Classroom Discussions

Abstract

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.
