教材分析“树状图”是初一《数学》下册中继“这游戏公平吗?和”停留在黑砖上的概率“之后的一个学习内容。在现代社会里,人们面临着许多的机会和选择,常常需要在不确定情境中作合理的决策。概率正是通过对不确定现象和事情发生可能性的刻画,来为人们更好地制定决策提供依据和建议。这部分内容又是义务教育阶段唯一培养学生从不确定(或统计)的角度来观察世界的数学内容,让学生了解可能性是普遍的,有助于他们理解社会、适应生活。
The analysis of the textbook “Tree Map” is a learning content after the “Mathematics” book relay “is the game fair? And the probability of staying on the black brick”. In modern society, people face many opportunities And choices often require reasonable decisions in uncertain situations.Probability is to provide a basis and advice for people to make better decisions through the characterization of uncertain phenomena and the possibility of events.This part is also an obligation The only stage of education is to train students to observe the mathematical content of the world from the perspective of uncertainty (or statistics), so that students understand that the possibilities are universal and help them understand society and adapt to life.
