Complex instruction is a pedagogical approach that enables students to learn and teachers to teach at a high intellectual level in academically, linguistically, racially, ethnically, and socially heterogeneous classrooms.
Complex Instruction evolved from over 20 years of research by Elizabeth Cohen, Rachel Lotan, and their colleagues at the Stanford School of Education. The goal of this instruction is to provide academic access and success for all students in heterogeneous classrooms.
