“…This framework differs from business-as-usual classroom instruction by remediating delayed skills (e.g., whole-number knowledge) to consolidate the fundamental knowledge necessary for success on the intervention's targeted skills (e.g., fractions knowledge); by incorporating instructional design to compensate for at-risk students' limitations in linguistic, cognitive, or socioemotional processing (e.g., using clear, direct language; relying on worked examples; increasing motivation, on-task behavior, and persistence in the face of academic challenge); and by providing smaller group size to ensure many opportunities to respond and receive corrective feedback (Fuchs, Fuchs, & Malone, 2017;Gersten et al, 2008). Most classroom instruction lacks these features (Doabler, Fien, Nelson, & Baker, 2012;Sood & Jitendra, 2007), without which the academic progress of at-risk students suffers (Kroesenbergen & Van Luit, 2003).…”
