A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops(笔记本电脑)．
Students are increasingly using laptops for notetaking because of speed and legibility(清晰度)．But the research has found laptop users are less able to remember and apply the concepts they have been taught.
Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes“mindlessly”by taking down word for word what the professors said.
In the first experiment，students were given either a laptop or pen and paper.They listened to the same lectures and were told to use their usual notetaking skills.Thirty minutes after the talk，they were examined on their ability to remember facts and on how well they understood concepts.
The researchers found that laptop users took twice as many notes as those who wrote by hand.However，the typists performed worse at remembering and applying the concepts.Both groups scored similarly when it came to memorizing facts.
