Teachers’ questions shape the instructional environment and the direction of mathematics discussions in critical ways (Boaler and Brodie 2004). Questioning can be used to drawout student thinking and create space for student discourse or to “funnel” student thinking toward a particular solution (Herbel-Eisenmann and Breyfogle 2005). The types of questions posed and the pattern of questioning used often reflect a teacher’s orientation toward students’ mathematical ideas and approach to teaching and learning.When teachers focus discussions on students’ mathematical ideas and ask questions that support students in explaining and justifying those ideas, they honor students as mathematical thinkers and open up space for students to learn from one other. As stated in Principles to Actions: Ensuring Mathematical Success for All, effective mathematics teaching “relies on questions that encourage students to explain and reflect on their thinking as an essential component of meaningful mathematical discourse” (NCTM 2014, p. 35). We posit that in addition to supporting discourse, such questions also create opportunities for students to engage in the Common Core’s (CCSSI 2010) Standards for Mathematical Practice (SMP).This article is the product of a research study on the relationship between teachers’ questions and student engagement in the SMP during whole-class discussions. Using classroom video gathered during the first year of a study of teacher professional development, we identified instances of student engagement in the SMP (Hammerman et al., forthcoming). We then analyzed the types of questions teachers asked students in discourse sequences that resulted in this engagement, as well as in sequences that did not. We looked for patterns in the types of questions asked and closely examined interactions between teachers and students to better understand how certain types of questions created or limited opportunities for student engagement in the SMP. We present and illustrate key findings about teacher questioning from our study and discuss the implications of these findings for classroom practice.
