所谓变式教学,是指教师在引导学生理解数学概念或解决数学问题时,从不同角度、不同层次、不同情形、不同背景作出有效的变化,而其本质特征却不变的一种教学方式.在高中数学课堂上,如果能恰当地运用变式教学,有助于学生对数学知识的理解和掌握,也有利于激发学生的求知欲,使学生主动地参与教学的全过程.这对提高学生的思维能力,应变能力和创新意识大有益处.本文结合个人的教学实践,介绍了变式教学在高中数学
The so-called variant teaching, refers to the teacher in guiding students to understand the concept of mathematics or solve mathematical problems, from different angles, different levels, different situations and different backgrounds to make effective changes, but its essential characteristics are not changed a teaching method. In high school mathematics classroom, if the proper use of variant teaching, help students understand and grasp of mathematical knowledge, but also help to stimulate students’ curiosity, so that students take the initiative to participate in teaching the whole process.This is to improve students Thinking ability, adaptability and innovative awareness of great benefit.This paper combines personal teaching practice, introduced the variant teaching in high school mathematics
