“…Beginning with Engeström's first question of who the learning participants in movements are, the research studies in our review focused on the learning of members (e.g., Martin, 1988;Vea;, whom we identified as activists who organise the movement, participants (e.g., Lee 1993;Ollis & Hamel-Green, 2015), whom we identified as people who join the movement, and finally the public who observe the movement from the outside. Few scholars (e.g., Church et al, 2016;Díez-Gutiérrez & Díaz-Nafría, 2018;Roy, 2012) have considered the public in terms of SML research. When they have considered the public, it has been in the form of visitors or the audience of social justice events such as film festivals.…”
