法国作家卢梭说过:“榜样!榜样!没有榜样,你永远不能成功地教给儿童以任何东西。”喊破嗓子不如做出样子,所以说教师是旗帜,学生如影随形地追着走;教师是路标,学生毫不迟疑地顺着标记前行。也就是说,在一个你完全陌生的领域里,如果没有任何的引领,你几乎创造不出一点成绩来。很多时候,人们所学到的知识和技能都是从模仿开始的。模仿前一定会有一个人有意或无意间做过示范,模仿者根据需要或感兴趣而进行模仿,通过多次操作、体会,达到熟练,有能力者通过改进,创造出适合自己的独有的技能。所以说,教师的示范作用很有必要,忽视了这一点,会阻碍学生的正常发展。 The French writer Rousseau has said: “An example! An example is that you can never teach a child everything successfully.” "Calling a broken throat is not as good as making a appearance, so teachers are flags and students are chasing after each other. Teachers are signposts and students follow the mark without hesitation. In other words, in a totally strange area, you can barely accomplish anything without any direction. Very often, people learn the knowledge and skills are from the imitation of the beginning. There must be a person intentionally or unintentionally before the imitation to do a demonstration, imitators according to need or interest in imitation, through many operations, experience, to achieve proficiency, ability to improve, to create their own unique skills . Therefore, it is necessary for teachers to play a demonstrative role. Ignoring this point, they will hinder the normal development of students.
