图书馆移动阅读服务的新契机:HTML5和CSS3

针对移动阅读环境和用户需求的变化与现有移动Web标准规范如WAP、WML、XHTML-MP对移动Web发展的不适应,以及图书馆在旧的移动Web标准规范框架下的移动阅读服务在内容、应用架构、服务模式方面的诸多困境,用文献调研和实验验证的方法研究新的Web标准规范HTML5和CSS3的新特性和功能及其相对应旧标准的优点,从HTML5和CSS3对图书馆上游的数字出版领域和图书馆下游的用户需求的直接影响的角度,探讨HTML5和CSS3为图书馆移动阅读服务带来的新契机,得出HTML5和CSS3可使图书馆的移动阅读服务在内容、应用架构、服务模式方面得到提升和变革的结论。     

Learning design and learning analytics in mobile and ubiquitous learning: A systematic review

Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes.     

Affordances of video-based professional development for supporting physics teachers' judgments about evidence of student thinking

This study explores the affordances of a video-based professional development workshop for supporting physics teachers' content-specific judgments about evidence of student thinking. We rated both the quality of teachers' discussions and the judgments that resulted as they discussed video clips highlighting student thinking. We found that teachers' judgments were related to the quality of their discussions. Quantitative and qualitative analyses suggest that elaborated focus questions and interactions with colleagues may support teachers with relatively little physics teaching experience in using their collective wisdom to engage in a situation-specific skill necessary for responsive teaching.

Design and performance attributes driving mobile travel application engagement

Increasing people are using mobile applications (apps) for information and activities related to their travel and tourism. Therefore, customer engagement (customer attraction and retention) with mobile travel applications becomes extremely important for travel-related companies. However, there is little empirical research on what factors may drive customers’ engagement of using mobile travel apps. This study proposes a research framework, based on the Stimulus-Organism-Response (S-O-R) model, to explore how and to what extent two types of app attributes (i.e., app design and app performance attributes) stimulate travel apps engagement. Based on a user acceptance testing (UAT testing) of a real travel app development project, the study uses survey data from 804 tourists to validate the proposed research model. The results reveal different effectiveness of app design and app performance attributes, and demonstrate that two app design features (i.e., user interface attractiveness and privacy/security) and three app performance attributes (i.e., compatibility, ease of use, and relative advantages) are important drivers of users’ behavioral engagement of mobile travel apps. Further, psychological engagement and three types of benefit perception (i.e., hedonic benefit, utilitarian benefit, and social benefit) serially mediate the relationships. The results can be used to improve the related mobile app engagement research and the mobile travel app design.

TOE框架下的省级政务大数据发展水平影响因素与发展路径——基于fsQCA实证研究

[研究目的]大数据赋能政府数字化转型已经成为国家治理体系和治理能力现代化的重要抓手。然而,严重的“数字鸿沟”问题依旧是制约我国政务大数据整体发展水平提升重要瓶颈。如何因地制宜发展政务大数据,破解“数字鸿沟”难题亟待学界探究。[研究方法]将TOE框架与中国具体的治理情境相结合,运用模糊集定性比较分析法(fsQCA)对全国31个省(自治区、直辖市)政务大数据发展水平的影响因素与发展路径进行了研究。[研究结论]研究结果表明,省级政务大数据发展水平受到技术、组织和环境三个层面因素的综合影响;其次,共有7种实现省级政务大数据高水平发展的路径;根据主导因素的差异,7种发展路径可归纳为:黄牛型(组织驱动型)、脱兔型(技术驱动型)和雄狮型(技术-组织驱动型)三大发展模式。黄牛型和脱兔型应尽可能向雄狮型的发展模式转变。
