Preschool is a critical time in children’s oral language and pre-literacy skill development, but this development varies greatly among children. Those with smaller vocabularies are at greater risk for developing future language and reading difficulties that persist throughout their education. Because vocabulary knowledge is essential for later reading success, early instruction in preschool is key. To better understand how to enhance preschoolers’ word learning, the current dissertation contains three studies that examined the benefits of explicit vocabulary instruction and identified the factors that best facilitated vocabulary learning among a diverse group of young children. To aid in the early identification …

Effects Of A Spanish Phonological Awareness Intervention On Latino Preschoolers' Dual Language Emergent Literacy Skills, Xigrid T. Soto
