“数学是思维的体操,数学对于思维的训练有着特别的重要性。”在课程改革的今天,在数学教学过程中,通过利用一切有用条件进行对比、联想,采取一题多问、一题多变、一题多解的形式教学,对培养学生思维的广阔性、深刻性、探索性、灵活性、独创性无疑是一条有效的途径。同时,也是让学生脱离题海战术、向40分钟要效率的方法之一。通过这种训练,有助于学生更深刻地理解所学知识,促进和增强学生思维的深刻性,充分训练学生思维的应变力、想象力及创造力,训练学生对数学知识的理解能力、应用能力和想象能力,达到“减负”和“增效”的目的,真正把“以学生为主体,训练为主线,能力为主攻”的原则贯穿于教育教学中,把学生的能力培养落到实处。 “Mathematics is the gymnastics of thinking, and mathematics is of particular importance for the training of thinking.” In today’s curriculum reform, in the process of mathematics teaching, by using all the useful conditions for comparison and association, Talking about change, a problem of multiple forms of teaching, to develop students thinking broadness, profoundness, exploration, flexibility, originality is undoubtedly an effective way. At the same time, it is also a way for students to break away from the sea tactics and get 40 minutes to be efficient. Through such training, it helps students to understand more deeply what they have learned, to promote and enhance the profoundness of their thinking, to fully train students ’resilience, imagination and creativity in thinking, and to train students’ understanding of mathematical knowledge. Ability and imagination ability to achieve the goal of “reducing the burden” and “boosting efficiency”. The principle of “taking the student as the main body, the training as the main line and the ability as the mainstay” should be put through education and teaching, Ability to carry out.
