Making sense of student mathematical thinking: the role of teacher mathematical thinking

Abstract

In mathematical whole-class discussions, teachers can build on various student ideas and develop these ideas toward mathematical goals. This requires teachers to make sense of their students' mathematical thinking, which evidently involves mathematical thinking on the teacher's part. Teacher sense-making of student mathematical thinking has been studied and conceptualized as an aspect of teacher noticing and has also been conceptualized as a mathematical activity. We combine these perspectives to explore the role of teacher mathematical thinking in making sense of student mathematical thinking. In this study, we investigated that role using videobased teacher discussions in a teacher researcher collaboration in which five Dutch high school mathematics teachers and one researcher developed discourse based lessons in cycles of design, enactment, and evaluation. In video-based discussions, they collaboratively reflected on whole-class discussions from the teachers' own lessons. We analyzed these discussions to explore the mathematical thinking that teachers articulated during sense-making of students' mathematical thinking and how teachers' mathematical thinking affected their sense-making. We found five categories concerning the role of teacher mathematical thinking in their sense-making: flexibility, preoccupation, incomprehension, exemplification, and projection. These categories show how both the content and the process of teacher mathematical thinking can support or impede their sense-making. In addition, we found that the teachers often did not articulate explicit mathematical thinking. Our findings suggest that sense-making of students' mathematical thinking requires teachers to (re-)engage in reflective thinking with regard to the mathematical content as well as the process of their own mathematical thinking.

Exploring prospective teachers’ stances in making sense of students’ mathematical ideas

“…There is indeed a spectrum of manners or positions that teachers can take to make sense of students' ideas-what are generally referred to as stances in making sense of students' thinking (e.g., Amador et al, 2022;Davis, 1997;Kooloos et al, 2022b;Scheiner, 2023;Sherin & van Es, 2009;Walkoe et al, 2020). One of the most common stances teachers adopt when making sense of students' ideas is the descriptive stance.…”

Development of logical thinking of high school students through a problem-based approach to teaching mathematics

“…Researchers note that an indicator of a high level of metacognition is the correct interpretation of an educational or live problem, the ability to identify appropriate and inappropriate methods of problem-solving, analysis of the solution after the implementation of the chosen strategy. In their work [3] Kooloos et al conclude that logical thinking is a necessary condition for successful mastery of mathematics. The authors of the study note that logical thinking is based on a sequence of mental actionsthe ability to adhere to logical continuity in the expression of judgments and their justification.…”

Research on the Teaching Design Ability of Mathematics Normal Students in Local Normal Universities in China

“…Teachers are required to rethink the mathematical content and their own mathematical thinking process in order to help students construct mathematical thinking [12]. This means that teachers should reflect in teaching, because only in reflection can they develop, so as to provide new learning methods for their growth.…”
