实验,就是通过实践活动来探究事物内部联系及其规律,检验意识的可行性、思维正确性程度的一种行为。作为自然科学学科的数学,实验是一种必不可少的教学手段。学生的认识规律总是“实践一认识一再实践一再认识”,即从具体形象思维逐步向抽象逻辑思维推进的。数学教学要使学生感受到数学知识发生、发展的过程,提高学习质量,实验是不可缺 Experiment, is through practice activities to explore the internal relations of things and its laws, test the feasibility of awareness, the correctness of the thinking of a behavior. As a natural science math, experiment is an indispensable teaching method. Students' understanding of the law is always “practice a common understanding of repeatedly recognized practice”, that is, from the specific image of thinking gradually to the abstract logical thinking. Mathematics teaching makes students feel the process of mathematical knowledge, development, improve the quality of learning, the experiment is indispensable
