I received this in my inbox the other day and I must say, sad but true.

Last week I purchased a burger for $1.58. The counter girl took my $2 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies, while looking at the screen on her register.

I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help.

While he tried to explain the transaction to her, she stood there and cried.

Why do I tell you this?

People *way* overestimate the success of past education, mostly because of increased expectations. “Literate” today is a much higher standard than it was 50 years ago. The same is true of math.

In part there has been a change, where the best educated of today are going much further much more quickly than 50 years ago. 80 years ago geometry was a freshman college level course, now it’s a sophmore highschool level course. In the process, we may have left some people behind, and created an education system that favors (optimistically!) the priviledged while letting the underpriviledged fail to a greater degree. But honestly, that girl wouldn’t have been put in front of a cash register 50 years ago, and she probably wouldn’t have been any better at math.

On the flip side… I’m guessing that 80 years ago the basic long division and/or multiplication was practiced and known by a far greater percentage of those who were lucky enough to get into that geometry course. I’m not so confident that the same percentage today would be able to handle some of the basics without their TI86 in their hand.

No doubt I agree we have some amazing advancements going on these days, but it’s all relative.
