Jitendra, Asha K.; Dupuis, Danielle N.; Star, Jon R.; Rodriguez, Michael C. – Journal of Learning Disabilities, 2016
This study examined the effect of schema-based instruction (SBI) on the proportional problem-solving performance of students with mathematics difficulties only (MD) and students with mathematics and reading difficulties (MDRD). Specifically, we examined the responsiveness of 260 seventh grade students identified as MD or MDRD to a 6-week treatment…
