Wolfram|Alpha: a new way to find data online? - SciTechBlog - CNN.com Blogs - 0 views

  •  
    Say you're an investor and you want to see how two companies are faring against each other on the market. You could type in "IBM versus Apple" and Wolfram|Alpha will generate graphs and tables to compare the stocks over time. It also give you the Web-based sources used to generate the data, so you know where the numbers are coming from. The site also solves equations and shows the steps it took to do so, which will be of interest to high school students and math majors. Not into number crunching? If you live near the coast, you could type in "tides in ____" and find charts of tidal and lunar information. You could also graph that against other cities, which would be cool if you're a surfer. The site is also interesting for academic queries. Type in "Internet users in Africa" and you'll get the total number of Web users there - 51 million - as well as lists of the number of users by country plus graphs of this information. If you're in the fisheries business, or if you're an environmentalist, you could type in "fish produced in Italy versus France" to get an idea of how that sector is faring. The answer includes specifics, like how much of the fish crop was farmed versus what was captured. Such data could be used to argue policy points or to debate whether or not certain industries are sustainable.

Noteflight - Sign In - 2 views

  •  
    We built Noteflight because we looked at where software is today, and saw that applications for writing music were stuck in the past. We wanted to accomplish a few important goals: Make it easy to create and share written music online. People who make music -- amateurs and professionals, students and teachers -- want to share that music with others, sooner or later. But most software for working with notated music treats the Internet as an afterthought: it's geared to saving your music on your own computer's hard disk, not to sharing your music with other people. It's painful to share musical scores online today, and as software inventors, we knew how much better it could be. People expect to be able to do their creative work wherever they go, and a crop of new browser-based applications make it incredibly easy to create and publish word-processing documents or spreadsheets online. We feel musical documents should be just as accessible. Empower developers to build a new world of musical and educational applications. Applications today should be not only powerful tools, but building blocks that can be combined in ways that their creators have never foreseen. A truly powerful musical application should be extensible without having to open it up and change the code. Adding new instruments and symbols, or embedding in a page and building new kinds of connections with other content -- all of these things should be possible. A great tool lets creative people not only use its built-in capabilities, but extend them and freely reorganize them in new ways. As Bertrand Meyer, a pioneer of software thinking, once put it: "Real systems have no top". Encourage a vibrant community of users by keeping the basics free. Music notation software vendors continue to charge high prices for boxed software, CD and DVD distribution media, and printed manuals. Then once you buy something, you're basically stuck with it until the next major upgrade cycle comes around, at which point you pa

Empowering middle schools through technology - Ideablob: where ideas grow - 1 views

  •  
    In ten years, modern education will have fully integrated new classroom media: video, online collaboration, and other web tools. We hope to pioneer a web tool that is a platform for this new media, bringing the power of the web to students, teachers, and parents in a secure, innovative environment. Our idea is a response to problems in schools that we have identified through primary research and user involvement. The way students, parents and teachers interact and learn in middle schools has many opportunities for growth and improvement. Here is one example:Research shows that in the last ten years the way people obtain and digest information has changed, incorporating tools like the web. Unfortunately, the classroom environment has not kept pace with this aggressive expansion of technology as a social, educational and communication tool. We hope to provide the tools to solve this and other problems in the middle school context. Read more at AlightLearning.com

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.”
  • ...5 more annotations...
  • 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."

Oxytocin: the direct route to altruism? - 0 views

  •  
    "In relation to our previous and well-visited post about oxytocin, we should mention a new study that uses this very substance in a neuroeconomic set-up. In the study, recently published by Neuron, and headed by Baumgartner et al., it was found that the administration of oxytocin affected subjects' in a trust game. In particular, it was found that subjects that received oxytocin were not affected by information about co-players that cheated." (BRAINETHICS)

The Tower and The Cloud | EDUCAUSE - 0 views

    The emergence of the networked information economy is unleashing two powerful forces. On one hand, easy access to high-speed networks is empowering individuals. People can now discover and consume information resources and services globally from their homes. Further, new social computing approaches are inviting people to share in the creation and edification of information on the Internet. Empowerment of the individual-or consumerization-is reducing the individual's reliance on traditional brick-and-mortar institutions in favor of new and emerging virtual ones. Second, ubiquitous access to high-speed networks along with network standards, open standards and content, and techniques for virtualizing hardware, software, and services is making it possible to leverage scale economies in unprecedented ways. What appears to be emerging is industrial-scale computing-a standardized infrastructure for delivering computing power, network bandwidth, data storage and protection, and services. Consumerization and industrialization beg the question "Is this the end of the middle?"; that is, what will be the role of "enterprise" IT in the future? Indeed, the bigger question is what will become of all of our intermediating institutions? This volume examines the impact of IT on higher education and on the IT organization in higher education.

    Imagine collecting all the best free educational videos made for children, and making them findable and watchable on one website. Then imagine creating many, many more such videos. Just think: hundreds of thousands of great short videos, and other media, explaining every topic taught in schools, in every major language on Earth. Finally, imagine them all deeply and usefully categorized according to subject, education level, and placed in the order in which topics are typically taught. WatchKnow--as in, "You watch, you know"--is trying to do this.

2 | When The Internet Is Your Brain: - 8 views

  •  
    In H+: The Digital Series, a post-apocalyptic techno-thriller that debuts today from producer Bryan Singer (The Usual Suspects, X2, House), a consumer device that allows people to stay connected 24-hours a day directly results in the demise of one-third of the Earth's population. That's a scary vision for any epoch, but perhaps especially one currently salivating at the prospect of new iThings. The culprit in H+, which is shorthand for a real-world movement called transhumanism, is a wonder chip that we implant in our brains, thereby eliminating the need to hunch over physical electronics forever. But the price paid for this technological leap is a steep--when a global virus strikes the implants, the system failure is fatal.

Stimulating Critical Thinking through a Technological Lens - 15 views

  •  
    Stimulating critical thinking using technology has the potential to create more in depth understanding of science and math content by students when engaged in learning activities which integrate in-class and on-line technology resources. Technology tools support stimulation of both inquiry-based and critical thinking skills by engaging students in exploring, thinking, reading, writing, researching, inventing, problem-solving, and experiencing the world outside their classroom. This is accomplished through learning content through the lens of video to multimedia to the internet (Using Technology to Improve Student Achievement, NCREL, 2005).

Twitter Your Lesson Plans » TeachEng.us - 0 views

  •  
    How about a quick lesson plan? How abouttwitter.png a way to keep a shorthand record of daily class activities? Then how about twitter? Start a Twitter profile (a separate one just for teaching, so not to annoy your friends), and at the end of each class day jot down what you did in class (see below for my Monday, Feb. 11th). Networking with other subject area teachers will encourage collaboration on similar lessons. And possibly (though we teachers would hope not in a 1984 kind of way), an administrator could link in and keep tabs. If I were a curriculum person in an administration, the first thing I would do would be to set up accounts for each teacher to post one daily update.

O'Reilly Network -- What Is a Wiki (and How to Use One for Your Projects) - 0 views

  • A wiki is a website where users can add, remove, and edit every page using a web browser. It's so terrifically easy for people to jump in and revise pages that wikis are becoming known as the tool of choice for large, multiple-participant projects. In this Article: Wikis Work for Big Projects Choosing a Wiki Advantages to Using a Wiki Disadvantages to Using a Wiki Using a Wiki Somewhere, in a dimly lit classroom, a library bench, or in a home study, some lucky so-and-so is writing an essay from beginning to end with no notes. This splendid individual is able to craft entire sections without forgetting by the end what the section was intended to include at the beginning, and can weave a carefully paced argument with thoughts and references collected over a period of months, all perfectly recollected. Neither of your authors is this person. Instead, we need help, and that help comes in the shape of a wiki. A wiki is a website where every page can be edited in a web browser, by whomever happens to be reading it. It's so terrifically easy for people to jump in and revise pages that wikis are becoming known as the tool of choice for large, multiple-participant projects.
