Title: A Decomposition of the Teaching Practice of Building
We share a decomposition of building on MOSTs—a teaching practice that takes advantage of high-leverage instances of student mathematical contributions made during whole-class interaction. This decomposition resulted from an iterative process of teacher-researchers enacting conceptions of the building teaching practice that were refined based on our study of their enactments. We elaborate the four elements of building: (a) Establish the student mathematics of the MOST as the object to be discussed; (b) Grapple Toss that object in a way that positions the class to make sense of it; (c) Conduct a whole-class discussion that supports the students in making sense of the student mathematics of the MOST; and (d) Make Explicit the important mathematical idea from the discussion. We argue for the value of this practice in improving in-the-moment use of high-leverage student mathematical thinking during instruction.  more » « less

    Productive use of student mathematical thinking is a critical aspect of effective teaching that is not yet fully understood. We have previously conceptualized the teaching practice of building on student mathematical thinking and the four elements that comprise it. In this paper, we begin to unpack this complex practice by looking closely at its third element, Conduct. Based on an analysis of secondary mathematics teachers' enactments of building, we describe the critical aspects of conducting a whole-class discussion that is focused on making sense of a high-leverage student contribution.

    We used videotaped enactments of high cognitive demand tasks to investigate whether teachers who were engaged in the teaching practice of building—and thus were focused on having the class collaboratively make sense of their peers’ high-leverage mathematical contributions—provided scaffolding that supported the maintenance of high cognitive demand tasks. Attempting to build on high-leverage student thinking seemed to mitigate the teachers’ tendencies to provide inappropriate amounts of scaffolding because they: (1) believed the building practice required them to refrain from showing the students how to solve the task; (2) wanted to elicit student reasoning about their peer’s contribution for the building practice to utilize; and (3) saw the benefits of their students being able to engage in the mathematical thinking themselves.

    Productive use of student mathematical thinking is a critical yet incompletely understood aspect of effective teaching practice. We have previously conceptualized the teaching practice of building on student mathematical thinking and the four subpractices that comprise it. In this paper we begin to unpack this complex practice by looking closely at its first subpractice, establish. Based an analysis of secondary mathematics teachers’ enactments of building, we describe two critical components—make precise and make an object—as well as important subtleties of the establish subpractice.
