How groups cooperate in a networked geometry learning environment     

Kevin Lai  Tobin White 《Instructional Science》2014,42(4):615-637

This paper presents a small group computing environment in which four students each control a different point in a geometric space, such that as a group they collectively manipulate the vertices of a quadrilateral. Prior research has revealed that students have considerable difficulty in learning about the interrelationships among quadrilaterals shapes. In this study, we investigated how a designed environment can help support students’ learning in this area. In particular, in a case study of two student groups, we used the notions of appropriation and objectification to explain how students learned from one another different ways of using the technology and of explaining geometric concepts to progress in their geometric reasoning. When the students did not attain a shared focus of attention, they were not able to appropriate others’ approaches to using the technology or explaining geometric concepts. In one group, although some individuals demonstrated learning gains, when the coordination among the group members fell apart, not all the members were able to benefit. On the other hand, another group which demonstrated more group-oriented behavior—listening to one another, sharing the same focus of attention, engaging in coordinated actions—was able to benefit as a whole and did better overall on individual assessments.  相似文献   

Investigating Cheaters     

Mimi White 《The Communication Review》2013,16(3):221-240

This article analyzes the American television program Cheaters. Cheaters advances itself as the most “realistic” of reality programs based on an ethnographic approach to the surveillance and exposure of infidelity. The program offers theoretical lessons in the vernacular of reality television, as it proliferates positions for the subjects in its narrative and raises questions about the relationship between seeing and believing. Every effort to show and tell more destabilizes the possibility of discerning the very truths it purports to uncover. In the process the program offers insights into the limits of reality television and into contemporary socio-cultural epistemology.  相似文献

Net Neutrality and Libraries: Conflicts of Access     

Sara White 《期刊图书馆员》2013,64(2):151-157

The United States Court of Appeals for the District of Columbia Circuit recently heard a suit brought against the Federal Communications Commission by Verizon concerning the 2010 Open Internet Rules. These rules were meant to protect consumers and ensure net neutrality by Internet service providers (ISPs). The Court struck down these rules, and now ISPs will have more power about how content is delivered to users. Librarians should be knowledgeable of net neutrality and this ruling, as it potentially affects abilities of users to exercise intellectual freedoms and could impact the library’s ability to provide services to its users.  相似文献   

A content analytic technique for measuring the sexiness of women's business attire in media presentations     

Sylvia E. White 《Communication Research Reports》2013,30(2):178-185

This study describes the development and pretest of a content analytic category scheme for objectively measuring the sexiness of women's business attire in media presentations. In a test of the validity of the category scheme, presentations of women's business attire in television soap operas were compared to real world examples. The television samples were found to be significantly more provocative than the real world attire. In addition, the results of the content analysis of soap opera attire was compared to an intuitive perception of “sexiness.” A significant positive correlation was found between the degree of sexiness as measured by the content analytic category scheme and subject's perception of sexiness.  相似文献

Collaborative knowledge-making in the everyday practice of youth suicide prevention education     

Jennifer White  Jonathan Morris  Jerry Hinbest 《International journal of qualitative studies in education》2013,26(3):339-355

The development and implementation of a new school‐based suicide prevention education programme in one secondary school in Vancouver, British Columbia, recently provided us with an opportunity to conduct an in‐depth, qualitative case study. The purpose of our study was to deepen our understanding of how school‐based suicide prevention education programmes like this one get planned and enacted in particular, local settings. We argue that the narrow range of methodologies that have traditionally been deployed to study school‐based youth suicide prevention education programmes have hindered our ability to see the complexities and potentialities of this work. Through the presentation of a sub‐set of findings, we aim to show the possibilities for fresh thinking and contextualized understandings that a qualitative case study, informed by a constructionist methodology, invites.  相似文献
