人们常说:“良好的开端是成功的一半。”一堂精彩生动、美不胜收的数学课宛如一支沁人心脾的乐曲,“起调”引人入胜,“高潮”跌宕多姿,“尾声”回味无穷。其中“起调”部分,也就是数学课堂中的新课引入,更是起着至关重要的作用。教师要提高课堂教学的实效,把握住课堂的主线,必须设计好课堂的引入部分。本文就高中数学教学中,如何设计精彩的新课导入,提高数学课堂的教学效益,略谈一点自己的浅见,与同行共享。一、复习旧知,做好铺垫,水到渠成数学是最富逻辑性的学科,也是众多学科中新旧知识
It is often said that “a good start is half the battle.” “A wonderful, vivid and beautiful mathematics lesson is like a refreshing piece of music,” “a tune-up,” “a climax,” an ups and downs, End “memorable. Among them, the part of ”adjustment ", that is, the introduction of the new lesson in the math classroom, plays a more crucial role. Teachers to improve the effectiveness of classroom teaching, grasp the main line of the classroom, we must design the introduction of the classroom part. This article on high school mathematics teaching, how to design exciting new course to import, improve the teaching efficiency of mathematics classroom, a bit of my own humble opinion, sharing with peers. First, the review of the old knowledge, to pave the way, into a matter of course Mathematics is the most logical discipline, but also many disciplines of old and new knowledge
