This article addresses the question of whetherpersonal surveillance on the world wide web isdifferent in nature and intensity from that inthe offline world. The article presents aprofile of the ways in which privacy problemswere framed and addressed in the 1970s and1990s. Based on an analysis of privacy newsstories from 1999–2000, it then presents atypology of the kinds of surveillance practicesthat have emerged as a result of Internetcommunications. Five practices are discussedand illustrated: surveillance by glitch,surveillance by default, surveillance bydesign, surveillance by possession, andsurveillance by subject. The article offerssome tentative conclusions about theprogressive latency of tracking devices, aboutthe complexity created by multi-sourcing, aboutthe robustness of clickstream data, and aboutthe erosion of the distinction between themonitor and the monitored. These trendsemphasize the need to reject analysis thatframes our understanding of Internetsurveillance in terms of its impact onsociety. Rather the Internet should beregarded as a form of life whose evolvingstructure becomes embedded in humanconsciousness and social practice, and whosearchitecture embodies an inherent valence thatis gradually shifting away from the assumptionsof anonymity upon which the Internet wasoriginally designed. 相似文献
Policymakers worldwide consider participation in adult learning beneficial for employability, in particular for specific target groups. However, still little is known about the effect of adult learning pursued by low-qualified young adults on their employment prospects. On the basis of a Flemish longitudinal database, we study the determinants and effects of work-related adult learning and adult learning not related to work. We make a distinction between formal learning and informal learning and between enrolment duration and qualification attainment. We control for background characteristics, human capital, school leaving age and entry into the labor market and run two path models. The analysis results contradict the general observation that adult learning is primarily a matter of high-qualified people. Among the low-qualified, lack of human capital does not hamper but encourages participation in adult learning. In addition, gender differences exist in participation in adult learning with men participating more often in work-related adult learning and women being more likely to attain a qualification in adult learning not related to work. Finally, our results indicate that participation but not qualification attainment in adult learning has an impact on employment prospects for low-qualified young adults. 相似文献
Mathematical modeling is a high-leverage topic, critical for college and career readiness, participation in STEM education, and civic engagement. Mathematical modeling involves connecting real-world situations, phenomenon, and/or data with mathematical models, and in this way applies across various STEM disciplines, including mathematics, engineering, and science. Although research has begun to explore mathematical modeling instruction in the elementary grades, questions remain about how to assess student learning at the elementary level. We addressed this need by designing an assessment of mathematical modeling competencies for students in grades 3 through 5. Informed by international research, our assessment includes a hybrid structure to assess mathematical modeling competencies holistically (as students engage in the complete modeling process) and atomistically (as students engage in different components of the modeling process, including making sense of phenomena and real-world situations, setting up and operating on mathematical models, and interpreting results in relation to the real-world context). We conducted student interviews, followed by two rounds of pilot testing to inform item development and ensure acceptable psychometric properties. The final assessment included 13 items (9 multiple choice, 3 open-response, and 1 complete modeling task). We describe our assessment development process, and provide sample assessment items and detailed coding rubrics. We summarize quantitative analyses which established high reliability and low standard error for our assessment, supporting its use for grades 3 to 5. Implications of our framework and assessment for mathematical modeling instruction and future research on STEM learning are discussed.
This paper explores the successful mentoring of Timor-Leste early years teachers by Australian teachers to expand their knowledge and practice of child-centred play-based pedagogy. The mentoring programme for the Timorese teachers occurred through an extended visit to a school in Victoria, Australia, for eight weeks to work with mentor teachers in their early years classrooms. Data were collected to explore the effectiveness of the programme through classroom observations and participant interviews. Observations were conducted in the classrooms of the mentees before the programme to provide context for the interviews and after the programme for indications of pedagogical change. The mentoring programme supported the Timorese teachers to reflect and review early years pedagogy. It led to changes in their teaching philosophy, design of learning activities and the inclusion of assessment practices. After two years the Timor-Leste teachers were using a child-centred play-based model of teaching and learning to guide the development, organisation and facilitation of learning activities at their kindergarten. The foundation of the mentor programme’s success was the trusted and equitable relationships between the teachers and the organisations involved. Understanding of cultural differences was acknowledged and supported the robust discussions and reflections that empowered teachers to take action. 相似文献
