论文部分内容阅读
无论是在高二新授课时还是高三一轮复习时,我都负责编写了概率统计内容的学案,比较了旧课标和新课标高考题中这部分的分值和题型,并且认真研读了四川高考对概率统计部分内容的难度要求。通过比较,发现实行新课标后,概率统计这部分的高考题量没有加大,但是内容有新的突破,综合性更强。体现了“稳中求变,重视基础,标新立异,符合实际”的数学改革思想。一、新教材与旧教材中概率内容区别旧教材在统计方面只介绍了抽样方法、用样本去估计总体以及正态分布,在概率方面介绍了基本事件的概率、分布列、期望,而新教材删除了正态分布这部分内容,在旧教材的基础上新增加
No matter when I was a sophomore or a senior one, I was responsible for compiling the case of probability and statistics content, comparing the scores and questions of this part of the old curriculum standard and the new curriculum standard college entrance exam, and carefully studied Sichuan college entrance examination of the probability of statistical content of the part of the difficulty requirements. Through the comparison, it is found that after the implementation of the new curriculum standard, there is no increase in the number of entrance examinations in this part of probability and statistics, but there is a new breakthrough in content and more comprehensiveness. Embodies the “change in the steady, pay attention to the foundation, unconventional, in line with the actual” mathematical reform. First, the difference between the new textbook and the old textbook Probability content The old textbook introduces only the sampling method in the statistics, with the sample to estimate the overall and normal distribution, the probability of basic events introduced probability, distribution columns, expectations, and the new textbook Removed the normal distribution of this part of the content, based on the old teaching materials added
