目前缺乏从技术转移本质与特征理论视角研究技术转移发展对策,为此,系统分析技术转移的驱动因素、运动机理、构成要素与过程等4个本质维度,以及利益性、势差性和重复性等3个特征维度,比较研究美国、日本和韩国的技术转移发展实践。研究显示,美日韩政府在技术转移过程中起引导作用,通过制定和实施相关法案、法律和计划等,保护有关参与者利益,制约技术转移的无限制重复;长期稳定的较高水平R&D投入产生大量可供转移转化的技术成果,并在国家宏观层面整合的科研机构的共同作用下形成技术转移势差;通过建立区域技术转移中心、大学专利技术转移组织、技术创新中心和技术商业孵化器等形式的技术转移机构,促进技术转移多主体联合,驱动技术转移运动。最后借鉴发达国家经验,构建技术转移逻辑框架,提出加强政府引导与制度创新等推动中国技术转移的对策建议。 相似文献

Internet‐based science learning has been advocated by many science educators for more than a decade. This review examines relevant research on this topic. Sixty‐five papers are included in the review. The review consists of the following two major categories: (1) the role of demographics and learners' characteristics in Internet‐based science learning, such as demographic background, prior knowledge, and self‐efficacy; and (2) the learning outcomes derived from Internet‐based science learning, such as attitude, motivation, conceptual understanding, and conceptual change. Some important conclusions are drawn from the review. For example, Internet‐based science learning is equally favorable, or in some cases more so, to learning for female students compared to male students. The learner's control is essential for enhancing students' attitudes and motivation toward learning in Internet‐based science learning environments. Nevertheless, appropriate guidance from teachers, moderators, or the Internet‐based learning environment itself is still quite crucial in Internet‐based science learning. Recommendations for future research related to the effects of Internet‐based science learning on students' metacognitive reflections, epistemological development, and worldviews are suggested. 相似文献

In an effort to establish a baseline of technology competency among our entering education students, our College of Education began implementing the Assessment of Technology Competencies (ATC) in Fall 2003. This performance-based assessment evaluates word-processing, presentation, spreadsheet, graphic/drawing, and Internet skills. Although students are not required to pass the ATC, failure impacts their final grade in an Introduction to Education course. This paper explores the impact this assessment has had on the students' use and development of technology in subsequent courses. Student perceptions of the ATC and its impact were elicited through a self-reported survey administered in a junior-level education course. Results indicate that the ATC has facilitated technology use among the participants. Respondents also revealed that their high school experiences with technology adequately prepared them for passing the ATC, despite the fact that most students are unable to pass the ATC in the first attempt. 相似文献

Technological advancements in the workplace frequently have produced contradictory effects by facilitating accessibility and efficiency while increasing interruptions and unpredictability. We combine insights from organizational paradoxes and the job demands–resources model to construct a framework identifying positive and negative mechanisms in the relationship between communication technology use (CTU) and employee well-being, operationalized as work engagement and burnout. In this study of Dutch workers, we demonstrate that CTU increases well-being through positive pathways (accessibility and efficiency) and decreases well-being through negative pathways (interruptions and unpredictability). We highlight the importance of (1) investigating CTU resources and demands simultaneously to grasp the relationship between CTU and employee well-being, and (2) considering CTU's downsides to successfully implement new communication technologies and flexible work designs. 相似文献

We present the process our institution used to create a statistics requirement for almost all incoming first‐year students. From conception and planning, to hiring and acceptance by the university community, we offer lessons learned should you consider making such a shift in your own curriculum. 相似文献
