A recent approach to support authors is to compute several structural measures of the domain model to estimate its adaptivity degree. However, our empirical results of eight different courses and more than 1300 users suggest that subjective adaptivity success and structural adaptivity degree are not related. We argue, that the adaptivity degree is an inherent property of the content and does not imply adaptation quality.enText/Conference Paper
