54 Study on Teaching Evaluation Based on System Engineering Theory

This paper studies the student rating mechanism and teaching evaluation problem which the student ratings results are not directly comparable based on systems engineering theory and approach. Our study shows that this problem is sources of systematic error-“error between groups” and “error within group”. And then, with the help of the computer technology model(repeated iteration model) and more scientific mathematical access(the relative mean method), the technology solutions are proposed for optimizing the management of teaching evaluation.
