If I was taught programming in high school the same way I was taught math, I would've hated it, deeply.

Most of math was about number crunching and the application of arbitrary formulas to arbitrary equations.

I can imagine, 20 years from now, a high school student will have to solve the following question:

"Write a recursive function in C that finds the minimum number in an array of integers".

Then imagine the teacher himself/herself has absolutely no interest in programming what so ever, and is only teaching it because the board of education decided that children must learn it.

That's actually a reasonable question. What's a lot more likely:

"Here are fifteen for loop headers. For each one, write how many times the loop body will execute."

xyzzyz2• 15 years ago

This is undecidable.

hasenj6• 15 years ago

It's reasonable for us. Most people (who are not into programming) would find it ridiculous and pointless.

The above exactly the kind of exercise we were assigned in my high school's intro CS course. The course was taught by a math teacher.

BUT:

The school waited until a month before the semester started to tell the math teacher that she'd be teaching the course. Worse, they had already picked out a textbook that was filled with exercises like this. Worst of all, she had basically never done any programming before.

As time went on, and she actually had a chance to learn the material, this kind of coursework was replaced with more interesting and useful programming assignments.

I later took a calculus course from this teacher, and in that course, she actually took great pains to avoid repetitive problem sets; almost every problem she assigned was designed to teach us something different.

Repetitve exercises are likely easiest to assign and grade.

I feel like math teachers have a fundamentally different task than coding teachers. Everyone needs at least a low level of proficiency in math - being able to make change correctly and balance your checkbook. Not everyone needs a low level of coding proficiency.

If you've reached the level in your education where you need to learn to code, then you've probably already advanced past the point where everything has to be presented as "fun" before you'll learn it.

Hey, there was a time when most people could get by just fine without even knowing how to read and write.

With the proliferation of computers into every aspect of life, it's not unimaginable for programming to be considered essential knowledge that should be taught in schools.

wgrover3• 15 years ago

I'd agree with you if it weren't for the iPad. Computers have proliferated, but they're also evolving in a way that makes programming knowledge less important (at least for the majority of people).

dwc3• 15 years ago

I'm sure that's how basic math proficiency was viewed in the past. These days almost everyone would benefit from some rudimentary knowledge of programming, but it's not yet viewed as essential. Every day I see people doing repetitive manual tasks on the computer that could be automated with just a tiny amount of basic shell scripting. How long before this is taught to all kids in primary school, and facing many of the same problems as math today?

wgrover3• 15 years ago

I agree - there's no question that lots of people would benefit from even a little coding knowledge! But computers are evolving in a direction that makes coding knowledge less useful - shell scripting is irrelevant in a world full of iPads. In that future, the only people who need any coding knowledge would be the folks who write the software for the iPads and such, but the idea of teaching everyone BASIC in middle school just to introduce them to programming (like I was) would be pretty quaint.

I don't like that future, and I don't know how we'd get kids interested in programming in that future. But returning to the topic, I don't foresee a near future where something similar happens to basic math knowledge.

> if you have to tell somebody that something is fun, it means that you have lost the argument.

Couldn't agree more.

I have very fond memories from when I was 9 or 10 about a book called I Hate Mathematics: http://www.amazon.com/Brown-Paper-School-book-Mathematics/dp...

It was the thing that really made math fun for me. So sure, stop telling kids that "math is fun", but don't stop trying to make it interesting; it's definitely possible.

>But I’m convinced that almost anyone can be drawn into maths if they are presented with something intriguing or surprising which prompts them to want to investigate

That's what I used to think when trying to get other students into programming -- like getting a kid do say 'Holy crap, I just created multiplication'. But it doesn't seem to work that way.

I've come to be used to the concept that other people think on a completely different plane than me, so it's pretty hard or often just doesn't work at all to try to find this 'intriguing or surprising' thing that can get them others to be interested.

dwc3• 15 years ago

I agree with you. But I have to add that there's a big difference between math anxiety and disinterest in pursuing a graduate degree. There's nothing wrong with someone choosing to pursue something else even when shown the intrigue and beauty of math (or programming). But there's everything wrong with the mind-numbing approach to math taken now.

"Making math fun" is fine, but most teachers interpret it as "mixing fun stuff into math, which is inherently painful and boring," because they're focused on the kids who aren't doing well. To them, making math fun is the same idea as bringing a clown into the pediatric burn ward: "Let's make this suck a little less." That attitude rubs off on the kids.

What those teachers don't get is that math is most fun when you are using solid, polished skills to explore an area where you're still learning. The teachers are stuck in the standard educational mindset, which is that getting enough practice at anything to develop polished skills is "rote" and horrible. Plus it slows down their curriculum. So they move on and just do some review now and then, and the mediocre students end up with no solid skills they can rely on. All their skills are a little iffy, so they can't do anything with confidence, and everything is stressful.

Agree with the argument but the title (on HN) doesn't sound right.

I suggest, Stop trying to make maths look "fun"

Eeee, when I were a lad, maths weren't fun! You did 14 hours down't mine and only then were you allowed to try yer 'and at partial differential equations. And if yer got one wrong'un, teacher'd beat you with a wooden pole (etc etc) (yorkshire post, scnr)

Hmm. Finding maths so dull was probably one of the main reasons that I didn't peruse a degree and CS or physics. Which was a disastrous decision for me personally. Not that I just couldn't face studying anything unexciting per se, but that I (wrongly) assumed that if I didn't find something interesting then i could never be sufficiently good at it. At high school I was 'streamed' into one of the lower tier math classes, which I resented - result was getting a higher mark in the end than most of the top-tier students. But perhaps I would have been better off in a more advanced class where I'd struggle more but at least find the stuff interesting.

Anyway my point is it's a shame to turn people away from maths by offering such stale curriculum.

My oldest son has dyscalculia and just sucks at crunching numbers. He had a terrible, terrible time with math in public school and really hated and dreaded the subject by the time we pulled the kids out to homeschool. It was clear to me he would not be able to memorize his way through math like his mom had. (I was in my thirties when I discovered some of this stuff had actual uses. sigh) My top priority for math with this child was to teach him "math is your friend". He's a science geek (which is tough when math is not something you are good at) and loves physics. He taught me most of the physics I know (speaking in little words and repeating himself a lot) when he was 14, which stood me in very good stead when taking certain college classes later on.

A few things we did:

Chapter books, full of discussion about math and light on formulas.

Let him choose a statistics track over an algebra/geometry/trig track. (We did some algebra and geometry but not too much.)

Read about halfway through "A tour of the calculus". I dropped out of calculus my first quarter in college and never wanted to see the subject again, after having been inducted into Mu Alpha Theta in 11th grade. He would spend an hour on this with me because it was the only math that made more sense to him than to me and he was happy to watch me get a headache (which I played for all it was worth). This book was chosen because he loves physics and calculus is the math of physics and because calculus really requires you to learn all that algebra/geometry/trig stuff he wanted nothing to do with. I knew I had won the battle when he was whining and complaining one day about not wanting to do math and then got all perked up at the idea of working on reading a couple more pages of this book with me.

We also did "fun" stuff, like card games and such in place of workbooks and that did have some value. But reading part of "A tour of the calculus" was the single biggest thing I did to get him past this mental and emotional block. Which I guess largely agrees with this article, though perhaps framed a little differently.

This "Mathematician's Lament" is (by far) the best critique of the modern mathematics education that I've seen to date:
