转化和化归思想在高中数学中非常常见,这一经典的数学思想在很多实际问题的解答中能够发挥的效用也十分明显。在平时的课堂教学中,教师要加强对这一数学思想方法的渗透,不仅要让学生更为熟悉化归思想,也要让大家具备灵活应用这一思想方法解决实际问题的技能。这样才能够体现这一思想方法的教学效用,才能够丰富学生的解题技巧,提升学生的综合数学素养。一、正与反的相互转化化归思想之所以在高中数学中的应用十分普遍,很重
The idea of conversion and return to normalcy is very common in high school mathematics, and the utility of this classic mathematical thought in many practical problems is also evident. In normal classroom teaching, teachers should strengthen their infiltration of this mathematical thinking method, not only to make students more familiar with the idea of return, but also let everyone have the flexibility to apply this method of thinking to solve practical problems skills. Only in this way can we reflect the teaching effectiveness of this method of thinking so as to enrich students ’problem-solving skills and enhance students’ comprehensive maths accomplishment. First, the positive and negative mutual conversion The reason why the thought in high school mathematics is very common, heavy
