著名特级教师于漪曾说过:“课的第一锤要敲在学生的心灵上,激发起他们思维的火花,或像磁石一样把学生牢牢地吸引住。”在教学中,课堂导入显得至关重要,就像一场电影如果在一开始的时候就吸引人,那就不害怕接下来的情节不好看。因此,在教学时,教师就要抓住学生的心理特征,从一开始就抓住学生的注意力。特别是对于数学课堂而言,良好的导入方式,不仅有利于活跃课堂,还有利于提高学生的学习兴趣。 The famous teacher Yushi once said: “The first hammer of a lesson is to be knocked on the students’ mind, sparking the spark of their thinking, or attracting the students like a magnet.” In teaching, Importing is paramount, as if a movie was attractive from the very beginning, it was not scary that the next episode would not look good. Therefore, in teaching, teachers should seize the psychological characteristics of students, from the outset to seize the students’ attention. Especially for mathematics classroom, a good way to import is not only conducive to active classroom, but also help to improve students’ interest in learning.
