随着时代的不断发展,我国新课改已越来越重视从全面、持续的角度去关注学生的发展,即要求学生借助相关数学的方法和技能去形成属于自己的学习思想,让学生能够熟练地借助数学知识去解决现实生活中的实际问题。为了更好地达成这一目标,教师就要积极地将数形结合的思想应用到实际的教学中去,努力发挥教学上的相互渗透、交叉作用。数学是研究和揭示数与形之间联系的学科,可以说数与形之间的矛盾及统一正是促使数学发展的重要内因,著名数学家华罗庚就曾经说过:“数缺少形时则少直觉,形缺少数时则难入微。”由此可见数形结合思想在数学教学中的重要性。为了更好地提高学生的数学素养、推进课程的发展,在此,本文就将以如何更好地在初中数学教学中应用数形结合思想为主要内容,进行相应的策略探究。
With the continuous development of the times, the new curriculum reform in our country has paid more and more attention to the development of students from a comprehensive and sustained perspective, which requires students to form their own learning thoughts through the relevant mathematical methods and skills so that students can be skilled Use mathematical knowledge to solve practical problems in real life. In order to achieve this goal better, teachers should actively apply the idea of combining numbers and forms to actual teaching, and try to exert their mutual penetration and interaction in teaching. Mathematics is a discipline that studies and reveals the connection between numbers and forms. It can be said that the contradiction and unity between numbers and forms are the important internal factors that promote the development of mathematics. The famous mathematician Hua Luogeng once said: “ Less intuition, the shape of a small number is difficult to find. ”This shows how the combination of mathematical ideas in mathematics teaching. In order to improve students’ mathematical quality and promote the development of the curriculum, this article will explore how to apply the theory of number combining in mathematics teaching in junior middle school as the main content.
