Multi-site studies in SLA research: Opportunities for increasing ecological validity

Organisatrices: professeure Nicole Ziegler, University of Hawaiʻi at Mānoa & professeure Kara Moranski, University of Cincinnati

Investigations conducted via partnerships across multiple sites hold tremendous potential for empirical SLA research. Expanding study populations promotes ecological validity (the extent to which results are generalizable in real-world settings) given that including groups representing multiple geographic regions bolsters demographic diversity. Increasing participant groups through multi-site collaborations also strengthens statistical power and thus better equips researchers to detect significant effects (Fields, 2009). Though these benefits have made multi- site studies hallmarks of various applied sciences, the great majority of contemporary SLA research is conducted within the context of a single institution, laboratory, or classroom.

Discussants in this colloquium will explore the value of multi-site studies for creating new empirical knowledge within SLA as well as the logistical and methodological challenges presented by such collaborations. Presentations will include examples of multi-site SLA studies in distinct experimental contexts (intact classrooms, study-abroad, laboratory settings) and will focus on statistical methods that enable the analysis of data from multiple participant pools (multilevel modeling, ANCOVA, etc.). Discussants will also address procedural and funding considerations for multi-site studies. Finally, areas of SLA investigation particularly well suited for future research will be identified.
