This work validates a teaching evaluation instrument applied to professors in engineering, sciences and higher technological level programs of the Escuela Politécnica Nacional, using the method of Factor Analysis with extraction of principal components. The database used for the research was previously examined and refined due to inconsistency, eg. outliers, out of range values, etc. The result of the method described above was a reduced survey of 15 items, which was obtained from an original study of 33 items. This new questionnaire clearly identifies the four main dimensions or aspects required: teaching development and planning, teacher-student relationship, evaluation, and a global assessment question. The reduction of the evaluation scale will allow to improve the process of integral teaching performance evaluation of the faculty at Escuela Politécnica Nacional, and this method could serve as a benchmark for the teaching evaluation process of other universities that belong to the higher education system of Ecuador.
Este trabajo valida un instrumento de evaluación docente aplicado a profesores de las carreras de ingeniería, ciencias y de nivel tecnológico superior de la Escuela Politécnica Nacional, utilizando el método de Análisis Factorial con extracción de componentes principales. La base de datos utilizada en la investigación fue examinada previamente y refinada por inconsistencia - por ejemplo, valores atípicos, valores fuera de rango, etc. El resultado del método descrito anteriormente fue una encuesta reducida de 15 ítems, que se obtuvo de un estudio original de 33 ítems. Este nuevo cuestionario identifica claramente las cuatro dimensiones o aspectos: planificación y desarrollo de la docencia; relación profesor-alumno; evaluación; y una pregunta de valoración global. La reducción de la escala de evaluación permitirá mejorar el proceso de la evaluación integral del desempeño docente del personal de la Escuela Politécnica Nacional, y este método podría servir de referencia para el proceso de evaluación de la enseñanza de otras universidades que pertenecen al sistema de educación superior del Ecuador.
