EVALUATION OF TEACHING STAFF TO INCREASE THE QUALITY OF ENGINEERING EDUCATION THROUGH MANY FACET RASCH MEASUREMENT MODEL

Abstract

In this study, we have analyzed the performance of teaching staff in a college of engineering of a university. Our analysis is based on a survey of students and involves the many-facet Rasch model. The study group consisted of a sum of 683 students enrolled at the depai tuient of civil engineering at a university in Turkey in 2017-2018 academic year. The department of civil engineering included 62 courses. 25 of these courses were used for evaluating the general performance of teaching staff and 6 of them were used in the evaluation carried out through Rasch measurement model. SPSS program was used in the general evaluation. For the analyses carried out using Rasch measurement model, 20 raters (students) evaluated the instructional process of 6 teaching staff. A questionnaire consisting of 16 items was used as the evaluation criteria. As the findings on the general evaluation of teaching staff indicate, the teaching staff performed at usually level for the frequency of the tasks they are expected to fulfil according to the evaluations of students. As for the evaluations carried out through Rasch model, it was observed that teaching staff 4 exhibited the highest performance while teaching staff 3 performed the lowest one. When the raters were listed from the most lenient to the most stringent one, E2 and E20 were the most lenient ones whereas E14 was the most stringent. It was also observed that among the items used as criteria in the process of evaluation by the raters, aim and scope was the hardest to realize on the side of the teaching staff while fair evaluation, neutral towards students and teaching were comparatively easier to fulfil.
