Marina Milner-Bolotin is an Associate Professor in science education in the Faculty of Education at the University of British Columbia, Vancouver, Canada. She holds a M.Sc. in theoretical physics from the Kharkov National University in Ukraine. She also holds M.A. and Ph.D. degrees in mathematics and science education from the University of Texas at Austin in 2001. At UT Austin, she investigated how project-based instruction in physics courses for future elementary teachers affected their interest in science and their ability to do and teach science. She specializes in science and mathematics education and science outreach. She studies how technology can be used in teacher education to prepare mathematics and science teachers who will be able to engage 21^st century students in meaningful learning. Her work has appeared in international peer-reviewed research journals, scientific books, conference proceedings, seminars, and workshops. Since 1993, she has been teaching science and mathematics in Israel, USA, China, and Canada to elementary students to university undergraduates in science programs, and to pre-service and in-service teachers. She has led many professional development activities for science in-service and pre-service teachers and university faculty. She is an author of an introductory physics textbook used by thousands of students. Before joining UBC, she was faculty member at Ryerson University in Toronto, Ontario. She has received numerous research and teaching awards and served on the Executive Board of Canadian and International science education associations.

Yifat Ben David Kolikant is an Associate Professor in the Seymor Fox School of Education, Hebrew University of Jerusalem. Her academic work is devoted to theorizing learning, teaching, and schooling in the age of globalization and digitalism, an age characterized by the ubiquity of digital technology, an information explosion, pluralism, and rapid changes. Over the past few years, she has dealt with two core questions: (a) How does digital technology influence schooling and (b) how can effective teaching environments be characterized? In recent years she has been involved in several studies aimed at understanding and enhancing in-service teacher learning under conditions of dramatic curricular and policy changes, and the role that ICT plays and should play in it. Prof. Ben-David Kolikant holds a Ph.D. degree in science teaching from the Weizmann Institute of Science, received in 2002.

Dragana Martinovic is a Professor of Mathematics Education at University of Windsor, where she leads the Human Development Technologies Research Group. Dragana is a Fellow of the Fields Institute for Research in Mathematical Sciences and a Co-Director of the Fields Centre for Mathematics Education. She is a recipient of the Excellence in Mentoring Award at University of Windsor. In her research, Dr. Martinovic explores ways in which technology can improve teaching and learning outcomes, and the digital literacy skills needed for a successful learner and worker of the 21^st century. She is dedicated to supporting teacher-led research and providing opportunities for all involved in education to collaboratively work towards increasing student engagement, success, and love for learning mathematics. Dragana is on the Executive for the Mathematics Knowledge Network, hosted by the Fields Centre for Mathematics Education. She co-chairs the Mathematics Leadership Community of Practice (since 2016) and the Fields Cognitive Science Network for Empirical Study of Mathematics and How it is Learned, and is a founding and current co-editor of the Springer book series, Mathematics Education in the Digital Era.
