The current ‘widening participation’ and ‘key skills’ agendas in higher education present the challenge of developing curriculum models that can accommodate a more heterogeneous student body. Drawing primarily on the South African experience, and similar findings from Australia, this article examines various forms of provision in terms of intended target group, assumptions, goals and curriculum context. A distinction is made between separate, semi-integratedand integratedapproaches and associated models. On the grounds of both educationally relevant theory and actual practice, it is argued (...) that ‘separate’ provision of the ‘academic support’ type has a limited impact, and that a mix of semi-integrated and integrated models of curriculum provision offers better prospects for helping a wide spectrum of students to succeed at university. Some implications for teaching and curriculum development are illustrated with reference to the Arts and Humanities. (shrink)
