Learning A Lot of Vocabulary: A New Idea About How It Happens

Posted by Lantian August 3, 2007 in the Group General Discussion .



Does Cpod encourage and support this idea of parallel learning? Is it the key to learning A LOT of vocabulary without traditional memorization? Have the learning ideas in the article below been discussed in second-language acquisition academics?

Here are some key points in the article below.  

1. People learn 60,000 words without flashcards

2. Parallel exposure and a gestation period

3. Talking and reading are key

4. One needs harder words to settle the easier ones. 

Over time and on numerous occasions I have read in the Cpod posts of learners having frustration going from one level to the next. More often than not John P has asked learners to be patient and that going from one level to the next takes time, especially from say elementary to intermediate. 

When I read the article below, it sounded like the process that these learners were going thru was almost exactly the same as that described about young babies on their road to speech. For a long while, babies will just say 'ma ma and papa, give me" and then it seems like all of a sudden they explode into full sentences and a cacophony of new words.

What is interesting in the article is that researchers are now understanding better that the kids are working on vocabulary, somewhat in the background, for lengthy periods of time. It is only when they have a good level of comfort with a certain range of words, that those words spew out in an apparent torrent of language. Importantly the kids continue working on the next batch of words, it's a kind of learning in parallel.


Learning language formula

Exposure to a set of vocabulary over a constant protracted period of time (speaking and reading)


Time for the mind to figure out the words


Exposure to a new set of vocabulary over a constant protracted period of time




Doesn't this sound to you like the Cpod levels? Everyone keep listening and working those exercises!! 

What I do think is not emphasized enough is that learners have to keep finding new ways and variations of the set of vocabulary for a long enough period of time to figure out meaning. The production then follows. To keep going though, there must also be exposure with the next 'higher' set of words. Till 60,000 becomes second nature.


Here's the article, your thoughts? New idea or same ol' same 'ol with a new ad campaign?

How baby babbles become talking tsunami

By LAURAN NEERGAARD, AP Medical Writer Thu Aug 2, 2:08 PM ET

WASHINGTON - It's called the "word spurt," that magical time when a toddler's vocabulary explodes, seemingly overnight.

New research offers a decidedly un-magical explanation: Babies start really jabbering after they've mastered enough easy words to tackle more of the harder ones. It's essentially a snowball effect.

That explanation, published in Friday's edition of the journal Science, is far simpler than scientists' assumptions that some special brain mechanisms must click to trigger the word boom.

Instead, University of Iowa psychology professor Bob McMurray contends that what astonishes parents is actually the fairly guaranteed outcome of a lot of under-the-radar work by tots as they start their journey to learn 60,000 words by adulthood.

If McMurray is right, it could have implications for parents bombarded with technology gimmicks that claim to boost language.

He thinks simply talking and reading to a child a lot is the key.

"Children are soaking up everything," he said. "You might use 'serendipity' to a child. It will take that child maybe hundreds of exposures, or thousands, to learn what 'serendipity' means. So why not start early?"

Sometime before the first birthday comes that first word, perhaps "mama." A month or so later comes "da-da." Now, it may seem like it took the baby almost a year to learn the first word and a month to learn the second. Not so. He'd been working on both the whole time, something scientists call parallel learning.

Up to age 14 months, on average — and how soon kids speak is hugely variable — words pop out here and there. Then comes an acceleration, and after they can say 50 or so words there's often a language explosion, sometime around 18 months, McMurray says.

What sparks the spurt? There are numerous theories centering around the idea that a toddler brain must first develop specialized learning tools, such as the ability to recognize that objects have names.

The new research doesn't negate those theories, but it suggests "we might be missing the big picture," says McMurray, who developed a computer model to simulate the speed at which 10,000 words could be learned.

He found that as long as toddlers are working to decipher many words at once — that parallel learning — and they're being exposed to more difficult words than easy ones, the word spurt is guaranteed.

Consider: Scientists know children learn through the process of elimination. If Mom asks, "Please pass me the plate," and the child sees a fork, a spoon and some round thing, by age 2 most will match the new word to the unknown object.

That fits with McMurray's model. As you acquire many words, the process of elimination for new ones becomes easier so that vocabulary accelerates.

Then he compared easy words parents use with babies to more sophisticated adult speech. There was faster early learning with exposure to simple words, but then new vocabulary slowed — only to speed up again with exposure to harder words.

"The work is extremely creative," said Dr. Janet Werker, a language development specialist at the University of British Columbia.

Her own research shows that some words are particularly difficult for toddlers, including rhyming words such as "bin" and "din." The new work shows that trouble won't stall overall learning.

"It suggests the fact that some words are more difficult to learn than others is part of what propels the vocabulary explosion," Werker said. "That's really insightful."
