Professor Yüksel Dede is a faculty member at the Department of Mathematics Education at Gazi University, Turkey. He worked at Berlin Freie University in Germany with the Alexander von Humboldt [Av H] Scholarship and the Scientific and Technological Research Council of Turkey [TUBITAK] Scholarship. He has worked as a director, expert, or consultant in projects supported by various public institutions in Turkey (TUBITAK, Governorships, Governorates, Provincial Directorates of National Education) and abroad (Av H-Berlin Freie University, Germany; Monash University, Australia; Korea University, South Korea). He is also on the editorial board of refereed national and international journals,  and has published journal articles, book chapters, translated book chapters, and conference proceedings nationally and internationally. His research interests include the affective domain in mathematics education, especially values education, the teaching of mathematics concepts (e.g., algebrateaching), mathematics teacher education, international comparative studies, research methods, and the application of advanced statistical techniques in mathematics education.   Dr Gosia Marschall is an Assistant Professor in Teacher Professional Learning at the University of Cambridge, United Kingdom. Her main research agenda and interests relate to teacher professional learning, conceptualized from a holistic perspective (paying particular attention to teacher self-efficacy, affect, teacher identity and aspects of human functioning and self-regulation). Her research work is predominantly abductive and phenomenological, focusing on theory-building and theory-advancing ideas. She is currently working on projects concerning the relationship between mathematics teachers” professional identity and the development of knowledge and skills for teaching; theorizing in teacher professional learning; teacher decision making; and values in mathematics education.     Professor Philip Clarkson is an emeritus professor at Australian Catholic University, Australia, where he worked for 28 years, and honorary fellow at the University of Melbourne, Australia. He spent nearly five years in the early 1980s as the director of a Research Centre at the Papua New Guinea University of Technology. Prior to that, he taught at Monash University and tertiary colleges in Melbourne. He began his professional life as a teacher of chemistry, environmental science, mathematics, and physical education in secondary schools. Philip has led major consultancies and Australian Research Council (ARC) research projects,  and was the president, secretary, and vice president (Publications) of the Mathematics Education Research Group of Australasia (MERGA).
