“…Given the relatively short history of ESSCs, it is not surprising that there are gaps in our knowledge about these support systems as a whole. For example, although many of the experiences linked to a student's decision to leave engineering can be mitigated by appropriately directed student interventions (e.g., Allen, 1999;Amenkhienan & Kogan, 2004;Fletcher, Newell, Anderson-Rowland, & Newton, 2001a;Fletcher, Newell, Newton, & Anderson-Rowland, 2001b;Single, Muller, Cunningham, Single, & Carlsen, 2005;Vesilind, 2001), a shortcoming in our current understanding of these efforts is that co-curricular support is practice oriented: much of the existing research about ESSCs and interventions focuses on recruitment and retention numbers or measures such as student satisfaction (Brainard & Carlin, 1998;Hermond, 1995;Lam, Doverspike, & Mawasha, 1999;Ohland & Zhang, 2002;Van Aken et al, 1999). While these measures are important, little of this research explains how the co-curricular support provided by ESSCs is intended to work or the ways student-support practitioners aim to improve the student experience.…”
