对于CAI课件质量评估问题,提出基于正则化BP神经网络.(RBPNN)智能化评估模型.分析评估活动相关环节,进而给出解决方案,包括对评估数据的区间化处理,减少指标集参数冗余.然后通过学习训练确定RBPNN的网络权值及其它参数,对RBPNN输出评语集给出模糊处理.由此给出解决问题的算法,最终通过一个实例来说明算法的使用,实验结果表明,该评估模型比较实用,完全满足CAI课件质量评估的技术要求.  相似文献

Web-based courseware are widely developed for distance learning programs in continue education, employee training center, and e-learning portals. Usually, a Web-based courseware contains course contents and on-line tests. However, most Web document development tools are not incorporated with a strategic evaluation mechanism, to allow a quantitative analysis of distance learning courseware. We propose an evaluation mechanism and a multimedia tool, based on our Courseware Diagram, to allow a quantitative justification of courseware. Courseware produced by our development system allows an instructor to choose different instruction sequences based on the outcomes of an exam. Alternatively, the courseware may allow self-guided study in a Web-based distance learning program. This paper explains the courseware diagram, the evaluation algorithm, and the design of our courseware development system.  相似文献

Assuring e-learning quality is of interest worldwide. This paper introduces the methods of e-learning courseware quality assurance (a quality certification system) adopted by the eLQSC (e-Learning Quality Service Centre) in Taiwan. A sequential/explanatory design with a mixed methodology was used to gather research data and conduct data analyses. Sixty-seven e-learning courseware applications were evaluated using the e-Learning Courseware Quality Checklist (eLCQC). Analyses of item difficulty, item discrimination and generalizability indicated that the eLCQC provides high-quality evaluations. After participating in the certification process, the e-learning producers reported having more confidence in enhancing e-learning courseware quality. The certification experience also helped the producers to change their previous design concepts about e-learning courseware and to develop new concepts; further, their increased confidence about courseware design also enhanced their confidence in marketing courseware.  相似文献

基于面向对象技术的积件系统的设计   总被引:3,自引:1,他引:3  
本文描述了一个基于面向对象技术的积件系统的设计思想及其工作原理,给出了该系统写作组合平台的设计和系统的课件运行的动态模型。该系统将积件对象化,面向对象积件库由积件对象组成,外部与积件对象、积件对象与积件对象之问只能通过消息发生联系。积件对象通过接受消息驱动相应的教学服务。这样的系统设计可增加积件的独立性与可积性,实现课件的动态重组。  相似文献

The main objective of the study was to develop systematic methods for improving CAL materials by comparing the five coursewares which were produced by independent authors and related to high school mathematics, science and engineering. Various kinds of evaluation were undertaken before, immediately before, during and immediately after CAL implementation; e.g. evaluators check on the drafts for courseware; evaluators check on the problems encountered in each frame while studying at the terminals; the readiness, pre- and post-tests; an anxiety scale; questionnaires for assessing any difficulties with learning in each chapter and each course; the course test; an image scale, an attitude scale and a line-connecting type of content analysis. Each courseware was evaluated and compared with others on the basis of the data analysis of tests and questionnaires as well as the learning history records, e.g., total learning duration, total number of passed frames, frequency of use of function keys, actual transitive path graph, actual average branch ratio, relative entropy in each frame and the index of educational effectiveness. A number of important evaluation items were selected by factor analysis. Finally an evaluation package instrument for improving CAL courseware were developed.  相似文献
