Education is characterized by at least the following features: (1) it offers learning environments that help students to achieve preset goals; (2) it induces learners to engage in relevant learning tasks; and (3) it offers support while learners execute learning tasks. Offering learning environments builds on the assumption that learners will actually engage in the learning tasks and use the support provided. There is, however, growing evidence, that in a lot of cases students do not comply with that assumption. By not engaging as expected in the learning tasks and/or by not (adequately) using the support, learners reveal the phenomenon of what could be called--at least from the perspective of the (designer of the) learning environment--'instructional disobedience'. 'Instructional disobedience' occurs when learners do not act as expected from them in a learning environment. While the literature has already referred to faulty assumptions and specified conditions for the effectiveness of instructional interventions, it seems the phenomenon of instructional disobedience has not yet attracted systematic research attention. In this contribution, we want therefore further unravel the nature and relevance of the phenomenon. This is done by analyzing the occurrence of instructional disobedience, possible explanations and ways to deal with it. As a start we illustrate the phenomenon by providing some examples.
