预设与生成是精彩课堂不可缺少的两个方面,预设精彩且能按期实施的课,算是成功的课;预设精彩且能不断生成的课,才算是精彩的课。教师在教学中既要关注课堂预设,也要关注学生在课堂中的发展需求,并根据互动变化产生的新情况,及时对课堂预设进行调整,不断开发和利用互动中形成的新资源,把这些新资源转化为学生的新知识和新能力。 Presets and builds are two indispensable parts of a wonderful classroom. Pre-programmed and regularly scheduled lessons are considered successful lessons. Pre-programmed and continuously generated lessons are wonderful lessons. Teachers should not only pay attention to classroom precepts in teaching, but also pay attention to the students’ development needs in the classroom. Based on the new situations resulting from the interactive changes, teachers should make timely adjustments to the classroom precepts and constantly develop and utilize the new resources formed in the interaction. Turn these new resources into new knowledge and new abilities for students.
