Over the past decade, interest in language teacher education and professionalization programs has increased significantly mainly due to global educational reforms, which have been driven by internationalization, multilingualism, the rise of new literacy and the incorporation of technologies. These reforms, based on the challenges of knowledge societies and networks, have created the need to re-evaluate and reconceptualize teacher training and teacher professional development as a "fundamental connection to teaching" (Bryant et al., 2008; Vélaz de Medrano & Vaillant, 2009; Espinosa, 2012; Johnson and Golombeck, 2018). The main objective is, then, to “prepare the new generations within an increasingly uncertain and demanding global scenario” (Pérez Ruíz, 2014, p 114). This publication addresses work on the education of language teachers in a variety of sociocultural, educational and institutional contexts carried out in Mexico and Latin America with various methodological designs and approaches from different theoretical perspectives. Therefore, in the context of current challenges, we seek to promote the exchange, discussions of experience and results of research and reflection that can influence the direction and implementation of language policies regarding teacher education and teacher professionalization for language teaching.
