Khan Academy Changing Education

Khan Academy is an educational website that, as its tagline puts it, aims to let anyone “learn almost anything—for free.” Students, or anyone interested enough to surf by, can watch some 2,400 videos in which the site’s founder, Salman Khan, chattily discusses principles of math, science, and economics (with a smattering of social science topics thrown in). The videos are decidedly lo-fi, even crude: Generally seven to 14 minutes long, they consist of a voice-over by Khan describing a mathematical concept or explaining how to solve a problem while his hand-scribbled formulas and diagrams appear onscreen. Like the Wizard of Oz, Khan never steps from behind the curtain to appear in a video himself; it’s just Khan’s voice and some scrawly equations. In addition to these videos, the website offers software that generates practice problems and rewards good performance with videogame-like badges—for answering a “streak” of questions correctly, say, or mastering a series of algebra levels. (Carpenter has acquired 52 Earth badges in math, which require hours of toil to attain and at which his classmates gaze with envy and awe.)

User centred – FLIP the flip

http://usergeneratededucation.wordpress.com/2011/06/13/the-flipped-classroom-model-a-full-picture/

“Due to Khan Academy’s popularity, the idea of the flipped classroom has gained press and credibility within education circles. Briefly, the Flipped Classroom as described by Jonathan Martin is:

Flip your instruction so that students watch and listen to your lectures… for homework, and then use your precious class-time for what previously, often, was done in homework: tackling difficult problems, working in groups, researching, collaborating, crafting and creating. Classrooms become laboratories or studios, and yet content delivery is preserved. Flip your instruction so that students watch and listen to your lectures… for homework, and then use your precious class-time for what previously, often, was done in homework: tackling difficult problems, working in groups, researching, collaborating, crafting and creating. Classrooms become laboratories or studios, and yet content delivery is preserved (http://www.connectedprincipals.com/archives/3367).

A compiled resource page of the Flipped Classroom (with videos and links) can be found at http://www.scoop.it/t/the-flipped-classroom

The advantage of the flipped classroom is that the content, often the theoretical/lecture-based component of the lesson, becomes more easily accessed and controlled by the learner. Cisco in a recent white paper, Video: How Interactivity and Rich Media Change Teaching and Learning, presents the benefits of video in the classroom:

  • Establishes dialogue and idea exchange between students, educators, and subject matter experts regardless of locations.
  • Lectures become homework and class time is used for collaborative student work, experiential exercises, debate, and lab work.
  • Extends access to scarce resources, such as specialized teachers and courses, to more students, allowing them to learn from the best sources and maintain access to challenging curriculum.
  • Enables students to access courses at higher-level institutions, allowing them to progress at their own pace.
  • Prepares students for a future as global citizens. Allows them to meet students and teachers from around the world to experience their culture, language, ideas, and shared experiences.
  • Allows students with multiple learning styles and abilities to learn at their own pace and through traditional models.

One of the major, evidenced-based advantages of the use of video is that learners have control over the media with the ability to review parts that are misunderstood, which need further reinforcement, and/or those parts that are of particular interest.  (Using technology to give students “control of their interactions” has a positive effect on student learning,)

It is important, though, not to be seduced by the messenger.  Sal Khan is very charismatic and has produced good videos to explain some complex mathematical concepts.  With the growth of open education resources via Youtube and Creative Commons, it is important to note that excellent video lectures have been and are freely/easily available.  The Flipped Classroom concept, though, was not developed and articulated by Khan but by teachers such as Karl Fisch and Jon Bergman/Aaron Sams.”
