常言道:良好的开端是成功的一半。在数学课堂教学中也是如此,无论是新授课,还是复习课、练习课……往往开了个好头就等于成功了一半,尤其在数学公开课上,对于陌生的教学环境、陌生的学生,此时师生的内心都是忐忑的,如何在课前短短的几分钟内,消除陌生感,拉近彼此的距离,营造出好的氛围,达到“课未始,趣已生”的境界……这时一个巧妙的课前互动开场就显得尤为重要,有效的课前互动,就是开启一节精彩数学课的金钥匙。
As the saying goes: a good start is half done. In mathematics classroom teaching is also true, whether it is new lectures, or review classes, practice class ... ... often give a good head is equal to half the success, especially in open mathematics classes, for unfamiliar teaching environment, strange students, At this point, the hearts of teachers and students are shy. How to eliminate the strangeness and shorten the distance between each other in just a few minutes before the class so as to create a good atmosphere and reach the goal of “not getting started with class” Realm ... ... At this time an ingenious pre-class interactive opening is particularly important, effective pre-class interaction, that is, open a wonderful mathematical lesson of the golden key.
