“More recently, however, a re-evaluation of display questions has taken place. This is based on the observation that there are different ways in which display questions can be asked in classrooms. One is for the teacher to ask a series of questions in a drill-like format such as ‘Do you have a brother?’, ‘Does he have a brother?’, ‘Do you have a sister?’, ‘Does she have a sister?’ In this context, display questions do not have a meaningful or communicative purpose. In other contexts, however, display questions can serve important pedagogic and interaction functions.”
