Dual language learner children (DLLs) benefit from early childhood education (ECE) and learning multiple languages, but research has predominantly focused on English monolingual children, with limited insight on the ECE and early development of DLLs. This study investigated whether DLLs' developmental assets assessed at pre-k entry (i.e. English…

Few studies have considered academic vocabulary interventions for students who have learning disabilities (LD) and also are English learners (EL).
