kids learn fractions with rhythm. on power of 2

Tapping out a beat may help children learn difficult fraction concepts, according to new findings due to be published in the journal Educational Studies in Mathematics. An innovative curriculum uses rhythm to teach fractions at a California school where students in a music-based program scored significantly higher on math tests than their peers who received regular instruction.

"Academic Music" is a hands-on curriculum that uses music notation, clapping, drumming and chanting to introduce third-grade students to fractions.

Students in the music-based program scored 50 percent higher on a fraction test, taken at the end of the study, compared to students in the regular math class.
Significant gains were made by students who struggle with academics. The researchers compared the test scores of lower-performing students in both groups and found that those who were taught the experimental music curriculum scored 40 percent higher on the final fractions test compared to their lower performing peers in the regular math class.


D - wow, those are amazing results!

I've mentioned in the past about how various computer-related concepts require a firm grasp of "2 to the power of XYZ" concepts.
Computer memory of 1Kb (kilobyte) is not 1000, it's 1,024.

D - I've also toyed with using musical timing notation to indicate how colloquial speech is deformed from pronunciation implied by formal spelling. The idea is that a human being (all of us) have roughly the same lung capacity. This is related to the amount of air exhaled during speech. Ultimately the need to take breathes periodically could become an issue.
Due to these consideration, I think the longer a passage, the more the sounds get truncated, deformed, or even completely removed.
I need to map it onto musical notation to see how it holds up.
For example, in one of Peters's studies, students were asked to rate undergraduates who received what looked like different test scores. Numerate people were more likely to see a person who got 74% correct and a person who got 26% incorrect as equivalent, while people who were less numerate thought people were doing better if their score was given in terms of a percent correct.

D - numeracy is a gift that keeps on giving. Numeracy makes a consumer resistant to misleading claims.

Couples who score well on a simple test of numeracy ability accumulate more wealth by middle age than couples who score poorly on such a test, according to a new study of married couples in the United States.

One of the results of the studies is the first quick test for establishing an individual's risk intelligence.
The "Berlin Numeracy Test" has been available at the website in German, English, Spanish and Dutch since early April 2012.
The test works twice as well as previous methods and only takes three minutes. Traditional tests, which tend to determine general cognitive capacities, like intelligence or attention control, provide little information about a person's risk competency.
