Interactive radio for education

Interactive Radio Instruction (IRI) is an instructional tool designed to deliver active learning by radio. It delivers daily 30-minute radio broadcasts that promote active learning and are designed to improve educational quality and teaching practices in schools and to deliver a complete basic education to learners not in school.

Data gathered between 1975 and 2000 demonstrated that Interactive Radio Instruction (IRI) had improved learning outcomes in conventional classrooms by between 10% and 20% when compared with control classrooms not using IRI.

IRI is an effective delivery mechanism for in-service professional development, as teachers are able to actively employ improved instructional techniques in the classroom while undergoing radio-based training. Teachers not only demonstrated a better understanding of pedagogical concepts emphasised by broadcasts, but more frequently utilised active learning and student-centered techniques in lessons independent of radio guidance.

The manual looks into the aspects of learning outcomes by subject, on the impact of IRI on pre-primary and early childhood learning outcomes, radio-based in-service professional development for primary school teachers.

The document has been broadly organised in the following sections:

- Student learning outcomes by subject area

- Student learning outcomes in early childhood education

- Teacher professional development observation outcomes

- Student learning outcomes with marginalised populations

Citing examples from various countries the manual highlights the impact of IRI on the learning outcomes of four key marginalised groups: girls, orphans and vulnerable children, learners in fragile states, and those in rural areas.

A review of the learning outcomes of various countries brought to light some of the successful, and not-so-successful, IRI experiences. Key findings of the research revealed that without adequate information on student attendance, quality of teacher training and consistency of teacher attendance, it was impossible to draw definitive conclusions regarding the marginal impact of IRI on student learning.Students not only can create NFL, MLB, NBA & NCAA emblems but any of their favorite team easily.

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.

Radio in Education

From the start, in both Europe and America radio was greeted with hopes for its pedagogical value. Radio had the power to bring the world to the classroom, and programs could be presented as textbooks of the air.

In America, commercial and educational stations received licenses starting in the 1920s to produce classroom broadcasting, and eventually national networks also provided educational programs. Even though most programs were in line with traditional school subjects, some attempted to connect this content with progressive ideas about education and democracy. Radio allowed children and teachers to engage in the production of programs, preparing talks on, for example, automobiles, farming, and science. Together with the fact that parents supplied schools with radio receivers, this reflected a certain degree of local engagement in the implementation of radio in schools. However, this is not a perspective that has been emphasized in research. On the contrary, the organization of radio in education in America has been described as top down implementation. One example of this was the fact that superintendents, not teachers, were supposed to answer questionnaires, indicating that teachers were not included in the implementation process.

In contrast to America, broadcast systems in Europe were organized as nationwide networks that could be used for the inculcation of national values and virtues. Issues regarding educational as well as social and cultural policy were included in the broadcast organizations–in other words, they became part of welfare policy. In this context, children became a special interest.

In Scandinavian countries and Britain, special departments for educational programs were organized in the late 1920s or early 1930s. In general these programs were in line with the overall curriculum. However, a study on the use of radio in classrooms in Sweden reveals that there were contrasts between the content of ordinary schoolbooks and the content of radio programs. Radio programs emphasized contemporary progressive ideas on education and progressive political notions that were not represented in schoolbooks at that time. Citizenship, a new subject, was also given a particularly radical formulation in the school programs. This meant that children who listened to educational programs on the radio, discussed the programs, and did assignments on them, encountered views of society that differed from prevailing traditional middle-class representations. Reoccurring subjects included the everyday lives of the working or lower-middle classes as well as the need for health reform and an expanded welfare system.

In Sweden, educational broadcasts addressed children not only as future citizens but also as active contemporary citizens. Children were included in the actual broadcasts, where they were displayed, with references to famous scientific explorers like Sven Hedin, as competent explorers of their own society. Further, these children were enlisted to represent various parts of society in accordance with notions of society proposed by progressive policymakers. Each pupil was supposed to have his or her own program sheet where each program was presented in texts and pictures. The notion was that the material should help children to create “listening pictures” (hörbilder) when listening to programs. This practice was implemented out of a strong belief that a will to change the way people thought had to start with strategies that changed the way they talked.

In contrast to America, and in spite of the centralized organization, in Sweden teachers were included in the implementation of radio in education. They participated continually in surveys where they reported their own and the pupils’ responses to programs. Active teachers were invited to annual conferences about the use of radio in classrooms. It was argued by teachers and by the organizers of school broadcasts that elementary schoolteachers were more competent than academics and experts in communicating with pupils and therefore were invited to produce programs.

In Britain, educational radio programs were regarded as an important way to influence individual children and adolescents when they had problems or needed guidance in societal matters. Radio was also used to inculcate new notions of citizenship.

Further Research

Studies of children’s radio programs, particularly educational programs, offers an area of research that brings new perspectives to social, cultural, and political history. Such research also expands investigations of children’s increased visibility and status as a special group in society, for instance as reflected in the UN CONVENTION ON THE RIGHTS OF THE CHILD (1989). Children’s programs provide material for inquiries into children’s place in society as well as representations of childhood from a historical perspective, particularly during the period from 1920 to 1960, when radio was regarded as the major electronic medium in society. It is also a field well attuned to further developments of theoretical and methodological issues. In addition to actual programs, manuscripts, program sheets, and other documents concerning children’s broadcasts, a number of studies measure children’s reading and comprehension skills in relation to radio. Such materials could be used to investigate the systems of knowledge and meaning that have affected the child in different decades of the twentieth century.

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.
