所谓的课前铺垫题,就是学生学习新知前需要解答的练习题。设计铺垫题的目的是为了减缓旧知与新知之间的梯度,使学生更容易、更透彻地理解新知内容,起到搭桥铺路、抛砖引玉的作用。这些铺垫题都是学生以前所掌握的知识,或通过直接观察就能得出答案的。 The so-called pre-school bedding questions, is that students need to answer new exercises before learning exercises. The purpose of designing bedding is to slow down the gradient between old knowledge and new knowledge, to make it easier and more thorough for students to understand the content of new knowledge and to play a bridging role in bridging the gap. These bedding questions are the students’ past knowledge, or can be answered by direct observation.
