中职生数学概念的学习一直比较困难,本文试从椭圆的概念教学为例,对中职生数学概念教学进行一些探索,对概念的认识上升到“对象”和“先行组织者”的理论,再升华到“再创造”的过程,来提高概念教学的效果.数学概念是数学知识的基石,在数学中占据着极其重要的地位.中职生数学能力较差,数学概念的学习一直是难点.因而,在课堂教学中,如何进行数学概念的教学,让中职生更好地理解、接受数学概念是不断探索、实践的课题.椭圆是重要的圆锥曲线,是继续学习双曲线、
The study of mathematics concept of secondary vocational school students has been more difficult. This paper tries to explore some concepts of mathematics concept teaching of secondary vocational school students from the concept teaching of ellipse. The cognition of concepts rises to “object” and “advanced organizer ”Theory, and then sublimation to “ re-creation ”process to improve the effectiveness of the concept of teaching.Mathematical concepts are the cornerstone of mathematical knowledge, occupy an extremely important position in mathematics. Vocational students math ability is poor, mathematics Concept learning has always been difficult.Therefore, in the classroom teaching, how to teach mathematics concepts, so that vocational students to better understand and accept the concept of mathematics is a constant exploration and practice of the subject.Ellipse is an important conic, is to continue Learning hyperbolic
