This naturalistic study integrates specific "question moments" into lesson plans to increase pupils' classroom interactions. A range of tools explored students' ideas by providing students with opportunities to ask and write questions. Their oral and written outcomes provide data on individual and group misunderstandings. Changes to the schedule of lessons were introduced to explore these questions and address disparities. Flexible lesson planning over 14 lessons across a 4-week period of high school chemistry accommodated students' contributions and increased student participation, promoted inquiring and individualised teaching, with each teaching strategy feeding forward into the next.
