概率与统计是新课程改革后初中数学的一个重要组成部分,了解初中生的学习现状对于学生的学习具有很重要的意义。本文通过调查发现初中生统计与概率的学习现状为:对于“统计与概率”的基本概念,学生掌握得比较好,但对于总体、样本和方差等概念掌握得较差;学生对于制作统计图表和概率的学习有一定的困难。因此,教学时要让学生积极参与到实践活动当中去,体验统计的思想方法,培养学生勇于探索的品质。
Probability and statistics are an important part of junior high school mathematics after the reform of the new curriculum. It is of great significance for students to learn about the learning status of junior high school students. This survey found that the status quo of statistics and probabilities of junior high school students is: for the basic concepts of “statistics and probability”, students have a better grasp, but they have poor grasp of concepts such as population, sample, and variance; students are responsible for making statistics. There are certain difficulties in learning about graphs and probabilities. Therefore, students should be actively involved in practical activities in teaching, experience the statistical methods of thinking, and cultivate the quality that students dare to explore.
