ABSTRACT This paper examines the debate in recent years about the most effective strategy for establishing the use of information technology in teacher training establishments in the United Kingdom. Evidence is presented to support the notion that efforts should continue to permeate the use of information technology throughout the courses of such establishments. However, the paper suggests that staff development and the degree of permeation of information technology within the culture develop alongside each other. As one of these variables change, it feeds the development of the other; neither is an independent variable though both are influenced by external factors. Recognising this as a relatively slow process, the paper proposes a model of evolutionary permeation. 相似文献

How does the effectiveness of guiding cues influence the development of motor skill autonomy? We utilized two sets of guiding cues (lights vs. reversed-lights conditions) that differed in their effectiveness to control a left–right leverpress sequence in rats. We separately measured the development of stimulus control by panel lights on guiding-cues trials and the development of stimulus control by practice cues on no-cue probe trials within the same sessions. Accuracy in the presence of the guiding cues was acquired faster in the lights condition than in the reversed-lights condition, but subjects in the reversed-lights condition were more able to complete the skill autonomously than those in the lights condition. Throughout acquisition, control by guiding cues and practice cues developed at the same rate in the reversed-lights condition, but control by practice cues (autonomy) developed at a slower rate than did control by guiding cues in the lights condition. At the end of training, subjects that had been exposed to the reversed-lights condition displayed higher levels of autonomy than did those exposed to the lights condition. The less effective guiding cue (reversed-lights) produced greater levels of autonomy than did the more effective cue (lights), even though control by this guiding cue developed more slowly. Thus, guiding your child by the hand too much may reduce his or her ability to complete the task independently. We discuss the similarity to prompt dependence in children with learning disabilities and transfer of stimulus control. 相似文献

A vast literature on technology transitions within industries suggests that early phases of new technologies are marked by periods of intense experimentation, but we know little about the conditions under which these periods emerge. We apply inductive, grounded theory-building techniques to examine what prompts firms to experiment across one emerging technology platform—plug-in electric vehicles (PEVs)—in China. Triangulating annual vehicle make and model sales data from 2003 to 2016 (plus monthly data from 2010 to 2016); 112 English and Mandarin archival documents from industry, academic, and news outlets; and 51 semi-structured interviews with industry, government, and academic stakeholders, we develop four in-depth case studies. We find that in contrast to the innovation trajectories of multinational and Chinese arms of joint venture (JV) firms, independent domestic Chinese firms (those with no history of international JV partnerships) are undertaking significant experimentation across multiple levels—infrastructure, core system, subsystem, and component—of the emerging PEV technology platform. We propose the concept of “institutional complementarities” to describe how interactions among institutions—here the national JV regulation and local market support and subsidies—may have turned regional markets into protected laboratories, extending the incubation periods for independent domestic firm experimentation. While this diverse experimentation may be an important antecedent of technology transition, consolidation induced by national policy standardization or competitive pressure may be required for PEV innovations to scale beyond their early, protected regional markets. 相似文献

Despite an increase in the use of technology in undergraduate anatomy education, and the rising popularity of online anatomy courses at community colleges in the United States, there have been no reports on the efficacy of augmented reality on anatomy education in this population. The purpose of this study was to test the hypothesis that augmented reality is an effective and engaging tool for learning anatomy in community college students. Participants recruited from Cuyahoga Community College (Cleveland, OH) studied skull anatomy using either traditional tools (i.e., textbook and plastic skull model) or an augmented reality head-mounted display with an interactive virtual skull application. Comparison of knowledge before and following the study period revealed that augmented reality was an effective tool for learning skull anatomy: pre-quiz = 32.7% (± 25.2); mean (± SD), post-quiz = 61.8% (± 19.5); n = 15; t(28) = 3.53; P = 0.001. The traditional tools were equally effective: pre-quiz = 44.9 % (± 18.6), post-quiz = 67.9 % (± 17.3); n = 17; t(32) = 3.73; P = 0.0007. Students rated the augmented reality device as 9.6 (± 1.0); mean (± SD) when asked if it fit the statement “fun to use” on a semantic differential scale from 1 (poor) to 10 (excellent). In conclusion, this study found that augmented reality is an effective and engaging tool for the instruction of skull anatomy at a community college. 相似文献

Research Findings: The current study examined how children’s parent-reported compliance at age 3 (36 months) moderated the effects of 2 dimensions of directly observed early care and education (ECE) process quality (positivity/responsivity and cognitive stimulation) during the prekindergarten year (54 months) on teacher reports of children’s classroom cooperation in the fall of kindergarten. Compliance at 36 months and cooperation in kindergarten are operationalized as overt, behavioral aspects of self-regulation as appraised by parents and teachers. The sample consisted of 996 children from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development who attended formal or informal ECE settings during the prekindergarten year. Results indicated that children with low compliance at age 3 tend to demonstrate stronger cooperation skills by kindergarten when they experience more positivity/responsivity from their ECE caregivers. Main effects of positivity/responsivity and cognitive stimulation on classroom cooperation were not detected for the overall sample. Practice or Policy: The discussion addresses the importance of preparing and empowering ECE providers to help young children who enter the preschool period struggling with behavioral aspects of self-regulation, such as compliance, to improve these skills through positive and responsive caregiving. 相似文献

Citation analysis is a valuable method for tracking the growth and transmission of scientific knowledge. In criminology and criminal justice, such analyses tend to be focused on “classic” works or on highly cited scholars over many years. As an alternative approach, we focus on work that has been cited rather quickly – what we term the “early onset” of impact. In doing so, we identified 221 of the most highly cited peer-reviewed articles, authored by 480 scholars, which were published in criminology and criminal justice journals between 2010 and 2015. Analyses reveal wide variation in substantive topics and methodological approaches, as well as a substantial gender gap with respect to authorship. Additional analyses provide insight into both journal and institutional/program prestige. We conclude with directions for future research and stress the importance of tracking over time articles that appear to be off to an early start with respect to scholarly impact. 相似文献

Treatment of minority groups in textbooks has traditionally been studied by subjective means. This factor has rendered the research, despite its volume, essentially noncumulative. Evaluative Coefficient (ECO) Analysis was designed to provide a valid quantitative index of the evaluative treatment of a subject by a communication source. Use of the instrument in an analysis of evaluative treatment of four minority groups in history textbooks used in Ontario schools revealed significant differences among evaluations accorded to the different minorities, and between different classes of textbooks. The ability of ECO Analysis to produce a quantitative measure of evaluation, along with its relative simplicity, suggests its potential for further comparative analysis of textbooks and of other communications content.

Young Children Understand That Looking Leads to Knowing (So Long as They Are Looking into a Single Barrel) 总被引:5,自引:0,他引:5
3 experiments were conducted to investigate the claim made by Wimmer, Hogrefe, and Perner that 3-4-year-old children do not understand that people gain knowledge about something by looking at it. The first experiment involved a simple forced-choice procedure in which children had to judge which of 2 assistants knew what was inside a box when one of the assistants had looked inside and the other had lifted it up. In this experiment, the children did realize that the assistant who had looked in the box knew its contents. The second experiment followed the Wimmer et al. procedure, but with a simpler question form. The children were just asked to state whether someone knew what was in the box. Again, the children were able to work out that a person who had looked in a box knew what was inside it. In the third experiment, a direct comparison was made between the simpler question and the more complex, double-barreled question asked by Wimmer et al. The children found the more complex question considerably harder. The results of these experiments suggest that, in contrast to the claims made by Wimmer et al., 3- and 4-year-old children do understand that looking leads to knowing, and that their difficulty in the Wimmer et al. study was mainly with the form of the question that they were asked. 相似文献
