Alison Clark-Wilson is a Principal Research Fellow at UCL Institute of Education, London, United Kingdom. Alison’s research spans aspects of designing, implementing and evaluating digital technologies for mathematics education. She leads the European Society for Research in Mathematics Education’s working group on "teaching mathematics with technology and other resources".Ana Donevska-Todorova earned her PhD at the Institute of Mathematics at the Humboldt-University of Berlin and now works in the research field of meaningful design, application and dissemination of digital resources for teaching and learning mathematics. She is fully engaged with the activities of the European Society for Research in Mathematics Education as a member of its International Programme Committee and as a co-leader of the ERME Topic Conferences Mathematics Education in the Digital Age.Eleonora Faggiano is Assistant Professor in Mathematics Education at the University of Bari Aldo Moro, Italy. Her research interests concern the integration of digital and non-digital resources in the teaching practices and mathematics teacher professional development.Jana Trgalova is Associate Professor at Claude Bernard University, France. She is involved in primary and secondary mathematics teacher education and her research focuses on digital technology and resources for mathematics education, their design, appropriation, use and evaluation.Hans-Georg Weigand is Professor at University of Würzburg, Germany. He is interested in the use of digital technologies in mathematics education and teacher education, having authored books on algebra, geometry and computers in mathematics education. He leads the European Society for Research in Mathematics Education’s working group on "learning mathematics with technology and other resources".
