Math Anxiety Affects Skills As Basic As Counting

thirty-seven writes "According to four Canadian psychologists, a study they have conducted shows that math anxiety, 'the feeling of fear and dread of performing mathematical calculations,' can negatively affect mathematical tasks much simpler and more basic than previously thought. In the study, participants were asked to count black squares on a white screen. The number of squares shown ranged from one to nine and participants were given as much time as they wanted before answering. When the number of squares was in the subitizing range (one to four), both math-anxious and non-math-anxious participants performed equally well, but when the number of squares was in the counting range (five to nine), the math-anxious group took longer and were less accurate. The University of Waterloo's news release about the study includes this interesting note: 'Previous studies have shown that a weakness in basic math abilities has a greater negative effect on employment opportunities than reading difficulties [do].'"

      I took part in a psych study about a decade ago (conveniently at the U of Waterloo) for a similar thing. I was asked to count arcs -- line-drawn half-circles, pointed in an upwards or downwards direction placed randomly on a screen. There would be somewhere between 5 to 15 of these on the screen, and instructions were to count all the "upward arcs" or "downward arcs" as fast as possible. After a few trials, I thought myself so good at this counting that after just a flash of the screen I would hit spacebar indicating I had counted them, then count them in my head and answer. I'm pretty sure I got almost all of them right. Half way through the experiment, I got really bad at this for some reason and even had to count one arc at a time or take a wild guess if I had hit spacebar too early.

      Repeat the experiment; but have all participants(normal and anxiety groups) take a pill ~30 minutes before the questioning. Half of each group will get a placebo, half will get a milligram or two of Lorazepam.

As well, an instructor is usually not guaranteed that all his/her students are computer science majors, so tailoring examples to the audience is not always practical. There isn't time in class to come up with one analogy for the biology majors, and another analogy for the chemistry majors, and then make it really abstract for the math majors, etc. Again, it is the student's responsibility to grapple with the concepts and notation on their own, and if they still can't figure it out, then ask for help!

Thus we can have a simple three word sentence, , or we can make it a long complex sentence but it still fits that same basic pattern.

Then you can develop some simple easy tests or questions to determine that the student has learned step N.

At a younger age (elementary school) I simply found math to be non-practical, and therefore ignored it(which is to say I did the bare minimum to get by in class). Once I did this however, by the time I got to highschool, I had severely fallen behind in math all around. My first and only class I failed was algebra, which I retook and finally passed with a C. To me, it was such an abstract thing that it seemed pointless in its difficulty. I should qualify that in all other subjects I excelled, including things like networking (boolean functions and binary, that I saw had practical benifit, I could do in my head no problem) Now, after serving in the military, and going back to college, it has been over 7 years since I had a college level math course, and still struggle, but I have found something that helps me tremendously.

But as I prepare to go back to grad school for a PhD, and therefore need the GRE again, I'm struck--yet again--how absolute shit I am at arithmetic. Questions that require me to just manipulate variables around are no problem, but if they throw an actual value in there, and I have to work on that with scratch paper, I have to be REEEEALLY slow and careful, because I make more stupid arithmetic errors than anyone I know.

    I also joke (but not joking, really) that I can't count. I'll count something 3 times and come up with a different number. I'm terrible. Terrible.

    Writing code in R is easier for me than the multiplication table.

    However, as an applied linguist, I also know quite a bit about another cognitive activity, and I think I've noticed a pattern. When I'm learning a new language, I tear through the grammar and make very few mistakes. But vocabulary? It's here and then it's gone. I study the same words over and over and over again, and they just don't stick. It's embarrassing.

    So what do these two things have in common? Working in code, moving variables around, and human language grammar are all procedural knowledge. They are "processing"-intensive. Numbers, the multiplication table, and vocabulary are all stored, static knowledge. They are memory-intensive. So if I'm bad at those things, perhaps we would expect that I would also have a terrible memory, right.

    Guess what? I live by lists and notes to myself. I have a memory like a sieve. I first started doing this with my research--taking detailed notes on everything I did--because I once realized when I was done prepping, carrying out, and interpreting a particularly labor-intensive analysis of some of my data, that I had just done it the previous weekend, and just... forgot. Luckily, my findings were the same both times. Sometimes I find things that I've written to myself and I have no recollection of writing them, but I know my handwriting, so I just do what they say. Seriously. I'm like the guy from Memento.

    So at the heart of this whole "math anxiety" thing, I think, we might just have different cognitive styles at work here. I'm a university researcher. I'm not dumb. I've turned out fine, by doing the things I'm bad at in a way that takes advantage of things I'm good at. You know, like everyone does all the time. What might make people anxious about math is that--and this is coming from a professional tester (what do you think "item response theory" is for?)--we assess it in a very one-dimensional way that does not "bias for best" (a saying in the testing community--design tests that allow the examinee to show off their best, because that's what we're really interested in).

    In the US, at least, we have a really flawed way of teaching and assessing math skills--one which, I think, leads a lot of people to quit because they think they can't do it, or that it's boring. Math is no more boring than stirring a bowl, and everyone loves cake. It's just a means to an end, but we never get the actual cake in the school system, so people get all worried about stirring and finally just end up buying cake from the store and saying "wow, you must be really good at stirring"--when the pros use machines for that crap.

    So, to sum up, I don't actually think we have an "anxiety" problem. People are anxious because they think they suck at math. They think they suck at math because they suck at math. But sucking at math might be due to totally benign cognitive style differences that are easily routed around. --If we can fix our pedagogical and assessment approaches to math education, I think you'll see this "anxiety" disappear, and find that most people can handle math-intensive tasks if they are presented them in a better, and more realistic, way.
