Comparing Two Stages of Teacher Evaluation from Students, Opinion

Having student's opinions is an appropriate method for teacher's educational development. Accomplishment of evaluation and acquired scores always have been challenged, so the aim of the present study was to compare two stages of teacher evaluation from student's opinion. In this cross-sectional study, 110 students during the second term of educational year 2010-2011 to 2011-2012 participated. Evaluation was done by form No.3 of Educational Development Center (EDC) which contained 13 questions. First evaluation was done by EDC. The second evaluation was done in the last session by the teacher. Data were analyzed by paired t-test and Wilcoxon with SPSS version 15. Results of paired t-test showed that there was no significant difference between two evaluations (p=0.46). Wilcoxon test was used to compare each question of questionnaire for lack of normal distribution and results did not show significant differences for all the 13 questions. The present study demonstrated no differences according to the time of evaluation. Besides, no differences were seen between evaluations done by the teacher and another evaluator. If results are going to be used for any decision making about the teacher, it is recommended to perform evaluation in several terms, so, the teachers can be informed about their ranking in comparison with other colleagues.
