Conexiones Matemáticas utilizadas por profesores mexicanos de nivel medio superior al resolver tareas sobre la pendiente

Abstract

The aim of this research was to identify the mathematical connections made by a group of Mexican high school teachers when solving tasks that involve the concept of slope. A mathematical connection is understood as a true relationship between two or more ideas, concepts, definitions, theorems, procedures, representations, and meanings among them, with those of other disciplines or of real life. A task-based interview was used to collect data, and thematic analysis were used to analyze the data. The results indicated that teachers made six types of mathematical connections: different representations, procedural, meaning, feature, part-whole and implication
