This report describes the activities of the Radio Mathematics Project of the Institute for Mathematical Studies in the Social Sciences (IMSSS) during the 1974-75 fiscal year. This project is funded by AID for the purposes of (1) developing and testing a cost-effective system of radio instruction in elementary mathematics for developing countries,…

The Radio Mathematics Project was established to design, implement, and evaluate a prototype system of teaching elementary mathematics using radio as the major medium of instruction. The project, working in rural and urban primary schools in Nicaragua, presents daily mathematics lessons in second and third grade classrooms. Each lesson has a 30…

Though the use of educational radio has fallen from fashion, for three reasons it deserves reconsideration as a valuable educational tool: 1) it is economical, costing only a fraction of the required expense to deliver the same material via television; 2) the effectiveness of radio-based instruction has been shown to be equal to that of…

In 1977 the Radio Mathematics Project provided radio lessons in mathematics for 2,800 students enrolled in 105 second-grade and third-grade classes in Nicaraguan public schools. Comparisons between randomly selected experimental and traditionally taught groups show that the achievement at the end of both second and third grade was significantly…
