What Principals Must Know About Information Technology - 20 views

  •  
    KUTZTOWN, Pennsylvania - They're being called the Kutztown 13 - a group of high schoolers charged with felonies for bypassing security with school-issued laptops, downloading forbidden internet goodies and using monitoring software to spy on district administrators. You must think of your building's digital information in the same manner that you consider the overall building security and tests being locked in the school safe. One analogy is: To know what 'digital doors' information is behind and who has the 'digital keys' to those doors.

PiNet, A system for setting up and managing a classroom set of Raspberry Pis. - 17 views

  •  
    PiNet allows you to cluster Raspberry Pi computers in your classroom, monitor each of them, and allows students to share their work on a PiNet connected display. Given the low price of Raspberry Pi and the fact that this tool is free it seems illogical for a classroom not to have this setup.

Medical devices powered by the ear itself - MIT News Office - 1 views

  • Health Sciences and Technology (HST) demonstrate for the first time that this battery could power implantable electronic devices without impairing hearing.
  • The devices could monitor biological activity in the ears of people with hearing or balance impairments, or responses to therapies. Eventually, they might even deliver therapies themselves
  • “In the past, people have thought that the space where the high potential is located is inaccessible for implantable devices, because potentially it’s very dangerous if you encroach on it,” Stankovic says. “We have known for 60 years that this battery exists and that it’s really important for normal hearing, but nobody has attempted to use this battery to power useful electronics.”

  • The ear converts a mechanical force — the vibration of the eardrum — into an electrochemical signal that can be processed by the brain; the biological battery is the source of that signal’s current. Located in the part of the ear called the cochlea, the battery chamber is divided by a membrane, some of whose cells are specialized to pump ions. An imbalance of potassium and sodium ions on opposite sides of the membrane, together with the particular arrangement of the pumps, creates an electrical voltage.
  • Low-power chips, however, are precisely the area of expertise of Anantha Chandrakasan’s group at MTL
  • The frequency of the signal was thus itself an indication of the electrochemical properties of the inner ear.
  • in cochlear implants, diagnostics and implantable hearing aids. “The fact that you can generate the power for a low voltage from the cochlea itself raises the possibility of using that as a power source to drive a cochlear implant,” Megerian says. “Imagine if we were able to measure that voltage in various disease states. There would potentially be a diagnostic algorithm for aberrations in that electrical output.”
  • “I’m not ready to say that the present iteration of this technology is ready,” Megerian cautions. But he adds that, “If we could tap into the natural power source of the cochlea, it could potentially be a driver behind the amplification technology of the future.”
  •  
    "For the first time, researchers power an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear."

    "All of D-Lab's classes assess the needs of people in less-privileged communities around the world, examining innovations in technology, education or communications that might address those needs. The classes then seek ways to spread word of these solutions - and in some cases, to spur the creation of organizations to help disseminate them. Specific projects have focused on improved wheelchairs and prosthetics; water and sanitation systems; and recycling waste to produce useful products, including charcoal fuel made from agricultural waste."

Monitoring and Evaluation of ICT in Education Projects | infoDev.org - 0 views

  •  
    This short handbook provides guidance for policymakers struggling with two key issues: (1) What is the impact on student achievement of introducing ICTs in educational settings in developing countries? (2) How should this impact be measured, and what are the related issues, especially as they relate to Education For All and other Millennium Development Goals?
