Even though they’ve been around since the 1500s, it may still be too soon to give up pencils and handwritten notes.
Students who take notes on a laptop may take more notes than those who write by hand, but more isn’t always better:
New research by Pam Mueller and Daniel Oppenheimer demonstrates that students who write out their notes on paper actually learn more. . . . As in other studies, students who used laptops took more notes. In each study, however, those who wrote out their notes by hand had a stronger conceptual understanding and were more successful in applying and integrating the material than those who used took notes with their laptops.
There’s much more at the linked article, and the result looks pretty robust after several different studies. I don’t have any policy against laptops in the classroom (and don’t plan to, either), but you might want to consider whether your laptop is really helping you.
