A Study on the Application of Fuzzy Synthesis Assessment in the Development of Teacher Evaluation System on the Internet

[[abstract]]Teacher evaluation is crucial to assess the professionalism of teachers and the teaching efficacy. Teaching is a profession and whoever works in the field must go through a reasonable evaluation. Evaluation results can be obtained through either objective data, such as those gained from traditional written tests or based on objective criteria, or the obscure and subjective judgment from evaluators? feelings or observations. However, traditional teacher?s qualification tests or evaluation modes were focused on quantitative indexes, and the whole process didn?t pay much attention to the less concrete qualitative indexes, so that the fairness and objectiveness of the whole process was at issue. People often referred to it as an under-the-table operation. The traditional Weighted Scoring Method, though simple and easy to understand, had too many evaluators, which results in score inconsistency. Besides, oral tests or trial teaching tended to be the obscurity of qualitative and subjective was not suitable for or could not be used in establishing definite evaluation values and therefore could not reflect the real situation and seemed unreasonable. Therefore, this study introduced the fuzzy theory and used the fuzzy synthesis assessment to explore the teacher evaluation method that was different from the weighted average method and developed a fuzzy teacher evaluation system with the hope to make the evaluation more reasonable and thorough. This study tried to use the fuzzy Delphi technique to obtain the expert group decision and used it to weigh each evaluation factor. It also applied the fuzzy synthesis assessment to integrate the evaluation results and present the results in fuzzy distribution and fuzzy percentage assessment in order to establish a mode in evaluating the teaching efficacy. Furthermore, this study combined the developed teacher evaluation mode with Web technology and constructed an Internet teacher evaluation system so that the evaluators can evaluate on line. By using the fastness and correctness of computer scoring, the evaluated teachers could have immediate access to the evaluation results. This system features individuality, comprehensiveness, and no distance limitation. This study also conducted empirical application of the proposed evaluation mode and explored its advantages and disadvantages for education decision-makers? future reference
