思维是人对客观事物的间接概括的反映过程。中学数学教学很重要的一个方面在于培养学生的思维能力。而思维能力的重要品质之一,便是学生思维的灵活性。 所谓思维的灵活性,是指根据题设中的具体条件,不拘泥于陈旧的模式和方案,不受思维定势的影响,及时转变或调整原有的思路和方法,变换思维的角度,寻找新的解决问题的途径和方法。 Thinking is the process of reflection of the indirect generalization of objective things. One of the important aspects of mathematics teaching in middle schools is to develop students’ thinking ability. One of the important qualities of thinking ability is the flexibility of student thinking. The so-called flexibility of thinking means that according to the specific conditions in the title setting, it is not rigidly adhered to the old model and plan, not influenced by the mindset, changing or adjusting the original ideas and methods in time, changing the perspective of thinking, looking for New ways and means to solve the problem.
