Evidence based reading instruction and intervention are essential for students with disabilities. The authors recommend that elementary special education teachers emphasize both code-based and meaning-based skills as part of delivering intensive reading interventions, including providing explicit and systematic decoding and vocabulary instruction.…

A proposed avenue for increasing students' vocabulary knowledge and reading comprehension is instruction that promotes students' enthusiasm and attention to words, referred to as "word consciousness". This study seeks to investigate, at the utterance level, whether and how word consciousness talk is used in classrooms with young word…

Based on its coincidence with a significant period in language development for children, preschool provides a favorable setting to foster vocabulary growth. The purpose of this study was to evaluate the effectiveness of two instructional conditions and an incidental exposure condition for teaching targeted vocabulary words to preschool students…

In this experimental study, we examined the effects of a technology-mediated intervention to improve students' understanding of academic vocabulary and its impact on measures of vocabulary and comprehension. The Vocabulators program was implemented in two states involving 24 teachers and 200 third-grade students identified as in need of…

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…

There is a growing need for the inclusion of direct, explicit vocabulary instruction in the early elementary grades. Young children are entering school with a wide range of early literacy experiences, including vocabulary knowledge. Those students who are limited in their vocabulary knowledge are at a greater risk for later language and reading…

We examined data from an 18-week kindergarten vocabulary intervention study to determine whether treatment outcomes had differential effects that favored English language learners (ELLs) or English-only learners (EOLs) and whether the relationship between initial English general receptive vocabulary knowledge and response to vocabulary…

Two approaches to systematic word review were integrated into an 18-week program of extended vocabulary instruction with kindergarten students from three high-need urban schools. Words in the embedded and semantically related review conditions received systematic and distributed review. In the embedded review condition, brief word definitions were…

The purpose of this study was to evaluate effectiveness of rich and basic instruction to incidental exposure of target words with first-grade students within the context of repeated shared storybook reading. Participants were 224 first-grade students, randomly assigned to a condition by classroom, from three elementary schools that serve large…

The purpose of this study was to compare 2 methods for directly teaching word meanings to kindergarten students within storybook read-alouds that varied in instructional time and depth of instruction along with a control condition that provided students with incidental exposure to target words. Embedded instruction introduces target word meanings…

The purpose of the two studies reported in this article was to evaluate the effectiveness of extended vocabulary instruction during storybook reading with kindergarten students within a small-group intervention setting. Extended vocabulary instruction is characterized by explicit teaching that includes both contextual and definitional information,…
