Qué significado atribuyen a la media aritmética profesores de matemática en ejercicio?

Abstract

The objective of this work is to study if professors in practice can identify the partial meaning of the arithmetic average mathematical object that allows solving a certain problem. For this, the answers of 95 teachers were analyzed to a task that consisted in relating the different meanings of this mathematical object with a list of proposed problems. It is concluded that the majority of teachers fail to correctly relate the meaning of the mean with the statement of the corresponding problem and, those who manage to relate, justify this relationship incorrectly.
