This article argues that commodity flow is a defining characteristic of children's television programming, and that this flow of commodity and corporate-brand images builds into the genre a relatively coherent selling ethos. Three-hour blocks of programming, recorded on two different Saturday mornings for several broadcast and cable networks, were analyzed to highlight commodity flow within and between networks. This flow of commodities on children's television indicates a blurring of the distinction between content and promotional forms and illustrates the high level of commercialism targeted at this audience. 相似文献

This article explores the changing relationship between the academy and new public formations of scientific research, which we term “civic technoscience.” Civic technoscience leverages tactics seen in critical making communities to question and transform how and who can make credible and actionable knowledge. A comparison of two case studies is used. The first is a grassroots mapping process that allows communities to generate high-quality aerial imagery. The second is an academic-led project using environmental sensors to engage disparate audiences in scientific practice. These two projects were found to differ in their ability to form strategic spaces for community-based science, and suggest pathways to foster more robust relationships across the public–academic divide. By altering power dynamics in material, literary, and social technologies used for scientific research, we argue that civic technoscience enables citizens to question expert knowledge production through critical making tactics, and creates opportunities to generate credible public science. 相似文献

The decline in the popularity of physics over the period of secondary schooling and its consequent low uptake at A‐level and beyond continues to cause concern on educational and economic grounds. The aim of this study is to explore whether physics might be made more attractive to students by employing an extended range of classroom and laboratory activities to teach it. Specifically, the study scores the popularity of a range of activities, students’ perceptions about how often these activities are used to teach physics, and whether students consider them educationally useful. Students appear to think in terms of written activities, passive activities, social activities and constructive activities. Written activities are relatively unpopular and seen as educationally less effective, but students perceived them as used frequently. Social activities such as group work are more popular. The most popular activities are constructive activities, such as doing experiments; these are seen as educationally useful, but are perceived as being used less often than other activities. While there are legitimate limitations on the types of activities that can be used, these findings add to our appreciation of which teaching activities students like and value. 相似文献

The current study examines whether students' course of study is related to their desire to carry a concealed handgun on campus. This analysis is motivated by a growing number of studies that have explored differences between criminal justice (CJ) and other majors in the areas of personality, attitudes, values, and career expectations, and also by discussions of the issue of concealed handguns on campuses following recent shootings on college campuses. Using data from over 3,100 students who completed an online survey instrument, results revealed that CJ majors were in fact more interested in carrying a legally concealed handgun on campus, if it were allowed by university policies. These results held even when controlling for other significant predictors of the desire to carry a concealed handgun. Implications for CJ education and the wider debate about concealed weapons on university campuses are discussed. 相似文献

A number of policymakers have shifted their attention from the participation rates of Hispanics in postsecondary education to the percentage of this population that completes a baccalaureate degree. Several reports stress that while participation rates have increased, there are continued disparities in outcomes between Hispanic and White college students (President's Advisory Commission on Educational Excellence for Hispanic Americans, 2003; Council of Economic Advisers, 2000; Fry, 2002; Vernez & Mizell, 2001). Although many states have experienced increases in Hispanic postsecondary attendance, such is not the case in Texas—a state with one of the largest Hispanic populations in the country. Figures for 2003 show that 3.9% of Hispanics in Texas were enrolled in some type of postsecondary institution compared to 5.2% of African Americans and 5.6% of Caucasians (Haurwitz, 2005). 相似文献

ABSTRACTThis study investigated split-step timing when returning serves and whether this timing is related to neuromechanical capabilities in world-class tennis players. In Experiment 1, the split-step timing of four groups of world-class players (male and female ATP/WTA seniors, and ITF juniors) was measured on court when returning serves of the same level players. The four groups initiated the split-step at a similar time, starting around the time ball-racket contact in the serve stroke and landed when early ball-flight information was available. In Experiment 2, the neuromechanical capabilities (leg stiffness and vertical jump performance) of a group of world-class players and three groups of less-skilled tennis players were examined. The results showed an increase in leg stiffness with an increase in the level of expertise. A cross-experiment analysis in world-class male players (ATP/ITF, n = 10) revealed that the timing of initial foot movement was significantly correlated with the leg stiffness (r2 = 0.54), with later lateral step after the serve in the players who had higher stiffness. The findings support the hypothesis that world-class tennis players adapt perceptual-motor control on the basis of their neuromechanical capabilities and maximise the time before initiating their interceptive action to rely on more reliable information. 相似文献

In this article we describe the evolution of an elective course designed specifically for undergraduate students in our pre-service teacher education program. This course is intended to prepare these undergraduate students as future teachers—helping them to make effective and creative uses of technology in learning settings. This course emphasizes learning to learn with and about technology, in the ever-changing context of educational technology. Generally speaking, we outline and describe three key goals of teaching young teachers to thoughtfully integrate technology into a real-world classroom. First, the course emphasizes learning to explore and learn proactively by engaging in learning by design activities. Second, students are given an opportunity to try a wide variety of innovative technologies through explorations of their own choosing. Finally, we attempt to leverage the power of online community building for learning by harnessing the ubiquity and convenience of tools like Facebook. We look into the future with great hope and enthusiasm that our preservice teachers will lead the way in integrating new technologies into their teaching in ways that will benefit their students, colleagues, and the greater education community. 相似文献

ABSTRACTPolicy and program language in the UK and Australian higher education sectors consistently deploys the term aspiration in ways that adhere to the hegemonic neo-liberal ideal of the entrepreneurial competitor-individual, de-meaning and de-valuing ‘other’ personhoods. University Equity and Widening Participation (EWP) outreach programs that engage with marginalised groups in school and community settings challenge people to perform particular aspirations from what can be a deeply uncertain present. This paper presents a cautionary tale from the Australian Equity and Widening Participation (EWP) context that emerged from a research-informed practice PhD, spanning two methodologically different phases. The paper argues that the discursive framing of certain aspirations as legitimate works in subtle ways to shape the perceptual horizons of EWP practitioners and participants. Specifically, the work takes issue with policy frames that create conditions for misrecognition(s) that are themselves difficult to re/cognise. A metaphorical pedagogical tool is developed using the Ames Room illusion. 相似文献
