Higher education teaching and exploitation of student evaluations through the use of control charts: revisited and expanded

Abstract

Student evaluations on the teaching efficiency of faculty members are significant in Higher Education because they allow decisions makers to identify potential inefficient faculty members and by making appropriate decisions, to improve the quality of the teaching process of their Institution. In this paper, we revisit the methodology framework of the previous paper of Sivena and Nikolaidis in order to expand it in various ways. More specifically, we examine in detail and evaluate through simulation, several popular types of $\overline{X}$ and $\tilde{X}$ control charts, identifying the most suitable among them, using various statistical properties of control charts as optimization criteria. Additionally, we present two more tools that will allow Higher Education Institutions if exploited in real life, to find differences in the teaching performance between evaluated faculty members, either the latter are compared in one or more pairs. All in all, we provide Higher Education decision-makers with easy-to-use and reliable tools for monitoring the teaching process of their Institutions.
