Interactive book reading (IBR) has proven effective for increasing children's lexicons with most of the results based on students' learning of nouns. Little is known about the application of IBR to instructional verbs (i.e., words used during the instruction of academic content). To address this gap, 122 prekindergarten children were recruited…

We investigated whether individual differences in overall receptive vocabulary knowledge measured at the beginning of the year moderated the effects of a kindergarten vocabulary intervention that supplemented classroom vocabulary instruction. We also examined whether moderation would offset the benefits of providing Tier-2 vocabulary intervention…

This study investigated: 1) the influence of alphabet instructional content (letter names, letter sounds, or both) on alphabet learning and engagement of English only and dual language learner (DLL) children, and 2) the relation between children's initial status and growth in three underlying cognitive learning processes (paired-associate,…

This study examines whether explicit reading comprehension instruction is relevant for students with high-functioning autism spectrum disorder (ASD). Forty-five students (M[subscript age] = 9 years) were randomly assigned to two conditions: control or intervention. Those assigned to the intervention condition received instruction on vocabulary,…

This study examined the efficacy of using different types of mobile media apps to increase the receptive and expressive vocabulary development of 3-, 4-, and 5-year-old preschool children living in economically disadvantaged communities. Children and teachers in four Head Start classrooms participated in the quasi-experimental study, which…

With the emergence of electronic media over the past two decades, young children have been found to have increased exposure to video games, computer-based activities, and electronic books (e-books). This study explores how exposure to animated ebooks impacts young children's literacy development. A stratified convenience sample (n = 24) was…

The ability to flexibly approach the pronunciation of unknown words, or set "for variability", has been shown to contribute to word recognition skills. However, this is the first study that has attempted to teach students strategies for increasing their set for variability. Beginning readers (N = 15) were instructed to correct oral…

The purpose of this study was to determine the extent to which tri-weekly evidence-based vocabulary lessons implemented throughout the regular school day would increase kindergarten students' expressive and receptive vocabulary development, thus decreasing the vocabulary gap exhibited between low-income children and their more advantaged peers…

Broad-stroke approaches to vocabulary teaching in preschool include effective instructional elements, yet may be too ill-structured to affect the vocabulary learning of children experiencing serious delays. Using a formative research approach, this study examines the design potential of a supplemental vocabulary instruction technique that…

The present study examined the cognitive factors that influence children's physical science learning from a multimedia instruction. Using a causally coherent text and visual models, we taught 4th- and 7th-grade children about the observable and molecular properties of the three states of water. We manipulated whether the text was read by a tutor…

The purpose of this study was to investigate the response of kindergarten students at-risk for reading failure to a two-tiered vocabulary intervention delivered in the context of a shared storybook reading activity employing rich and robust vocabulary instruction. Rich vocabulary instruction is defined as explicit vocabulary instruction in which…
