作为《数学课程标准(2011年版)》安排的四大课程内容之一,关于统计知识的学习内容有:收集、整理和描述数据,包括简单抽样、整理调查数据、绘制统计图表等。从数据中提取信息并进行简单的推断。主要与十大核心概念中对学生“数据分析观念”的培养和发展相对应。在现行人教版四上教材中,将实验版教材原分散在第一学段不同年级的条形统计图知识进行了重新梳理、整合。本文通过对该单元第一课时的实践研究,立足于让学生经历知识形成过程,从而发展数学学习能力的角度,谈一些思考和体会。
As one of the four courses scheduled for the “Mathematical Curriculum Standard (2011 Edition)”, the learning content on statistical knowledge includes collecting, organizing and describing data, including simple sampling, arranging survey data and drawing statistical charts. Extract information from the data and make simple inferences. Mainly with the ten core concepts of students “data analysis concept ” corresponding to the training and development. In the fourth edition of the current teaching textbook, the original version of the experimental textbooks scattered in the first semester of different grades of bar charts were reorganized and integrated knowledge. Through the practical study of the first lesson of this unit, this article based on let students experience the process of knowledge formation, thus developing mathematics learning ability point of view, to talk about some thinking and experience.
