Abstract

This research note presents a conceptual model for understanding how students embrace technology, briefly presents results of a pilot study supporting this conceptualization, and makes suggestions for web-assisted teaching and research. The conceptual framework helps the reader understand how instructors' “Marketing strategies” may need to change over the course of the semester to generate maximum acceptance of, and satisfaction with, high-tech classrooms. The conceptual framework is illustrated with data collected during a pilot study involving two web-assisted graduate foundation research courses at the Kent School of Social Work, University of Louisville. Students enrolled for two web-assisted research courses without knowing that web-assisted technology would be used in the course. The students' attitudes towards computers, their ability to access computers, as well as their skill levels in using computers were assessed. Suggestions and challenges for web-assisted teaching and research are provided based on the conceptual framework and results from the pilot study.  相似文献

提出了实数插值并行算法:采用一种高效优化的1-D插值替代经典公式插值,实现2-D插值,使得运算简便迅速,其计算模式类似于"流水"运行,不需要数据记录和数据暂存设施;而且插值运算时间的复杂性同插值单元因子的复杂性互不相关;每个插值计算周期持续时间相当于执行一个相应的加法运算和乘法运算时间;这为实现高速计算、存储共享的并行处理硬件设施提供了设计依据。  相似文献

地学中海量数据的并行可视化研究进展   总被引:2,自引:0,他引:2  
地球科学中观测和数值模拟结果数据爆炸式的增长,给可视化和分析这些海量数据带来了极大的挑战,将海量数据并行可视化技术应用到地球科学中是解决这一问题的有效手段。地球科学中海量数据可视化是目前国际科学可视化研究的一个新方向。本文首先介绍海量数据并行可视化的几个步骤,然后总结了地球科学中海量数据的特点,重点讨论了海量数据并行可视化在地幔对流、地震波传播以及海啸数值模拟等可视化研究中的应用实例。  相似文献

This article looks at the consequences of the 1991 amendment to the Australian Copyright Act, which meant that, for the copyright owner or authorised distributor to attain the right to control imports, it had to make the book available in Australia within 30 days of first publication overseas; and, to retain that right, it had to notify the retailer within 7 days of receiving an order whether it could be fulfilled within 90 days, and then in fact do so (. Accessed 28 June 2008). The article discusses the background to that change, what has happened since and what arguments are marshalled by those in favour of the status quo (restrictions that must be qualified for), and those in favour of a completely open market. The arguments used say much about the current preoccupations of those in Australian publishing. The debate around whether booksellers should be free to import copies of a new book from any supplier willing to sell them boils down to four issues: the availability in Australia of books published overseas; the price of books in Australia; the preservation of Australian publishing; and the protection of the rights of copyright holders. Those in favour of the open market believe that it would improve the first two without diminishing the latter two; those who support the status quo, that changing would bring no substantial benefits, and hurt both publishing and the rights of copyright holders. In summary, the reasons for maintaining the status quo are that things work fine as they are; that Australian literature (authors, bookshops, publishers) would suffer if things changed; and that the publisher is entitled to protect its investment through territorial control of copyright. The reasons for going to a completely open market are that only an open market can determine market price; that booksellers are unfairly disadvantaged competing against online sellers, on whom parallel importing restrictions are effectively not imposed; that copyright holders lose their rights when they sell something, and shouldn’t get a secondary chance to protect their investment; there is already a de facto open market, which unfairly restricts those who obey the law; there is a narrow window of opportunity for selling a book, which the current restrictions don’t serve; and the current situation is a poor compromise that doesn’t achieve the benefits of the open market.  相似文献

Why should computers be used in primary schools and what roles have they come to play in the classroom? This paper describes an investigation into UK primary teachers' perceptions and use of computers in the classroom. The responses collected illustrate the existence of two broad groups of teachers. Those who adopt a computer awareness perspective and those who believe that the computer should be used as a means to facilitate and enhance teaching and learning. Furthermore, the responses suggest an association between teachers' beliefs about computer use and teachers' patterns of actual computer use and thus demonstrate that educational innovations are primarily and intrinsically realized in our way of thinking before they become practice. Yet, this way of thinking may be formed not only by teachers' interpretations of official orders and requirements but also by their knowledge of information technology (IT) and their comprehension of what teaching and learning is about.  相似文献
