This paper draws upon archive material to explore the reasons for the absence of any drugs education films, or ‘mass-mediated drugs education’, during the immediate post-war period in Britain. The term ‘mass-mediated drugs education’ is used to refer to any drugs education messages communicated via the mass communication technologies of the twentieth century—the ‘high modern age’. While this might appear a rather narrowly defined interest in media history, the evidence offered in explanation provides some important insights into the assumptions made about mass media by British policy-makers and political elites during the ‘high modern age’ of mass communication. In contrast to Britain, during the same period in the United States, a plentiful supply of drugs education films was generated through the energies and interests of state agencies and moral entrepreneurs. Many of the US films of the ‘reefer madness’ era of the 1930s and the short ‘social guidance’ films of the fifties and sixties still remain in circulation, thanks to YouTube and other video file sharing sites where they are widely relished for their hysterical and wildly exaggerated treatment of the dangers of illicit drug use. However, in Britain there is an absence of any drugs education films or mass-mediated drugs education during the fifties and sixties, while the first government-sponsored mass-mediated drugs education was not produced until the mid-1980s, five decades after the first US films appeared. 相似文献

Teachers play a critical role in establishing the verbal and nonverbal environment in the early childhood classroom. Within this article, children's literature is used as a vehicle for enhancing understanding of (a) how teachers talk to children, (b) how teachers allow children to talk to each other in positive and reinforcing or negative ways, and (c) how teachers help children talk to themselves about their learning and participation in class. The role of the teacher as a positive, conscious, and deliberate model of self-regulated learning is promoted. 相似文献

This study examined whether children’s difficulties with stage‐salient tasks served as an explanatory mechanism in the pathway between their insecurity in the interparental relationship and their disruptive behavior problems. Using a multimethod, multi‐informant design, 201 two‐year‐old children and their mothers participated in 3 annual measurement occasions. Structural equation modeling analyses indicated that coder ratings of children’s insecure responses to interparental conflict from a maternal interview predicted observer ratings of their difficulties with stage‐salient tasks (i.e., emotion regulation, autonomy, resourceful problem solving) 1 year later after controlling for initial stage‐salient task performance. Stage‐salient task difficulties, in turn, predicted experimenter reports of children’s behavior problems 1 year later. Associations remained robust in the broader context of other pathways hypothesized in prevailing developmental cascade models. 相似文献

In today's educational climate, differentiated instruction is a common practice for students who need remediation; what is less common is to Differentiate Instruction for the advanced learner. Contrary to popular perceptions, advanced learners do not automatically differentiate instruction on their own. Students who have the potential to excel within the curriculum are sometimes ignored due to a variety of classroom challenges. Asking students about their interests and questioning their perceptions are places to begin differentiating for advanced learners. All children, including advanced learners, should have the opportunity to be challenged and to excel in their classroom curriculum. 相似文献

The paper reports the findings of evaluative research that attempted to rigorously assess the efficacy of a feed-forward, formative assessment intervention. The aim was to improve participants’ conceptions of quality, and hence improve the quality of a complex piece of summative assessment, by asking them to mark exemplars produced by former students. Feed-forward assessment has theoretical support in the literature, but empirical confirmation has been slight. Research findings were encouraging. A statistical model incorporating feed-forward was developed which accounted for a large effect in the improvement of results for the summative item. Importantly, there was improvement across student ability levels. Students, in the main, made accurate judgements about different levels of exemplar quality, although they had some difficulty discerning different pathways to high-quality products. Qualitative analysis indicated improved student conceptions of coherence and integration in the summative piece. 相似文献

Tkachev on uneven bars is a release and re-grasp skill performed using variations of preparatory longswing techniques; the reasons why different techniques are chosen remains unclear. This study examined kinematic and key release parameters specific to three distinct techniques with the aim of understanding the relative benefits of each. During two international artistic gymnastics competitions six arch, straddle and pike longswings preceding the straddle Tkachev were recorded using twin video cameras. Calibration and movement images were digitised and reconstructed using 3D DLT. Shoulder and hip angular kinematics, angular momentum and key release parameters were compared between techniques. In the arch longswing, the first and second hip functional phases began significantly earlier than the straddle or pike. No significant differences were established for release parameters although large effect sizes for horizontal release velocity and angular momenta about the mass centre and bar were reported between the arch and other two variants. Therefore, the arch variant may provide the opportunity to develop more complex combinations following the Tkachev. Providing insight into mechanical advantages of specific longswing techniques, and highlighting those that elicit desirable characteristics offers the potential to provide coaches with objective data on technique selection and ultimately skill development. 相似文献
