Abstract The following paper should be seen as an addition to that provided in the Proceedings of the 7th ICTE.’ For reasons of brevity, it does not deal to any large extent with the background to the project, but details the progress of a study into the effects of introducing laptops into primary (elementary) school. The project has provided every pupil in one class with a laptop computer and has tracked the use being made of it as a curriculum tool for writing. The second phase of the project is under way, with a completion date of April 1991. 相似文献

Abstract Past experience with an industrial, classroom‐based educational model for aboriginal students has revealed severe limitations that have resulted in secondary graduation levels far below those of the Canadian population in general. Distance education has the potential to redress many of the traditional model's inherent weaknesses, including the reduction of problems associated with cultural assimilation. Distance education also has the potential to enhance the multimedia resources of band‐controlled schools, schools that have shown good promise in raising retention and attainment rates. This article reviews the current situation pertaining to education in Canadian aboriginal communities, discusses the strengths and weaknesses of two distance education programs for aboriginals, and concludes with key guidelines for future distance education endeavors. 相似文献

Urban information integration for advanced e-Planning in Europe 总被引:1,自引:0,他引:1
Hongxia Wang Yonghui Song Andy Hamilton Steve Curwell 《Government Information Quarterly》2007,24(4):736
Urban planning is a complex task requiring multidimensional urban information (spatial, social, economic, etc.). The need for assistance in performing urban planning tasks has led to the rapid development of urban information systems, especially “e-Planning” systems, with the support of government policy and emerging information and communication technologies (ICT). In order to enhance the capability of e-Planning and to facilitate 3D visualization and rich analysis of complex city problems, it is very important to allow information from the various sources to be shared and integrated. This paper focuses on technical approaches for multidimensional information integration, especially spatial information integration. In particular it describes the Building Data Integration System (BDIS), developed as part of the IntelCities project, which demonstrates the type of multidimensional systems that are likely to be used in future urban information systems. Functionally, the BDIS demonstrates the feasibility of systems to support the multinational collaboration of construction professionals in the procurement and renovation of buildings. For such systems to be accepted in the United Kingdom (UK) and Europe, they need to be developed with regard to current planning information structures and standards in the UK and Europe which are reviewed in this paper. The achievements and further development of multidimensional information integration through the use of innovative urban data modelling techniques are discussed. 相似文献

There is a widespread view held by health clinicians that their work effectiveness is impaired by 'information overload.' Building upon a previous work by Wilson, a review of the literature was undertaken to look for the evidence of this. It was found that the literature, particularly in the context of the clinical environment, was limited. This review explores the diverse overarching theories of information overload, effects of the phenomenon that are perceived to occur and proposed solutions to this problem. Many of the papers noted an information explosion but only three authors explicitly attempted to measure both the quantity and the complexity of this information. It was also found that the typology of the information studied was severely limited with most studies exploring information such as guidelines, access to journals, research findings and other knowledge intensive areas. Solutions proposed seem to concentrate on technological means rather than exploring the use of humans either in management of information or as a step in the filtering process. 相似文献

The purpose of this study was to develop a submaximal, 1.5-mile endurance test for college-aged students using walking, jogging, or running exercise. College students (N = 101: 52 men, 47 women), ages 18-26years, successfully completed the 1.5-mile test twice, and a maximal graded exercise test. Participants were instructed to achieve a "somewhat hard" exercise intensity (rating of perceived exertion = 13) and maintain a steady pace throughout each 1.5-mile test. Multiple linear regression generated the following prediction equation: VO2 max = 65.404 + 7.707 x gender (1 = male; 0 =female) - 0.159 x body mass (kg) - 0.843 x elapsed exercise time (min; walking, jogging orrunning). This equation shows acceptable validity (R = .86, SEE = 3.37 ml x kg(-1) min(-1)) similar to the accuracy of comparable field tests, and reliability (ICC = .93) is also comparable to similar models. The statistical shrinkage is minimal (R(press) = 0.85, SEE(press) = 3.51 ml x kg(-) x min(-1)); hence, it should provide comparable results when applied to other similar samples. A regression model (R =.90, and SEE = 2.87 ml x kg(-1) min(-1)) including exercise heart rate was also developed: VO2 max = 100.162 +/- 7.301 x gender(1 = male; 0 =female) - 0.164 x body mass (kg) - 1.273 x elapsed exercise time -0.156 x exercise heart rate, for those who have access to electronic heart rate monitors. This submaximal 1.5-mile test accurately predicts maximal oxygen uptake (VO2max) without measuring heart rate and is similar to the 1.5-mile run in that it allowsfor mass testing and requires only a flat, measured distance and a stopwatch. Further, it can accommodate a wide range of fitness levels (from walkers to runners). 相似文献
