高中新课程标准明确指出,在高中数学概念的教学中,一定要注意通过揭示数学知识如何发生、如何发展的过程,引导学生理解数学知识的本质。事实上,会求、会解、会运算并不能说明真正理解数学知识的本质,更不能说明理解了概念,这就提示教师要重视数学概念的教学过程,而概念教学过程中一些环节的缺失影响了学生建构概念的丰富性和全面性。美国教育家杜宾斯基针对数学学科的学习提出了 New high school curriculum standards clearly pointed out that in the teaching of high school mathematics concepts, we must pay attention to by revealing how mathematics occurs, how the process of development, and guide students to understand the nature of mathematical knowledge. In fact, seeking, understanding, and calculating does not explain the true understanding of the nature of mathematical knowledge, but can not explain the concept of understanding, which suggests that teachers should pay attention to the mathematical concept of the teaching process, and some missing links in the concept of teaching process The concept of student construction richness and comprehensiveness. American educator Dubinsky proposed for the study of mathematics
