Abstract

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.

Highlights

Over the years, innovation and the appearance of new lines of research have found use incorporating new areas of knowledge as instruments of academic training
Bartlett’s sphericity test was applied before using the multivariate factor analysis technique in order to verify if the correlation matrix is an identity matrix, which means that the correlations between the variables are zeros
Given that Factor 1, displays a greater variance percentage than Factor 2, this indicates that the students of the Escuela Politécnica Nacional give the greatest importance to the teacher-student relationship, or, in other words, perform the assessment of the teacher depending on the quality of this

Summary

Introduction

Innovation and the appearance of new lines of research have found use incorporating new areas of knowledge as instruments of academic training. That is where the application of instruction psychology is proposed as a new teaching staff tool. This has served as a guideline for the appearance of new research that seeks to holistically understand the teaching process within the methodology and the best alternative to transmit knowledge in the classroom.
