Over the next two decades, sub-Saharan Africa will face substantial pressure to expand its secondary education system. This is driven by the current low development of secondary education compared to other world regions, continued rapid population growth, the increase in the enrolment and completion rates at the primary education level, and the upsurge in the demand for skills. This paper suggests that in order to help countries respond to these pressures, external partners should now increase their support for secondary education, in terms of academic as well as technical and vocational skills training. Given the attributes of the African economies and the continuing need for foundation skills, this paper argues that in the current situation, particularly the lower secondary level will have to be strengthened, in many cases through a longer basic education cycle for all. The necessary rapid expansion of secondary education will require substantial investments, and this paper discusses how aid allocation can be made more evidence-based and used in a more strategic way to make these investments more effective and sustainable. While aid will continue to have a role to play over the next decade especially in fragile states, in the long run it is African countries’ capacity to achieve sustained economic growth which will be the single most important factor determining their ability to meet the financing needs. 相似文献

With the help of a couple of satellites going around the earth we can find our position on the earth with very high accuracy by measuring ranges from these satellites. The satellite based navigation system is called the GPS (global positioning system). In the first part1 we described the basic principle of the operation of GPS. This part is about the mechanism and uses of GPS. 相似文献

Since ancient times navigators have been taking the help of celestial objects to find angles between the horizontal and the lines of sight to the celestial objects, in order to determine their position on the earth. Now, they would take the help of couple of manmade objects whizzing around the earth to find their position with very high accuracy, by measuring ranges from these objects. These objects are satellites and this article gives a brief introduction to a satellite based navigation system, called the GPS (Global Positioning System) in two parts. The first part introduces the basic principle of operation of GPS. 相似文献

Because citizens continue to demand educational accountability, it is unlikely that basic skills testing in the high schools will dissipate over the next few years. However, changes will be made in testing methodology and content. Educators and citizens will debate whether to raise minimum competency requirements as students' scores increase over time. Tests will be revised to include more than just reading, writing, and arithmetic. Advances will be seen in the collection and transmission of test data through new computer technology. Statewide student data bases will be developed. High-school course testing and state-by-state achievement testing will be introduced. The worth and financial cost of mandated testing programs will continue to be discussed. 相似文献

As the 1980s approach, most colleges and universities can expect several current trends affecting education to continue. Fewer students will be attending institutions of higher education. Administrators and faculty have both begun to search for humane, but effective, methods of reducing faculty size. This paper examines the potential of early retirement programs as a means of adjusting to the needs for a steady state staffing pattern during the next decade and beyond. Even though early retirement does not seem encouraging, tentative recommendations are offered for its effective use. 相似文献

The Millennium Challenge Account (MCA) is a commitment of the United States to raise its grant aid by a factor of 50% over the next 3 years and will result in a $5 billion annual increase over current foreign aid levels. Many other countries and multinational development assistance agencies will be asked to help cofinance this new account, and their participation would augment this original proposal from the United States. The MCA offers the opportunity for a quantum change in the prospects for peace, stability, and the alleviation of poverty. However, will it work? This article suggests that the MCA will work only if it addresses several important dilemmas in the nature of foreign aid conditionality and the terms of reference of foreign aid organizations. 相似文献

This is the report of a five month study, undertaken by Sundridge Park Training Technologies in association with Guildford Educational Services to assess the potential of smart card technology to support learning and the management of learning. The study had two strands—the state of the art of the technology and its potential for supporting, delivering and managing learning. In addition to a study of the literature and extensive discussions with people using smart cards, potential users of smart card and visionaries, the project team developed two illustrative systems using cards to store personal data relating to education and training. The term ‘smart card’ is often used loosely to describe three different types of card, each of which is similar in general shape and size to a traditional credit card. These are: memory cards, laser cards—and true smart cards incorporating a processor and memory. This study has been concerned with memory cards and smart cards. The focus for smart card applications has been predominantly financial: there are relatively few applications in education or training. A notable exception is the large scale project at the University of Bologna which uses smart cards to manage the progress and achievements of a large number of students in the Department of Electronics. The two illustrative systems provided valuable experience of using memory cards and smart cards in quasi‐real education and training applications. They highlighted the problems of limited memory capacities and confirmed the high level of user acceptance reported by other trials. We can expect considerable advances in the technology of both memory cards and smart cards over the next months and years. The memory capacities of both types of cards will increase many‐fold and the unit costs will fall as large quantities of cards are produced for financial applications. Education and training applications will benefit from this expanding market. The major surprise from the study was the level of interest in the work and the enthusiasm expressed by almost all of those who came to hear of it. The general level of awareness of smart card technology was found to be low. However, the requirement for a system which will enable individuals to manage and own their learning on an extended timescale was generally recognised. Some of the possible applications for smart cards and memory cards in education and training had emerged before the official start of the study and it is clear that the technology is potentially pervasive. The project team and those consulted identified a wide range of possible applications both in education and in training. These focussed on assessment, personal course planning and management, identification of relevant learning opportunities, and the ownership of learning. It was felt that, over the next few years, smart cards are very likely to be in common use as credit cards for financial applications. Therefore, their use for education and training should be planned now. The recommendations from the study are that: More detailed studies are needed to find out how smart cards and memory cards could be used by different organisations in a fully operational system; Standards should be established for smart card applications in education and training, similar to those governing financial applications; Applications should be developed after the standards have been established. To be convincing, these should take a case study approach with small pilot studies in a variety of contexts and must follow real needs rather than attempt to drive them; The case studies would then form the basis for a campaign to increase awareness of smart cards and their potential for education and training, together with a programme for building an infrastructure to support the proposed systems. The public sector should fund the task of developing standards and providing interfaces with existing educational systems and projects to demonstrate the feasibility of various applications. Since educational standards have a European dimension, the European Community may be a source of support for work in the area of standards. At the same time, private sector funding should be sought for skill development and career development systems in industry and in education. The Training Agency itself should consider the application of smart card technology to the control and management of the Youth Training Scheme (YTS). 相似文献

Conclusion Which is the better choice: general item bank software or a word processor program? Your answer is dependent upon your computer
skills, the amount of test development work you do, and the nature of investment your school is willing to make for software.
Both have their relative strengths and weaknesses. The trade-offs between the two approaches are real, important, and in time
will probably favor the item bank software.
At the moment, however, we recommend a good word processing program for most teachers. What can you expect the future to bring?
At a minimum, test preparation options will continue to expand and improve. We suggested earlier that the technology is changing
rapidly. For example even now you can place a printed copy of test items into an optical character recognition (OCR) scanner
(similar to a photocopy machine) and read the items into a digital form which either a word processor or a test generator
can use. Instead of having to type your collection of test items before selecting, editing, and printing them, the computer
will read them from the paper.
This new scanning technology, unfortunately, requires expensive software, powerful microcomputers, and the scanner itself
costs over $1000. In addition, the accuracy of the character recognition is not perfect—especially with less than the ideal
printed copy from which to work. It will be years before most of us have ready access to this technology. Even better options
will be available, however, don’t wait for the next major breakthrough. There will always be another breakthrough on the horizon.
You can start improving your test development process now 相似文献

During the next ten years, technical institute education in the United States should be expanded ten times while other forms of higher education are doubled. Only in this way will we be able to get efficient utilization of our scientists and engineers. The many developments in science and technology that will take place in the next decade will call for a greatly expanded technical manpower team, and the largest potential source of 1957. supply is the manpower pool composed of individuals with aptitudes that qualify them to become engineering technicians. We can produce twice as many engineering technicians as engineers for the invested educational dollar, for the engineering technician is graduated in two years while the engineer needs four years. Through better acceptance of the engineering technician by industry and the engineering profession, this much needed expansion is bound to be realized. 相似文献

Ciaran Sugrue 《Irish Educational Studies》2013,32(1):7-13
While ‘paradigm wars’ have raged internationally during the past decade in particular, the research community, qua community in the Irish context has been largely silent on these important issues. This paper provides a synthesis of key aspects of these international discourses against a brief historical backdrop of the field of educational research. Thereafter, this theoretical lens is used to interrogate the more than 200 papers published in Irish Educational Studies (IES) over a period of 10 years: 1996–2006. This analysis seeks to establish the relative health and quality of educational research in the Irish context, and in the third section of the paper, this analysis is the basis for discussion of lessons that may be learned from insights and understandings gained. The paper concludes that a more systematic and comprehensive review of educational research funding in the Irish context would be particularly apposite and timely, while also advocating the necessity for a comprehensive educational research policy and the creation of a national educational research council. In the absence of such endeavours, research is likely to remain fragmented, small scale and easily dismissed by policy-makers, thus enabling advocacy rather than evidence and research generated elsewhere to overly-influence educational reform, while failing to enhance and extend a comprehensive ‘native’ research literature, a vibrant research culture, while funding and systematically supporting and developing the next generation of educational researchers. In the absence of policy and funding, quality and capacity will continue to falter in a more complex, sophisticated interdependent world. 相似文献

Virtual organizations are goal-driven associations of intellectual agents working within the information space. The development of virtual organizations and their agents is a natural continuation of the long movement in western society towards organizing for efficient commerce and communication. For at least 800 years cities and traditional organizations fulfilled these purposes, but now with the advent of high-speed communication and rich interconnectivity, a general diaspora of commerce and education may be expected. All of the technology needed to nurture the rise of virtual organizations is in place, albeit in a primitive form. The authors argue that in the next decade this technology will reach such a level of sophistication that traditional universities and schools with their massive physical assets will no longer be sustainable, and will be replaced by virtual organizations delivering education and training with a minimum of physical infrastructure 相似文献

This article examines the development and ultimate demise of the Ultranet, a major ICT infrastructure project in the education system of the Australian State of Victoria. The case is interesting as it was a very large project, intended for 1500 schools and funded to $180 m (Au). The study traces the design and implementation of the project as a socio-technical innovation in education. Although there are examples of how this project worked very well, its uptake was less than anticipated. The study found that potential benefits from a very large project like this can be nullified by a number of factors including: change in sponsorship of the project, an over emphasis on security concerns, failure to enrol crucial stakeholders and a naive assumption by technologists that technology with potential benefits will always be accepted. The study also found that technology projects must be delivered where a need exists and one that, most importantly, is recognised by the stakeholders. This will also be the case in other education systems around the world. If resources are not to be wasted the problem must be clearly identified and its need accepted before a solution is proposed. The Victorian Government finally abandoned the Ultranet in June 2013. 相似文献

The Knowledge-Creating School 总被引：9，自引：0，他引：9

Moving into the knowledge society at a time when expectations of schools and teachers continue to rise creates an urgent need for better professional knowledge about the management of schools and effective teaching and learning. This demand arises in part because university-based researchers have not hitherto been very successful in either the creation or dissemination of such knowledge. It is argued that success in meeting this demand will continue to elude us as long as the conventional approaches to educational R&D persist. Patterns of knowledge creation and dissemination in high technology firms are suggestive of the conditions under which the creation of professional knowledge in education and its more rapid dissemination throughout the whole education service might flourish. The implications of this radical reconceptualization of knowledge creation and its dissemination in education are explored. 相似文献

Conclusion I have presented some of the problems on which the Orton Society has labored during the past three decades and some of the
issues needing battle in the next three.
Much has happened in the past 30 years. Many of the dreams of Orton and of the Society have been realized. But I do not think
anyone will wish to rest for long, for the victories have brought new problems. And so, to borrow a few words from Dr. Samuel
Torrey Orton: if we continue to be “sufficiently keen” and prove ourselves “clever enough,” it would seem that the labors
of our next 30 years may be as fruitful, and even more so, than those of our first thirty. 相似文献

Conclusions ILSs are here to stay. School boards, administrators and other decision makers interested in what they perceive as a way of
preparing their students to do well on standardized tests will continue to drive the purchases of ILSs upward each year. If
ILSs are to become more effective for the rapidly growing number of students from diverse backgrounds (including many students
of color) who will spend months and years using them perhaps it is time for ILS companies to consider changes in their approach
to design as opposed to “just tweaking” the current design. A good starting point for changes in the approach to the design
of ILSs would be to consider the importance of the awareness of cultural diversity in the design and to attempt to integrate
cooperative learning into the design as well. If ILS companies seriously consider these suggestions they can create a system
for the next two decades that has the potential to be more effective for the large numbers of students from diverse backgrounds
who are the main users of these systems.
His research interests include cooperative learning, instructional technology, and collaborative learning environments. 相似文献
