The Persistence of Prior Concepts about Electric Potential, Current Intensity and Ohm’s Law in Students of Engineering

The Persistence of Prior Concepts about Electric Potential, Current Intensity and Ohm’s Law in Students of Engineering

The aim of this research was to evaluate and analyze second-year industrial-engineering and chemical-engineering students’ prior knowledge of conceptual aspects of circuit theory. Specifically, we have focused on the basic concepts of electric potential and current intensity and on the fundamental r...

Ideas previas teoría de circuitos estudiantes de Ingeniería. The aim of this research was to evaluate and analyze second-year industrial-engineering and chemical-engineering students’ prior knowledge of conceptual aspects of circuit theory. Specifically, we have focused on the basic concepts of electric potential and current intensity and on the fundamental relationship between these as expressed by Ohm’s Law. In order to find out what the students’ prior concepts were, we applied a survey containing nine questions dealing with the most basic concepts of circuit theory. Let us emphasize that there was little information available about the prior concepts of the population type (university students) investigated in this research. El objetivo del trabajo que se presenta es la evaluación y el análisis de los conocimientos previos sobre los contenidos conceptuales de Teoría de circuitos que tienen los alumnos de segundo curso de Ingeniería Industrial e Ingeniería Química, con la finalidad de detectar la persistencia de estos conocimientos desde niveles educativos anteriores. Concretamente, nos hemos centrado en los conceptos básicos de potencial eléctrico e intensidad de la corriente, así como la relación fundamental entre ellos, expresada a través de la ley de Ohm. Para detectar las ideas previas de los estudiantes se les ha propuesto un formulario que consta de nueve cuestiones todas ellas relacionadas con los conceptos más básicos de la Teoría de circuitos. Los resultados obtenidos nos confirman la hipótesis principal de la investigación: las ideas previas de los alumnos en el campo de la Teoría de circuitos persisten desde los niveles educativos anteriores hasta el universitario. Hay que destacar que el estudio se ha llevado a cabo en un tipo de población (los estudiantes universitarios), de los cuales no se tiene mucha información en lo que se refiere a sus ideas previas.
