心理学的有关研究成果表明：听和看虽然可以帮助学生获得一定的信息和学识，但远远不如动手操作给人的印象那样深刻，不如动手操作掌握得那样牢固，不如动手操作更能将有关知识转化为实践行为和能力。国际学习科学研究领域有句名言：听来的忘得快，看到的记得住，动手做更能学 The research results of psychology show that although listening and watching can help students gain certain information and knowledge, it is far less than the impression that hands-on operations give people the impression. It is not as solid as the hands-on operation. It is less effective than hands-on operations. Knowledge is translated into practical behavior and ability. In the field of international learning science research, there is a famous saying: Forget about hearing fast, remember to see it, and learn to do it better.
