Since 2001, "Teaching English with Technology" (TEwT) has published hundreds of research articles to improve the quality of applying technology in language education and research. This collection of articles has covered many aspects of Computer-Assisted Language Learning (CALL); however, due to the importance of CALL teacher education and professional development, a research synthesis of the two decades of TEwT's articles holds the potential to screen the field at large over that time period. By examining the published articles on CALL teacher education and professional development, data analysis revealed that most of them focused on 'teachers' perceptions, attitudes, and experiences,' 'CALL practicum,' 'teachers' knowledge, literacies, and skills' and 'CALL affordances and hindrances'. This study might help as an extant inventory of CALL research interests over the first 20 years of the Journal's existence.
