The Role of Tools and Bodily Activity in Mathematical Learning and What
This Suggests for Characterizations of Knowing
Abstract
As part of a larger study investigating students' learning about central
ideas and methods in dynamical systems, I examine how tool use and bodily
activity combine in mathematical learning and how this combination suggests
an alternative characterization to knowing. Through examination of a series
of open-ended interviews with three undergraduate students in differential
equations as they work with a physical tool called the "water wheel", I
elaborate on a form of knowing referred to as knowing-with that is different
than knowing-how and knowing-that. In relation to knowing-with, I highlight
qualitatively different forms of being the tool that contribute to developing
particular views and sensitivities to important mathematical ideas. As
such, knowing-with appears to be an essential and often neglected aspect
of emerging fluencies with tools and ideas in mathematics education. Finally,
I illustrate how the construct of knowing-with is useful for characterizing
students^Y experience with symbolic tools, like rate of change for example,
as well as with physical tools like the water wheel.
