Students who took notes with the laptops slightly out-performed the students who wrote their notes longhand (with pen and paper) when it came to recalling specific facts. But when it came to conceptual understanding, the students who took notes by hand performed much better.
At the end of the day, it seems as though what’s most important is that however you take your notes, you phrase them in your own words, and take the time to really engage with and assess your understanding of the concepts as you’re writing them down, rather than simply transcribing everything you’re learning verbatim.
