A number of key graduate outcomes related to industry-based interventions and work-industry-related activities (WIA's) are specified by the Swedish Higher Education Ordinance for all Engineering Degree Programmes. A paucity of research regarding student perceptions of these WIAs and their role in student's motivation for learning motivates the current study. Understanding student perceptions of WIA is critical to ensuring the effective integration of WIAs into engineering education. This study explores the perceived motivational effects of WIAs with which students engage through the lens of self-determination theory. Semi-structured interviews were conducted with nineteen master's students studying in two research-intensive Swedish universities. Six themes emerged from thematic analysis. The themes describe the impact WIAs can have on student motivation in terms of their perceptions of (1) relevance for the development of knowledge and skills, (2) influence on the student's future profession identity, (3) utility for gaining industrial experience, inclusive of research experience, (4) relevance to student's programmes of study, (5) industry marketisation agendas, and (6) alignment with industry needs over the student's own needs. The motivating and demotivating aspects of WIA's based on these themes are discussed to improve the collaboration between industry and academia in engineering education.
