @PetraOleum We were doing Riemann sums! Which I think are almost a little cruel if you don't write a program. But, few students have the foundations in programming to do this efficiently. So, instead most teachers only give dead simple problems with easy calculations which are.. I think boring. As if it wasn't boring enough already. The interesting thing is seeing how changing the parameters improves the result.

@futurebird @PetraOleum I didn't start learning math through programming until I was probably 16, and then I intensified it significantly during college. I know at least one teacher at my high school was doing things in that area, teaching remedial algebra using the Racket language. I wasn't in a remedial class though.

@futurebird Seeing those examples where doing it by hand would be too much seems like a good way to show how programming can be useful though!

@futurebird @ryanprior @PetraOleum I had a teacher that let me use programs if i wrote them myself and showed her how they work. She said my solution to find the intersection of two linear functions was a proof for matrices, but i still don't know what that means

@RnDanger @ryanprior @PetraOleum If she laid systems with more variables on you ... you would have figured it out.

@futurebird @ryanprior @PetraOleum I might think about that with a whiteboard later

@futurebird @PetraOleum One of the best pieces of advice I’ve ever received was from a maths teacher when I was 9 (she sadly died a year later). She said:Good mathematicians are lazy. Don’t solve the same problem twice and don’t introduce unnecessary steps.I found it frustrating for the next nine years of school that we weren’t allowed to follow that advice in our coursework or exams.If a process is rote and mechanical, don’t waste time practicing it, teach a machine to do it. I started programming a couple of years earlier, but I don’t think I’d have appreciated the value of it without her.

@futurebird @PetraOleum I have the privilege of teaching some seriously smart mathematicians to program.Once, the problem was "multiply the largest 2 of the 3 inputted numbers". Most people used a couple of if. One multiplied all 3, then divided by the smallest! Sure, there are numerical analysis issues, but I love the insight. _That's_ what takes the art forward.

@futurebird @ryanprior I sometimes joke with my children that mathematicians work very hard to find the lazy ways to do things.
