1 教材分析本章内容是在七年级(上)“可能性”知识的基础上展开的,学生已经接触了不确定事件,初步体会了不确定事件的特点及事件发生可能性的意义.在本章中,学生将在“猜测——实验并收集实验数据——分析实验结果”的活动过程中进一步了解不确定现象的特点,了解必然事件、不可能事件和不确定事件发生的可能性大小、事件发生的等可能性及游戏规则的公平性;通过具体情境体会概率的意义,体会概率是描述不确定现象的数学模型,并能对两类事件(古典概型、几何概型)发生的概率进行简单的计算,设计出符合要求的简单概率模型,让学生在猜测、实验、收集与
1 textbook analysis This chapter is based on the seventh grade (on) “Possibility ” knowledge based on the students have been exposed to the uncertain events, the initial experience of the characteristics of the uncertain events and the significance of the event possibility. In this chapter, students will learn more about the characteristics of uncertainty in the course of “Guessing - Experimenting and Collecting Experimental Data - Analyzing Experimental Results” to understand the possibility of occurrences, incidents and uncertain events Size, probability of occurrence and the fairness of the rules of the game. Through the realization of the probability of the specific situation, probability is the mathematical model describing the phenomenon of uncertainty, and the occurrence of two types of events (classical probability and geometric probability) The probability of simple calculations, designed to meet the requirements of the simple probability model, so that students in the guesswork, experiment, collection and
