A. Procedure In order to address these questions, we ran a three year long qualitative study with students with mild and moderate intellectual disability and their educators, using games in different educational settings. In the first phase of the study (T1) that lasted for 15 months each, different games and different empirical tools such as focus groups, and participant observation were used, in order to gather initial information and document possible change in the experience of the students as well as in students’ self-determination, engagement and motivation. We also used the STD, Perceived Competence Scale (PCS) questionnaire in the form of closed interviews with students.
