what we did was deliver the computers without preparing the teachers

the missteps may have actually widened the gap between children able to benefit from the computers and those ill-equipped to do so

Inter-American Development Bank researchers were less polite."There is little solid evidence regarding the effectiveness of this program," they said in a study sharply critical of the overall OLPC initiative that was based on a 15-month study at 319 schools in small, rural Peruvian communities that got laptops."The magical thinking that mere technology is enough to spur change, to improve learning, is what this study categorically disproves," co-author Eugenio Severin of Chile told The Associated Press

Just about all of the women in that room planned to combine careers and family in some way. But almost all assumed and accepted that they would have to make compromises that the men in their lives were far less likely to have to make.

when many members of the younger generation have stopped listening, on the grounds that glibly repeating “you can have it all” is simply airbrushing reality, it is time to talk.

I still strongly believe that women can “have it all” (and that men can too). I believe that we can “have it all at the same time.” But not today, not with the way America’s economy and society are currently structured. My experiences over the past three years have forced me to confront a number of uncomfortable facts that need to be widely acknowledged—and quickly changed.

has left our school districts impotent and, worse, has robbed millions of children of a real future

District leaders also need the authority to use financial incentives to attract and retain the best teachers.

but let's stop pretending that everyone who goes into the classroom has the ability and temperament to lift our children to excellence.

HP has just unveiled an incredibly ambitious project to create a “Central Nervous System for the Earth” (CeNSE) composed of billions of super sensitive, cheap, and tough sensors. The project involves distributing these sensors throughout the world and using them to gather data that could be used to detect everything from infrastructure collapse to environmental pollutants to climate change and impending earthquakes. From there, the “Internet of Things” and smarter cities are right around the corner.HP is currently developing its first sensor to be deployed, which is an accelerometer 1,000 times more sensitive than those used in the Wii or the iPhone – it’s capable of detecting motion and vibrations as subtle as a heartbeat. The company also has plans to use nanomaterials to create chemical and biological sensors that are 100 million times more sensitive than current models. Their overall goal is to use advances in sensitivity and nanotech to shrink the size of these devices so that they are small enough to clip onto a mobile telephone.Once HP has created an array of sensors, the next step is distributing them and making sense of all the data they generate. That’s no easy task, granted that a network of one million sensors running 24 hours a day would create 20 petabytes of data in just six months. HP is taking all that number crunching to task however, and will be harnessing its in-house networking expertise, consulting, and data storage technologies for the project.The creation of a global sensor system would be an incredible breakthrough – it could make our cities more efficient, save lives, and enable us to better understand, track, and combat climate change. As HP Labs senior researcher Peter Hartwell has stated, “If we’re going to save the planet, we’ve got to monitor it“.+ CeNSEVia Fast CompanyLead photo by Margie Wylie Comments RSS Comments RSS digg_url = 'http://www.inhabitat.com/2010/02/18/hp-invents-a-central-nervous-system-for-the-earth/'; digg_title = 'HP Invents a Central Nervous System for the Earth'; digg_skin = 'compact'; email this tweetmeme_url = "http://www.inhabitat.com/2010/02/18/hp-invents-a-central-nervous-system-for-the-earth/"; tweetmeme_style = "compact"; facebook this Related Posts

“Now I know some of you have already heard of me, but for the benefit of those who are unfamiliar, let me explain how I teach. Between today until the class right before finals, it is my intention to work into each of my lectures … one lie. Your job, as students, among other things, is to try and catch me in the Lie of the Day.”And thus began our ten-week course.This was an insidiously brilliant technique to focus our attention – by offering an open invitation for students to challenge his statements, he transmitted lessons that lasted far beyond the immediate subject matter and taught us to constantly check new statements and claims with what we already accept as fact."

while it is necessary (and possible) to teach facts to people, it comes with a price. And the price is this: facts learned in this way, and especially by rote, and especially at a younger age, take a direct root into the mind, and bypass a person's critical and reflective capacities, and indeed, become a part of those capacities in the future.When you teach children facts as facts, and when you do it through a process of study and drill, it doesn't occur to children to question whether or not those facts are true, or appropriate, or moral, or legal, or anything else. Rote learning is a short circuit into the brain. It's direct programming. People who study, and learn, that 2+2=4, know that 2+2=4, not because they understand the theory of mathematics, not because they have read Hilbert and understand formalism, or can refute Brouwer and reject intuitionism, but because they know (full stop) 2+2=4.I used the phrase "it's direct programming" deliberately. This is an analogy we can wrap our minds around. We can think of direct instruction as being similar to direct programming. It is, effectively, a mechanism of putting content into a learner's mind as effectively and efficiently as possible, so that when the time comes later (as it will) that the learner needs to use that fact, it is instantly and easily accessible.

motivation and control. One seems to need the other, apparently. Keep the students motivated and you are a great teacher in control of the learning process. But we miss the point. Motivation has a short-term effect. New things will be old again. If we equal motivation with learning we will cling too much to it and direct our best efforts (and school budget) to gaining back control. A useless cycle that can lead us to consider extremely double-edged ideas like paying students to keep them learning.

We need autonomous, self-motivated students in love with the process of how humanity has learnt.

There is a underlying idea in the framing of our questions that needs unlearning. The belief that there are "levels", layers of complexity, hierarchies that we can detect and... well, control. But wait! Isn't that the very old way we want to truly change with new technologies?

Grades serve no pedagogical function at all. (Detailed feedback does, but that's an entirely different matter.) Grading is about nothing more than efficiently communicating to other institutions the level of learning we, the teachers, estimate (and it is only an estimation) each student gained. Unfortunately, students not only want to know about the content of that communication (understandably enough) but, for many, maximizing the grade (rather than the learning itself) has become their primary goal in taking courses. If we had no grades, then students' own personal sense of learning would be all that they got out of taking courses, and they would focus on that instead. (And it would make courses a much more interesting and productive place to be.)
