Classroom discussions are a common pedagogical approach that involve verbal exchanges of information between teachers and students. Given their importance to teaching and learning, classroom discussions have been the focus of extensive curricular mandates and, to a lesser extent, research over the last several decades. In traditional classroom discussions, the teacher tends to be situated at the center of the discussion. This type of discussion model is commonly referred to as a transmissionary model, where the teacher transmits knowledge and understandings and often leads the discussion by posing factual questions and responding to students’ answers by giving evaluative feedback. However, productive classroom discussions are better characterized by a dialogic model with students at the center of the discussion. When students are encouraged to ask thoughtful questions, give reflective responses, and challenge each other using reasoned arguments within classroom discussions, they are more likely to become builders and owners of their knowledge. Indeed, productive classroom discussions tend to ignite students’ engagement, thinking, and understanding of knowledge across academic content areas. When adopting a dialogic model, classroom discussions can advance students’ learning by promoting their basic and high-level comprehension of literary text, reasoning, and argumentation during mathematical sense-making, scientific reasoning, and model building and even second-language proficiency and communicative competence. While the overarching aim of classroom discussions is to enhance student learning across content areas (e.g., language arts, mathematics, science, or second-language learning), the various roles that teachers assume in each of the content areas may have different emphases that align with various content learning expectations. Optimizing classroom discussions requires specific considerations of the content-focused goal, teacher knowledge of content and discourse orchestration, student instruction on classroom talk, and context of content learning. Importantly, the potential and promise of productive classroom discussions can be realized by supporting teachers’ content-specific discussion practices through sustained professional development and by supporting students through explicit instruction about discussion.

A specific comparative framework that incorporates an interpretive process dedicated to developing a more complex understanding of teaching knowledge incorporates the specific local contexts in which studies on teaching knowledge are conducted. Research on teaching knowledge within the region grew and diversified from the 1980s and 1990s. There are two key thematic contributions of this body of research: the nature of teaching knowledge and pedagogical approaches to teaching specific curricular content focusing on early literacy. Points of comparison between the different contributions of studies addressing teaching knowledge can be found. Additionally, institutional and social inequalities are manifested in schools and education in Latin American countries. Teaching knowledge, which teachers produce in and adapt to different social spaces (in other words, through practice), is crucial for fostering the development and learning of the students who attend school under the challenging conditions of the schools in these countries.

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.
