This was a pretty unsual on-line contact for me — it came from a grown-up, someone who signed his name.
It came from a high school math teacher. I won't print his name here, his school division may not think it's too cool to use the divisional email to conduct this kind of business, but if he wants to hit the comments section and identify himself, feel free.
I didn’t think that my occasionally mentioning soccer incidents in which teenagers can’t do the math in their heads to figure out how much time is left when you’ve played 32 minutes of a 40-minute half in soccer constituted berating and bias, but here’s what the teacher had to say.
Besides, the anonymous trolls really enjoy it when someone slaps me down.
And good on him for having the gumption to sign his name:
"I’ve been watching you berate the younger generation on your blog for some time when it comes to automaticity of math facts. But, a recent study has shown that younger Canadians (16-24 yr olds) score higher in numeracy than adults as a whole. It’s a marginal difference but it does speak volumes about the bias you’ve displayed on numerous occasions. (see pages 80 and 82)
I am 33 years old and teach math. I have encountered far more people older than me who can’t recall basic math facts than people younger than me who cannot do so. I have always read your blog with glee as you describe times that you’ve confused people by asking them to do some minor calculation in their head — I do that all the time. Except it’s my parents, grandparents, uncles, aunts, etc who can’t keep up. But, I try not to generalise on my anecdotal experiences."
