In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

Using a nationally representative sample of dual language learners (DLLs) attending Head Start, this study investigated how the language used for instruction and the proportion of DLLs in the class was associated with English and Spanish receptive vocabulary development between the fall and spring (n = 531). Based on teacher report of the language…
