Interface creation and redesign techniques in collaborative learning scenarios

User interfaces are redesigned for various purposes, like adapting interfaces or meeting new requirements during software creation processes. In the context of learning systems, the aim of interface redesign is to let the student creates his or her own interface corresponding to the abstract concept to be learned, which is reflected in the interface designed. In this article we present an approach to interface redesign in a cooperative learning scenario for cryptographic protocols. We describe an iterative workflow using two different pieces of software for the creation and redesign of interfaces and distributed simulation and evaluate this approach.
