"Reform Math"
If Mili's blood pressure rises at a rate of...

(CBS) Remember when there was only one right answer to a math problem?
Not anymore.
"What does estimating mean?" a teacher asks a student.
"It's something like, reasonably close," says a student.
"Good I like the word reasonable, 'It's reasonably close,' he said," says the teacher.
And that is good enough here in Abington, Penn., where they're teaching 'reform math.'

Still, reform math supporters say their studies show that their programs help kids score higher.

Interesting. If true, could it possibly be because estimating is "good enough" to help with multiple choice tests, if not to keep your house from leaning over?

wasn't that just a fuel tank testing issue?
anyways reform math in a sense has always been around. i don't APPROVE of reform math but i think it needs to be incorporated along the lines somewhere. in this case, i view it as wrong because they are dealing with elementary math. if you are dealing with irrational answers then you have rounding error through calculation and you end up having accuracy and confidence intervals to determine margin of error......but that is just it.......margin of error. sure we can calculate the margin of error to fit what our desired solution should be within its interval, but we never ACTUALLY KNOW if it ends up being irrational and is rounded through significant digits. so in higher level math, it is understandable in SOME instances(mainly because we don't have a choice), but in the case of 2+2=4.......no way. |

I think this might be on par with finding imaginary solutions.

Do kids get bored by drilling? Yes. Do they get empowered by getting the knowledge they ultimately gain from memorization? Yes, they get empowered,? she says.

I generally despise the use of the word "empowered" in any sentence as the majority of people who use that word have no real idea how to use it.
Or, in the words of Inigo Montoya from 'Princess Bride', "I do not think it means what you think it means." |
