Hai-Ning Liang 《Interactive Learning Environments》2013,21(1):53-75
Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information space of an ILE, a process which can be quite difficult and cognitively exacting as the information space becomes very large and complex. Proper design can make this process less exacting and, at the same time, facilitate better learning of the information space. However, this is not easy to do, especially for ILEs. Frameworks can assist in the effective analysis and design of interactive environments. However, there is lack of conceptual frameworks for guiding the analysis and design of navigation in ILEs. This paper tries to address this issue by presenting a framework which can be used to characterize navigation within ILEs. To create this framework, this paper brings together research from various disciplines, such as human-computer interaction design, educational multimedia design, cognitive technologies and learning sciences. This framework prescribes a three-stage process for designing and analyzing navigation: 1. content structuring; 2. information navigation modeling; 3. interface presentation structuring. By bringing these three stages together, it is intended to provide a conceptual framework to assist and guide designers in the proper analysis and design of navigation in ILEs. 相似文献

This study examines several key design elements of 37 academic library Web sites (members of the Association of Southeastern Research Libraries) and how they have changed between 2012 and 2015. While several studies have reviewed library Web sites looking for common design elements and content, the present work may be the first to look at the design elements of a large group of library Web sites over time. This study has two main goals: to present an objective analysis of the navigation and search interface designs at research university library Web sites, and to assess the usage of Web-scale discovery systems and content management systems in libraries. Other areas explored include when sites were most recently redesigned and whether sites have adopted a mobile-friendly, responsive design. Notable findings include a very high usage of Web-scale discovery systems, an increasing adoption of open source content management systems, and increasing implementation of responsive design. Also noted was a strong and growing standardization in navigation design. This study concludes with a review of the trends and discussion of current design patterns in academic library Web sites. 相似文献
