abstract={A Genetic Decomposition (GD) is developed in this paper, in terms of the APOS instructional treatment of mathematics, for teaching and learning the polar coordinates. The design of the GD is based on the conclusions obtained by a written test and by oral interviews performed on a group of students of the Physics Department of the University of Neyshabur, Iran.},
