在学习数学的过程中,各种数学方法的掌握与运用尤其重要。针对不同类型的题型选用正确的数学方法就能起到事半功倍的效果。在平时的学习与考试中,灵活地选用数学方法不仅可以有效地解决问题,更重要的是使学生建立起学好数学的自信心,从面提高学生学习的积极性、培养他们对数学的兴趣,让他们感受到数学世界的奇妙。一、排除法排除法:所谓排除法就是检验选择题中某些选项是否符合题设要求,将不符合的选项排除,从而得出正确答案的方法。
In the process of learning mathematics, the mastery and application of various mathematical methods are especially important. For different types of questions using the correct mathematical method can play a multiplier effect. In normal learning and examinations, the flexible use of mathematical methods can not only effectively solve the problem, but more importantly, enable students to build their confidence in math and improve their enthusiasm in learning and develop their interest in mathematics. They feel the marvelous world of mathematics. First, the exclusion method Exclusion method: The so-called exclusion method is to test the choice of some of the options in line with the requirements of the title, the exclusion of the option does not meet in order to draw the correct answer.
