If one has a tablet with microphone and software that can incorporate audio from user with same into a “learning app”…… that then creates another layer of interaction for designing effective DLE.
This supporting documentation, and this link to a recorded version of a webinar, discuss some of how that might work using Siri and a iPad during a DLE.
(admin: the webinar uses blackboard, which has recently been problematic to use on a Mac with these webinars… have to download a version of Java here that MacOS X will accept. FWIW, haven’t as yet got it all working on my 10.8.4 OS install.)
