Didactic-Mathematical Knowledge for the Teaching of Elementary Mathematics in future teachers of basic education: design, construction and validation of an evaluation instrument

Abstract

This paper presents the process of design, construction and validation of an instrument whose purpose is to evaluate partial aspects of didactic-mathematical knowledge for the teaching of elementary mathematics in future teachers of Basic Education. To this end, we have placed ourselves from the perspective of the Onto-semiotic Approach to Knowledge and Mathematical Instruction, since it provides analysis tools that allow us to provide evidence about the common knowledge of the content, the expanded knowledge of the content and the specialized knowledge of the content for the improvement of initial teacher training.
