Epistemic suitability of the unit of positive and negative numbers of the official seventh grade mathematics textbook of the Ministry of Education of Honduras

Abstract

The ontosemiotic approach is an integrative theoretical framework that provides the theoretical tools necessary for the study of didactic phenomena in the teaching-learning process of mathematics. This study presents the results of the use of the notion of didactic suitability and specifically of suitability in the epistemic facet. In this sense, strengths and weaknesses of a mathematics textbook were identified from the ontological and semiotic perspective. In addition, the necessary inputs are provided for the epistemic improvement of the textbook, its ontosemiotic configurations (primary objects) and an assessment of the contents presented by it.
