RESEARCH ON UNCLEAR COMPREHENSIVE EVALUATION OF HIGH-STAKES WRITING TEST

Abstract

Reliability of the scoring link is highly correlated with an overall reliability of a test. High reliability of the score can improve reliability and validity of a test. Since writing assessment is highly subjective and imprecise, ensuring the consistent and reliable assessment standard has been a difficult and urgent problem of high-stakes language tests. Accomplishing the analysis of current writing assessment methods and the existing problems, the researcher proposes new ideas for writing assessment methods and states that the unclear comprehensive evaluation should be employed to quantify the writing assessment standards. The paper also constructs a mathematical model for writing quality evaluation and analyzes the advantages and disadvantages of this model so as to provide a more scientific, objective, accurate and comprehensive assessment method.
