Christou Constantinos


Constantinos Christou is professor of mathematics education at the University of Cyprus. He is the president of the Governing Body of the Open University of Cyprus. Constantinos Christou served as the president of Cyprus Council for the Recognition of Higher Education Qualifications (Ky.S.A.T.S), vice president of the Accreditation Council of Cyprus (S.Ek.A.P) and President of the Cyprus Scientific Council.He was an elected member of the board of “European Society for Research in Mathematics Education”. He was appointed as the coordinator of the committee for the development of new mathematics curricula in Cyprus and the new teaching material. He has published more than 100 books, book chapters, journal articles and conference proceedings. He is a reviewer of scientific journals in mathematics education. He participated as coordinator and partner in four European research projects and was the coordinator of five other research projects funded by the University of Cyprus, the Cyprus Research Foundation and Leventis Foundation. He was the National Representative of Cyprus in the TIMSS 2003 research study and PISA 2012. He participates in the European project KeyCoMath.

Research Interest

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.(a) Cognitive development of mathematical concepts and mental representations. He investigated the development of mathematical concepts under various theoretical lenses. (b) 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. (c)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 related to mathematical modeling as a venue for developing students’ problem solving abilities. (d) 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.
