The aim of this symposium 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 a range of projects focused on interventions in diverse educational settings. 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, also when an online design is used in formative interventions to reach for change and reach out to participants.
