基于D-S证据理论的初级口语课堂教学效果量化评估研究

On Quantitative Evaluation of the Teaching Effectiveness in Elementary Oral Chinese Classes Based on D-S Evidence Theory

在语言教学领域,任务型语言教学作为一种注重学生主动参与的教学法,在初级汉语口语教学中的应用效果评估尤为关键。本文旨在构建一个综合性的评估指标体系并提出一种改进的D-S证据理论模型,用以对TBLT在初级口语课堂中的应用效果进行量化分级评估。通过案例研究,验证了该模型的有效性,实现了对教学效果的全面量化和分级评估。该模型不仅细致地评估了课堂教学的实施情况,还揭示了教学实践中的优势与不足,为进一步改进教学实践提供了实证基础和实践指导。

It is of particular importance in the field of language teaching,where task-based language teaching(TBLT)emphasizes active student participation and requires effective evaluation in elementary Chinese oral classes.Therefore,this paper aims to establish a comprehensive evaluation index system and proposes an improved D-S evidence theory model to quantitatively assess the effectiveness of TBLT in elementary oral Chinese classes.Through case studies,the model's effectiveness,achieving comprehensive quantitative and graded evaluation of teaching effectiveness had been validated.This model not only meticulously evaluates the implementation of classroom teaching,but also reveals the strengths and weaknesses in teaching practices,providing empirical evidence and practical guidance for further improvement.
