"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?

reasonably close is more than enough. ask the crew of the challenger.

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.

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."

Sample problem, If you could earn $65,422 a year in a job that requries "normal" math skills and you can make $24,175 in a job that only requires "reform" math skills, estimate how long you will be on food stamps.

Hell, we have a perfect example of the degeneration of common math skiils right here on BP...here's my response to some who had asked how many gigabytes BP uses after he was already told the data rate:

Not trying to come off like a jerk, but this just got to me. Uh, how about trying some basic math?

60 seconds x 60 minutes x 24 hours = 86,400 seconds in a day.

30 days (avg. month) x 86,400 = 2,592,000 seconds in a day.

Avg bit rate of 2mbps (2 million bits per second) = 250,000 bytes per second.

2,592,000 seconds x 250,000 bytes per second = 648,000,000,000 bytes (648 gigabytes) per month.

Took me all of about 30 seconds to figure this out (about four times longer to type it).

To which our local cyber-hero flew in for the rescuse to claim that this was a "lenghty calculation", and the poster to whom I was responding claimed he was "pretty sure that a large majority of people couldn't do that."


I wonder if the IRS would've accepted a check for a "reasonable amount" of the taxes I owed... :roll1:

it should be 2,592,000 seconds in a month:tongue2:

a) My point was that joe schmo doesn't know how to plug "mbps" into an equation, which I clarified further in a second post.

b) You're still on the cyberhero kick? :slappy: But I'm sure that your tired schtick doesn't involve any cyberhero posturing, since your roads only go one way.

I'm still waiting for an explanation for this bizarre obsession of yours with cyberheroes. Maybe the third time is the charm.

What am I spinning? You came out of left field with the cyberhero nonsense, somehow stemming from me calling you out on the search function. So I asked if you also sought a cyberhero status by calling out newbies on the search function.

You're free to explain this cyber-popularity contest at any time. Does someone gain in status by mocking flamers? doctorbs?
