如果说课堂教学是一出舞台剧的话,那么课前的精心预设就是剧本的创作,没有好剧本,演员难以演得精彩。教学过程就好比是导演和演员的创作,课堂上的生成就像导演和演员的灵感,灵感来了就得好好地抓住,否则会稍纵即逝。因此,教师要及时地抓住学生有价值的生成,调整预设好的教学环节,这样就可以使预设得到升华,使课堂更加精彩。预设和生成看似是一对矛盾,其实两者是相互依存的。怎样使两者达到辩证的统一呢?笔者结合自己的教学感悟与大家共同探讨。 If the classroom teaching is a stage play, then carefully pre-class script is the preconceived creation, there is no good script, the actor is difficult to play wonderful. The teaching process is like the creation of a director and an actress. The generation in the classroom is like the inspiration of the director and the actor, and the inspiration has to be properly grasped, otherwise it will be fleeting. Therefore, teachers should promptly grasp the valuable students to generate, adjust the pre-set teaching links, so that you can make the preset sublimation, the classroom more exciting. Default and generation seems to be a contradiction, in fact, the two are interdependent. How to make the two dialectical unity? The author combined with his own teaching insights and common discussion.
