Okay, I'm for making learning more interactive as much as the next person, but I think this proposal in an otherwise interesting post by Dr. Trent Batson in Campus Technology - Tipping Point for "Content"--Dynamic Interaction, Not Static Stuff - is taking immersion a little too far.
Or a class discussion carried on in a chat room (while in a real classroom) so students can interact with each other as much as with the teacher.
Why would anyone want to have learners who are gathered together in a real classroom carry on their discussion through an online chat room? I have a difficult time getting around the vision of a room full of learners all studiously clicking away at their i-Phones, laptops, etc. without a word being said.
About the only value that I can see from this exercise is that it creates a record of the conversations through the chat room log. If that's what a teacher wants then just buy a digital tape recorder.
