'Programa de Especialização Docente Brasil' (PED Brasil) is a learning and professional development program in mathematics or science education for primary or secondary in-service schoolteachers. Designed to be a teacher education program that addresses issues related to educational quality and equity in racially, socially, and academically diverse Brazilian schools, PED Brasil intended to craft a program with a signature pedagogy that could be capable of shaping the ways of thinking and acting in the teaching profession. PED Brasil does it by integrating different dimensions of knowledge and demonstrating various aspects of professional practice, considering the democratic society we aim to build. In this paper, we analyse how PED Brasil has adopted Complex Instruction as its signature pedagogy.
