Una secuencia didáctica para abordar el concepto de calor en la enseñanza de estudiantes preuniversitarios

Abstract

In this paper a teaching sequence to describe and teach the concept of "heat" is presented and analyzed. The study is based on the theory of conceptual profile given by Mortimer, applied to a pre-university course from a high school, in Brazil. The comprehension of concept such as heat, discussed in this work is many times crucial for the success of student during their first courses in the university. A didactic sequence is developed and applied to relate the material world of students with scientific concepts such as heat. The proposal includes the use of commercial videos, academic software and a virtual experiment popular on the Internet. The results show that the proposed didactic sequence is appropriate for the better comprehension of the concept of heat by students.
