Teacher questioning is integral to teaching and learning in mathematics classrooms. Research indicates that purposeful questioning in mathematics classrooms engages, motivates, and deepens student understanding and critical thinking during mathematical discussions. This chapter used both qualitative and quantitative approaches to examine the levels of questions and questioning strategies used by elementary teachers while facilitating mathematical tasks. Findings indicate that teachers use more funneling questions than focusing questions while facilitating math tasks. Most teachers hardly arrive at that reflection and justification level of questioning. Teachers found the Pivothead glasses to be effective not only for teacher self-assessment of their questioning techniques but also for gathering data on student thinking. Regression analysis indicates that education, experience, and location are the most important variables influencing the level of questions asked and questioning strategies used by the teachers.
Chapter Preview


Classroom discourse (verbal interaction including questioning) has been examined and evaluated by many researchers in order to reflect and improve upon the quality of teaching and training (Faruji, 2011; Flanders, 1970; Freiberg, 1981; Nasir & Abdul, 2006). The value in asking good questions is something that cannot be underestimated in mathematics education. The kind of reasoning and problem-solving abilities students construct and communicate during mathematical tasks depends on the teacher’s types of questions and questioning techniques (Moyer & Milewicz, 2002). Research studies in recent years have seen a surge of interest in the relationship between teacher questioning and student’s knowledge levels; but student’s level of understanding can be evaluated by teacher questioning strategies as an assessment tool (McCathy, Sithole, Mcarthy, Cho & Gyan, 2016).

Facilitating effective mathematical tasks requires that the teacher ask open-ended questions that may lead to many right answers, however, the learning environment becomes complex and less predictable. Novice teachers grapple with interpreting and understanding students’ responses in an environment that utilizes open-ended questioning. Lampert (1986) noted that for teachers to handle such an environment, it requires principled knowledge of mathematical concepts and understanding of how students think and reason mathematically. McCathy et.al. (2016) argued that “Whereas experienced teachers have a repertoire of easily accessible strategies and pedagogical content knowledge, some teachers may have difficulty interpreting and responding to unexpected answers from children…Developing effective questioning strategies… could be an integral focus in mathematics… classroom discourse” (p.80).

There is not much known about how teachers implement questioning in the teaching of mathematics. Aizikovitsh-Udi and Star (2011) note that “We assume that good teachers ask good (and lots of) questions to their students. Yet this general recommendation fails to consider important questions about how teachers implement question asking” (p. 1354). Many agree that teachers should be trained on how to implement higher-order questioning techniques. Teachers who can question appropriately and effectively at various levels of the Bloom’s Taxonomy are better able to discern the range of students’ thinking (McCathy et.al., 2016). The National Council of Teachers of Mathematics (NCTM) (2014) developed categories of types of questions used in mathematics teaching. The categories align with the levels of Blooms Taxonomy in that, various types of questions categorized by the NCTM use similar words (or action verbs) found in the levels of Blooms Taxonomy. The Appendix summarizes the types of questions and the categories of questions that mathematics teachers should ask their students. These questions are adapted from NCTM (2014) and aligned to Blooms Taxonomy levels of cognitive thinking. The summary helps to show that the framework developed by the NCTM is grounded in what teachers already know about Blooms’ Taxonomy.

Key Terms in this Chapter

Pedagogy: Teaching methods that integrate classroom discourse.

Funneling Questions: Questions that lead to one right answer.

Rural: Characterized by geographic isolation and small population size (a place with less than 2,500 people). Also characterized by lack of up to date educational resources.

Location: Rural or urban school districts.

Urban: Characterized by proximity to shopping centers and has educational facilities that provide education to students who live in metropolitan areas.

Classroom Discourse: The language that teachers and students use to communicate with each other in the classroom, this language includes discussions and questioning techniques.

Focusing Questions: More open-ended questions that probe students to explain how they solve a problem; there is no one-way of solving a problem.

Wearable Technology: Technology worn on the body.
