The paper introduces an evaluation approach for learning systems, which is applicable but not limited to e-learning systems. A discussion of current customs in evaluating learning processes reveals some weaknesses of current (not only e-) learning systems, making sophisticated evaluation technologies unsuitable. To overcome these weaknesses, the authors introduced a storyboard concept to represent a learning system’s didactic design. This way the subject of evaluation becomes explicit and, thus, assessable to validation technologies. The evaluation approach based on the storyboard concept allows both the communication of general assessments about the system’s validity and the indication of the particular weaknesses in the system.
