How have radio and TV broadcasting been used in education?

Radio and television have been used widely as educational tools since the 1920s and the 1950s, respectively. There are three general approaches to the use of radio and TV broadcasting in education:

1. direct class teaching, where broadcast programming substitutes for teachers on a temporary basis;
2. school broadcasting, where broadcast programming provides complementary teaching and learning resources not otherwise available
3. general educational programming over community, national and international stations which provide general and informal educational opportunities

The most notable and best documented example of the direct class teaching approach is Interactive Radio Instruction (IRI).This consists of “ready-made 20-30 minute direct teaching and learning exercises to the classroom on a daily basis. The radio lessons, developed around specific learning objectives at particular levels of maths, 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.” IRI projects have been implemented in Latin America and Africa. In Asia, IRI was first implemented in Thailand in 1980; Indonesia, Pakistan, Bangladesh and Nepal rolled out their own IRI projects in the 1990s. What differentiates IRI from most other distance education programs is that its primary objective is to raise the quality of learning – and not merely to expand educational access – and it has had much success in both formal and non-formal settings. Extensive research around the world has shown that many IRI projects have had a positive impact on learning outcomes and on educational equity. And with its economies of scale, it has proven to be a cost-effective strategy relative to other interventions.

Mexico’s Telesecundaria is another notable example of direct class teaching, this time using broadcast television. The programme was launched in Mexico in 1968 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 design of the programme has undergone many changes through the years, shifting from a “talking heads” approach to more interactive and dynamic programming that “link[s] the community to the programme around the teaching method. 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.” Assessments of Telesecundaria have been encouraging: drop out rates are slightly better than those of general secondary schools and significantly better than in technical schools. In Asia, the 44 radio and TV universities in China (including the China Central Radio and Television University), Universitas Terbuka in Indonesia, and Indira Ghandi National Open University have made extensive use of radio and television, both for direct class teaching and for school broadcasting, to reach more of their respective large populations. For these institutions, broadcasts are often accompanied by printed materials and audio cassettes.

Japan’s University of the Air was broadcasting 160 television and 160 radio courses in 2000. Each course consists of 15 45-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.

Often deployed with print materials, cassettes and CD-ROMS, school broadcasting, like direct class teaching, is geared to national curricula and developed for a range of subject areas. 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. Large broadcasting corporations that provide school broadcasts include the British Broadcasting Corporation Education Radio TV in the United Kingdom and the NHK Japanese Broadcasting Station. In developing countries, school broadcasts are often a result of a partnership between the Ministry of Education and the Ministry of Information.

General educational programming consists of a broad range of programme types – news programs, documentary programs, quiz shows, educational cartoons, etc. – that afford non-formal educational opportunities for all types of learners. 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 1940s and which has since served as a model for radio discussion programs worldwide, is another example of non-formal educational programming. It shows that you can also learn from lecturers with or without ID lanyards that represents certain University or college.

Satellite radio for education

EDUSAT, according to the Indian Space Research Organization (ISRO), is the first exclusive satellite for serving the educational sector. It supports radio broadcasting, along with audio-video on C-band and Ku-band, and is built around the concept of digital interactive classrooms and a multimedia system.

The satellite has multiple regional beams covering different parts of India, which theoretically enables programmes to be broadcast in relevant local languages – India has 18 official languages and over 1500 dialects. “India will require 10,000 new schools each year and meeting the teaching needs on such a scale [by conventional methods] will be impossible,” Madhavan Nair, chairman of ISRO told New Scientist at the launch of the satellite.

EDUSAT can provide connectivity to schools, colleges and higher levels of education and also support non-formal education including developmental communication. The nation-wide beams are being harnessed by agencies like IGNOU, NCERT and the All India Council for Technical Education (AICTE), to reach hundreds of Receive Only Terminals (ROTs) and Satellite Interactive Terminals (SITs) located in schools and colleges, many in remote areas.

Content generation is the responsibility of user agencies, but it is a matter of concern that, over a year after the satellite was launched, much of its capacity is lying idle.

Satellite access for radio broadcasting is also available on other platforms like WorldSpace, which offers a ‘development channel’ to agencies like Equal Access for networking community FM channels (as in Nepal), or for directly broadcasting development and educational programmes for community listening on WorldSpace receivers.

The promise of radio
U.K. Open University’s notable success with educational radio has demonstrated how invaluable radio can be for weak students, who benefit from the medium as a supplementary learning tool. But the use of radio for distance education in India, as mentioned earlier, has had mixed results. AIR’s educational broadcasts are

All the same, it has been amply proved that radio – rightly used – can improve educational quality and relevance, lower educational costs and improve access to education, particularly for disadvantaged groups. It is most effective when supported by trained facilitators, group learning, group discussion, feedback and the use of multimedia approaches.

There is no single ideal format for educational radio. Innovative programming like those developed by Sesame Workshop in Africa, for instance, offer some very effective approaches to non-formal education over radio. Recently, AIR agreed to a proposal from Sesame Workshop India to provide airtime on national and regional radio channels for locally produced versions of the universally popular ‘Sesame Street’. The programmes would be aimed at pre-schoolers, and would also provide under-served children with access to educational media, especially in rural areas.

India spends just 3.4% of its GNP on education. Over 35% of the population is illiterate, and the drop out rate in schools is staggeringly high, with 40% of all school-going children dropping out during the primary stage itself. The percentage of dropouts goes up to 67% by Class X. The Supreme Court of India (in 1993) has declared education of children up to 14 years to be a fundamental right, but school attendance is related to the perceived importance of education by parents, and also to socio-economic factors.

Despite rapid developments in communication technologies in the last few decades, radio broadcasting remains the cheapest mode of mass communication in India, catering equally to the needs of the rich and the poor, rural and the urban masses and reaching the remotest parts of the country. In a country where the literacy rate is 65%, and fewer than 50% of homes are electrified, the humble transistor radio plays a vital role in the country’s socio-economic and cultural development.

Rural and deprived communities, with low literacy rates and little access to formal education, stand to benefit the most from distance learning through community radio. If and when such communities are permitted to set up their own low power radio stations – and 4000 such community radio stations are possible in India, according to government estimates – then we could witness a revolution in education far beyond anything dreamt of by the purveyors of digital technology in a digitally divided country.

Using radio for education and community development is part of the 75-year-old Reithian ambition for radio broadcasting. Children and youth can be easily and cheaply trained, and the goals of universal primary and secondary education for all can be reached more easily with broadcast support. Among the poor and marginalized people of the country, radio could even create a new class of people – educated but illiterate.

Campus radio stations

In December 2002, the Ministry of Information and Broadcasting released its ‘Community Radio Guidelines’. Though nominally ‘community’ radio, the policy restricts the radio licenses under this scheme to ‘well-established educational institutions’. The licensing process proved so cumbersome that India’s first campus-based community radio station was launched only by 2004 (Anna University’s 90.4 Anna FM).

Against optimistic projections of 1000 campus stations coming up in a year, only 75 odd educational institutions have applied for a campus radio licenses so far, and of these, 15 stations have become operational.

Most of the campus licenses have gone to universities, engineering colleges and mass communications institutions, along with a Despite rapid developments in communication technologies in the last few decades, radio broadcasting remains the cheapest mode of mass communication in India that can benefit rural and deprived communities with low literacy rate and little excess to education sprinkling of well-heeled schools. Transmitting over a range of 5-10 kilometres, their FM radio stations are expected to serve the community beyond the campus walls, and to produce programmes ‘on issues relating to education, health, environment, agriculture, rural and community development’, according to the government’s Community Radio Guidelines (www.mib.nic.in).

Needless to say, the campus stations that try to live up to this confused mandate – and many of them do – sound very much like the public service broadcaster on which they seem to be closely modelled. You don’t need checks to maintain campus radio stations because of students support.

Radio for distance education

Despite rapid developments in communication technologies in the last few decades, radio broadcasting remains the cheapest mode of mass communication in India that can benefit rural and deprived communities with low literacy rates and little excess to education.

At a recent conference on Digital Learning in Delhi [18-19 October 2005], the participants sat bemused as Dr. Sugata Mitra of NIIT gave a very engaging account of his ‘Hole in the Wall’ project. Dr. Mitra explained how Delhi slum children with no education and no knowledge of English quickly picked up different computer functions, when given unsupervised access to a computer and the internet through a kiosk.

This project in ‘minimally invasive education’ was later extended to rural India, prompting a rather disbelieving audience to ask how the Hole in the Wall computers could function in remote and rural India, with erratic electricity supply, negligible telecom penetration and next to no maintenance.

Dr. Mitra gamely reeled off a catalogue of solar-powered UPS, self-rebooting, maintenance-free PCs, VSATs and other marvels of digital technology that could presumably keep computers running forever in the boondocks, but it sounded more like a Heath Robinson whimsy than a recipe for ICT in education.

Not surprisingly, the recommendations that emerged from the discussions emphasized “the need to think of ICT in education beyond computer aided learning and incorporate other technologies like community radio and other media. These mediums would not only be cost effective but also have a greater outreach potential.” [Digital Learning, Vol 1 Issue1, Nov-Dec 2005]

Classrooms and radio have always gone together, and radio has been used to teach everything from mathematics in Thailand (Galda, 1984) to civics education in Botswana (Byram, Kaute & Matenge, 1980). The first School Broadcast project in India was commissioned as early as 1937. Over the years, various educational radio projects have been carried out in the country, with mixed results.

Educational programmes on AIR
All the Primary channels of All India Radio (AIR) broadcast educational programmes on a regular basis on fixed time slots. AIR’s educational programmes are aimed at students as well as teachers of primary, middle, secondary and senior secondary schools, and are generally produced in collaboration with national educational agencies like NCERT (National Council for Educational Research & Training) and CIET (Central Institute of Educational Technology).

The Language Learning programme, popularly known as the ‘Radio Pilot project’, was started in 1979-80 jointly by AIR and the Department of Education (Rajasthan). Its aim was to teach Hindi to school children as their first language in 500 primary schools of Jaipur and Ajmer districts, on an experimental basis. The broadcasts were found to be useful in improving the children’s vocabulary, and a similar project was initiated in the Hoshangabad district of Madhya Pradesh.

Apart from AIR’s in-house educational programmes, the Indira Gandhi Open University (IGNOU) also broadcasts its educational programmes from AIR studios.

IGNOU-AIR Interactive Radio Counseling (IRC) was launched in May 1998 for students of Open / Conventional Universities. AIR Bhopal and IGNOU ran this as an experimental programme for a year, to provide academic counseling in various subjects and to instantly respond to students’ queries; but with its success, it was extended to other AIR stations. Presently, Interactive Radio Counseling is being provided every Sunday for one hour from 186 radio stations of All India Radio.

Gyan Vani

IGNOU’s own Gyan-Vani (Educational FM radio channel) was launched was in November 2001 to extend mass media support for education, suited to local needs. Gyan Vani channels are operating at present in 17 cities, and are scheduled to expand to a total of 40 cities by 2007. Gyan Vani stations operate as media cooperatives, with programmes contributed by different educational institutions, NGOs and institutions like IGNOU, NCERT, UGC, IIT, etc.

Each Gyan Vani station has a range of about 60 KM radius, covering an entire city or town and its surrounding area. Gyan Vani is meant for both conventional and non-conventional education, addressing local educational, developmental and socio-cultural needs. The stations broadcast in English, Hindi and the language or dialect of the region, for 4 to 12 hours daily.

During the current phase of private FM expansion in India, which is expected to cover 91 cities, it is reported that the government plans to offer 87 FM channels to be used exclusively for education. Of these, 36 would be used by IGNOU, while the other channels would be open to private players.

Community radio initiatives in India
In the absence of true community radio in India, a number of NGOs are using innovative methods for non-formal education through audio. School Audio through cable has been in operation in Budhikote village, Karnataka, since January 2002. The School Audio project is a spin-off of the ‘Namma Dhwani’ cable audio service being run in Budhikote by VOICES, a development communication NGO. Twice a week, educational programmes are ‘cable-cast’ to the local government school.

In the Kutch region of Gujarat, the Kutch Mahila Vikas Sangathan (KMVS), an independent organization of rural women, focuses on adolescent girls’ education, basic functional literacy within sangathan members and development of context specific educational curricula on different issues for literates and neo-literates.

In 1999, KMVS launched a weekly radio programme ‘Kunjal Panchchi KutchJi’ for expansion of literacy as well as to build an information network. The 30-minute serial is broadcast in the local Kutchi dialect, over All India Radio’s local stations in this region of vast distances and poor communications. constantly hampered by the lack of radio sets in classrooms, the difficulty of coordinating school broadcasts with class-room timings and more significantly, by the lack of good broadcasters who have a passion for education and conversely, of teachers who are also good broadcasters.
