“…This study found that participants observed and understood that complex childhood trauma impacted upon children's behavior and learning, congruent with previous research (Davis et al, 2018;Berger, 2019;Berger and Samuel, 2020;Collier et al, 2020;Wall, 2020). In this study, participants' accounts of their experiences touched on how they understood complex childhood trauma as manifesting in both externalizing and internalizing behaviors (Doll, 2019;Splett et al, 2019;Olivier et al, 2020;Miller and Berger, 2021), and they identified that lower academic achievement required differentiation in teaching (Deunk et al, 2018;Smale-Jacobse et al, 2019;Miller and Berger, 2021).…”
