| 摘 要： | 动态评估近年来成为教育测量领域的热点。在动态评估的定量测量研究中，传统心理测量模式在评估前提、评估过程及预测学习者潜能方面存在局限，阻碍了动态评估在外语教学实践中的应用。基于马尔科夫链构建的动态评估模型以学习者基础的差异性为前提，在评估对象的个体性、评估过程的动态性与评估结果的预测性方面独具优 势。本文以大学英语词汇教学为例，阐述模型在外语教学动态评估中的应用，为教学实践中动态评估的定量测量研究 提供了科学的评估工具。

| Abstract: | Dynamic assessment is currently a research hotspot in the field of education measurement. However, in the study of quantitative assessment in this field, there are remarkable limitations in traditional psychological assessment mode, which hinders the application of dynamic assessment in ESL teaching practice. This paper proposes a dynamic assessment model (LEA Model, short for Learning Efficiency Assessment Model) constructed on Markov chain, which takes the students learning differences as the prerequisite, and shows distinct advantages in the aspects of individuality of assessment subject, dynamics of experiment, the application of LEA model in dynamic assessment is verified, thus introducing this model into dynamic assessment process and prediction of students learning potential. Based on a college English vocabulary classroom teaching assessment provides a scientific quantitative assessment tool for teaching practice. |
