课堂提问是每堂课的关键。听课中我们发现一节课中教师虽提出了许多问题,但大量的是琐碎的问题,必然造成知识点的支离破碎,对于学生而言也是不必要的认知负荷。因此,我们要精心设计并提炼出一两个核心问题,核心问题是达成教学目标的关键,它能改变课堂冗长、繁琐、低效的状况。而其他的问题往往是由这个核心问题派生出来的,或与这个核心问题息息相关。抓准了核心问题,那么一节课的教学就能围绕这个核心问题来展开,学生的思维就有了聚焦点,学习的主线就清晰了。一、核心问题的特征核心问题是一节课的中心问题,其他问题都是与之存在逻辑联系的派生问题,解决核心问题 Classroom questions are the key to every lesson. During the lectures, we found that although teachers raised a lot of questions in a class, a large number of trivial questions inevitably result in the fragmentation of knowledge points, which is also an unnecessary cognitive load for students. Therefore, we must carefully design and refine one or two core issues. The key issue is to achieve the teaching goal. It can change the tedious, cumbersome and inefficient classroom. Others are often derived from this core issue or related to this core issue. Grasping the core issues, then a class of teaching can focus on this core issue to start, students have a focused thinking, the main line of learning is clear. First, the characteristics of the core issues The core issue is a lesson of the center of the problem, and other problems are the existence of a logical relationship between the derivative problem, solve the core issues
