Impact of commercial search engines and international databases on engineering teaching and research
Professor Hubert Chanson 《European Journal of Engineering Education》2007,32(3):261-269
For the last three decades, the engineering higher education and professional environments have been completely transformed by the ‘electronic/digital information revolution’ that has included the introduction of personal computer, the development of email and world wide web, and broadband Internet connections at home. Herein the writer compares the performances of several digital tools with traditional library resources. While new specialised search engines and open access digital repositories may fill a gap between conventional search engines and traditional references, these should be not be confused with real libraries and international scientific databases that encompass textbooks and peer-reviewed scholarly works. An absence of listing in some Internet search listings, databases and repositories is not an indication of standing. Researchers, engineers and academics should remember these key differences in assessing the quality of bibliographic ‘research’ based solely upon Internet searches. 相似文献

Parents whose children are diagnosed in an infant screening program are required to make some difficult choices about the management of the hearing loss at a time when they are emotionally vulnerable. They are required to evaluate information and outcomes regarding issues such as technology for hearing impairment, communication options, education, and rehabilitation. The World Wide Web has become an important resource of health information for both health consumers and practitioners. The ability to obtain accurate health information online quickly, conveniently, and privately provides opportunity to make informed decisions. However, little is known about the level of the use of the Internet to acquire health information, particularly in the case of parents of deaf children seeking information. This study confirms that searches for health information on the Internet are conducted primarily by mothers. In the Australian context, there is minimal online information available to families beyond early intervention. Information on education issues, mental health, and deafness or the day-to-day management of a child or adolescent with a hearing loss are neglected topics on Web sites. This study also revealed that the majority of respondents had never visited HealthInsite or Medline Plus, two gateway sites for reliable consumer health information, although the information on these sites is more generic in nature and unlikely to assist parents to make informed choices on complex issues such as communication options or education. However, the study suggested that half the parents have talked to their doctor or hearing professional about information they found on the Internet, which is an encouraging tendency. 相似文献

This article offers a critique of Michael Young’s perspective on the Internet as it relates to the knowledge-driven curriculum he supports. I argue that the Internet is a site of both theoretical knowledge and everyday concepts which challenges the differentiation of knowledge that premises much of Young’s writing. Google searches from the perspective of a student and teacher show that theoretical knowledge with vertical links to subject and disciplinary communities as well as coherence built through links between concepts is fairly readily accessed on the Internet. The importance of information literacy for students, the critical need to curate content on the web, as well as the implications for the curriculum of framing ‘knowing’ as encompassing ‘being familiar’ and comprehending’ are highlighted. 相似文献

College students use technology to gather information and conduct their daily lives. Textbooks increasingly relate course content to students through technology. An analysis of the top ten public speaking textbooks revealed the ways in which technology is addressed within information-gathering chapters. Seven areas of technology were identified: search engines/conducting searches, the Internet, general computing, non-computer technologies, technology applications, technology in general, and the provision of Website addresses. Chi-square tests showed significant differences in the coverage of the technology topics. Instructors can make more informed textbook selections as a result of this investigation. Technology is essential to the information gathering process, and this study suggests how its treatment may be more beneficial to both students and instructors. 相似文献

The Internet is a powerful resource for research providing limitless access to information. This article considers an application in the undergraduate Bachelor of Education in Design and Technology course (B. Ed. [Hons] D&T ).
This four year course prepares students for the teaching of Design and Technology in secondary schools, focusing on the development of skills in design and problem solving. A project based approach is used within the course to encourage individual research activity and promote a student centred learning experience. As well as books and video resources, the students have access to the Internet through a network of Windows NT workstations. The potential for exploration via the Internet has been readily exploited by students and this article reviews the use made of this facility by students and their impressions of its value
Providing Internet access posed many technical and managerial challenges, some of which are considered in the article. The experience gained in its use has provided some interesting insights into other issues surrounding Internet access.
Student response to the Internet as a tool, experience of searches and some of their concerns about their experience in accessing Internet along with the perceived benefits are discussed in the article 相似文献

We live at a time when the Internet is used increasingly for communication, for information, and for the exchange of goods and services. Questions arise about how people with learning disabilities make use of this new technology. In this article, Bjorn Harrysson, with two of his colleagues, A. Svensk and G. I. Johansson, from the Department of Design Sciences at the Lund Institute of Technology in Sweden, explores the opportunities and difficulties experienced by members of this group when navigating the Internet.
Harrysson, Svensk and Johansson observed seven people, aged between 15 and 44 and with mild to moderate developmental disabilities, as they navigated between different web pages using the general tools of Microsoft Internet Explorer Web Browser. The authors describe some of the strategies that were used for moving within and between web pages and for opening web pages, carrying out searches and finding preferred web sites.
The results of the study are partly optimistic. The people involved made good use of many of the features of the general software. They experienced greater difficulties when it became necessary to use text to navigate and explore the huge potential of the Internet. Harrysson, Svensk and Johansson close their article by making a series of recommendations for developments that would facilitate ease of access and independence in the use of the Internet for people with developmental disabilities. 相似文献
