Xun Ge is Professor of Instructional Psychology and Technology and Chair of the Department of Educational Psychology, Jeannine Rainbolt College of Education, the University of Oklahoma. She holds a Ph.D. in Instructional Systems from the Pennsylvania State University. Dr. Ge's primary research interest involves scaffolding students' complex and ill-structured problem solving and selfregulated learning through designing instructional scaffolds, cognitive tools, learning technologies, and open learning environments (including virtual learning community, game-based learning, inquiry-based learning, and problem-based learning). Over the past years, her scholarly works has evolved to link cognition to motivation. Dr. Ge is also interested in studying the impact and assessment of game-based learning in supporting complex, ill-structured problem solving. Dr. Ge has extensive research experience in STEM education, and she has collaborated with scholars from diverse disciplines around the world. Dr. Ge's research has been published in a co-edited book published by Springer, multiple book chapters in some highly regarded books, and numerous articles in many leading journals of the field, not to mention many other conference proceeding papers. Dr. Ge has been recognized for three prestigious awards she has received-2012 Outstanding Journal Article, 2004 Outstanding Journal Article 2003, and Young Scholar awarded by Educational Technology Research & Development and the American Educational Communications and Technology.Dirk Ifenthaler is Professor for Instructional Design and Technology at theUniversity of Mannheim, Germany as well as an Adjunct Professor at Deakin University, Australia. His previous roles include Professor and Director, Centre for Research in Digital Learning at Deakin University, Australia, Manager of Applied Research and Learning Analytics at Open Universities Australia, and Professor for Applied Teaching and Learning Research at the University of Potsdam, Germany. Dirk was a 2012 Fulbright Scholar-in-Residence at the Jeannine Rainbolt College of Education, at the University of Oklahoma, USA. Professor Ifenthaler's research focuses on the intersection of cognitive psychology, educational technology, learning science, data analytics, and computer science. He developed automated and computer-based methodologies for the assessment, analysis, and feedback of graphical and natural language representations, as well as simulation and game environments for teacher education. His research outcomes include numerous co-authored books, book series, book chapters, journal articles, and international conference papers, as well as successful grant funding in Australia, Germany, and USA-see Dirk's website for a full list of scholarly outcomes at www.ifenthaler. info. Professor Ifenthaler is the Editor-in-Chief of the Springer journal Technology, Knowledge and Learning (www.springer.com/10758). Dirk is the Past-President for the AECT Design and Development Division, 2013-2015 Chair for the AERA Special Interest Group Technology, Instruction, Cognition and Learning and Co-Program Chair for the international conference on Cognition and Exploratory Learning in the Digital Age (CELDA).J. Michael Spector is a Professor of Learning Technologies at the University of North Texas. Previously he was a Professor of Educational Psychology and Instructional Technology at the Learning and Performance Support Laboratory at the University of Georgia, Associate Director of the Learning Systems Institute at Florida State University, and Chair of Instructional Design, Development and Evaluation at Syracuse University. Prior to that, he was Director of the Educational Information Science and Technology Research Program at the University of Bergen, and the Senior Scientist for Instructional Systems Research at Armstrong Laboratory. He earned a Ph.D. in Philosophy from The University of Texas at Austin. His research focuses on intelligent support for instructional design, assessing learning in complex domains, and technology integration in education. Dr. Spector served on the International Board of Standards for Training, Performance and Instruction (ibstpi). He is a Past-President of the Association for Educational and Communications Technology and a Past-Chair of the Technology, Instruction, Cognition and Learning Special Interest Group of AERA. He is editor of Educational Technology Research & Development and edited the third and fourth editions of the Handbook of Research on Educational Communications and Technology, as well as the Encyclopedia of Educational Technology.
