教师的职责是在传授知识的同时,还要重视培养学生的思维能力.特别是数学教学,既要开发学生智力,又要发展学生能力,更应重视培养学生多方面的思维.一题多变可以培养学生思维的灵活性,从变换的角度去联想.可以更好掌握全面知识,将知识深化,达到举一反三,提高学生分析问题、解决问题和“发散”思维的能力.例如高中课本代数第一册第二十八页例题2:已知函数 f(x)是奇函数(条件1)而
The teacher's duty is to impart knowledge while at the same time paying great attention to cultivating students 'thinking ability.Many mathematics teaching, especially, should not only develop students' intelligence, but also develop students 'abilities, and should pay more attention to cultivating students' various thinking. Can cultivate students' flexibility in thinking and think from a transformation point of view, can better grasp the comprehensive knowledge, deepen the knowledge, and achieve the ability to analyze, solve problems and “divergent ” thinking, such as high school textbook algebra Example 1: Problem 2: It is known that the function f (x) is an odd function (condition 1) and
