II-NEW: Exploration of Social Trust in Mobile Educational Environments

先进的无线技术允许用户随时随地进行通信，随着各种手持移动设备的普及，无线社区变得无处不在。这些社区与传统的基于互联网的在线社区非常不同，在传统的社区中，人们彼此联系，但既不认识彼此，也不一定关心他们在任何特定时刻的位置。相比之下，在无线社区中，人们通过共享共同的物理和/或社会环境而更加紧密地联系在一起。这项规划赠款探索了教育环境中的小型“游牧”和“定居”无线社区，以及在这些移动学习社区（MLC）中使用教育服务时的社会信任方面。pi开发了一个有限的移动无线测试平台，具有混合无线点对点和基于基础设施的连接，以及一套确保信任的教育服务，以mlc工具包的形式提供给选定班级的学生。pi在一个小的MLC群体中验证MLC工具包，并根据班级/用户活动的类型、学生的积极参与和学生的流动性（游牧与定居）来探索社会信任。pi还探讨了社会信任的保证来自何处，例如，来自朋友及其各种类型的关系（强关系与弱关系），和/或来自底层的软件和硬件基础设施。其影响在于开发和部署mlc工具包，以及理解社会信任指标及其与用户和底层基础设施的关系。

Advanced wireless technologies allow users to communicate anytime and anywhere and wireless communities are becoming ubiquitous with the proliferation of various handheld mobile devices. These communities are very different from traditional Internet-based online communities in which people are connected with one another but neither know each other in person nor necessarily care where they are at any specific moment. In contrast, in wireless communities, people are much more closely bound to each other through a sense of sharing a common physical and/or social context. This planning grant explores small 'nomadic' and 'settled'- like wireless communities in educational environments and the social trust aspects when using educational services within these mobile learning communities (MLC). The PIs develop a limited mobile wireless testbed, with hybrid wireless peer-to-peer, and infrastructure-based connectivity, and a small set of trust-ensuring educational services, made available in the form of a MLC-toolkit to students in a selected class. The PIs validate the MLC- toolkit in a small MLC group and explore the social trust depending on the type of class / users activity, active participation of students, and mobility of students (nomadic versus settled). The PIs also explore, where the assurance of social trust comes from, e.g., from friends and their various types of ties (strong versus weak ties), and/or from the underlying software and hardware infrastructure. The impact is in developing, and deploying the MLC-toolkit, and understanding social trust metrics and their relations to users and underlying infrastructures.
