A little while ago I posted a survey of VLE usage, and today I stumbled upon this survey result set from 2011:
I don’t know much about the context of this, other than that it was created by Matt Lingard.
I consolidated the data from 'Pivot Table 2' and turned it into a helpful pie chart. Chamilo was a new one to me, but seems to be very popular in South America with some pockets of adoption in Belgium and France, in 2011 at least.
I’d like to see or conduct a similar survey to assess the situation now, but don’t really have any justification beyond curiosity. Maybe next time I’m involved in a VLE review.
