Problemi e osservazioni sul questionario utilizzato per la valutazione della didattica da parte degli studenti frequentanti

Student evaluations of teaching activity are compulsory in Italian universities and the National Committee for University System Evaluation (Comitato Nazionale di Valutazione del Sistema Universitario, CNVSU) proposed a course-evaluation questionnaire with items based on the four-point Likert scale and a traditional item-by-item analysis. This paper illustrates the main issues concerning the student evaluation of teaching, the survey and sample designs adopted to carry out the evaluation of the teaching activity, the wording of the proposed items, the timing of surveys because it could affect the results, and the advantages or disadvantages of the four-point Likert scale.
