My own personal experience is that typing is far more effective for me than writing: I cannot read my own handwriting after taking notes during a lecture or conference presentation. This is the reason why I started carrying around an iPad and using Evernote to jot down notes. In addition, it is way easier to search for notes when it is organized by something like Evernote. When I started to type to take notes I found that it improved the conversation within my own mind with the material being presented. Hand-writing notes I found I became too worried about the quality of my handwriting so that I could read it later! :P
When I type my notes I am not transcribing what the speaker is saying. Rather, my typing is writing to think. And I think that is the important point to impress on students - note-taking is not transcribing. Note-taking is writing to think not thinking to write. My typing is my form of writing which is my way to think. I believe that this should be the take home message to students: Don't think about writing - write to facilitate your thinking. If approached this way it becomes clear that transcribing a lecture or presentation is not thinking, and this is the reason, I think, that many typists do not do well on subsequent quizzes - they haven't been thinking while they type on their laptop.
So I think one of the comments posted to The Chronicle blog-post is correct; it depends on the typing and handwriting skills of the particular student. And, of course it depends upon the level of engagement the student brings to the lecture.
I wonder if this issue will be moot in a few years when we are all using active learning strategies in our classrooms and rarely lecturing?
