Millions of Canadians residing in Canada's northern, isolated, rural, and remote communities do not have broadband Internet access. This situation has led to a national “broadband divide.” That is, the deployment of wireline broadband is very limited in Canada's northern, isolated, rural, and remote areas because of the significant expense of installation and maintenance of the wired infrastructure needed to reach dwellings in these locations.Terrestrial broadband wireless technology, on the other hand, does not entail the same kind of physical infrastructure. As a result, there are dramatic changes in how spatial considerations affect the provision of broadband Internet services (BIS) to areas beyond the urban zone. In particular, the spatial question is now focused on assessing the capacity for different technological solutions to reach profitable population bases, and brings to the forefront organizations that are developing non-line-of-sight (NLOS) technologies that would permit wireless Internet access over much greater distances than current solutions.We begin this paper by establishing the importance of broadband connectivity to Canada's northern, isolated, rural, and remote communities. This discussion comments on the role of the Government of Canada in the provision of broadband connectivity to residents of these communities, and outlines the current regulatory issues that govern wireless services and policy formulation.The second part of the paper illustrates the use of geographic information system (GIS) approaches in the study of wireless broadband planning and deployment. Case study findings suggest that GIS applications can make a significant contribution to the analysis of wireless deployment planning, to the understanding of the relationships between wireless signal sources and consumers, and to the spatial configuration of terrestrial wireless broadband networks. We conclude the paper by discussing how the GIS approach employed could be used to inform the public policy process with regard to increasing access to broadband Internet services in all regions of the country, and thereby providing the opportunity for all Canadians, regardless of location, to fully participate in the Information Society. 相似文献

Questionnaires are important tools for assessing attitudes regarding conservation issues. However, they are not easily comparable and their reliability has been insufficiently assessed. We examined factors influencing responses to open- and closed-ended questions about animal conservation to more than 600 schoolchildren (9 years old on average). We analysed the level of understanding, controllable (e.g. sample size) and less controllable factors (e.g. affectivity). Most children responded appropriately to the questions, but subtle changes in the phrasing influenced the answers. Affectivity towards endearing species and spontaneity also influenced the responses whereas small sample sizes (～50 children) provided relatively stable patterns. Overall, we suggest that standardization of questionnaires administered over large spatial and time scales is needed to accurately assess children's attitudes towards conservation issues. 相似文献

The purpose of the current study was to investigate the role of internal factors (e.g. attitudes towards computers and internet, self-confidence, and knowledge) and external factors (perceived support) on the level of information and communication technology (ICT) usage. The participants were 1898 pre-service teachers in Turkey. The results revealed that Turkey, like many other developing countries in the world, is in the early phase of ICT integration in education. Most pre-service teachers reported that they use only basic ICT applications for educational purposes. Internal and external factors were found to be related to each other and to ICT usage level. In general, male pre-service teachers’ knowledge and usage levels of ICT were higher than that of female teachers. 相似文献

Feedback has been one of the important elements of learning and teaching theories and still pervades the literature and instructional models, especially computer and web-based ones. However, the mechanisms about feedback dominating the fundamentals of all the instructional models designed for self-learning have changed considerably with the interactive multimedia technology of today, which have recourse to a wider range of potential in terms of use and functionality. The study intends to indicate that feedback has double functions： On one hand, it has classic ＂triad＂ functions--feedback as motivator, reinforcement and information--in terms of computer-assisted instruction and, on the other hand, as it is emphasized in this study, it forms the core and maintains the continuity of the machine-learner interaction in multimedia software designed today. This work, originally a discussion paper, consists of a review of the related literature and analyses of the software programs designed for teaching French to adults as foreign language in French module of Multimedia Language Learning Centre at Charles-de-Gaulle University （Lille-France）. 相似文献

The purpose of this study is to assess students’ conceptual learning of electricity and magnetism and examine how these conceptions,
beliefs about physics, and quantitative problem-solving skills would change after peer instruction (PI). The Conceptual Survey
of Electricity and Magnetism (CSEM), Colorado Learning Attitudes about Science Survey (CLASS), multiple-choice test was administered
as a pre- and posttest with Solomon 4 group design to students (N = 138) enrolled on freshman level physics course. The number of chapter taught to the students was 14. Problem-solving
strategy steps were asked to students in the exam. The analyses of CSEM showed that the treatment group (g = 0.62) obtained significantly higher conceptual learning gain than the control group (g = 0.36). The conceptual understanding and problem-solving skills of the students on magnetism considerably enhanced when
PI was conducted (37% and 20%, respectively). CLASS results for 5 subscales (conceptual understanding, applied conceptual
understanding, problem solving general, problem solving confidence, and problem solving sophistication) supported the findings
of CSEM. 相似文献

The aim of this 2-group study was to investigate the following question: Are there significant differences between scaffolded design-based learning controlled using 7 forms and teacher-directed instruction methods for the toy crane project on grade 7 students’ posttest scores on the simple machines achievement test, attitude toward simple machines, and attitude toward creativity in simple machines after adjusting for their respective pretest scores and the prior semester science grades? The study group (N = 65) consisted of grade 7 students in public middle schools in Burdur, Turkey. There were significant treatment effects favoring the first method with large effect sizes on both achievement and creative attitude scores. Teaching topics about simple machines with the design-based method increased students’ achievement and creative attitude without disadvantaging their attitude toward the topic as they constructed new knowledge through each step of the precise process. 相似文献

This research investigated the impact of teacher questions, question types, and interaction patterns that coincide with high and low levels of constructivist teaching practices. Through both quantitative and qualitative methods the findings revealed that teachers facilitating classrooms with high levels of constructivist teaching practices (HLCTP) were very active as they asked a significantly greater number of questions compared to teachers facilitating classrooms with low levels of constructivists teaching practices (LLCTP). In addition, teachers facilitating with HLCTP used a significantly greater number of open‐ended questions when compared with other types of questions (closed‐ended questions and task‐oriented questions). Closed‐ended questions were found in the HLCTP classrooms as teachers were concerned with focusing students on completing investigations, but open‐ended questions were more often found with the aim of promoting student actions attuned to knowledge construction. 相似文献

The purpose of this nationwide survey was to assess young Turkish pupils’ environmental literacy (EL) level by considering six EL components. The sample of the study comprised of 2,412 fifth graders selected from 78 elementary schools (26 private and 52 public) in 26 provinces of Turkey. Data were obtained through the use of an elementary school environmental literacy instrument (ESELI) including five parts and total of 75 items. The results revealed that the composite EL score of the students was found to be 149.66 (SD = 26.19), suggesting a moderate level of EL among 61% percent of the students (n = 1,545). On the other hand, more than a quarter of the participants (27.3%, n = 659) held high level EL, whereas only 22 students (0.9%) showed low level EL. The implications of the results to policy, practice, and further research were discussed at the end of the study. 相似文献
