Abstract (English): We present the results of research conducted on understanding about the concept of electric field, electric field lines, the direction and intensity of electric field and the relationship between it and the electric charge, with students of Chemical Engineering. We shown a teaching proposal based on the application of Toulmin's argumentative model in order to improve understanding of these concepts in students. We pretend to achieve the goal of proper understanding, through the construction of argumentative schemes under specific categories of analysis. Also, we discuss the advantages of applying this reasoning in an experimental student group, who were observed with a greater understanding of the concepts, and a slight increase in the average responses of the post-test compared with the results of control group.

Abstract (Spanish): Se presentan los resultados obtenidos de una investigación realizada sobre la comprensión del concepto de campo eléctrico, las líneas de campo eléctrico, la dirección e intensidad de campo eléctrico, así como la relación que existe entre éste y la carga eléctrica, que tienen los estudiantes de Ingeniería Química. Se presenta una propuesta didáctica basada en la aplicación del modelo argumentativo de Toulmin para mejorar la comprensión de estos conceptos en los estudiantes, en donde a través de la construcción de esquemas argumentales bajo categorías específicas de análisis se pretende lograr el objetivo de comprensión adecuada. Se presentan las ventajas de la aplicación de esta argumentación en un grupo experimental donde se observó una mayor comprensión de los conceptos en los estudiantes, así como un ligero aumento en la media de las respuestas dadas del post-test comparada con los resultados del grupo de control.
