As schools across the country consider which devices to invest in, they must first consider their big-picture vision for how they’ll be using these devices — and to what end. They must consider the needs of teachers and students, and come up with a shared understanding of their goals.
When it comes to choosing tablets, educators have a lot of anecdotal information to weigh, and many are making these decisions with their eyes wide open. But no one example of school tablet use can be a set model for every scenario. Each principal, each school, and each community has their own set of needs and criteria, so what might work in one school may not work in another.
A new report to be released Wednesday afternoon from the Center for Talent Innovation (CTI), the research think tank founded by economist Sylvia Ann Hewlett, finds that U.S. women working in these fields are 45 percent more likely than their male peers to leave the industry within the year.
In addition, the study also found that nearly a third of senior leaders — both male and female — who work in science, engineering and technology fields reported that a woman would never reach the top position in their company.
On Sunday, the American snowboarder Jamie Anderson won gold in Sochi’s Women’s Slopestyle event. The 23-year-old attributes her big win not just to hard work and mental focus, but also to … meditation. And yoga. And candles. And dance sessions set to Nas.
Oh, and to one more thing, too: turning off her Tinder.
Yep. The mobile hookup app—which connects people for dates or whatever else based on their geographical proximity to each other—has been, it seems, something of a distraction to the Olympians who have found themselves packed together on the shores of the Black Sea.

The overarching mistake that adults make is assuming that social media has made teens’ lives dramatically different than in previous generations. The specific anxieties or concerns ebb and flow, twist and turn. For a while, concerns about sexual predators were front and center. Then addiction, bullying, sexting, privacy. Right now, for better or worse, the media-driven anxiety is as fragmented across topics, and teens’ engagement is fragmented across services and apps.

As we approach Valnetine’s/Singles’ Awareness Day, here’s some data to chew on:
- 21% of couples have felt closer to their spouse/partner because of exchanges they had online or via text message.
- 27% of internet users in a marriage or committed relationship have an email account that they share with their partner.
- 18% of online 18-29 year olds have argued with a partner about the amount of time one of them spent online (compared with 8% of all online couples).

Education historian Larry Cuban looks at what is ethical and what isn’t in the classroom.
In my new role this year as a technology coach for the high school in which I work, I have found myself primarily involved in two separate but equally important activities: reflecting on and learning from my past challenges and successes with technology in my classroom and trying to motivate skeptical teachers to integrate technology into their classrooms.
Consequently, the following suggestions garnered from my recent experiences will hopefully provide some general ideas and guidelines to clarify the process for reluctant teachers, so they will be motivated to embrace educational technology and all of its inherent benefits.
Dennis Aabo was able to feel what was in his hand via sensors connected to nerves in his upper arm
Scientists have created a bionic hand which allows the amputee to feel lifelike sensations from their fingers.
A Danish man received the hand, which was connected to nerves in his upper arm, following surgery in Italy.
Dennis Aabo, who lost his left hand in a firework accident nearly a decade ago, said the hand was “amazing”.
In laboratory tests he was able to tell the shape and stiffness of objects he picked up, even when blindfolded.
The details were published in the journal Science Translational Medicine.
An international team carried out the research project, which included robotics experts from Italy, Switzerland and Germany.
"It is the first time that an amputee has had real-time touch sensation from a prosthetic device" said Prof Silvestro Micera from the Ecole Polytechnique Federale de Lausanne and Scuola Superiore Sant’Anna, Pisa.
The scientific advance here was not the hand itself, but the electronics and software that enabled it to give sensory feedback to the brain.
Micera and his team added sensors to the artificial hand which could detect and measure information about touch. Using computer algorithms, the scientists transformed the electrical signals they emitted into an impulse that sensory nerves could interpret.
During an operation in Rome, four electrodes were implanted onto nerves in the patient’s upper arm. These were connected to the artificial sensors in the fingers of the prosthetic hand, so allowing touch and pressure feedback to be sent direct to the brain.
Mr Aabo, 36, a property developer, spent a month doing laboratory tests, firstly to check the electrodes were functioning, and then with these fully connected to the bionic hand.
He said: “The biggest difference was when I grabbed something I could feel what I was doing without having to look. I could use the hand in the dark.
"It was intuitive to use, and incredible to be able to feel whether objects were soft or hard, square or round."
The bionic hand is still a prototype, and due to safety restrictions imposed on clinical trials, Mr Aabo required a second operation to remove the sensors.
"He is a hero," said Professor Paolo Rossini, neurologist, University Hospital Agostino Gemelli, Rome.
"He gave a month of his life and had two operations to test this device.
"We are all very grateful to him."
Prof Rossini said a lot of pre-training was done involving surgery on pigs, and with human cadavers, to ensure they knew exactly how to attach electrodes to the tiny peripheral nerves in the upper arm.
Another member of the team, Dr Stanisa Raspopovic said: “It was a very exciting moment when after endless hours of testing….Dennis turned to us and said with disbelief, ‘This is magic! I can feel the closing of my missing hand!’”
Those working in the field in the UK were also enthusiastic.
"This is very interesting work, taking research in upper limb prosthetics into the next stage by adding sensory feedback, said Dr Alastair Ritchie, Lecturer in Biomaterials and Bioengineering, University of Nottingham.
"This technology would enable the user to know how firmly they are gripping an object, which is vital for handling fragile objects - imagine picking up an egg without any feeling in your fingers."
The international team is now working on how to miniaturise the technology so that it could be used in the home.
"We must get rid of the external cables and make them fully implantable" said Prof Thomas Stieglitz, University of Frieburg, Germany, whose laboratory created the ultra-thin implantable electrodes.
Recently, scientists in Cleveland, Ohio released a video of a patient using the fingers of a prosthetic hand to pull the stalks from cherries while blindfolded. But the research has not yet been published in a peer-reviewed journal.
There is no precise timetable, but scientists think it could be a decade before a sensory feedback bionic hand is commercially available.
And they believe it may pave the way for more realistic prosthetic devices in the future which can detect texture and temperature.
'Bring it on'
But it will undoubtedly be very expensive, well beyond the means of most patients. And artificial hands still lack the precision and dexterity of the real thing.
The super-functioning bionic hand of science fiction films remains the stuff of fiction.
Nonetheless, Dennis Aabo, who now has his old prosthesis back, is ready to swap it for the bionic hand in any future trial.
"If they offer it to me, I will say bring it on, I’m ready."
As a technology director, my job is not just to keep the servers up and the network running. My job is to support and enhance technology’s potential for teaching and learning. My job is to lay the groundwork for innovation and excellence in education. If I am not taking instructional needs into account when I make decisions that impact teachers and students, I am not doing my job.
President Barack Obama is announcing commitments from U.S. companies totaling about $750 million to connect more students to high-speed Internet.
“OK, Glass … reform education.” (If only it were that easy.)
I’ve been lucky to be a member of the Google Glass Explorer Program for the past month, and this device has my attention. I was skeptical of Glass upon first hearing about the new technology, but as it developed, I began to see the potential not only in education, but also for the contemporary consumer. At this juncture, Glass is limited and very expensive. However, it has potential in what we do as educators.
