Over the last forty years, the field of Second Language Acquisition (SLA) has been pushed to expand outside of its early, narrowly defined theories into something more social, environmental, and human. In this evolutionary effort to “shift” a fairly young field, scholars have worked to outline SLA’s history and recommend new directions for research (Gass & Selinker, 2008; Larsen-Freeman & Long, 1991; Lightbown & Spada, 2016; VanPatten & Williams, 2015).
