The Khan Academy: MOOC meets the flipped classroom

The Khan Academy is innovating education, taking lessons out of the classroom, establishing mastery, and maximizing technological potential. The academy is a not-for-profit organization hosting an extensive video library on hundreds of subjects at various levels of complexity. Access to the clips is available via the organization’s site or on the academy's You Tube page.

This approach incorporates the concepts behind MOOCs,  massive open online courses, and the flipped classroom.  In Khan Academy’s method learning happens on the student’s time and online, interactive time is used to practice methods and co-teach. All lessons are free and self-paced where mastery is the ideal goal, but does not necessitate all students move at the same pace as in a traditional classroom. Khan Academy’s methods allow for infinite variation among students to achieve mastery level. An October 2nd article in Slate Magazine by the academy’s founder, Salman Khan (2012), explicates his belief in this system; he explains Khan Academy is a learning method for the future because it incorporates educational technology with high-quality teaching while maintaining such a low cost that the information is available to a wide audience.


Later in October, Wired Magazine ran a piece about one of Khan Academy’s teachers, Vi Hart, a self-proclaimed mathemusician. Although not trained in mathematics, Ms. Hart incorporates her passion for math with a penchant for music and catchy summary. However music is not her only means of conveyance. In a short You Tube clip on her website, Ms. Hart illustrates the Mobius Strip and symmetrical properties of a popular childhood candy treat: Fruit by the Foot.

Despite the media buzz, including laud in 2010 from Bill Gates, founder of Microsoft, and from Businessweek last year, Khan Academy has experienced some criticism in 2012.  A short series from July in the Washington Post by Valerie Strauss highlights some shortcomings of the academy’s methods, primarily focusing on a lack of rigor in the math videos produced by Salman Khan, the academy’s founder.  In some instances, Khan completely gets the math lesson wrong.

The debate surrounding Khan Academy remains pitted on whether or not Khan is a good teacher. No one debates the selflessness of offering free, online courses or the academic research-based focus on self-paced mastery; those are in line with current educational thinking. But how effective can a tool be when the experts in a subject make mistakes, which is not a terrible end, but then refuse to engage in a rational dialog to come to a consensus? Instead of focusing the debate on how to improve teaching and learning, the Washington Post instead deemed it more important to feature an argument between two experts. Further no one has made mention of how this potentially positive technology can be adapted or made available to those without internet connectivity or access to computing devices.

  1. I agree with some of the criticism that some of the videos are not very good, which may have an adverse effect on the learners. Khan's innovative ideas on offering such an intensive video library is of great help to those in need. However, education, especially scientific subjects, requires great extent of accuracy. Therefore, some criticized videos should be modified. I also support his ideas as The Washington Post by Valerie Strauss suggests that we have to recognize the good then cultivate it. Today there are many learning websites created by dedicated teachers, and I think it is time for the education sector to have some kind of providing quality instructions or accreditation so as to make the good become better.

  2. Thanks for your response. Do you think it is feasible for online courses and programs to be accredited in the same way as traditional university courses, or will an alternative accreditation process need to be developed?

    1. I agree that Khan Academy has been a game-changer in the delivery of online education, particularly in specialist areas like mathematics and the sciences. It can rightly claim to be a precursor for many online courses these days. Through personal experience, I can say that the site has developed well over the years, and has attempted to add new features like badges (based on performance) and additional practice exercises to attract (and retain) learners.

      As to Cathryn's comment about accreditation, this is something the online education world has been thinking a lot about recently. With online courses mushrooming rapidly, including those by established universities, the integrity of the examination needed to certify the completion of a course has emerged as a crucial element. This has led to the concept of online proctoring (you could read my post Online Proctoring on this topic for details).

      The issue of accreditation will gain more currency with the emergence of the likes of the Minerva Project, which promises to deliver a full four-year university course online from 2015.

    2. I am just reading about Minerva - wow. I feel inspired from what I've read, but I'm also interested to see how the project distinguishes itself from other online offerings! Thanks.
