A new brain research shows that choosing handwriting instead of using a keyboard results in better learning and memory.
   "When you write your shopping list or class notes by hand，you simply remember what you wrote better later，" said Audrey who did the study.12 young grown-ups and12 children took part in the study.This is the first time that children have taken part in such a study.And each of them was asked to write by hand and use a keyboard with a special cap.Each examination took 45 minutes for each person.
   The results showed that the brain in both young grown—ups and children is much more active when writing by hand than when using a keyboard.According to Audrey，plenty of senses（感覺(jué)） become active by holding a pen and pushing it down on paper，seeing the letters written and hearing the sound made while writing.These build the connection between different parts of the brain，opening the brain up for learning."Learning to write by hand is a bit slower course，but it's important for children to write by hand.Students who write longer texts earlier are more motivated to write，" Audrey said.
   "If you use a keyboard，you use the same movement for each letter.Writing by hand requires control of your fine motor（精細(xì)動(dòng)作） skills，"Audrey said.
