Making a circle: Tool use and the spaces where we live. (English)
Cogn. Instr. 24, No. 4, 387-437 (2006).
Summary: A group of high school students created a drawing of a circle using a device called the Drawing Machine. To describe their experiences, we propose an alternative to the idea that to master a tool one must create a mental version of the tool. We suggest, instead, that as students change their relationships to a tool over time, their lived-in spaces change. Drawing on studies of practice, we explore the roles of past experience, planning, and communication in the development of students’ lived-in spaces as they increase their competence with the tool and with the mathematics of drawing a circle.
