Body scanners allow doctors to find and treat conditions such as tumours in their early stages when the chances of treating them successfully are much greater. Patient monitoring Computers are used in hospitals to monitor critically ill patients in intensive care units. The patient has sensors attached to him which detect changes in heart rate, pulse rate, blood pressure, breathing and brain activity. If any of these fall below a preset level the computer sounds an alarm and alerts the medical staff.
How have radio and TV broadcasting been used in education? There are three general approaches to the use of radio and TV broadcasting in education: The radio lessons, developed around specific learning objectives at particular levels of mathematics, science, health and languages in national curricula, are intended to improve the quality of classroom teaching and to act as a regular, structured aid to poorly trained classroom teachers in under-resourced schools.
And with its economies of scale, it has proven to be a cost-effective strategy relative to other interventions.
The Use of ict in the field was launched in Mexico in as a cost-effective strategy for expanding lower secondary schooling in small and remote communities. Perraton describes the programme thus: Centrally produced television programs are beamed via satellite throughout the country on a scheduled basis 8 am to 2 pm and 2 pm to 8 pm to Telesecundaria schools, covering the same secondary curriculum as that offered in ordinary schools.
Each hour focuses on a different subject area and typically follows the same routine—15 minutes of television, then book-led and teacher-led activities. Students are exposed to a variety of teachers on television but have one home teacher at the school for all disciplines in each grade.
The strategy meant combining community issues into the programs, offering children an integrated education, involving the community at large in the organization and management of the school and stimulating students to carry out community activities.
For these institutions, broadcasts are often accompanied by printed materials and audio cassettes. Each course consists of 15 minute lectures broadcast nationwide once a week for 15 weeks. Courses are aired over University-owned stations from 6 am to 12 noon. Students are also given supplemental print materials, face-to-face instruction, and online tutorials.
But unlike direct class instruction, school broadcasting is not intended to substitute for the teacher but merely as an enrichment of traditional classroom instruction.
School broadcasting is more flexible than IRI since teachers decide how they will integrate the broadcast materials into their classes. In developing countries, school broadcasts are often a result of a partnership between the Ministry of Education and the Ministry of Information.
In a sense,any radio or TV programming with informational and educational value can be considered under this type. Some notable examples that have a global reach are the United States-based television show Sesame Street,the all-information television channels National Geographic and Discovery,and the radio programme Voice of America.
The Farm Radio Forum, which began in Canada in the s and which has since served as a model for radio discussion programs worldwide, is another example of non-formal educational programming.
Audioconferencing involves the live real-time exchange of voice messages over a telephone network. When low-bandwidth text and still images such as graphs, diagrams or pictures can also be exchanged along with voice messages, then this type of conferencing is called audiographic.
Videoconferencing allows the exchange not just of voice and graphics but also of moving images. Web-based conferencing, as the name implies, involves the transmission of text, and graphic, audio and visual media via the Internet; it requires the use of a computer with a browser and communication can be both synchronous and asynchronous.
Teleconferencing is used in both formal and non-formal learning contexts to facilitate teacher-learner and learner-learner discussions, as well as to access experts and other resource persons remotely.
In open and distance learning, teleconferencing is a useful tool for providing direct instruction and learner support, minimizing learner isolation.The five key challenges in implementing ICT for development.
Through their field programs and local partners, INGOs have a deep understanding and a close working relationship with the poor on. The ICT Development Index ranks and compares the level of ICT use and access across the various countries around the world.
In ITU (International Telecommunications Union) released the latest rankings of the IDI, with Denmark attaining the top spot, followed by South Korea. Medical Virtual Reality.
