“…The two development phases can be described in the context of growth phenomena; in particular the period from the late 1950s to the mid-1970s is described as 'the expansion of the education system' both in Switzerland (Criblez, 2001;Kussau, & Oertel, 2001) and abroad (Titze, 1999). Growth phenomena can be understood in two ways: first, as quantitative growth in the form of larger student cohorts, longer school careers, the lengthening of compulsory education, and the opening up and decentralisation of higher education (Criblez, 2001), which resulted in direct consequences for the education supply structure with regard to infrastructure and human and material resources (Kussau & Oertel, 2001); and second, as normative differentiation of the education system, thus easing transitioning between different school levels and types, at least as a political aim (Criblez, 2001).…”
