【摘要】：随着互联网技术的发展和计算机的普及,教育行业正迎来一场深刻的变革。传统课堂教育已不能满足人们的学习需求,一种基于网络教学平台的、更为高效便捷、简单易用的在线学习方式正走进人们的生活之中,并受到了广泛的关注和好评。在线学习平台作为网络学习和教育的载体,其可用性特征影响着用户的使用体验和使用满意度,并因此引起了广大学者的研究和探讨。本文以某在线学习平台为例,从一般用户的角度出发,围绕在线学习平台的可用性分析与改进的主题展开。首先介绍了课题研究的背景和意义,描述了在线学习平台可用性研究的必要性,并基于大量相关文献的阅读和总结,阐述了在线学习平台发展现状和在线学习平台可用性的研究现状,掌握了在线学习平台可用性研究的重点和方向。其次,展开了一般在线学习平台的用户分析、视觉元素分析和交互方式分析,结合现有的可用性评价准则和可用性测试方法,确定了本文的研究思路技术路线,即基于可用性分析完成对在线学习平台的改良设计。在可用性测试环节,本文采取了可用性测试试验辅以用户深度访谈的方法进行。通过分析任务绩效度量、用户有声思维和用户深度反馈,从视觉界面、功能布局、信息架构三个层面完成了对于在线学习平台的可用性评价,深刻剖析了在线学习平台的可用性特征和问题缺陷,在此基础上,提出了包含美观性、一致性、状态可见性、易用性等9个维度的可用性评价准则。再次,基于可用性分析结果,从结构设计、视觉设计和交互设计三个方面展开了具体可行的、针对性的改良设计,改善了平台的层级架构、页面布局、色彩搭配、图形图标、功能布局等内容。最后,结合纸面原型法和语义差异评价量表法,完成了改良设计前后的该平台的可用性对比测试试验。量化数据分析表明,改良设计显著改善了平台的可用性,提升了用户满意度。本文以某在线学习平台为研究实例,详细阐述了在线学习平台的可用性测试和评价过程,并基于可用性研究结果展开了针对性的综合改良设计,再次进行的可用性测试结果验证了改良成效,为一般在线学习平台可用性的设计和改善提供指导。
[Abstract]:With the development of Internet technology and the popularization of computers, the education industry is undergoing a profound change. Traditional classroom education has not been able to meet people's learning needs. A more efficient, convenient and easy to use online learning method based on network teaching platform is coming into people's life, and has been widely concerned and praised. As the carrier of online learning and education, the usability characteristics of the online learning platform affect the user's use experience and satisfaction, which has aroused the research and discussion of the majority of scholars. Taking an online learning platform as an example, this paper focuses on the usability analysis and improvement of an online learning platform from the point of view of general users. Firstly, it introduces the background and significance of the research, describes the necessity of the usability research of online learning platform, and based on the reading and summary of a large number of related literature, This paper expounds the present situation of the development of online learning platform and the present situation of research on the usability of online learning platform, and grasps the emphasis and direction of the research on the usability of online learning platform. Secondly, the user analysis, visual element analysis and interactive mode analysis of the general online learning platform are carried out. Combining with the existing usability evaluation criteria and usability testing methods, the paper determines the technical route of this research. Based on usability analysis, the improved design of online learning platform is completed. In usability testing, this paper adopts the method of user depth interview and usability test. By analyzing task performance measurement, user voice thinking and user depth feedback, the usability evaluation of online learning platform is completed from three aspects: visual interface, function layout and information architecture. This paper deeply analyzes the usability characteristics and defects of the online learning platform, and puts forward the usability evaluation criteria including 9 dimensions, such as aesthetics, consistency, state visibility and ease of use. Thirdly, based on the results of usability analysis, the concrete and feasible design is carried out from three aspects of structure design, visual design and interactive design, which improves the level structure, page layout, color collocation, graphic icon of the platform, and improves the level structure of the platform, the layout of the page, the collocation of color, and the graphic icon. Function layout, etc. Finally, the paper prototype method and the semantic difference evaluation scale method are combined to complete the usability comparison test of the platform before and after the improved design. Quantitative data analysis shows that the improved design significantly improves the platform availability and user satisfaction. Taking an online learning platform as an example, this paper describes the usability testing and evaluation process of the online learning platform in detail, and develops a comprehensive and improved design based on the results of usability research. The results of the usability tests have proved the effectiveness of the improvement and provided guidance for the design and improvement of the usability of the general online learning platform.
