How Khan Academy Is Changing the Rules of Education | Magazine - 3 views

    One teacher claims that "The idea is to invert the normal rhythms of school, so that lectures are viewed on the kids' own time and homework is done at school." - Do you agree that this is a good solution?

    That is the way a couple of my colleagues (science and math) use Khan and they feel it creates more opportunity to use them as a resource for their specific needs. The spend some time at the beginning of class to answer questions as a group and then students begin working on problems and asking for individual help during class.

    I think the idea of distributing video tutorials and courseware for free is a powerful lever for change and education (Khan Academy, MIT OpenCourseWare, etc). While I'm intrigued by Khan Academy and see the benefit to help student who want to pause and replay lessons, there is a limit to it's use as an educational tool. In the article linked below, the Los Altos district currently piloting the program noted that they have not seen any statistical difference between Khan students and the control group. http://losaltos.patch.com/articles/school-district-expands-khan-academy-to-all-schools

    I too am intrigued by this "inverting" of time spent in the classroom and at home. My idealized model would be to introduce learners to new material at their own pace out of the classroom (allowing for pausing, note taking, reflecting and/or rewinding) and focus classroom time on face to face guiding and coaching of clusters of students or individual students engaged in applying or exploring the current material. To help facilitate this (and assist with accountability) some brief form of pre-assessment before class or at the start of class could illuminate for student and teacher alike what material has been mastered and what needs more attention. The research report from the TIE Foundations summer reading appears to support this type of hybrid approach. => Marsha Lovett, Oded Meyer, and Candace Thille (2008).

    An added benefit of tools such as Khan Academy is the option for reinforcement. In a traditional K-12 school environment students do not have the option to watch a video of their class or spend personalized time reviewing a concept they need more time with during class time due to the required pace of school curriculum. An online learning tool allows a student to watch a lesson as many times as needed and to learn from an expert. Often if a student needs help outside the classroom the only people they turn to is parents, who may or may not know about the content themselves.

Libraries begin to rent out e-books - 0 views

    More fears of publishers who hold the rights to intellectual property. Folks, you think health care is a big debate? Wait until our patent system changes - that will be a gladiator battle with everyone in the world (free and not free) participating... "As digital collections grow, Mr. Sargent said he feared a world in which "pretty soon you're not paying for anything." Partly because of such concerns, Macmillan does not allowits e-books to be offered in public libraries. Simon & Schuster, whose authors include Stephen King and Bob Woodward, has also refrained from distributing its e-books to public libraries. "We have not found a business model that works for us and our authors," said Adam Rothberg, a spokesman."

µTorrent 3.0 - µTorrent - a (very) tiny BitTorrent client - 2 views

    Does anyone have any experience with this tool. It looks like a very interesting example of a Intelligent Web Filtering. Wow! Good side is that this is like Tivo for the web. Bad side is that you better have nothing else to do but look at the web. Also an interesting take on Personal Learning Networks.

    I am familiar with BitTorrent, and it's interesting Chris that you came about it excited for its uses in education. But have you read or heard about the controversy surrounding it? In a nutshell- BitTorrent is a technology that allows large collections of files and data to be shared across the internet in a decentralized, peer-to-peer manner. A person who has the original files decides to share them via BitTorrent, so others can download from him/her. But as the others begin downloading the files, they also start sharing the pieces they've downloaded with the ever-growing set of new users asking for the file. BitTorrent works like a growing web- in order to download files shared via BitTorrent - you have to share the pieces you get with others. More downloaders = more uploaders as well, ensuring popular files will always be accessible. The benefits - this is cheap and decentralized, no need to pay to host the files on the web. The users who have the file are sharing the file from their own computers with others requesting it. And this can be permanent - if you host a BitTorrent to share a file, you have that sharing channel last forever (not relying on external services that cost $ or can be shut down).

    BitTorrent is a really powerful technology that allows large amounts of files and data to be shared quickly with a limitless number of people. It's scalability at no cost. Could be a great tool for educators to share content across the globe in a hassle-free way. Even the folks at Khan Academy are excited to use it: from: http://blog.vipeers.com/vipeers/2008/10/bittorrent-is-a.html "For Khan Academy, BitTorrent was a natural extension for it stated mission of "a world-class education for anyone anywhere," Sal Khan tells Fast Company. Kahn was excited for activist educators to be able to download the Academy's entire portforlio, burn it on a CD, and distribute it to rural or underdeveloped areas otherwise unable to access it without a broadband connection. "I think the single most fun thing about BitTorrent," Khan adds, "is this content will never die. A nuclear bomb could hit our offices tomorrow and could take down our servers, but its going to sitting somewhere in the world on somebody's server." He added, "We don't care about monetizing the content; we just care that it gets used."

    But despite the prospects of BitTorrent being a great technology to allow sharing of digital content freely, to allow downloading of vast amounts of data that can then be stored offline and shared with anyone... the rest of the article (http://blog.vipeers.com/vipeers/2008/10/bittorrent-is-a.html) mentions that Google was unhappy with Khan's decision to use BitTorrent. Google actually blacklists BitTorrent content from its searches, and so is actually blacklisting Khan Academy content, despite being a recent financial backer of Khan. Why? This is the controversy: BitTorrent's power to share digital content in a decentralized way, where the more popular a file is, the faster it'll spread-- has led it to become the most popular method of digital piracy out there today. This has quickly become the most common use of BitTorrent, far exceeding the sharing of legitimate digital content. It's become a nightmare for the movie, music, software, and video gaming industries. A summary of the legal issues surrounding BitTorrent: http://en.wikipedia.org/wiki/Legal_issues_with_BitTorrent

    Hey Bharat, I am so glad I asked. I had no idea. Very interesting. New dimension to the concept of free knowledge vs. intellectual property. I think the kids at my school are using this to share music. I'll have to check it out. I find this conflict- "Google actually blacklists BitTorrent content from its searches, and so is actually blacklisting Khan Academy content, despite being a recent financial backer of Khan. " so intriguing. At first glance it looked to me like a vision of networked learning that was aimed at an authentic task with authentic participants (as portrayed by actors :).
