Statistical Graphs Semiotic Complexity, Purpose and Contexts in Costa Rica Primary Education Textbooks
Résumé
The aim of this research was analyzing the way in which statistical graphs which are introduced in the new curricular guidelines for Costa Rica primary education are introduced in the textbooks, and compare the results with previous research in other countries. We analyze the distribution of the graph complexity, purpose and context in 167 activities related to statistical graphs selected from the two most widely used textbooks series. Results suggest a non-uniform distribution in both series and suggest ways to enhance the activities proposed in the textbooks.
