Recent debates on powerful teaching practices pinpoint the importance of cognitively demanding, higher-order student assignments. Educational researchers have developed complex, domain-specific systems for categorizing the cognitive demand of large scale test items. However, most of these extensive, domain-specific taxonomies are scientific tools but they are not very useful for teachers' daily job and teacher education. We therefore developed a clear and modest taxonomy for analyzing the cognitive level of student assignments or assessment tasks across all subjects. Our work is based on Bloom's revised taxonomy of educational objectives and some core features of powerful teaching practices.
