Evidencias de Validez del Cuestionario Portilho/Banas Estilos de Enseñanza

Abstract

The use of instruments with evidence of validity in education research brings advances to the production of knowledge. This article reports the stages of a survey of teaching style and the evidence for its validity. One thousand teachers participated in a study of different levels of education. An exploratory factor analysis indicated a structure of four factors in which 55 items had a factorial load greater than .30. The correlation steps made it possible to identify how the four factors are related to each other. As a final result, the questionnaire was composed of 40 items, distributed into groups of 10 items organized by teaching style. Evidence of factorial validity and internal consistency of the items that make up the instrument was seen. Analysis of variance indicated that the scale is sensitive to individual differences in the comparison among the four different teaching styles and the gender and teaching level variables.
