once gender connotations have been imposed on impressionable young minds, they lead those with a gendered mother tongue to see the inanimate world through lenses tinted with associations and emotional responses that English speakers — stuck in their monochrome desert of “its” — are entirely oblivious to

one conclusion that seems compelling is that while we are trained to ignore directional rotations when we commit information to memory, speakers of geographic languages are trained not to do so

if you saw a Guugu Yimithirr speaker pointing at himself, you would naturally assume he meant to draw attention to himself. In fact, he is pointing at a cardinal direction that happens to be behind his back. While we are always at the center of the world, and it would never occur to us that pointing in the direction of our chest could mean anything other than to draw attention to ourselves, a Guugu Yimithirr speaker points through himself, as if he were thin air and his own existence were irrelevant

our experience of a Chagall painting actually depends to some extent on whether our language has a word for blue

some languages, like Matses in Peru, oblige their speakers, like the finickiest of lawyers, to specify exactly how they came to know about the facts they are reporting. You cannot simply say, as in English, “An animal passed here.” You have to specify, using a different verbal form, whether this was directly experienced (you saw the animal passing), inferred (you saw footprints), conjectured (animals generally pass there that time of day), hearsay or such. If a statement is reported with the incorrect “evidentiality,” it is considered a lie. So if, for instance, you ask a Matses man how many wives he has, unless he can actually see his wives at that very moment, he would have to answer in the past tense and would say something like “There were two last time I checked.” After all, given that the wives are not present, he cannot be absolutely certain that one of them hasn’t died or run off with another man since he last saw them, even if this was only five minutes ago. So he cannot report it as a certain fact in the present tense. Does the need to think constantly about epistemology in such a careful and sophisticated manner inform the speakers’ outlook on life or their sense of truth and causation?

The habits of mind that our culture has instilled in us from infancy shape our orientation to the world and our emotional responses to the objects we encounter, and their consequences probably go far beyond what has been experimentally demonstrated so far; they may also have a marked impact on our beliefs, values and ideologies. We may not know as yet how to measure these consequences directly or how to assess their contribution to cultural or political misunderstandings. But as a first step toward understanding one another, we can do better than pretending we all think the same.

there is no good way to quantify those achievements — putting them in a tough spot with voters deciding whether to bankroll this approach again

“We’ve jumped on bandwagons for different eras without knowing fully what we’re doing. This might just be the new bandwagon,” he said. “I hope not.”

$46.3 million for laptops, classroom projectors, networking gear and other technology for teachers and administrators.

If we know something works

it is hard to separate the effect of the laptops from the effect of the teacher training

“Test scores are the same, but look at all the other things students are doing: learning to use the Internet to research, learning to organize their work, learning to use professional writing tools, learning to collaborate with others.”

Good teachers, he said, can make good use of computers, while bad teachers won’t, and they and their students could wind up becoming distracted by the technology.

“It’s not the stuff that counts — it’s what you do with it that matters.”

“There is a connection between the physical hand on the paper and the words on the page,” she said. “It’s intimate.”

“They’re inundated with 24/7 media, so they expect it,”

The 30 students in the classroom held wireless clickers into which they punched their answers. Seconds later, a pie chart appeared on the screen: 23 percent answered “True,” 70 percent “False,” and 6 percent didn’t know.

But she loves the fact that her two children, a fourth-grader and first-grader, are learning technology, including PowerPoint

The high-level analyses that sum up these various studies, not surprisingly, give researchers pause about whether big investments in technology make sense.

Mr. Share bases his buying decisions on two main factors: what his teachers tell him they need, and his experience. For instance, he said he resisted getting the interactive whiteboards sold as Smart Boards until, one day in 2008, he saw a teacher trying to mimic the product with a jury-rigged projector setup. “It was an ‘Aha!’ moment,” he said, leading him to buy Smart Boards, made by a company called Smart Technologies.

This is big business.

“Do we really need technology to learn?” she said. “It’s a very valid time to ask the question, right before this goes on the ballot.”
