You might be looking for new ways to improve your understanding of something.One way to help you is to try teaching.
    Experts have been interested in the link between teaching and learning for quite some time .In the 1980s，Jean-Pol Martin，a French teacher in Germany，developed a way of teaching that asked students to teach each other.Martin taught language classes，but he went on to use his "Learning by Teaching" method（方法） in other subjects as well.
    A 2013 study also found that teaching had a strong effect （影響） on understanding and learning.An important part of the study compared the learning results of people who actually taught a lesson to those who simply prepared but did not teach."These findings show that when students actually teach the lesson，they develop a deeper understanding."the experts wrote.
    Experts have also studied the question of why teaching improves learning.A 2018 study shows that teaching may help your learning because you have to remember the information you have learned.Experts call this " retrieval." Retrieval is the act of trying to recall（回憶起）information without having it in front of you.The basic idea is that if you want to improve your memory of what you have learned，you have to practice remembering that information.While retrieval may be one reason that teaching helps learning，there could be other reasons.
    There are many ways that you can improve your learning by teaching.One way might be to teach your family or friends about something that you are learning.Another idea is to imagine yourself describing a lesson to someone.A final idea is to record a video of yourself teaching information，then send the lesson to friends or put it on some social medias.
