The embodied, proceptual, and formal worlds in the context of functions
Christou, Constantinos; Pitta-Pantazi, Demetra; Souyoul, A.; Zachariades, Theodosis (2005)In this study we use Tall et al.’s (2000) theory on mathematical concept development, which describes three worlds of operations, the embodied, the proceptual and the formal (Tall, 2004; Tall, 2003; Watson, Spirou, & Tall, ...

Geometric and algebraic approaches in the concept of "limit" and the impact of the "didactic contract"
Elia, Iliada; Gagatsis, Athanasios; Panaoura, Areti; Zachariades, Theodosis; Zoulinaki, Fotini (2009)The present study explores students’ abilities in conversions between geometric and algebraic representations, in problem- solving situations involving the concept of “limit” and the interrelation of these abilities with ...

Reflective, systemic and analytic thinking in real numbers
Zachariades, Theodosis; Christou, Constantinos; Pitta-Pantazi, Demetra (2012)The aim of this paper is to propose a theoretical model to analyze prospective teachers' reasoning and knowledge of real numbers, and to provide an empirical verification of it. The model is based on Sierpinska's theory ...

Student perspectives on the relationship between a curve and its tangent in the transition from Euclidean Geometry to Analysis
Bizza, Irene; Christou, Constantinos; Zachariades, Theodosis (Routledge, 2008)The tangent line is a central concept in many mathematics and science courses. In this paper we describe a model of students' thinking - concept images as well as ability in symbolic manipulation - about the tangent line ...
