A Classroom Experience: Vector Concept.

Abstract

According to several studies, working with vectors is a problem for students from different educational levels. In this document we propose a Planeacion Didáctica Argumentada (PDA) to address the vector concept at lower secondary school level, emphasizing its features (magnitude, direction and sense) such that, it facilitates the formalization of the mentioned concept in a mathematical context. After implementing the PDA, we evidence that with the right instruction, students can develop skills to work with vectors. After analyzing the results, is possible to establish some aspects that must be considered while teaching vectors, for example: the aspects of the teacher, students, curriculums and the previous physics and math necessary contents.
