  3. 3. What is dialogic teaching? Collective: teachers and children address learning tasks together, as a group or as a class. Reciprocal: teachers and children listen to each other, share ideas and consider alternative viewpoints. Supportive: children articulate their ideas freely, without fear of embarrassment over "wrong" answers; and they help each other to reach common understandings. Cumulative: teachers and children build on their own and each other's ideas and chain them into coherent lines of thinking and enquiry. Purposeful: teachers plan and steer classroom talk with specific educational goals which are chosen based on prior lessons.
