Do people have better recall when they type notes, or when they write them? A study cited in The Chronicle found that students who wrote their notes had much better recall. It seems like the study was somewhat limited in its sampling, but still not a surprise. “In a series of studies, the researchers provided students with laptops or with pen and paper to take notes. (The computers were disconnected from the Internet.) Students were then tested on how well they could recall facts and apply concepts. During the first test, students were told to “use their normal classroom note-taking strategy.” Some typed, and others wrote longhand. They were tested 30 minutes later.”
