This study had two purposes. First, it aimed to provide an analysis of the types of questions teachers use to promote thinking, problem-solving and reasoning in their students. Second, it aimed to provide an analysis of the types of discourse the students used to problem-solve and reason during their small group discussions. The results showed that the teachers used a range of questioning strategies from those that probed for information and challenged children’s perspectives to those higher-level questions that required children to provide reasons, make connections or think meta-cognitively.
