The aim of this presentation is to share the successes and challenges that we have experienced, as an international community of researchers, running formative interventions in online research environments. We will consider lessons learned from six projects focused on interventions in diverse educational settings: 1) part-time adult learners working in facilities management, who were unhappy with online teaching and learning for the professional diploma courses they were undertaking; 2) K-6 school personnel seeking to create models, with which they aspired to tackle inequalities in accessing education; 3) post-compulsory education providers seeking to engage community stakeholders, in a particularly disadvantaged area with poor educational outcomes; 4) staff in a specialist school for blind students designing a model of inclusive practice, to respond to the changing nature of the student profile in their local community; 5) online educators in Higher Education Institutions, seeking to understand their own professional development needs; and 6) doctoral students from a range of disciplines, working alongside a multinational corporation to scope systemic and social challenges, developing an inclusive environment for neurodiverse employees to prosper. By sharing our successes and challenges, we will contribute to existing knowledge about the various methodologies we used to design and conduct these diverse projects, so as to continue to build collaboration in the use of formative interventions by the wider international research community.
