This preliminary survey was designed to explore the possible use of students as teaching resources in the developing countries. In carrying out the survey, available literature was reviewed, visits made to selected ongoing projects in the United States, and interviews conducted overseas with indigenous educational researchers in Ghana, Sierra Leone, Nigeria, Viet Nam, Thailand, Indonesia, the Philippines, and Korea to determine the feasibility and appropriateness of this approach to meeting the educational needs of primary-aged children in underdeveloped areas. On the basis of successes already reported and an analysis of what kinds of programs would be most useful in developing countries considering their needs and resources, four general models of peer teaching were developed. The results of the overseas interviews suggested that versions of any of the four models could be used in almost any developing country, and that no one model held particular promise for a majority of the countries surveyed. Differences in requirements, traditions, and capabilities would strongly influence the potential applicability and effectiveness of any approach. With the help of information obtained during the survey, a research design was prepared which suggested the systematic exploration of peer teaching in developing countries. (Author/DDO)
