问题是科学研究的出发点,是开启任何一门科学的钥匙。没有问题就不会有解释问题和解决问题的思想、方法和知识,问题是思想方法、知识积累和发展逻辑力量,是生长新思想、新方法、新知识的种子。在数学科的教学活动中,问题是无处不在的。对有些问题的解决,若 The problem is the starting point of scientific research and the key to opening up any science. Without question, there will be no thought, method and knowledge to explain and solve the problem. The problem is the method of thinking, the accumulation of knowledge and the logical force of development, and the seed of growing new ideas, new methods and new knowledge. In mathematics teaching activities, the problem is ubiquitous. For some problems, if
