Researching Internet Communities: Proposed Ethical Guidelines for the Reporting of Results   总被引：4，自引：0，他引：4  

Storm A. King 《The Information Society》1996,12(2):119-128

Communication researchers and social scientists are quickly discovering the value of data that exists in the postings of members of Internet e-mail, Usenet, and real-time groups. The ability to communicate with one's peers, no matter how esoteric the interests, is causing an explosion in the number of new virtual communities. The interpersonal dynamics of these groups are increasingly coming under the scrutiny of academic research. The publicly available archived records of Internet virtual communities are being analyzed for a wide variety of research interests. The ability to do naturalistic observations of group dynamics, as they are exhibited in these exchanges of text, has captured the attention of many researchers. The institutional review boards of major universities are granting researchers exempt or expedited (exempt from full review) status for this work, due to the public nature of the notes being analyzed. These studies often involve the lack of informed consent, where the group members under study are unaware they are being monitored. There is a potential for psychological harm to the members of these groups, depending on the way results are reported. This article explores the ethical considerations that must be taken into account to protect cyberspace participants. The guidelines proposed are based on the American Psychological Association ethical guidelines for use of human subjects in research. An explanation is offered as to how such guidelines can best be applied to the study of Internet communities. The constructs of Group Accessibility (the public/private nature of the actual cyberspace occupied by a group) and Perceived Privacy (the level of privacy that group members assume they have) are defined and proposed as two dimensions by which individual Internet communities may be evaluated in order to assure the ethical reporting of research findings.  相似文献

体感交互技术在教育中的应用现状述评   总被引：1，自引：0，他引：1  

李青  王青 《远程教育杂志》2015,(1):48-56

体感技术是人机交互历史上的一次革命,它以躯体动作、声音等自然语言来操纵多媒体设备,提供了革命性的体验。目前,体感技术研究集中在感应精度与深度方面,在教育应用领域也有一些前沿探索和实验。该技术自体感游戏开始之际便进入了大众视野,在实现技术上可分为惯性感测、光学感测以及惯性及光学联合感测三类,微软的Kinect采用了光学测感和声学感知技术。在教育应用方面,体感游戏开始进入课堂,就取得了较好的影响。它在语言、数学、科学、物理、特殊教育等不同学科领域内均有应用,通过三个典型案例详细讨论了其具体的教学步骤。体感技术在教学中作为教/学工具、教学内容和教学环境,可用于情境化学习、个别化学习以及游戏化学习三类教学形式,并根据不同用途具有多个整合关键点。总之,体感技术应用在教育中具有体验优、多感官、以学生为中心和支持合作学习的优势,但现阶段在部署、教学法和评价上还存在一些问题。  相似文献   

Online interaction across three contexts: an analysis of culture and technological affordances     

Todd L. Sandel  Richard Buttny  Mary Varghese 《Journal of Intercultural Communication Research》2019,48(1):52-71

Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction.  相似文献
