Cornelia S. Große works in the domain of Educational Psychology and investigates topics of learning and instruction. She studied Psychology at the Albert-Ludwigs Universität, Freiburg, Germany, and received her Diploma in 2001. She continued working there with Alexander Renkl and finished her doctorate on learning with multiple solution methods in 2004. From 2005 to 2009 she worked as a lecturer in the field of educational diagnostics at the University of Bremen, Germany, followed by a postdoc position funded by the University of Bremen (2010-2011) where she continued working on learning with multiple solution methods. From 2012 to 2016 she investigated ways to foster competencies in mathematical modeling as PI in a DFG project. Since 2016, she has worked with Rolf Drechsler at the University of Bremen. Current research topics are cognitive processes in learning, learning with worked examples, and the acquisition of competencies in mathematics and computer science.

Rolf Drechsler received his Diploma and Dr. phil. nat. degrees in Computer Science from the Goethe-Universität Frankfurt am Main, Germany, in 1992 and 1995, respectively. He worked at the Institute of Computer Science, Albert-Ludwigs Universität, Freiburg, Germany, from 1995 to 2000, and at the Corporate Technology Department, Siemens AG, Munich, Germany, from 2000 to 2001. Since 2001, Rolf Drechsler has been a Full Professor and Head of the Group of Computer Architecture, Institute of Computer Science, at the University of Bremen, Germany. In 2011, he additionally became the Director of the Cyber-Physical Systems Group at the German Research Center for Artificial Intelligence (DFKI) in Bremen. His current research interests include the development and design of data structures and algorithms with a focus on circuit and system design. He is an IEEE Fellow.
