This work analyses the potential role of nitrogen pollution technology of crop systems of Pujiang, County in Eastern China‘s Zhejiang Province, rice and vegetables are important cropping systems. We used a case study approach involving comparison of farmer practices and improved technologies. This approach allows assessing the impact of technology on pollution, is forward looking, and can yield information on the potential of on-the-shelf technology and provide opportunities for technology development. The approach particularly suits newly developed rice technologies with large potential of reducing nitrogen pollution and for future rice and vegetables technologies. The results showed that substantial reductions in nitrogen pollution are feasible for both types of crops. 相似文献

Mobile technology – such as tablets, cell phones, and wearable devices – has the potential to play a useful role in promoting academic learning. This potential motivates this special issue on “Mobile Technology, Learning, and Achievement: Advances in Understanding and Measuring the Role of Mobile Technology in Education” edited by Matthew L. Bernacki, Jeffrey Greene, and Helen Crompton. Research on learning with mobile technology should focus on three research questions: Do students learn academic content better with mobile technology than with conventional media (media comparison question)? Which instructional features afforded by mobile technology cause learning (instructional method question)? Under what conditions do students learn academic content better with mobile technology than with conventional media (boundary condition question)? A research agenda is proposed. 相似文献

This article introduces the Special Issue on Computers and Education. The papers in this special issue focus on the potential contribution of technology to education. The involvement of educational psychologists is critical for understanding how the new technology develops and shapes cognitive functioning and intelligence, and for determining how to adapt instruction to individual differences and how to create instructional settings to realize technology's potential. 相似文献

正确定位教师与技术的关系是提升信息化教学质量的关键。然而,"控制"成为当前两者关系的主题:即教师控制技术或者教师反向"控制"技术。"控制"是对教师与技术关系的误解,其遮蔽了技术的教育作用力。"共生"注重共生元素间的共存与共荣,将成为重构教师与技术关系的理想选择。提升教师的"自我"意识与并树立"人文"技术观,是教师与技术"共生"关系实现的路径。 相似文献

哈贝马斯的科学技术社会功能理论 总被引：1，自引：0，他引：1
哈贝马斯论述了科学经过技术物化为物质形态,从而实现由潜在的生产力转化为直接的生产力。科学技术成为第一生产力并执行意识形态职能,虽维护了资本主义的社会现状,但他没意识到在广度和深度上加深其基本矛盾,推进其灭亡过程的一面,没意识到科学技术还有推进社会政治民主化过程的一面,没意识到科学技术还有与人的全面发展紧密相联系的一面。 相似文献

The subject of this article is the use of augmented reality technology in library and information science education. The aim is to determine the scope and potential uses of augmented reality in the education of information professionals. In order to determine the scope and forms of potential use of AR technology in LIS education a two-step analysis was conducted. The first stage was the in-depth analysis of LIS training programs offered by academic centers in Poland, including 8 programs (4 bachelor degree and 4 master degree). In this way, more than 350 learning outcomes were analyzed and grouped according to the frequency of occurrence. During the second stage of the study a list of the most important learning outcomes was compared with a list of skill areas that AR technology helps to develop, in order to formulate conclusions according to the potential use of AR in LIS education. Summarizing the results of the study, it can be concluded that AR technology is a useful teaching tool which enables students to achieve improved learning outcomes in the practical skills needed by librarians, as well as the personal and social competencies relevant to labor market needs. 相似文献

This study examined the attitudes of nine teachers in a two-way dual-language program in regard to using technology to support the linguistic and academic development of emergent bilinguals. Using a phenomenological, multiple case-study approach, teachers' perceptions about using technology in education and the potential of technology to advance the students' bilingualism and biliteracy were analyzed. Results showed that teachers had a positive outlook about the potential of technology as a tool to support the academic and linguistic growth of the students. However, several significant challenges were identified, most notably among them the scarcity of technological hardware at the school and the shortage of Spanish-language educational resources. The teachers' perception was that a greater availability of digital technologies, including resources in the Spanish language, would greatly enhance student learning. 相似文献

Historically implementing, maintaining and managing educational technology has been difficult for K-12 educational systems. Consequently, opportunities for significant advances in K-12 education have often gone unrealized. With the maturation of Internet delivered services along with K-12 institutional trends, educational technologies are poised to help support the transformation K-12 education by providing student access to educational resources on an anywhere, anytime, any device basis. In addition, an emerging body of empirical research shows that when implemented systematically, technology can support a wide range of potential education innovations including inverted classrooms, peer-to-peer teaching and customized learning as well as increased academic achievement.A major public policy question is how best to insure educational technology resources reach all K-12 students in the shortest time and most equitable way possible. In response, this paper adopted an educational technology value chain model to assess potential avenues and barriers to implementing educational technology inK-12 systems. We find that a fully implemented educational technology value chain would directly benefit students, teachers, school systems and society. However, the analysis also finds that efforts to implement educational technology in K-12 systems still must overcome challenges and risks. 相似文献

The discussion paper released by the Review of Higher Education Financing and Policy (West Review) touches on some important issues for Australian higher education, notably the status and quality of teaching and the potential effect of information technology. However, its weaknesses lie in a failure to address the interrelationship between research and teaching; a simplistic view of the potential for information technology to drive down costs; and little consideration of ways in which the university sector is coping with change. 相似文献

Because technology in the home is becoming ever more available, understanding the role of technology in early childhood development is increasingly an opportunity and a concern for educators. This report examines data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99, to provide an overview of the role of technology in the home and its impact on reading and math achievement in the early grades. The results show that access and use of technology influence children's academic achievement. Although the results show that having access to technology can contribute significantly to the achievement of young children, mere access is unlikely to be sufficient for all young children to benefit from technology in the home. Adults will need to mediate the use of these potential learning tools for children. Based on the findings of this report, policymakers should support increasing the availability of computers for low-income families and continue to discourage extensive viewing of TV, and researchers should focus on the specific methods that parents can enact to realize the learning potential of an increasingly ubiquitous resource: computers and the Internet in the home. 相似文献
