Abstract
As part of a project that is examining how to support teachers in the use of challenging
tasks and those teacher actions that encourage students to persist, we focused on the
activities of students and teachers during seatwork. We describe the nature of teacher
interactions with students, student behaviours when working on challenging tasks, and the
relationships between the two. Interactions that seemed most beneficial were brief, and
usually preceded by the teacher watching and listening to the students at work.
