    Using technology in the classroom can produce unbelievable results. But for note-taking, it may pay to keep it old-school and stick with pen and paper. Students who take notes by hand appear to process information more deeply than those who take notes on a laptop or an iPad and other technological appliances, according to a study published this year.

Using the new fashionable method generally produces more raw notes. But students using laptops tend to do worse than note-takers by hand when answering conceptual questions about the material.

Researchers from Princeton and UCLA conducted several experiments with college students watching some video lectures. In one experiment, note-takers by hand wrote down fewer words than those typing on laptops. But the two groups performed about the same when answering factual questions about the lecture material, and students who wrote longhand did much better than laptop note-takers on conceptual questions .

What gives? Students using laptops tended to write what they heard word by word rather than processing the information; that resulted in a sort of “shallower” learning, the researchers say.

In a second experiment, students taking notes on laptops were told not to write down what they heard word by word. It didn't help in spite of the instructions. They still took notes word by word and they still did worse on conceptual questions than those taking notes by hand.

In a third experiment, students were able to briefly study their notes before answering questions asked a week after the lecture. Those reviewing their longhand notes did far better than students reviewing their typed notes.

A student named Jerry from the experiment said, “The study is right, and we have to think about what was said to take the notes because I could not write down every word. I even developed complex letter symbols to help. To study for tests, I went over and underlined key points to reinforce them. The process helped me understand the lectures better.”
