Guidelines to analyze the epistemic and cognitive suitability of statistical tables lessons in textbooks

Abstract

Since statistical tables are widely used to represent and analyze information in the study of different subjects, their teaching is considered in the curricular guidelines of several countries. In this article we present a guide to analyze the epistemic and cognitive suitability of lessons related to statistical tables in textbooks. The development of the guide is based on the theory of didactic suitability of the onto-semiotic approach to mathematical knowledge and instruction, which provides theoretical elements that allow to assess the instructional process proposed in the textbook. Through a content analysis, we identify indicators of epistemic and cognitive suitability in previous research, as well as in curricular guidelines, from which didactic-mathematical knowledge about statistical tables in primary and secondary education is selected and categorized. The guide focuses on facets that consider specific subcomponents for the mathematical content under study. Thus, the guide can support teachers in the analysis and evaluation of textbook lessons and in the design and implementation of the instruction process on statistical tables, as well as for teacher training as a resource to promote reflection.
