问题与教学是不可分离的统一体。教学围绕着问题展开,问题在教学中得以解决,教学又发现新的问题……周而复始,推进了教学活动的开展。笔者结合教学实践谈谈初中数学教学中问题设计的几种方法。1以实验为载体进行设计说起实验,人们往往会想到物理、化学实验,而数学是一门纯理论的学科,与实验没有关系。新课程改革后,数学教学既要充分体现抽象化,又要重视具体化、形象化,很多知识都是通过数学活动或数学实践
Problems and teaching are inseparable unity. Teaching revolves around the problems, the problems can be solved in the teaching, the teaching and the new problems can be found again and again, and the teaching activities are promoted. The author combines teaching practice to talk about the junior middle school mathematics teaching problem design several ways. 1 design experiments with the carrier Speaking of experiments, people tend to think of physics, chemistry experiments, and mathematics is a purely theoretical discipline, and has nothing to do with the experiment. After the new curriculum reform, mathematics teaching should not only fully reflect the abstract, but also focus on the concrete, visualization, a lot of knowledge through math activities or mathematical practice
