My wife is helping her niece, transcontinental, with her algebra. It has been a real eye opener. The girl is not stupid but she sure comes across as a bit dim despite having made straight "A's" prior to this year. The term common core math has come up and we are trying to figure what the heck that really means. They have no text books anymore so they can't read about how to problem solve the way they used to. Yes there used to be good text books and bad ones; but no textbooks, really?:confused2:
Maybe they did away with textbooks because kids graduate now with a 4th grade reading capability and can't read anyway to comprehend.
They teach math differently now and my wife is trying to understand the new method to be able to build with this girl on what she is being taught rather than starting over. I did find a reference (on-line so who knows if it is true) that stated that the way they teach algebra now has one big failing. That being that while it allows everyone to grasp the basics it screws up the kids that go on to further math as it is not correct and actually prevents building upon it for real advanced math.
Those that go on have to go back and relearn the basics the correct way. It was stated that the tradeoff was worth it since it would only cause a small percentage of kids to have to go back and relearn as the others would never use it again.
Yes there are examples of kids that do well, but as has been stated the school system is failing the children of today, the adults of tomorrow, at an incredible pace. The OP stated issue with the inability to grasp 10% calculations is merely another example of the simple things that are being lost.
Also just the way they think has been degraded. Here is an example of a recent problem issue.
Solve for X
X[SUP]2[/SUP] = 25
no problem X = 5 and X = -5
Same problem
Solve for X
X[SUP]2[/SUP] - 25 = 0
Can't do it.
Same problem
Solve for X
(X-5) (X+5) = 0
Can't do it.
There is a problem with the way things are being taught or not taught as the case may be.
A common statement that is heard.
Why do I need to learn this. I will just learn it in college.
If you don't know how to do it by college then the college math will leave them in the dust and they will spend their tuition money in remedial math classes before they even start their real 4 year degree classes.
