This study explores how six doctoral engineering students’ identities and motivations evolve through participation in a Graduate Research Group (GRG) researching AI-related engineering (AI engineering) for cyber manufacturing applications at a private Northeastern university and public Southeastern university through a center grant. Using Identity-Based Motivation (IBM) theory, which includes Action Readiness, Dynamic Construction, and Interpretation of Difficulty, this research examines the interplay of subthemes related to these three components of IBM within an interdisciplinary graduate research environment.
Thematic analysis of narratives revealed how graduate student participants’ sense of purpose drove them to take action to engage in graduate research, which was continually shaped by interdisciplinary collaboration. Similarly, their identities were seen to be dynamically constructed as they transitioned from learners to contributors or leaders as they developed a sense of belonging within the research group consistent with IBM theory. Moreover, the students interpreted challenges as opportunities for growth, strengthening their determination to solve research problems.
The relationships between the subthemes revealed an interconnectedness between the three IBM components. The graduate students’ responses reflected a reinforcing cycle, where purpose-driven actions influenced identity development, shaping how difficulties were perceived and addressed. Emerging findings further highlight the importance of supportive, interdisciplinary research environments in fostering graduate students’ identities and motivations.
