“…(p. 3) Research has generated much evidence in support of Bronfenbrenner's theory. For instance, group norms with respect to in-and outgroups were shown to impact the integration and participation of migrant children concerning aspects such as cross-group friendships, collaboration among pupils, the development of prejudice, and discrimination (e.g., Celeste et al, 2016;Eckstein et al, 2021;Gönültaş & Mulvey, 2019;Grütter et al, 2021;Kalkman et al, 2017;Miklikowska, 2017;van Vemde et al, 2021). Studies also point to the central role of teachers in managing diversity and integration (e.g., Grütter et al, 2021) and enhancing adjustment and achievement by fostering (migrant) children's sense of belonging (e.g., Goodenow, 1993;Karakus et al, 2023;Teja & Schonert-Reichl, 2013).…”
