Impact of EDA on primary education

The purpose of this paper is to show how the spirit of EDA (Exploratory Data Analysis) may be used at the primary level, the focus being on exploration and stem-and-leaf displays. The paper has three major chapters, one about pupils in primary school, one that deals with student teachers for such pupils, and one about in-service education of teachers who have once been such student teachers. The chapter about pupils begins with a rather lengthy description of a lesson with a grade 3 class. I felt a more abbreviated description could not convey the atmosphere properly, and so I decided to include this fairly complete account of the lesson. The remaining chapters are less detailed and describe some of my experiences of spreading the very basic ideas of EDA to future and practicing elementary teachers. This work is of course necessary when one wishes to introduce EDA in schools.
