Talking with others about ideas and work is fundamental to learning. But not
all talk sustains learning. For classroom talk to promote learning it must be
accountable—to the learning community, to accurate and appropriate knowledge,
and to rigorous thinking. Accountable talk seriously responds to and further
develops what others in the group have said. It puts forth and demands knowledge
that is accurate and relevant to the issue under discussion. Accountable talk
uses evidence appropriate to the discipline (e.g., proofs in mathematics, data
from investigations in science, textual details in literature, documentary
sources in history) and follows established norms of good reasoning. Teachers
should intentionally create the norms and skills of accountable talk in their
classrooms.
