This article focuses on both research and practice relating to academically productive classroom discourse. We seek to “expand the conversation” to include newcomers to the field of classroom talk, as well as practitioners and youth researchers who want to contribute to knowledge building in this area. We first explore a variety of traditions, questions, and methods that have been prominent in work on classroom talk. We also summarize some key findings that have emerged over the past several decades: • Finding 1: Certain kinds of talk promote robust learning for ALL students. • Finding 2: The field lacks shared conceptualizations of what productive talk is and how best to characterize it. • Finding 3: Dialogic discourse is exceedingly rare in classrooms, at all grade levels and across all domains. • Finding 4: A helpful way forward: conceptualizing talk moves as tools. Following the presentation of each research finding we provide a set of commentaries—explicating and in some cases problematizing the findings. Finally, we provide some promising approaches that presume cultural and linguistic assets among both students and teachers, including curricular programs, teacher education, professional development programs, teacher research, and intergenerational communities of inquiry. In all of this, we try to make our own assumptions, traditions, and governing gazes explicit, as a multi-generational and multi-role group of authors, to encourage greater transparency among all who work in this important and potentially transformative field of study.


Critical discourse analysis (CDA) is a cross-disciplinary methodological and theoretical approach. At its core CDA explores the intersections between discourse, critique, power, and ideology which hold particular values for those teaching in developing contexts. CDA has emerged as a valuable methodological approach in cultural and media studies and has increased in prominence since the 2010s in education research where it is drawn on to explore educational policy, literacy education, and identity. This research has intersected with the field of information systems which has explored the dominant discourses and discursive practice of how information and communication technologies (ICTs) are viewed in policy and the contradictions between rhetoric and reality. It has also been drawn on in research in developing contexts to critique the role of ICTs in education. A brief historical background to CDA and overview of the key components of the approach will be provided. How CDA has been drawn on in educational studies will be examined and research on CDA will be highlighted to explore discursive practices of students and the influence of students’ digital identities on their engagement with and experience of online learning. By focusing on four key constructs of CDA—namely meaning, context, identity, and power—the potential of CDA to critically investigate how students’ are constructing their technological identity in an increasingly digital world will be demonstrated, particularly as examples of research emanating from developing contexts will be drawn.
