基于层次分析法的多媒体教材评价体系研究

On the Multimedia Teaching Material Evaluation System Based on the Analytic Hierarchy Process

建立科学合理的评价体系是评价多媒体教材建设与开发的关键技术,也是衡量多媒体教材质量的重要方法。通过文献检索与问卷调查,结合国内外对多媒体教材质量的研究与功能特色的描述,从教材的本质属性入手,构建了7个一级评价指标和26个二级评价指标的多媒体教材评价体系。运用层次分析法,计算指标体系中目标层W和准则层Wi的各个指标权重向量,通过层次单排序和层次总排序建立判断矩阵,检验矩阵的一致性。并结合《视听说》多媒体教材,验证该评价指标体系的合理性与正确性,以确立具有层次结构和多项评价指标、能够广泛适用于不同专业类型和不同层次水平的多媒体教材评价指标体系。

The construction of scientific evaluation system is the key of technology to assess the construction and development of multimedia teaching material,also an important way to measure the quality of multimedia teaching material. Through literature searches and surveys,based on the quality of multimedia teaching material study and the description of its functions and features,starting from the nature of the textbook,the paper builds 7 indicators of first- level evaluation and 26 indicators of second- level evaluation for the multimedia teaching material evaluation system. The paper applies the analytic hierarchy process to calculate the weight of each indicator of target-level W and criterion- level Wi in the indicator system,construct the judging matrix by level single sorting and total sorting,and check the consistency of matrix. Combining with the Audio- visual- speaking Multimedia material that is in use,the paper verifies the reasonableness and correctness of the evaluation indicator system as well,to establish a widely used evaluation index system of multimedia teaching material of hierarchies and multiple indexes in different professional types and levels.
