My brother-in-law finally found the article from the Scientific American Mind about multitasking has how it really doesn't happen. (Thanks, Pete!) Here is the link:

I read this and I think about the topics of our classes lately (podcasting, video streaming). Yes, offering a variety of media from which to capture the information may help this information stick in the minds of our students, but can they really process all of it in the time that we allow? I like the idea of reaching various types of learner (auditory, and visual, and tactile) with a single lesson, but are we allowing enough time? The article mentions that multiple tasks (like audio/video streaming?) can take up to one and half times longer to complete than if you concentrate on one task at a time. So I guess the big question is: is it really that much more efficient?
