Important changes have taken place in the field of educational technology over the last few decades due to leaps in informatics, the explosive growth of the use of computers in schools, and the popularization of the Internet as a tool for teaching and learning. This scenario demands a broader understanding of the educational potential of new resources and didactic materials available to schools and innovative modes of individual and collective action in an increasingly digital society. Such changes have been faster since the start of the 21st century, which saw increased interest in educational technologies and many researchers orienting their studies to the modus operandi of the process of teaching and learning mediated by various types of digital technologies, be they presential, non-presential, hybrid, mobile, collaborative, cooperative, interactive, individualized, assistive, active, ubiquitous, and so on. With this, research in the field of educational technology has been consolidated and has begun to adopt methods of qualitative research that take account of this diversity of objects. This article seeks to point out the contributions of qualitative research methodologies in the formatting of this field of knowledge in Latin America. This is based on an examination of the most widely used scientific journals in the region, drawing on almost 100 articles published between 2016 and 2017. The analysis indicates that educational technology is evolving in Latin America, mainly due to the continuous and accelerated advance of digital information, communication, and expression technologies (DICETs). At the same time, there remains a great lack of scientific journals in the area, an issue that must be addressed given the strategic importance of this field of knowledge for the universalization of education in Latin America. Peer-reviewed journals have prioritized studies based on research and development (R&D) methods that emphasize media engineering for education and have a predominance of case studies. But they also present research problems related to qualitative issues that arise from the use of DICETs in specific teaching and learning situations. The scenario under analysis shows that research in this area has gradually evolved from a strongly technical perspective to a humanist one through qualitative analyses focusing on the limits and possibilities of DICETs. Thus, they raise important clues for future research, such as the challenges of adopting collaborative and interdisciplinary research approaches aimed at better understanding the processes and educational relations mediated by technologies; the new possibilities of hybrid education that can be addressed in different school contexts; and the question of teacher training for this new scenario. Such developments are crucial for advancing knowledge about educational technology in Latin America.
