La enseñanza de las ciencias experimentales a partir del conocimiento pedagógico de contenido

Abstract

Abstract The main challenge before the teaching of experimental sciences is to stimulate students to enjoy physics and chemistry. This is the reason why it is so important to analyze the tasks of instructors before the challenges presented by upper secondary level students at the National Polytechnic Institute of Mexico. To carry out this analysis, it was necessary to first research the instructors’ pedagogic knowledge of the contents they teach, and then to identify the six characteristic fields of expertise in their work. This study was carried out based on the follow-up and description of the representation of contents, professional and pedagogic repertoires, in accordance with the experience of six professors, registered in the records and transcriptions of the classes. The level of expertise and depth of topics were essentials for all the teachers in giving their classes. In contrast, an important gap in the teaching of experimental sciences was teacher-student interaction.
