“…Sociological research in the UK and elsewhere, however, has tended play down the importance of teaching or school type effects, from the landmark Coleman Report onwards (Coleman et al , 1966; Jencks et al , 1972; Halsey et al , 1980), suggesting that quality of teaching or school resources makes little difference to the grades of students. Moreover, where they are found, such effects are generally attributed to peer effects—the ability mix of the children in a school—rather than the influence of teaching per se (Zimmer & Toma, 2000; Sullivan & Heath, forthcoming). Recent sociological research making use of cohort studies in Britain has, however, begun to identify the presence of teaching effects (Blundell et al , 1997; Sullivan & Heath, 2003, forthcoming).…”
