This article presents an overview of Project ELEECT (English Learners’ Educational Excellence Capitol Teacher Training Project), a U.S. Department of Education-funded program designed to prepare teachers in Culturally and Linguistically Responsive Pedagogy (CLRP) for multilingual learners (ML). The purpose of Project ELEECT is to promote educational justice for MLs by revising a Master of Arts + ESL Licensure program for pre-service teachers and creating a professional development program for in-service teachers. It prepares pre-service and in-service teachers of MLs in CLRP through teacher research, and specifically offers a novel professional learning tool, which we call Impact on Learning Studies (IOLS). This teacher research tool represents a framework for the systematic and intentional self-study of their teaching practices. In this article, we lay the foundations for a research agenda that investigates pre-service and in-service teachers’ understanding and implementation of CLRP, documents concrete examples of CLRP in various classroom contexts, and examines the efficacy of teacher research initiatives to prepare teachers in CLRP. Project ELEECT prepares teachers to invite students’ cultural and linguistic experiences into their classrooms, create spaces for CLRP, and foster critical consciousness in learning settings, thus taking a major shift towards cultivation of anti-racist dispositions in education.
