Accounting for Students' Schemes in the Development of a Graphical Process for Solving Polynomial Inequalities in Instrumented Activity
Rivera, Ferdinand D.
Educational Studies in Mathematics, v65 n3 p281-307 Jul 2007
This paper provides an instrumental account of precalculus students' graphical process for solving polynomial inequalities. It is carried out in terms of the students' instrumental schemes as mediated by handheld graphing calculators and in cooperation with their classmates in a classroom setting. The ethnographic narrative relays an instrumental sociogenetic account of mathematical knowledge construction and foregrounds a progressive evolution of mathematical knowledge from the concrete to the abstract phase.
