Usability Engineering in Computer Aided Learning Contexts Results from usability tests and questionnaires

This paper describes a process to consolidate observations and findings from usability evaluation phases into a comprehensible list of usability deficiencies as a basis for quality assurance methods. A so called “evidence test” process is transferred from the world of software usability engineering into the context of computer aided learning (CAL) and computer supported cooperative learning (CSCL). It is based on experiences from quality management and evaluation efforts in the German flagship project “VFH” (Virtual University of Applied Sciences in Engineering, Computer Science and Economics) and the project “medin”. The paper is intended as a basis for continued research in the area of usability of computer aided learning, as well as a founded best practice description for practitioners who work in this context.
