美国优质网络课程的案例介绍   总被引:1,自引:0,他引:1  
近十年来,我国高校网络课程建设成果显著,但其中暴露出的理论与实践相脱离的现象也比较严重。通过介绍美国德克萨斯A&M大学Dooley教授开设的网络课程《远程教育的高级方法》,尝试剖析其作为优质网络课程在管理平台、教学设计、交互安排、评价方法以及支持服务等方面所具有的特征,以期与国内远程教育的研究者和实践者分享经验。  相似文献

Do you regularly reflect on the value you bring to your client? The act of reflection is something experienced consultants, both internal and external, consistently do in their practice. This article examines the ways in which Certified Performance Technologists (CPTs) define and recognize the success of their efforts, but most importantly, how they learn from engagements that do not always end with the desired outcome. You will hear from CPTs across several industries in their own words about what strategies they have employed to continue to improve their skill sets.  相似文献

This case study examines the design practices of instructional design (ID) students while working on a realistic design project (Joel, 1987) to explore whether ID students make design judgments; how, when, and where they are making them; and what kinds of judgments they make during a realistic instructional design process. The perspective taken in this study is that design judgments comprise multiple, complex types and are not confined to moments of overt decision making (Nelson & Stolterman, 2012). In this small‐scale case study, a group of students was observed in the process of designing instruction within a semester. The findings of the study suggest that these ID students continuously made design judgments of many kinds throughout the design process.  相似文献

Droplet microfluidics enables powerful analytic capabilities but often requires workflows involving macro- and microfluidic processing steps that are cumbersome to perform manually. Here, we demonstrate the automation of droplet microfluidics with commercial fluid-handling robotics. The workflows incorporate common microfluidic devices including droplet generators, mergers, and sorters and utilize the robot''s native capabilities for thermal control, incubation, and plate scanning. The ability to automate microfluidic devices using commercial fluid handling will speed up the integration of these methods into biological workflows.  相似文献

This study aims to reconsider and re-evaluate the rapid circulation of global creative city policy from the viewpoint of its creative workforce by focusing on the case of Yokohama, Japan. To shed light on this workforce’s everyday experiences and labor subjectivity, this investigation draws ideas from recent research trends of “creative labor” from the field of media and cultural studies, sociology of work, and political economy of communication. Based on in-depth interviews and participant observations, this research focuses on how the ethical and moral dimensions of labor subjectivity in creative work are prominently important in explaining Yokohama workers’ everyday living and working experiences as creative labor. Unexpectedly, this study found that these moral and ethical sentiments and actions, which take on the role of retaining their labor motivation, actually limit the development of political subjects who can resist given precarious working conditions and thereby hinder them from building a collective solidarity as “workers.” Thus this investigation concludes that the creative worker’s subjectivity retreats to solely a moral dimension rather than to a political one. Through this finding, this study explores whether the articulation of moral-political and social values in the course of cultural work can evolve from creative workers’ moral and ethical sensitivities and actions.  相似文献

The purpose of this study was to investigate kinematic and spatiotemporal variables of aquatic treadmill walking at three different water depths. A total of 15 healthy individuals completed three two-minute walking trials at three different water depths. The aquatic treadmill walking was conducted at waist-depth, chest-depth and neck-depth, while a customised 3-D underwater motion analysis system captured their walking. Each participant’s self-selected walking speed at the waist level was used as a reference speed, which was applied to the remaining two test conditions. A repeated measures ANOVA showed statistically significant differences among the three walking conditions in stride length, cadence, peak hip extension, hip range of motion (ROM), peak ankle plantar flexion and ankle ROM (All p values < 0.05). The participants walked with increased stride length and decreased cadence during neck level as compared to waist and chest level. They also showed increased ankle ROM and decreased hip ROM as the water depth rose from waist and chest to the neck level. However, our study found no significant difference between waist and chest level water in all variables. Hydrodynamics, such as buoyancy and drag force, in response to changes in water depths, can affect gait patterns during aquatic treadmill walking.  相似文献

This study attempts to answer two questions. First, can a single cultural event impact the stock prices of a wide range of companies and sectors? Second, was the positive stock market response in the information technology (IT) sector as well as performing arts sector significant? To answer these questions, we examine whether a hit pop single, “Gangnam Style” by Park Jae-Sang in 2012, affected related sectors of the Korean stock market and whether market reactions went beyond the stock price of the singer’s agency to affect those of other firms. We use an event study approach. The results show two notable empirical findings. First, although the findings indicating abnormal returns and cumulative abnormal returns appear mixed, the overall results imply that the unprecedented worldwide hit single by the South Korean singer positively affected the Recreation & Culture and Digital Content sectors. In other words, the market interpreted the event as good news, with shareholders expecting positive effects on the related sectors. Second, a positive stock market response was observed in the IT sector as well.  相似文献
