As arguably the world’s highest profile digital educational content offering in the world — and free at that! — with materials in scores of languages, it is perhaps not surprising that many ministries of education are proposing to use Khan Academy content in their schools.
The promise and potential for using materials from Khan Academy (and other groups as well) is often pretty clear. Less is known about the actual practice of using digital educational content in schools in middle and low income countries in systematic ways.
What do we know about how Khan Academy is actually being used in practice, and how might this knowledge be useful or relevant to educational policymakers in developing countries?
Researchers at SRI recently published the first rigorous study looking at how Khan Academy content is being used in formal educational settings as part of math instruction in the United States. Although Khan Academy originally developed as a supplemental aid in individual tutoring outside of school, it is now, in the words of SRI, “also working closely with schools to explore ways of transforming how instruction can be organized, delivered, and experienced by both students and teachers.” Some of the findings from the SRI study, which was supported by the Gates Foundation, may offer important insights into potential implementation models of relevance to middle and low income country contexts — as well as highlight where things may be a little more complicated than they may first appear. Dr. Robert Murphy, who helped lead the research team at SRI International’s well-known Center for Technology in Learning that produced the Research on the Use of Khan Academy in Schools report, stopped by the World Bank earlier this week to share some related key lessons and observations.

The SRI research study into the use of Khan Academy is quite rich in detail and contains a lot of valuable food for thought. I recommend you read it, not only for its insights into Khan Academy (which, given its widespread use and prominence, is perhaps reason alone to read the study), but also because it offers larger insights in how education technology products and services are used (and not used) in actual practice. There is no shortage of hype and nonsense about a lot of the products and ’solutions’ being marketed to education systems around the world. There is also a lot of really good and useful stuff going on. Reading and reflecting on this SRI study may help you as you try to tell the difference.
This is the first in a short series of blog posts looking at various insights emerging from the development and use of the Khan Academy as a way of exploring a number of related larger issues.

bon c’est le truc qui buzze en matière d’#enseignement en ce moment, surtout depuis que Bill Gates a décidé de le financer.

Aucune caution académique, des explications assez laborieuses et approximatives, pas des tonnes de pédagogie, la leçon sur la banque me laisse sur ma faim.
le buzz dit que les résultats sont plutôt bons en maths / physique etc, mais est plus dubitatif sur les sciences humaines ; pour des enthousiastes voir Wired ►http://www.wired.com/magazine/2011/07/ff_khan
Une sélection de ces vidéos, pour l’heure essentiellement en anglais, sera bientôt disponible en version francophone grâce à l’initiative de l’ONG Bibliothèque sans frontières. Le site, ▻http://khanacademy.bibliosansfrontieres.org, sera officiellement lancé le 4 septembre et regroupera plus de 250 leçons vidéo de mathématiques, en partenariat avec la fondation Orange.
