We evaluated the long-term effects of a supplemental, small-group kindergarten vocabulary intervention in fall and spring of first grade and winter of second grade. Participants included students from two studies, an initial efficacy study and a subsequent replication study, identified as at risk for language and learning difficulties, who were…

The purpose of the current study was to examine the influence of L1 (i.e. Spanish) receptive vocabulary on both expressive and receptive knowledge of target vocabulary words taught through L2 (i.e. English) instruction and intervention. Participants were Bilingual US kindergarten students determined to be at-risk based on English receptive…

We evaluated the impact of a supplemental, small-group kindergarten vocabulary intervention designed to reinforce content taught in core classroom instruction implemented within a multitiered system of support (MTSS) framework. Kindergarten teachers implemented a published vocabulary program with all their students during whole-class instruction…

The present study examines an ecological model for intervention use to explain student vocabulary performance in a multi-tiered intervention setting. A teacher self-report measure composed of factors hypothesized to influence intervention use at multiple levels (i.e., individual, intervention, and system level) was administered to 54 teachers and…

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…

This study examined the predictive validity of formative assessments embedded in a Tier 2 intervention curriculum for kindergarten students identified as at risk for reading difficulty. We examined when (i.e., months during the school year) measures could predict reading outcomes gathered at the end of kindergarten and whether the predictive…

Teachers may feel uncertain about how to ensure that all students, including students with identified disabilities, those at risk for learning disabilities, and English learners, achieve the Common Core State Standards (CCSS) in vocabulary. At the same time, they are also searching for practical, concrete ideas for incorporating the CCSS in the…

This article provides suggestions for teachers and practitioners on vocabulary activities that can help kindergarteners attain the vocabulary standards proposed by the Common Core State Standards (CCSS). The activities and examples included in the paper stem from an efficacy study I recently conducted with Dr. Michael Coyne and colleagues with…

The current study examined a solution to high false positive reading risk classification rates in early kindergarten by investigating a method of identifying students with possible false positive risk classifications and returning them to general classroom instruction. Researchers assessed kindergarten students (N = 105) identified as at risk who…

This study examined the changing role and longitudinal predictive validity of curriculum-embedded progress-monitoring measures (CEMs ) for kindergarten students receiving Tier 2 intervention and identified as at risk of developing reading difficulties. Multiple measures were examined to determine whether they could predict comprehensive latent…

This longitudinal study examined (a) the second-grade reading outcomes of 368 children who participated in either experimental or school-designed supplemental intervention in kindergarten, and (b) the influence and interactions of learner variables and type of intervention on reading achievement. Descriptive findings indicated that percentages of…

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…

This study examined the predictive validity of combinations of progress-monitoring measures: (a) curriculum-embedded phonemic awareness and alphabetic/decoding measures, and (b) Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2002) nonsense word fluency and phoneme segmentation fluency on reading outcomes of…

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…
