This study aims to ascertain student and staff attitudes to and perceptions of audio feedback made available via the virtual learning environment (VLE) for summative assessment. Consistent with action research and reflective practice, this study identifies best practice, highlighting issues in relation to implementation with the intention of redesigning activities in the light of the findings. It utilises four case studies where audio feedback was provided to students using the Wimba voice authoring tool within Blackboard Learn+ for various types of summative assessment. The intention was to identify how and in what context audio feedback via the VLE is effective and why. The research was undertaken via a combination of techniques, including a student survey and staff reflective logs. The findings indicate that students liked the convenience, effectiveness, flexibility and personalised nature of this feedback, but raised concerns with some aspects of the technology. This paper also makes practical recommendations for the use of the feedback mechanism, focusing on the most effective use of the digital medium, and highlights directions for future research.  相似文献

Due to the Covid-19 pandemic, many academic institutions had to rapidly transition education to a remote online environment. While a hurdle for most educators, this transition posed an even greater challenge for anatomy educators, many of whom were forced to depart from the traditional cadaver-based laboratory to a virtual format. Recent publications have discussed the rapid transition to online formats necessitated by Covid-19 and the accompanying difficulties, but none have identified specific factors that influenced the difficulty of this transition. Anatomy educators were surveyed to examine how this transition was accomplished and perceived. Of the 165 educators who responded, the majority utilized cadaver-based laboratory instruction. Educators felt that transitioning the laboratory portion of their courses was significantly more difficult and required more time than converting lecture materials. Factors that impacted the difficulty of the transition included a number of pedagogical aspects of the pre-Covid-19 curricula, including the delivery format of prior content, availability of pre-existing electronic materials, and the laboratory technique previously used. Additionally, the length of time an educator had been teaching prior to Covid-19 impacted their perception of difficulty, with newer and more senior educators finding this much more challenging than mid-tenure educators. Ease of transition may be related to previous exposure to curricular reform, experience with multiple anatomy pedagogies, and educator adaptability. While not surprising that converting a cadaver-based laboratory to an online format was challenging, knowledge of the alignment of this difficulty with prior educator pedagogy can help guide future innovations to anatomy education.  相似文献

Government-led interorganizational alliance networks present a sensible opportunity to overcome many societal challenges through collaborative governance. In particular, few researchers have studied alliance networks in the field of energy conservation in commercial buildings—a sector with unique barriers to greater diffusion of innovative cost-saving strategies. We applied an analytic inductive case-based method and social network analysis to study one particular alliance network: the United States Commercial Building Energy Alliances representing interests from retail, commercial real estate, and healthcare sectors. This alliance network was initiated by the United States Department of Energy, with assistance from several federally funded research laboratories in the United States, to promote the diffusion of knowledge and ultimately encourage greater deployment of energy efficiency and clean energy strategies in commercial buildings. We draw upon interview data from 28 cases of private, non-profit, and governmental organizations and complete network data from the alliance participants. We honed in on eight focal cases of governmental organizations to provide insight on how the four forms of energy and environmental data, information, and knowledge shared within an alliance network address the challenge of a vastly underutilized energy resource, namely conservation. Further, we identify and discuss the public's four roles—Commissioner, Interpreter, Marketer, and User—in providing balance to the diffusion of both private and public goods in a network.  相似文献

大学的扩招进一步导致教育资源的稀缺,最受影响的当属实验与实践教学环节的减弱。水电站建筑物作为水利工程专业的核心课程之一,具有内容多、知识面广、实践性强的特点,是一门老师授课难、学生学习痛苦的课程。若无较好的实验环节支持,学生的学习将变得空洞、无趣甚至不知所以。文章以三峡大学水电站建筑物的课程实验为例,介绍了该课程相关实验室的建设。实验室初步建成后,对教学效果有较明显的提升。  相似文献
