      I wonder if this is the same study referenced in the National Geo article about the teenage brain.  Check this.

    Tasks performed by the volunteers involved exercises to test working memory, attentional focus, and a combination of the two. All of the subjects, who were healthy, normal volunteers, participated in all of the task groups. The task groups consisted of a control task, a delayed-response task, a dual-task, and a branching conditions task. Dual-task involves changing focus between alternative goals successively. The investigators predicted that subject performance on the individual delayed-response task and dual-task conditions would not activate the FPPC. They did predict that the branching task which involves problem solving and planning would stimulate activity in the FPPC. According to the fMRI data, their predictions were correct. The FPPC was activated only during those tasks that involved an interaction between working memory and attentional focus decisions.

      This is so true.  I like the idea of assessing what students know through a visual medium, since that's where their literacy skills lie, but my own experience is that many students don't know how to produce good visuals beyond a PowerPoint.
  • "If you're a pilot, you need to be able to monitor multiple instruments at the same time. If you're a cab driver, you need to pay attention to multiple events at the same time. If you're in the military, you need to multi-task too," she said. "On the other hand, if you're trying to solve a complex problem, you need sustained concentration. If you are doing a task that requires deep and sustained thought, multi-tasking is detrimental."

      This is common sense.

      I don't agree with this statement.  It depends on how the teacher decides to deliver the content, and it depends on what the students are doing online.

    Patricia Greenfield - look up her research at UCLA.  It's from 2009, which was three years ago at this point, so it's not the most current research.  Based on some of the sticky notes others have posted, there are some generalizations made that bare closer scrutiny.
