Purpose: The purpose of this report is to elevate the collective understanding of what it means to be and become a TESOL professional and what differentiates "TESOLers" from other teachers. We have intentionally prepared this report as an Open Educational Resource (OER), so it can be freely shared with an international audience. Methods: This report synthesizes literature relating to signature pedagogies, teacher training, and educational technology. Results: We explore the surface, deep, and implicit structures of three signature pedagogies of TESOL teacher education: (a) developing the TESOL knowledge base; (b) cultivating reflective practice; (c) engaging in a TESOL practicum. We also situate TESOL within a technology, content, and pedagogical content (TPACK) framework as a means to further understand how and why TESOL teacher education can and should incorporate technology in a variety of ways. Implications: TESOL is a relatively young discipline and has come of age during a time when technology has emerged as an essential element of teaching and learning. As such, TESOL teacher education programs must address technology as a key element of teacher preparation for the profession.
