摘要:为了克服现有英语教材评估中的主观随意性;本文作者将可读性理论和模糊层次分析法引入到英语教材评估中;提出了一种新的英语教材评估模型。该模型利用可读性理论对教材的文本语言特征进行分析;采用德尔菲法(Delphi)和模糊层次分析法(FAHP)建立教材评估指标层次模型;并进行权重分配。该模型运用科学的定量手段刻画教材评估中的定性问题;使定性分析和定量分析等得到了良好的融合;从而提高了教材评估的客观性和准确性。本文在教材评估实例部分给出了基于该评估体系的两套英语教材的试评结果。
To overcome the shortcomings of the traditional empirical evaluation of English textbook,the authors put forward an alternative model of evaluation system based on readability theory and fuzzy analytic hierarchy process(FAHP) in this paper.Readability theory is applied to analyze the language features of textbook.Delphi method and FAHP approach are employed to determine evaluation criteria at three levels and weight each criterion.Scientific mathematics method is used to overcome the subjectivity in the process of textbook evaluation,and add qualitative analysis and objectivity.A sample test is conducted under the evaluation system.
