ABSTRACT
This chapter describes the basic mindset underlying implementation and spread in educational design research on any scale: planning for actual use. Thereafter, implementation is described in terms of adopting, enacting, and sustaining interventions. The chapter offers some considerations for designing interventions for actual use within educational design research projects. It describes implementation and spread and emphasizes its links with the three main phases. The chapter aims to support educational design researchers in attending to implementation and spread during each main phase. The terms fidelity and integrity are often used to describe how the planned processes are enacted during implementation. The strategies used for facilitating implementation and spread can be powerful in shaping the uptake and use of interventions. Reducing implementation challenges by altering contextual factors not only creates a larger shift hurdle, it also sacrifices some of the ecological validity of the findings.
