"Real Life Learning: An Up Close Look at Competency-Based Education," by Edsurge, with sponsorship from D2L. There is no disclosure on the landing page for the guide (nor on individual articles in it) that the two companies share investors: Graham Holdings.

I have been tracking these failures to disclose financial relationships because Edsurge has been selling its Concierge service to schools in order to help them buy ed-tech products. The lack of transparency is important, I think. Now Edsurge says it's ending the service, but I'm still going to keep track on the publication's disclosure issues.
