Few articles in the field of international and comparative education have been as influential in academic circles and among some donor-agency personnel as Philip Foster's "The Vocational School Fallacy in Development Planning" (1965). This article went to the heart of the long-running (and continuing) debate about whether schools and their curricula can influence society through changing student attitudes towards jobs and work–or whether schools and their pupils are themselves much more influenced by the surrounding economy and by the patterns of work and rewards that exist in the surrounding urban and rural areas. During the period immediately following the independence of many African countries, it was commonplace to suggest that schools could deliver all kinds of attitude change (e.g., towards nation building, good citizenship, and rural development). Foster, however, argued that "schools are remarkably clumsy instruments for inducing large-scale changes in underdeveloped areas" (1965a, p. 144). Foster's message came at a time when a whole series of innovations were being introduced to deal with a sudden surge in unemployment in the developing world among those who had finished primary school, as well as the flight of young people from subsistence agriculture in rural areas. The most famous of these schemes was Education for Self-Reliance, developed by Tanzania's first president, Julius Nyerere.
Foster's warning about the limitations of schooling to change society arrived during the 1960s, a decade that saw many new and more instrumental approaches to schooling (from manpower planning to educational planning). These were frequently about engaging the schools in the creation of high-level manpower for the rapidly Africanizing civil service, but they also implied that schools could directly contribute to the modernization of traditional societies.
Foster's critique of these visions for engaging schools in the transformation of their surrounding societies was derived from an in-depth analysis of Ghana and from a detailed knowledge of its educational history prior to independence in 1957, when it was known as the Gold Coast. Foster was able to argue that, for well over a hundred years, Western education had been responsible for a massive amount of social change in this area, but that schools had very seldom functioned in the manner expected by the educators and the policymakers. In the new era of rational education planning and the new discipline of the economics of education (which involved looking at education as human capital and calculating the costs and benefits of different mixes of education), Foster's research was a vivid testimony to what he called the "unplanned consequences of educational growth" (1965b, p. 303).
At the heart of this debate lay the issue of vocationalism and its relationship to economic growth. Should not schools, the argument went, and especially those in predominantly agricultural societies where the formal sector of the economy could only absorb a very small proportion of the economically active population, keenly prepare young people with a substantial measure of the practical, agricultural, and technical skills needed for the transformation of their societies? Foster's answer was that, in Ghana, missionary societies, colonial governments, and the new independence government had frequently been attracted by the apparent logic of this position, and had sought to use schools in this instrumental way. But the plain truth was that "the educational history of the Gold Coast is strewn with the wreckage of schemes" based on these assumptions (1965a, p. 145).
Foster's explanation for these failures was that pupils are very realistic and are able to work out what is in their best career interests, regardless of the orientations schools seek to provide. In particular, he argued that schools had been very shrewdly used by pupils as a gateway to the modern sector of the economy–and as an escape from poor prospects in many rural areas. The core argument of the vocational school fallacy, according to Foster, is that "the schools themselves can do little about this. So long as parents and students perceive the function of education in this manner, agricultural education and vocational instruction in the schools is [sic] not likely to have a determinative influence on the occupational aspirations and destinations of students. Aspirations are determined largely the individual's perception of opportunities within the exchange sector of the economy, destinations by the actual structure of opportunities in that sector" (1965a, p. 151).
