基于三角模糊数的大学英语课堂教学质量评价研究

Evaluation on Teaching Quality of College English based on Triangular Fuzzy Numbers

英语课堂教学质量评价是高等院校英语教学质量管理的重要环节,对提高教师教学水平和改善教学效果起到监督和促进作用。已有英语课程教学评价体系相对陈旧、缺乏英语学科特色,部分指标的语言表述超出学生的理解能力,针对这些问题,以学生为评价主体建立适合大学英语教学的评价指标体系。由于评价体系多为个人定性指标,评估值具有模糊性,因此提出一种基于语言短语和三角模糊数的大学英语课堂教学质量评价方法,并对某高校四名英语教师进行了算例分析。算法步骤清晰,可以运用计算机输入直接实现,便于在英语教学评价中进行推广。

As an important part of the quality management of English teaching in colleges and universities, the evaluation of teaching quality can supervise and improve teachers’ classroom teaching quality. The existing evaluation system of English class is relatively outdated. Most indicators lack in the characteristics of English subject, which can be applied to any course;some indicators are too difficult for the students to understand. In view of these problems, this paper establishes an evaluation index system suitable for college English teaching with students as the evaluation subject. Since evaluation involves many qualitative indicators, which makes the evaluation value fuzzy, this paper proposes a new method of evaluating college English classroom teaching quality based on linguistic phrases and triangular fuzzy numbers. Finally, the algorithm case is analyzed by an example. The procedure of the algorithm is clear and can be realized directly through computer input, which is convenient to apply in teaching evaluation.
