Evaluation of the presentation skills of the pre-service teachers via fuzzy logic

Abstract

The main purpose of this study is the presentation skills evaluation of pre-service teachers via fuzzy logic. There are two different groups in this study. The first one consists of 14 instructors serving in the Computer Education and Instructional Technology (CEIT) Department of Firat University (FU). This group has supplied expert view in ranking the importance of the matters in the Presentation Evaluation Scale (PES) and in forming the rule base that sets ground for the operation of fuzzy logic mechanism. The second group consists of 41 juniors having the Operating Systems and Applications Course in the CEIT Department of FU. The students in this group make a presentation associated with the units of this course, PES are applied on them and the study is conducted by the data obtained from this scale. Frequencies and percentages and Wilcoxon test is used to analyze the data sets. It is found that there is a significant difference between the PES obtained student scores and those scores that passes through fuzzy logic mechanism. The scores of some students have decreased, those of some have increased while there is no significant change in some of them.
