Different Skills? Identifying Differentially Effective Teachers of English Language Learners

This report presents an analysis of teacher characteristics and learning experiences and describes how they can affect English language learner (ELL) student outcomes in mathematics. Teachers with prior experience teaching ELL students and teachers who pursued specific training in ELL instructional strategies achieved positive gains with their ELL mathematics students when compared with non-ELL students. Teachers with years of generic teaching experience did not achieve similar gains.
