Kids today will score higher on an IQ test from the 30s than kids in the 30s did. And these tests are educationally loaded. This climb has been consistent since the tests were first introduced.
The Educational Testing Service revised the method of scoring several years ago, making it appear that students are scoring better. (They juggle the numbers; they do not teach academics.)This deception makes both students and parents think the students are learning more, but they're not.
Have you ever watched a cashier stand, lost and confused, when the computer/cash register wasn't working and he/she didn't know how to give you change? I have.
Have you given a cashier $2.01 for a $1.76 item and watched as he/she stared in horror at the money in hand, not knowing what to do with it? I have.
Have you ever tried to read some of what passes as educated English sentences ("creative spelling", you know)? I have.
I repeat: read None Dare Call It Treason and learn a lot about our modern educational system.
