Teachers' perspectives of changes in their practice during a technology in mathematics education research project

Teachers' perception of changes to their teaching practice, with respect to digital technology use in secondary school mathematics, during their participation in a research project are reported. Two case studies are presented of teacher perspectives illustrative of the range of perceived changes teachers made to their practice and positions along the ‘path of change’ during their participation in the project. Participating in a project supportive of teacher change and resulting in perception of substantial change was necessary, but not sufficient, to meet the goal of transformative use of digital technologies to increase the level of cognitive demand experienced by students.

图书馆领域社交网络应用研究述评与展望

随着网络技术的发展,社交网络逐渐成为一种文化现象,在图书馆领域的应用也日益受到关注,并成为图书馆现代化的一个重要特征。2007年,社交网络正式成为图书情报界一个新的研究方向,其应用从最初的BBS、娱乐化社交网络发展到现在的微信息时代。目前,社交网络应用于图书馆领域的相关研究主要涉及七个方面:社交网络的技术优势、以图书馆为中心的案例、社交网络服务的内容、用户使用态度、图书馆和馆员问卷调查、服务效果评价和存在的问题。结合社交网络技术发展趋势和图书馆自身特点,将来应从社交网络的危机管理、信息素养教育、社交网络评价和可持续发展等方面进行深入研究;应认识到社交网络是图书馆拓展服务的技术手段而非目的,图书馆应从技术理性回归到实现服务的价值理性。表1。参考文献74。

Elite coaching and the technocratic engineer: thanking the boys at Microsoft!

The primary purpose of this article is to provide an in-depth understanding of the manner in which surveillance technologies have become readily appropriated and utilised by elite Rugby Union coaches. It is conceded that positions adopted by populist writings commonly categorise the act of coaching as an educational activity that harnesses holistic intentions. Through reflecting upon semi-structured interviews with players located at an Aviva Premiership Rugby Union Club, we provide insight into an elite sporting institution that more accurately depicts coaching as a technocratic activity. The resultant analysis is critical in its review of surveillance mechanisms embedded in institutional practice, extending to the sports coaching setting, which explicate sinister rather than pastoral motives to enforce a disciplinary power that enhances the quantification of athletic performance. The article concludes by emphasising the impact of such practices upon establishing a sense of trust and the construction of self autonomous to the sporting domain. We argue that the emerging and steadfast acceptance of technology in the elite coaching environment is threatening to circumvent the learning potential of players by merely viewing them as functionaries. In adopting this position, we tentatively suggest that future research seeking to inform the practice of coaching and coach education should continue to pursue this critical dialogue to question whether, and to what extent, an overreliance on technology is becoming perceived as the ‘gold standard’ of professional practice amongst the coaching fraternity.     

Inaugural Essay

New to the Journal of Archival Organization, the “Technology matters in archives” column examines how technology affects archives and archivists. This inaugural column explains the nature of the column and sets the stage for topics and issues that it will address. It examines the meaning of the term technology. Further, the column explores the notion of technological dependence-- not just dependence on digital or electronic systems--as a lens in which to examine the archival enterprise in grappling with twenty-first century issues. Concluding with the suggestion that technology can be considered from three categorical points of view: soft (philosophical approaches and practices), medium (codified processes, guidelines and standards) and hard technology (hardware and software).
