数学教学是一门需要不断创新的艺术,低年级学生在数学学习中经常会遇到不能理解的难点,若不突破,学生对方法的理解永远只能停留在一知半解的层面上,大大增加了错误率。因此低年级学生的成绩差距往往并不是刻苦的程度与智商的差异,而是对难点理解的不透彻,没有掌握方法的本质。难点教学是教学活动中难以攻破而又必须攻破的堡垒,同时又正是发展学生思维能力,提高学生数学素质的重要资源,更是检验和磨砺教师教学水平的试金石。一、改变思维方式,触类旁通,突出差异 Mathematics teaching is an art that requires continuous innovation. The students in lower grades often encounter difficulties that can not be understood in maths learning. If they do not break through, the students’ understanding of the method will always stay at the level of perplexity and greatly increase the mistakes rate. Therefore, junior high school students’ performance gap is often not the difference between the degree of hard work and IQ, but the lack of understanding of the difficulties, did not grasp the essence of the method. Difficult teaching is difficult to break through the teaching activities but must be broken fortress, at the same time it is the development of students thinking ability, improve students’ mathematical quality of an important resource, but also test and sharpen the touchstone of teaching level. First, to change the way of thinking, touch the class bypass, highlighting the differences
