Four levels of primary education were developed through a combination of radio lessons and supplementary print materials and evaluations showed that students almost as well or better than children in full-day conventional schools. Ten years after its inception, the Government still broadcasts the series. Subjects included math, science. social, sciences, Spanish. A first and second grade math series is also broadcast in formal schools. Papua New science, The Radio Science programs were the first to be created Guinea grds 4-6 for upper primary and to use an inquiry approach. Because (1986-) of its higher demands on teachers, it requires a more intense teacher training component. It has been broadcast for ten years and under new privatization struggles, the National Dept. of Education and National Broadcasting Commission are negotiating how to continue to pay for airtime. Honduras math, grds 1-3 A new series of math programs called La Familia de los (1987-) NOmeros was produced to make the original math model more relevant. The series was based on mental math and enhanced the teacher's role. A total of 465 lessons were produced. While it was not successfully institutionalized, the IRI methodology was changed to meet newer needs in adult education. Bolivia math, The Bolivia math programs were a more in depth (1987-) grds 1-5 adaptation of the Nicaraguan series. The first three years were adapted and two subsequent years were created. IRI Math has been broadcast for 10 years and has been a part of the national curriculum. In 1997, the Government is looking for ways to make IRI programming consistent with Educational Reform.
