Resources used by of the telebachillerato teacher to teach algebra: notable products

Abstract

In this document we propose as an object to describe how the Telebachillerato teacher uses the resources with which he has available to teach remarkable products. We return to the discussion on the concept of resource and its relation to teaching practice in mathematics. This paper reports a tele-teacher, as a case study in depth, focusing on the teaching of notable products. The teacher was observed (videorecording) in two sessions of classes with the purpose of, later, to generate a reflection on the use that it gives to the resources in mathematics and its impact in the learning. The results show that it uses the textbook and slides previously selected and studied. The teacher's interaction with the resources available reflects an interest in generating a mathematical learning, however there are gaps between the teacher's practice and the resources available in mathematics, which makes it difficult to understand what are remarkable products.
