数学是逻辑性很强的一门学科.发展学生的思维能力,尤其是逻辑思维能力,这是小学数学教学大纲提出的目的和任务之一.因此,在教学中要把培养学生思维能力摆在重要的位置上,通过比较、分析、综合、抽象、概括、判断、推理等方法,逐步形成.1、引导观察、比较、判断,训练直觉思维.直觉思维,它是逻辑的基础,它是从整体上来研究并直接接触问题的实质的一种思维方法,在推理过程中有紧缩性和选择性等特点.由于儿童生理特点所决定,小学生的逻辑思维是在直觉思维基础上形成的.所以教学中,要善于引导学生观察、比较,对数学知识的正、误作出判断,学生的直觉思维才能不断提高,相应地学生的逻辑思维也能逐渐提高.如在四则混合运算教学中,引导学生对
Mathematics is a very logical discipline.Developing students 'thinking ability, especially logical thinking ability, is one of the goals and tasks proposed by elementary mathematics syllabus.Therefore, in teaching, we should cultivate students' thinking ability On the important position, through the method of comparison, analysis, synthesis, abstraction, generalization, judgment, reasoning and so on, it gradually forms.1, Guidance observation, comparison, judgment, training Intuitive thinking Intuitive thinking, which is the basis of logic, As a whole, there is a kind of thinking method of studying and directly contacting the essence of the problem, which has the characteristics of compactness and selectivity in the process of reasoning.Due to the children's physiological characteristics, the logical thinking of the pupils is formed on the basis of intuition thinking.Therefore teaching , We should be good at guiding students to observe, compare, make judgments on the positive and false mathematical knowledge, students 'intuition thinking can continue to improve, correspondingly the students' logical thinking can also be gradually improved .As in the four mixed computing teaching, to guide students to
