Abstract

Web-based instruction, also called e-learning, is currently one of the most talked-about education and training media. To prepare courses for online delivery and to maintain their effectiveness, the designer must have an understanding of e-learning instructional design principles. Action learning is a proven, effective management development process that has not been implemented to date as an e-learning instructional methodology. The purpose of this exploratory case study was to examine the impact of the action learning process on the effectiveness of management level web-based instruction (WBI). A leader-led, management-level course using face-to-face delivery was converted to web-based instruction where action learning was the delivery methodology. Kirkpatrick's Four Levels of Evaluation served as the evaluation tool to determine effectiveness of the intervention. It was found that, though challenging to facilitate, the action learning online method is effective and yields changes in participants' knowledge. However, contrary to expectations, online learning communities did not form.  相似文献

Children's participation remains controversial in United Kingdom schools where children and their communities rarely have opportunity to change what happens. This paper considers an original approach that developed cooperative intergenerational inquiry with a class of 10–11-year-olds in the north of England as part of complexity-informed participatory action research to consider children's participation in schools. Children and adults considered together, what schools are for, at the same time enabling children to shape spaces for participation in lesson time. The importance of recognising these spaces as dynamic intra-subjective meeting points and of intergenerational relationships for change in schools is revealed.  相似文献

Newborns (N = 83) were presented with 3 conditions, each for 160 sec: tongue protrusion (TP), mouth opening (MO), and control (CO). In TP and MO, a female model alternated between demonstrating the gesture for 20 sec and presenting a passive, motionless face for 20 sec. In CO, she presented a passive face in both the “demonstration” and “passive” intervals. The participants' eyes were more widely open in the demonstration intervals of TP and MO than in the passive intervals, indicating that they were attending to the gestures. In TP, the participants produced more TP responses than MO responses, but in MO there was no effect, undermining the neonatal imitation hypothesis.  相似文献

This paper highlights some of the needs of adolescents who have parents with a mental illness and examines the usage of bibliotherapy as a treatment modality. Eleven young adult fiction books are examined and considered for use as a bibliotherapeutic tool among the adolescent audience whose parent suffers from a mental illness.  相似文献

Case managers are among the direct service providers responsible for engaging people with severe mental illnesses. Understanding how they interpret and respond to clinically difficult situations can inform ways to intervene and reduce service disengagement. This qualitative study explored clinically difficult situations when case managers invoked the term ??sabotage??. Interviews were conducted with 21 case managers and analyzed by co-coders focusing on how case managers used the term sabotage to describe service user behavior. Themes that emerged were attributing sabotage to; fear of success, fear of attaining what you desire, avoidance of responsibility and change, and a lack of structured support. Drawing on the concepts of clinical case management and mental health recovery, we consider implications for the training and supervision of case managers and how services are structured.  相似文献

Recent research and policy advice by international development organizations have, by their own account, sought to reverse a prior neglect of conditions in agriculture and rural areas. In pursuit of this, they have developed a vision of dynamic but incremental development in rural areas, anchored in a smallholder-based and economically diversified market economy. This vision, articulated in the World Bank's 2008 World Development Report and continuing to animate research and policy advice today, presents itself as a solution to persistent poverty in the world's least developed countries. This paper adopts a historical sociological lens to use the case of Japan, in the period from the latter half of the nineteenth century to the opening decades of the twentieth, to assess how realistic this vision is. This analysis shows that the lessons of Japan's experience are chastening for this vision of rural development. The mechanisms of growth in Japan were remarkably similar to those advertised by the World Bank's vision. However, its rural economic dynamism was based on deep socioeconomic inequalities and brought improved material conditions and greater economic security to agricultural households only with excruciating slowness, if at all. Rather than demonstrating the potential of incremental, market-oriented rural development to offer a path towards widespread poverty reduction, Japan instead serves as a warning of this development model's limitations.  相似文献

In this paper we outline a class of fully parametric proportional hazards models, in which the baseline hazard is assumed to be a power transform of the time scale, corresponding to assuming that survival times follow a Weibull distribution. Such a class of models allows for the possibility of time varying hazard rates, but assumes a constant hazard ratio. We outline how Bayesian inference proceeds for such a class of models using asymptotic approximations which require only the ability to maximize the joint log posterior density. We apply these models to a clinical trial to assess the efficacy of neutron therapy compared to conventional treatment for patients with tumors of the pelvic region. In this trial there was prior information about the log hazard ratio both in terms of elicited clinical beliefs and the results of previous studies. Finally, we consider a number of extensions to this class of models, in particular the use of alternative baseline functions, and the extension to multi-state data.  相似文献
