教育心理学告诉我们:儿童认识事物可以从整体开始,通过局部之间关系的具体分析,进一步加强对整体的认识。这比从局部——局部——整体效果要好得多。基于上述认识,我对“小数乘法”例1—例6作了重新设计,采用“提前亮相”方法,即小数乘法第一、二堂课就教给学生计算法则,让学生抓住基本原理,以一般带特殊,从而取得举一反三,触类旁通的效果。教学内容:六年制第九册小数乘法计算法则。教学要求:1.使学生掌握小数乘法计算法则,并能运用法则确定积的小数位数,点上小数点; 2.培养学生观察、比较、抽象、概括的逻辑思维能力;
Educational psychology tells us: children's understanding of things can be from the beginning, through the specific analysis of the relationship between the local, to further enhance the overall understanding. This is far better than a partial-local-overall effect. Based on the above understanding, I have “recklessly multiply” Example 1- Example 6 has been redesigned, using the “early appearance” method, that is, fractional multiplication first, two classes teach students to calculate the law, so that students grasp the basic principles to Generally with special, so as to obtain the best of the best, bypassing the effect of analogy. Teaching Content: The Law of the Fractional Multiplication of Ninth Book of Six Years. Teaching requirements: 1. To enable students to master the rules of fractional multiplication, and can use the rules to determine the decimal places, the decimal point; 2. Students students to observe, compare, abstract, generalized logical thinking ability;
