实时双向教学评价体系研究

Research on the Real-time Two-Way Teaching Evaluation System

针对目前教学评价体系中存在的评价内容和评价方式单一、评价行为严重滞后等问题,提出了一套实时双向教学评价体系。为保证实时性,划分了详尽的评价阶段,为学生和教师的不同评价阶段设置了不同的评价内容,并给出获取评价数据的平台和软件架构,最终给出定量评价方法和定性评价方法。对于定量评价方法,给出了基于相关系数的抽象算法模型,对于定性评价方法,给出了基于自然语言处理技术的软件架构。利用本文给出的抽象模型和思路,可实现一套实时的、双向的、科学的、客观的评价体系,进而提升教学效果。

Aiming at the problems existing in the current teaching evaluation system,such as the simplicity of content and limited mode of evaluation and the serious lag of evaluation behavior,the paper proposes a real-time two-way teaching evaluation system.In order to ensure real-time performance,detailed evaluation stages are divided,different evaluation contents are set up for different evaluation stages for students and teachers,the platform and software architecture for obtaining evaluation data are provided ,and finally quantitative and qualitative evaluation methods are produced.For the quantitative evaluation method,the abstract algorithm model based on correlation coefficient is introduced,and for the qualitative evaluation method,the software architecture based on natural language processing technology is proposed. Using the abstract model and ideas given in this paper,a real-time,two-way,scientific and objective evaluation system can be realized,and the teaching effect can be improved.
