Research Interests His research in mathematics education can be divided mainly into four areas: cognitive development of mathematical concepts and mental representations, ICT integration in mathematics teaching, problem solving and 3D geometry thinking.

Cognitive development of mathematical concepts and mental representations He investigated the development of mathematical concepts under various theoretical lenses. He used Tall’s theory in collaboration with other colleagues to analyse students’ understanding of function (Christou, Pitta-Pantazi, Soyoul, & Zachariades, 2005). He also investigated students’ levels of understanding of exponents by using elements of the conceptual change theory and the property oriented view (Pitta-Pantazi, Christou, & Zachariades, 2007). More recently he shifted his research focus from mental representations to students’ cognitive styles.

Specifically, he investigated the effect of students’ cognitive styles on students’ performance in measurement and geometry tasks in a dynamic geometry learning environment (Pitta-Pantazi, & Christou, 2007, 2008). He has also examined students’ inductive reasoning by proposing a model that hypothesizes that six distinct cognitive processes aiming at detecting similarity and/or differences in attributes and relations are used for the solution of inductive mathematics problems dealing with attributes or relationships (Papageorgiou & Christou, 2007).

Integration of ICT in mathematics teaching He has studied extensively the integration of ICT in mathematics teaching and specifically how students’ interactions with technological tools mediate the construction of mathematical meanings. In Christou, Mousoulides, Pittalis and Pitta (2004, 2005) he has explored problem solving and problem posing in a dynamic geometry environment and how prospective teachers can teach proofs through exploration in dynamic geometry environments. He has also worked on the theoretical considerations of developing a 3DMath dynamic geometry software (Christou, Pittalis, Mousoulides, & Jones, 2007).

Problem Solving Significant domain of his research activity is mathematical problem solving. He has searched for ways in which students constructed meanings through mathematical problem solving and how students – teacher – tools interactions mediate the construction of these meanings. He has studied and proposed a theoretical model for describing the cognitive processes involved in mathematical problem solving and problem posing (Christou, Mousoulides, Pittalis & Pitta, 2005) related to mathematical modeling as a venue for developing students’ problem solving abilities. Another parameter of his research activity is the emergence of modeling perspectives from the genre of problem solving research (Mousoulides, Sriraman, Christou, 2008). He explored students’ mathematical and modeling developments as

he worked with his team on complex modeling problems using technological tools, involving interpreting and dealing with multiple sets of data.

3D geometry thinking Recently he has examined with his team the structure of 3D geometry thinking by identifying different types of reasoning in 3D geometry thinking and its relation with spatial ability. Based on research results we proposed a model assuming that four types of reasoning are involved in 3D geometry thinking: (a) the type of reasoning that refers to the representation of 3D objects, (b) the type of reasoning that refers to spatial structuring, (c) the type of reasoning that refers to the conceptualization of mathematical properties and (d) the measurement reasoning (Pittalis, Mousoulides & Christou, 2007).
