There are some trends in e-learning right now although I wouldn’t call them technologies. They are just slightly different ways of using existing technology.
They include gamification, big data (analyzing it and then figuring out how to use it), adaptive/personalized learning, microlearning, MOOC’s, API’s to enhance interoperablity, etc.
I believe that it will take a long time for the education and training community to adopt the latest buzz technologies like virtual reality, GPS, beacons, 3D printing, etc. in any major way.
