BRIEF TEXT


… [1-9] Despite all the differences between opinions on the application of teacher evaluation by students, this evaluation is increasingly used by students as a reliable and credible source in higher education institutions for making various decisions [8, 10-15]. Students` insufficient knowledge to judge the quality of teaching, the effect of personal judgments, time for evaluation of the performance, and the method of evaluation are the main shortcomings of this method of evaluation [13, 14].

Some persons oppose the teacher evaluation by students, but others assess it as a valuable source of feedback to teachers to improve the quality of teaching [16-23]. At Hamadan University of Medical Sciences, more than 65% of professors did not accept the results of this evaluation [15]. … [24]

The aim of this study was to evaluate consistency of evaluation of professors by students, according to two different protocols.

This is an interventional study.

All students in Asadabad Faculty of Medical Sciences (Iran) who were studying in three fields including nursing in undergraduate level, public health in undergraduate level, and medical emergency in the associate level were studied in the academic year of 2014-2015.

Samples were selected based on census method. Totally 26 professors who were teaching 53 courses were evaluated by 174 students in two different semesters based on two protocols.

At the end of each consecutive semester, teacher evaluation by students, in the first round was carried out a week before the exam, and in paper-based form using a standard evaluation form in which the profile of the relevant course and teacher were specified (Protocol A). At the next stage, the evaluation was conducted as computer-based form on the conventional method in the Asadabad Faculty of Medical Sciences and through Sama System (Protocol B). In each semester, 4 courses were randomly selected and the questionnaire relevant to instructors` evaluation by students of that specific course was extracted based on executive protocols. The questionnaire used for this study was a tool defined by Hamedan University of Medical Sciences including 18 multiple choice questions as excellent, good, average, and poor which was evaluating the university instructors` performance from the students` point of view at the end of each semester. After collecting data and enter it in Excel 2013 software, it was monitored and then the information was transferred to SPSS 20 software. Descriptive statistics, including tables, indexes and charts were used to describe the characteristics of the studied population, and inferential statistics such as Independent T-test, Paired T-test, and Pearson`s Correlation Coefficient or their nonparametric forms were used for data analysis.

The results of evaluation of 53 courses including 21(40%) of courses in the second semester of 2014 and 32 (60%) of courses in the first semester of 2015 were investigated. The mean scores were different in two executive protocols in the way that the mean score in the protocol A was less than the mean scores in the protocol B. Also, the standard deviation of scores in protocol A was more than the standard deviation of scores in protocol B. The mean score of two executive protocols was statistically different in general and separately for each question (table 1). Also, the correlation between the total score of all statements was significant. The mean score received by students in nursing, emergency medicine and health in protocol A were 68.47 ± 18.38, 81.18 ± 10.89 and 65.40 ± 17.68 respectively. And there were 91.93 ± 4.58, 90.07 ± 5.90 and 96.49 ± 2.66 in the protocol B respectively. There was no significant difference between the protocols. Also, the mean of change in the score of evaluation by the students based on the two executive protocols in the two consecutive semesters of 2014 and 2015 were 23.11 ±12.52 and 23.54 ± 16.58 respectively. And it did not show a significant difference. The other studied parameters were the possibility of changing the student evaluation score in the two protocols based on the number of spent semesters. The results showed no significant differences in changes in teacher evaluation score based on this factor. Also, the levels of change in the score of teacher evaluation by students in general and specialized courses in the second semester of 2014 and in the first semester of 2015 were 34.02 ± 15.17 and 21.65 ± 13.28 respectively. And it showed statistically significant difference.

Teacher evaluation by students is a valuable source for giving feedback to professors in order to improve the quality of teaching [20]. Because of the effect of personality traits and characteristics on people`s understanding and judgment, this kind of evaluation is not appropriate [21, 25]. The distribution of evaluation scores was more in protocol A compared to protocol B indicating greater difference between teachers` evaluation scores based on protocol A. There are no similar paper-based and computer-based studies on the impact of the implementation of teacher evaluation by students. The majority of university instructors and students assess the time of university instructors` evaluation as an important factor in the evaluating score [19]. The time of evaluation is one of effective factors in the university instructors` evaluation by students from the faculty members` point of view [26]. About 61% of students considered tough test as an effective factor in university instructors` evaluation [18]. Based on this study, the best time for evaluation from the perspective of significant number of university instructors and students is at the end of the semester and before the exams. And based on the views of some of the instructors, the best time for evaluation is during the semester as a continuous method, which is consistent with the present results.

Before the exam, instructors` evaluation by students should be carried out electronically.

One of the limitations of this study was inability of researchers to isolate the effects of the implementation of the study in paper-based form and electronic system based in collecting data.

Evaluation of instructors by students in paper-based method and before exam scoring by instructors is more appropriate and leads to a higher differentiation among university instructors compared to instructors' evaluation by students in computer-based method and during exam scoring by the university instructors.

Education Deputy of Asadabad Education Faculty of Medical Sciences is appreciated.

There was no case.

All questionnaires were name-less and without any other characteristics of the students.

This project was funded by Medical Education Development Center for Education Deputy and Research and Technology Deputy of Hamadan University of Medical Sciences.
