This paper reports on a case study of an online pre-service teacher education course in a New Zealand university aimed at exploring the potential of student-generated podcasts as a form of interactive formative assessment at a distance. The study was part of a wider two-year funded project with the overall goal of documenting, developing, and disseminating effective and innovative e-learning practice. Findings from lecturer and tutor interviews, student focus group (FG) discussion, and course evaluations indicate that the podcasting task provided opportunities for the course lecturer, tutors, and students to learn and share ideas with one another. The experience empowered students to develop the skills and confidence to initiate more independent inquiry into technologies to support their pedagogical purposes. The study contributes to a better understanding of the skills, dispositions, and knowledge needed to prepare teacher candidates for teaching-learning contexts where information and communication technologies are increasingly pivotal.  相似文献

Failure has an important role to play in learning how to navigate highly uncertain organizational environments. But “failing fast” just for its own sake may in fact undermine learning if not set up or handled correctly. Using failure-based pedagogy, including generative failure, whole-person learning, and entrepreneurial thinking, an MBA course was designed and experienced by 48 students in three instances. Structured around a novel guiding framework of “brains, bravery, and belief,” the course has resulted in highly impactful learning for students. Student experiments are typically based around either exploring an entrepreneurial idea, developing or enhancing a particular skill, or applying skills and knowledge to help improve a societal problem. In each case, students are supported but also challenged to go beyond their comfort zones and encounter some intelligent failure in the journey. Regular reflection on their experiences, both from a cognitive and an affective perspective, is an essential element built into the course experience. The course, which itself was an experiment and not without its own instructive failures, is now an essential part of the MBA experience.  相似文献

Emergence of new industries from evolving technologies is critical to the global economy, yet has been relatively understudied due to the paucity of available data. This study draws lessons on industry emergence, by analyzing how a solid-state lighting (SSL) industry grew out of light emitting diode (LED) technologies that evolved for half a century, with participation by tens of thousands of researchers in universities, national laboratories, and firms. Using data on publications, patents, and firms combined with business history we trace the evolution of SSL through a succession of market niches. At times a few researchers with unorthodox research approaches made breakthroughs that greatly advanced particular technology trajectories and pushed LED research in unexpected directions. A succession of LED market niches advanced the technology and provided profits to incentivize continuing research while reducing cost and improving efficacy of LEDs. Innovating firms developed a thicket of patents and captured substantial profit, but were embroiled in extensive litigation that was ultimately resolved through cross-licensing. A major new generation of lighting products is now disrupting the traditional lighting industry. Although the leading incumbent lighting firms all invested early and heavily in SSL, the industry's future leadership is uncertain.  相似文献

Basing treatment, policy and planning decisions on the best available research knowledge remains a central principle in modern health care around the world, yet many health professionals find acquiring and managing published research knowledge challenging. In this paper, we report on a Soft Systems Methodology-based collaborative action research initiative with a specialist mental health service from the United Kingdom's National Health Service. Our objective was to design and implement improvements to their knowledge acquisition and management activities in order to facilitate sustained and effective evidence-based practices. We report on both the factors found to impede effective research knowledge acquisition and management and the development of more integrated knowledge management processes designed to improve the situation.  相似文献

The education of children with behavioural difficulties is under scrutiny from various quarters. The provision of specialised school environments isbeing questioned and, at the same time, there is pressure to minimise the exclusion of disruptive pupils. The study reported in this article lookedat a group of children whose behaviour had prompted placement in a school for emotionally and behaviourally disordered (EBD) pupils. The results showed the overall rate of psychiatric disturbance in the group was 86% and, in particular, that the rate of Attention Deficit Hyperactivity Disorder (ADHD) was 70%. These findings suggest that a significant minority of disruptive pupils may have their difficulties compounded by the presence of ADHD, and raises the question of whether specific screening processes should be established for such pupils.  相似文献

A very rich collection of archival material is used to compare two anticancer drugs commercialised by multinationals collaborating with public sector research, one in the USA and one in France. The framework of national innovation systems is used to compare the innovative environments for each development (different institutional structures, research programmes, financing, industry-academic-government relationships, environmental concern, and intellectual property regimes). The empirical work was able to bring out the nuances and subtleties of each environment, the way in which innovation took place in practice, and some striking differences from what stereotypical accounts of innovation in each country would have suggested.  相似文献
