This review and case example describes the key components of elementary reading instruction and intervention within multitiered systems of supports (MTSS) and ways to enhance and scaffold reading instruction and intervention for language as a means of supporting the learning of students who are emergent multilingual (EM) learners. First, we provide an overview of elementary reading comprehension skills and describe culturally, linguistically, and ecologically situated learning principles and overview the essential elements of MTSS rooted in these principles. Next, we present research-based practices that enhance reading instruction and intervention among elementary EM students. We then illustrate the PLUSS framework to highlight how educators can implement these practices across MTSS. Finally, we present considerations for reading instruction and intervention and provide resources that may be useful to educators and policymakers with respect to MTSS.

In this cluster randomized control trial study, the authors explored the efficacy of an intervention designed to improve second-grade English learners' knowledge of challenging, high-utility English vocabulary. The authors also examined whether the intervention had a differential effect on content words that differ on two attributes (cognate status and abstractness designation) and whether the effects lasted across time. Within schools, teachers were randomly assigned to treatment or control conditions, resulting in 12 treatment classrooms and 10 control classrooms. Teachers in the treatment condition developed vocabulary using six methods: interactive shared reading, direct instruction of individual words, instruction in cognate use, activities to foster word consciousness and reinforce instructed words, and use of visual and linguistic supports. Teachers in the control condition read the same books with the target vocabulary inserted into the stories. Findings on the curriculum-based and standardized measure of vocabulary indicated that the intervention implemented for four 50-minute lessons per week for 18 weeks was effective in helping English learners acquire challenging high-utility school-relevant vocabulary (Cohen's d = 1.88 for content words; d = 0.41 for connecting words; d = 0.47 for the Test of Oral Language Development). The effects differed by word characteristics, with higher effect sizes for words that are noncognates (d = 1.57 for both concrete and abstract noncognates; d = 1.02 concrete cognates; d = 0.81 for abstract cognates). Ten months after the intervention, treatment students still outperformed control students on content vocabulary learned during the intervention (d = 1.31). This study helps validate a multifaceted approach to vocabulary intervention and research.

This study used a within-subjects design to explore two instructional conditions for developing vocabulary in second-grade Spanish-speaking English learners (ELs)--extended instruction and embedded instruction implemented during shared interactive reading. Words assigned to the extended condition were directly taught using a multifaceted approach that included visuals, bilingual definitions, examples, spelling, and partner-talk about the words' meaning. Words assigned to the embedded condition were taught solely through brief definitions to embedded text, writing activities, and songs. In the control condition students heard the target words read aloud during shared interactive reading but without definitions or direct instruction. The study also explored the interaction between instructional condition and word type. Four types of words--abstract cognates, abstract noncognates, concrete cognates, and concrete noncognates--were randomly assigned to each condition. Nine teachers in four schools and 187 second-grade ELs participated in this within-subjects intervention, which took place in transitional bilingual classrooms. Findings indicated that across all word types, both extended and embedded instruction were more effective than the control condition in helping ELs acquire vocabulary. Findings also indicated that extended instruction was more effective then embedded instruction for all word types except concrete cognates suggesting that these young Spanish-speaking ELs were advantaged by word knowledge in their home language. Finally, while embedded instruction was less effective than extended instruction, it was much more effective than a control condition. Embedded instruction takes significantly less preparation and instructional time than extended instruction, offering teachers a practical way to teach more vocabulary to ELs.

This study evaluated the effects of a cross-age peer learning program targeting vocabulary and comprehension in kindergarten and fourth-grade classrooms with substantial proportions of English Learners (ELs). The study followed a quasi-experimental design with 12 classrooms (6 kindergarten and 6 fourth grade) in the intervention group and 12 classrooms (6 kindergarten and 6 fourth grade) in the comparison group. Students were assessed before and after the 14-week intervention via curriculum-aligned and norm-referenced vocabulary and comprehension assessments. Findings of analyses of researcher-developed measures showed positive and significant intervention effects on receptive and expressive vocabulary in kindergarten and fourth grade and comprehension (i.e., understanding of text and strategy use) in fourth grade. Findings of analyses of norm-referenced measures showed positive and significant intervention effects on receptive vocabulary in kindergarten. In general, the intervention had similar effects for ELs and non-ELs.

The Common Core State Standards and the Next Generation Science Standards require students to understand and produce academic language that appears in informational text. Vocabulary is a critical domain of academic language, but English language learners (ELLs) come to the English Language Arts classroom with more limited English vocabulary than their English-proficient peers. This study compared 2 methods of vocabulary instruction: extended vocabulary instruction and embedded vocabulary instruction. Teachers implemented both approaches in the context of interactive shared reading, in which teachers and students read and discussed informational text. A total of 30 teachers in 18 schools and 509 third- and fourth-grade Spanish-speaking ELLs in a large, high-poverty district in the southwestern United States participated. Findings indicate that although extended instruction was the more effective approach, embedded instruction also helped ELLs acquire general academic and domain-specific vocabulary--an important finding, given that embedded instruction requires considerably less instructional time.

This three-year longitudinal study investigated the role of language of instruction in moderating the relationships between initial levels of English oral language proficiency and Spanish reading comprehension and growth in English reading comprehension. The study followed Spanish-speaking English language learners in English-only literacy instruction, an early-exit bilingual program, or a late-exit bilingual program, from third through fifth grade. Students in all groups experienced significant growth in English reading comprehension. For the English-only group, initial levels of Spanish reading comprehension were not related to growth in English reading comprehension. However, for students in the two bilingually instructed groups, those who began with stronger Spanish reading comprehension skills grew faster in English reading comprehension than students without initial strong Spanish reading comprehension skills.
