The ability to question students effectively is, without doubt, one of a teachers most valuable assets. Through questions students can be led to make discoveries about the world, and to pose and solve their own problems. It must be recognised, however, that children may need tobe taught how to respond to different tyres of questions, and how to use questions to elicit the information they want. Despite the possibility that questioning can be overused (Wood, Wood, Griffiths, & Howarth, 1986), and the accusation that it can reduce the quality of conversational interchanges in the dassroom (Tizard & Hughes, 1984), the ability to question and respond to questions remain as important classroom behaviours: “Teachers and studerts who learn to comprehend the functions of the various types of questions can be expected to have more control over their enquiry” (Mann-Mandlebaurn, 1990).
