开源教学平台的可用性研究——以Sakai为例

越来越多的国内外高校开始考虑使用基于开源软件的网络教学平台,在投入使用之前,开源教学平台一般需要进行二次开发过程,其中需要重点解决平台的可用性问题,因为网络教学平台的可用性是影响学习效果的重要因素.发现并解决网络教学环境中的可用性问题,是促进人机交互、提高学习效率的重要途径.开源教学平台的可用性指的是系统的有效性、效率和满意度,分析了网络教学平台的可用性诉求,并以浙江大学Sakai开放学习平台为例,进行个案研究.使用了ThinkAloud、观察法和访谈法等可用性测试方法,研究结果发现,浙江大学Sakai开放学习平台主要功能人机交互设计合理,但是由于文化差异和用户使用习惯问题,部分功能存在一定的可用性问题,值得学习平台设计者借鉴.

Usability Testing on Open Source Software-based E-Learning Platform: A Case Study of Sakai

Usability of open source software-based e-learning platform,which includes effectiveness, efficiency and user satisfaction of the platform,is one of the most influential factors impacting student's online learning experience.The purpose of this study is to evaluate an open source software-based learning management system SAKAI by using Performance Analysis and User Perception methods.The major task is to investigate the system's efficiency, effectiveness and user satisfaction.In this study,efficiency and effectiveness were evaluated by Time on Task and Task Completion score,and user satisfaction was assessed by Interviews. Based on our findings,this article identified some usability problems caused by culture issues, and provided some suggestions for interface designers of e-Learning Platforms.
