“…In other words, most studies using SNA in education (e.g., Author A, 2012c;Curşeu et al, 2012;de Lima, 2007;Hommes et al, 2012) have used a so-called closed (ego-centric) network analysis, using a predescribed list of participants (e.g., a class list). In contrast to student-focussed studies, in teacher-focussed research it is well-documented that teachers primarily identify their own identity based upon their grade-level , departmental structure (Daly & Finnigan, 2010;de Lima, 2007;Moolenaar et al, 2012), and particularly in higher education based upon their academic discipline (Author B, 2008;Clarke & Reid, 2012). For example, after a typical small-group activity in a professional development programme, a participant will return to his/her daily practice and will again work and interact with (the same) departmental colleagues, who may have different beliefs and values towards teaching and learning than those discussed during the professional development programme (Author A, 2013b;Author B, 2008).…”
