“…To explain reduced achievement gaps between ethnicity/race groups, other researchers have pointed to social-psychological variables in their intervention research. Studies on these interventions reported reducing achievement gaps between ethnicity/race groups using a series of brief writing exercises designed to help students affirm their values (Cohen, Garcia, Apfel, & Master, 2006;Hanselman, Bruch, Gamoran, & Borman, 2014) and feel a stronger sense of belonging (Shnabel, Purdie-Vaughns, Cook, Garcia, & Cohen, 2013). Though speculative, it seems plausible that SI might contribute to students' sense of belonging, because SI provides opportunities for students to work collaboratively in small groups and interact with a peer model (i.e., the SI leader).…”
