“…At the turn of the twentieth century, the chairs in education were frequently held by professors whose profile and attributes were eclectic, and their contribution to educational research and to academic and professional programmes is not clearly defined (Schwenk, 1977/78;Brezinka, 1995;Härnqvist, 1997;Cruikshank, 1998;Gautherin, 2002;Späni, 2002). Only in a second phase, lasting the whole of the twentieth century, with an acceleration in the last decades of the century, in these two countries, as in many others, did academic chairs that clearly belong to the disciplinary field grow strongly in number, become definitively settled, and be held by representatives of the field who have a mandate for research and are socialised in the discipline (Escolano et al, 1980;Simon, 1994;Baumert & Röder, 1994;Campos, 1995;Charlot, 1995;Kloprogge et al, 1995;Rinne, 1995Rinne, , 2000Rosengren & Ohngren, 1997;Gretler, 2000;Bertolini & Tarozzi, 2002).…”
