相比于单一的教学模式,学生更容易在生活情境中学习数学。数学源于生活,生活中的许多事情都与数学课上的“知识点”有着千丝万缕的联系,它们貌不相似,神却相通。《独立事件积的概率》一课是上海二期课改高中数学教材三年级第二学期的教学内容。独立事件积的概率与之前学习的古典概率和几何概率(等可能性事件)、互斥事件和的概率是三类典型的概率模型,将复杂问题分解为这三种基本形式,是处理概率问题的基本方法。因此,本节课内容的学习,既是对所学知识的深化与拓展,又是提高学生解决现实问题能力的一种途径,更是加强学生应用意识 Compared to a single teaching model, students are more likely to learn math in life situations. Mathematica comes from life, many things in life are inextricably linked with “knowledge points” in math class. The probability of independent event plot is a teaching content of the second semester of the third grade of math textbooks for high school in Shanghai. The probability of independent event product and the classical probability and geometric probability (equal possibility event) and the probability of mutual exclusion event are the three typical probability models, the complex problem is decomposed into these three basic forms, which is to deal with the probability problem The basic method. Therefore, the contents of this lesson to learn, not only deepen and expand the knowledge learned, but also to improve students’ ability to solve practical problems is a way, but also to enhance student awareness of the application
