摘要
概率统计是我国中小学数学课程内容中一个重要的组成部分.理解样本概念和抽样方法是基本的统计素养,深入研究中学生对样本概念的理解对有效地开展中学统计教学是非常必要的.在统计教学方面:(1)可以用样例的方式介绍样本概念;(2)强调样本对总体的了解或检验应成为样本概念教学的一个组成部分;(3)教师应重视通过实践活动来改变学生存在的一些错误的或不合理的认识.
Statistics and probability would be an integral part of our national school mathematics curriculum in near future. An understanding of sample and sampling methods were fundamental to statistics literacy and studied on students’ understanding of sampling was really necessary for improving the statistics teaching and learning. In this research, 723 students without any formal statistics training selected from grades 7, 8, 10 and 11 were surveyed. It was found that after reading a sample example of sample, most of all the grades’ students were able to have a better understanding of the concept sample.
