    An exploratory analysis of Early Adopters in education innovations by Lindsey Devers Basileo, Merewyn Elizabeth Lyons

    Published 2024-12-01
    “…Design/methodology/approach – Using Diffusion of Innovation theory (Rogers, 2003) and Self-Determination theory (Ryan and Deci, 2017), data from two surveys (n = 568; n = 108) and qualitative follow-up interviews of Early Adopter teachers (n = 16) were triangulated to discern relationships among their identification as Early Adopters, satisfaction of their basic psychological needs (BPN) and their implementation of an educational innovation. …”
