A Preliminary Study of Development of Fuzzy Composite Score for Multiple Assessments (Article written in chinese)

Hao-Chang LO

Abstract

Multiple assessments have taken the place of single standardized test recently. Tools, forms, and standards are multiple in the process of assessments. How to integrate scores of multiple assessments into a composite score will be an important subject in educational research. The aim of this research was to propose an operating mechanism based on fuzzy theory to integrate scores of multiple assessments. The character of fuzzy theory was to process information vaguely, imprecisely, and uncertainly. The composite score was called “ fuzzy composite score, FCS” in this research. A simulated sample was used to test this fuzzy scoring frame. As the result shown, the operating mechanism agreed to the hypotheses and purpose of this research. It was convenient to integrate scores in different scales, too. Finally, some suggestions for future researches were proposed including how to design the professional software and build knowledge base of expert systems. It’ s believed that works based on this research will make FCS more close to the educational practice in the future.
