1 Introduction

“At sector and institutional levels the notion of an iron triangle for education has been posited, linking firstly access, quality and cost (and latterly accessibility, quality and efficiency) in order to suggest means of using open, distance and e-learning (ODeL) and/or OER for widening access to higher education for the same or lower cost without compromising outcomes (Immerwhar et al, 2008; Daniel and Uvalic-Trumbic, 2011; Mulder, 2013)” Lane, 2014

Figure "The Iron Triangle of Education" (below) shows the basic triangle originally defined by Uvalic-Trumbic (2011) according to Lane (2014).

The Iron Triangle of Education (Lane, 2014)

Each factor - scale, quality and cost - are represented by equal length sides. “The assumption is that increases in one point of the triangle will inevitably lead to stresses in the other points. [...] These changes make the basic point that with conventional teaching in classrooms there is little scope to alter these factors advantageously because improving one factor will worsen the others. Pack more students into the class and quality will be perceived to suffer (Figure 1- A1). Equally, try to improve quality by providing more learning materials or better teachers and the overall cost will go up (Figure 1- A2). In effect the area under the triangle does not change because of these physical limitations.” (Lane, 2014).
