思维从问题始。海莫斯又说:“问题是数学的心脏。”这些话都有理。试看,一个学生学习数学的全过程,一位数学家创造数学的全过程,乃至一部数学史发展的过程,不正是不断提出问题、解决问题的历史吗? 因此,善问是数学教师的基本功,也是所有数学教育家十分重视研究的问题。一个恰当面富有吸引力的问题往往能拨动全班学生思维之弦,奏出一曲耐人寻味,甚至波澜起伏的大合 Thinking from the beginning of the problem. Hemos added: “The problem is the heart of mathematics.” These words are justified. Trying to see that the whole process of a student learning mathematics, a mathematician to create the entire process of mathematics, and even a mathematical history of the development process, is not constantly asking questions to solve the history of the problem? Therefore, good question is the basic skills of mathematics teachers , But also all mathematical educators attach great importance to the issue of research. An Appropriate Face Attractive issues often give the whole class a thought-provoking chord, playing an intriguing or even turbulent encounter
