Early childhood language gains, kindergarten readiness, and Grade 3 reading achievement.

In this preregistered study, we used latent change score models to address two research aims: (1) whether preschool-aged children's language gains, over a year of early childhood education, were associated with later performance on state-mandated, literacy-focused kindergarten readiness and Grade 3 reading achievement assessments, and (2) whether gains in language, a more complex skill, predicted these outcomes after controlling for more basic emergent literacy skills. There were 724 participating children (mean = 57 months; 51% male; 76% White, 12% Black, 6% multiple races, and 5% Hispanic or Latino). We found that language gains significantly predicted kindergarten readiness when estimated in isolation (effect = 0.24 SDs, p < .001), but not when gains in letter knowledge and phonological awareness were also included.

Small-Group, Emergent Literacy Intervention Under Two Implementation Models: Intent-to-Treat and Dosage Effects for Preschoolers at Risk for Reading Difficulties.

Preschool-age children identified as at risk for later reading difficulties can benefit from supplemental, small-group emergent literacy intervention. As such interventions become commercially available and marketed to preschool programs, it is important to understand their impacts when implemented by intended end users under routine conditions. In this study, we examined the effects of the Nemours BrightStart! (NBS!) intervention on children's emergent literacy skills when implemented by teachers and community aides in authentic preschool classrooms. We randomly assigned 98 classrooms to one of three conditions (NBS! teacher-implemented, NBS! community aide-implemented, or control). Children enrolled in these classrooms who met eligibility criteria and were identified as at risk via an early literacy screener (n = 281) completed pretest and posttest emergent literacy assessments; those assigned to NBS! conditions received intervention from their classroom teacher or a community aide affiliated with a local kindergarten-readiness initiative. Intent-to-treat analyses showed no significant impacts of NBS! on any outcome, and an instrumental variable, as-treated approach showed one significant intervention effect on letter writing. Consequently, we did not replicate results of prior highly controlled efficacy trials. Findings have implications for revising the NBS! theory of change, conducting dosage and as-treated analyses, and moving research-based interventions toward scale-up.

The Contribution of Vocabulary, Grammar, and Phonological Awareness Across a Continuum of Narrative Ability Levels in Young Children.

Purpose Narrative skill represents a higher-level linguistic skill that shows incremental development in the preschool years. During these years, there are considerable individual differences in this skill, with some children being highly skilled narrators (i.e., precocious) relative to peers of their age. In this study, we explored the contribution of three lower-level language skills to a range of narrative abilities, from children performing below expected levels for their age to those performing much higher than the expected levels for their age. We speculated that individual differences in lower-level skills would contribute meaningfully to variability in narrative skills. Method Using a sample of 336 children between 3 and 6 years of age (M = 4.27 years, SD = 0.65), both multiple regression and quantile regression approaches were used to explore how vocabulary, grammar, and phonological awareness account for variance in children's "narrative ability index" (NAI), an index of how children scored on the Narrative Assessment Protocol-Second Edition relative to the expected performance for their age. Results Multiple regression results indicated that lower-level language skills explained a significant amount of variance (approximately 13%) in children's NAI scores. Quantile regression results indicated that phonological awareness and vocabulary accounted for significant variance in children's NAI scores at lower quantiles. At the median quantile, vocabulary and grammar accounted for significant variance in children's NAI scores. For precocious narrators, only vocabulary accounted for a significant amount of variance in children's NAI scores. Conclusion Results indicate that lower-level language skills work in conjunction to support narrative skills at different ability levels, improving understanding of how lower-level language skills contribute across a spectrum of higher-level linguistic abilities.

Development of the Narrative Assessment Protocol-2: A Tool for Examining Young Children's Narrative Skill.

Purpose Narrative skill, a child's ability to create a temporally sequenced account of an experience or event, is considered an important domain of children's language development. Narrative skill is strongly predictive of later language and literacy and is emphasized in curricula and educational standards. However, the need to transcribe a child's narrative and the lack of psychometrically justified scoring methods have precluded broad consideration of narrative skill among practitioners. We describe the development and validation of the Narrative Assessment Protocol-2 (NAP-2), an assessment of narrative skill for children ages 3-6 years, which uses event-based frequency scoring directly from a video recording of a child's narrative. Method The NAP-2 underwent a rigorous development process involving creation of four wordless picture books and associated scripts and identification of a broad item pool, including aspects of narrative microstructure and macrostructure. We collected two narratives from each of 470 children using the NAP-2 elicitation materials and scored each with the 60 items in the initial item pool. Results Cross-validated exploratory factor analyses indicated a single narrative skill factor. Rasch measurement analysis led to selection of 20 items that maintained high reliability while having good fit to the model and no evidence of differential item functioning across books and gender. Conclusions The NAP-2 offers a psychometrically sound and easy-to-use assessment of narrative skill for children ages 3-6 years. The NAP-2 is available freely online for use by speech-language pathologists, educational practitioners, and researchers. Supplemental Material https://doi.org/10.23641/asha.11800779.

Early childhood educators' knowledge about language and literacy: Associations with practice and children's learning.

Educators' language and literacy knowledge is considered important for informing classroom practices and thereby supporting children's early language and literacy development. This includes both disciplinary content knowledge (knowledge concerning how oral and written language are structured and map to one another) and knowledge for practice (knowledge of effective strategies and practices for supporting early language and literacy). In this study, we examined the associations among 485 early childhood educators' content knowledge and knowledge for practice, their observed language and literacy practices, and the emergent literacy learning of 2004 children enrolled in their classrooms. We found significant, positive correlations between measures of educators' content knowledge and knowledge for practice and classroom practice, indicating that early childhood educators with greater levels of knowledge tended to exhibit more desirable classroom language and literacy practices. We also found significant, positive associations between educators' knowledge and children's print concept, letter naming, and phonological awareness learning, but not children's oral language learning. The associations between educators' knowledge and children's print concept learning were mediated by classroom practice. Together, these results reiterate the importance of educators' language and literacy knowledge and also provide some support for practice as the mechanism through which knowledge relates to children's learning.

The Effectiveness of a Large-Scale Language and Preliteracy Intervention: The SPELL Randomized Controlled Trial in Denmark.

The present article reports results of a real-world effectiveness trial conducted in Denmark with six thousand four hundred eighty-three 3- to 6-year-olds designed to improve children's language and preliteracy skills. Children in 144 child cares were assigned to a control condition or one of three planned variations of a 20-week storybook-based intervention: a base intervention and two enhanced versions featuring extended professional development for educators or a home-based program for parents. Pre- to posttest comparisons revealed a significant impact of all three interventions for preliteracy skills (= .21-.27) but not language skills (d = .04-.16), with little differentiation among the three variations. Fidelity, indexed by number of lessons delivered, was a significant predictor of most outcomes. Implications for real-world research and practice are considered.

Age-Related Progressions in Story Structure in Young Children's Narratives.

Purpose: Prior theoretical and empirical work has referenced several broad stages of narrative development, particularly in terms of young children's understanding of story structure. However, there is considerable variation in how story structure has been defined and assessed across these studies. The aims of the present study were threefold: (a) to test the unidimensionality of items designed to assess story-structure knowledge, (b) to examine story-structure item difficulty levels, and (c) to examine age-related progressions on individual story-structure components across 3-, 4-, 5-, and 6-year-olds. Method: Participants included 386 children (M = 4.8 years, SD = 11.67 months) from the Narrative Assessment Protocol study (http://www.narrativeassessment.com/), which was designed to revise a new narrative assessment tool for children between the ages of 3 and 6 years. Results: Factor analysis indicated that 16 of 21 items reflecting story-structure knowledge constituted a unidimensional construct. Individual story-structure item analyses further revealed that establishing subgoals and tracking the overall goals in the stories were particularly challenging for 3- and 4-year-olds. Conclusion: These findings hold implications for refinement of theoretical models of story-structure emergence in early childhood.

Do Children's Learning-Related Behaviors Moderate the Impacts of an Empirically-Validated Early Literacy Intervention?

The present study included 314 children who had been involved in Project STAR, and explored how two learning-related behaviors, interest in literacy and effortful control, moderated the impact of the literacy intervention on reading outcomes. Results indicated significant associations of both learning-related behaviors with reading, with the children with the highest literacy interest and effortful control in the intervention group showing the highest reading outcomes. These results indicate that accounting for a greater breadth of possible moderators of intervention impacts is an important area to explore.

Professional Development for Early Childhood Educators: Efforts to Improve Math and Science Learning Opportunities in Early Childhood Classrooms.

Because recent initiatives highlight the need to better support preschool-aged children's math and science learning, the present study investigated the impact of professional development in these domains for early childhood educators. Sixty-five educators were randomly assigned to experience 10.5 days (64 hours) of training on math and science or on an alternative topic. Educators' provision of math and science learning opportunities were documented, as were the fall-to-spring math and science learning gains of children (n = 385) enrolled in their classrooms. Professional development significantly impacted provision of science, but not math, learning opportunities. Professional development did not directly impact children's math or science learning, although science learning was indirectly affected via the increase in science learning opportunities. Both math and science learning opportunities were positively associated with children's learning. Results suggest that substantive efforts are necessary to ensure that children have opportunities to learn math and science from a young age.

Exploring Preschool Children's Science Content Knowledge.

RESEARCH FINDINGS: The purpose of this study was to describe children's science content knowledge and examine the early predictors of science content knowledge in a sample of 194 typically developing preschool children. Children's science content knowledge was assessed in the fall (Time 1) and spring (Time 2) of the preschool year. Results showed that children exhibited significant gains in science content knowledge over the course of the preschool year. Hierarchical linear modeling results indicated that the level of maternal education (i.e., holding at least a bachelor's degree) significantly predicted children's Time 1 science content knowledge. Children's cognitive, math, and language skills at Time 1 were all significant concurrent predictors of Time 1 science content knowledge. However, only Time 1 math skills significantly predicted residualized gains in science content knowledge (i.e., Time 2 scores with Time 1 scores as covariates). PRACTICE OR POLICY: Factors related to individual differences in young children's science content knowledge may be important for early childhood educators to consider in their efforts to provide more support to children who may need help with science learning.

Mathematics and Science Learning Opportunities in Preschool Classrooms.

RESEARCH FINDINGS: The present study observed and coded instruction in 65 preschool classrooms to examine (a) overall amounts and (b) types of mathematics and science learning opportunities experienced by preschool children as well as (c) the extent to which these opportunities were associated with classroom and program characteristics. Results indicated that children were afforded an average of 24 and 26 minutes of mathematics and science learning opportunities, respectively, corresponding to spending approximately 25% of total instructional time in each domain. Considerable variability existed, however, in the amounts and types of mathematics and science opportunities provided to children in their classrooms; to some extent, this variability was associated with teachers' years of experience, teachers' levels of education, and the socioeconomic status of children served in the program. PRACTICE/POLICY: Although results suggest greater integration of mathematics and science in preschool classrooms than previously established, there was considerable diversity in the amounts and types of learning opportunities provided in preschool classrooms. Affording mathematics and science experiences to all preschool children, as outlined in professional and state standards, may require additional professional development aimed at increasing preschool teachers' understanding and implementation of learning opportunities in these two domains in their classrooms.

IRTs of the ABCs: children's letter name acquisition.

We examined the developmental sequence of letter name knowledge acquisition by children from 2 to five years of age. Data from 2 samples representing diverse regions, ethnicity, and socioeconomic backgrounds (ns = 1074 and 500) were analyzed using item response theory (IRT) and differential item functioning techniques. Results from factor analyses indicated that letter name knowledge represented a unidimensional skill; IRT results yielded significant differences between letters in both difficulty and discrimination. Results also indicated an approximate developmental sequence in letter name learning for the simplest and most challenging to learn letters--but with no clear sequence between these extremes. Findings also suggested that children were most likely to first learn their first initial. We discuss implications for assessment and instruction.

Increasing young children's contact with print during shared reading: longitudinal effects on literacy achievement.

Longitudinal results for a randomized-controlled trial (RCT) assessing the impact of increasing preschoolers' attention to print during reading are reported. Four-year-old children (N = 550) in 85 classrooms experienced a 30-week shared reading program implemented by their teachers. Children in experimental classrooms experienced shared-book readings 2 or 4 times per week during which their teachers verbally and nonverbally referenced print. Children in comparison classrooms experienced their teachers' typical book reading style. Longitudinal results (n = 356, 366) showed that use of print references had significant impacts on children's early literacy skills (reading, spelling, comprehension) for 2 years following the RCT's conclusion. Results indicate a causal relation between early print knowledge and later literacy skills and have important implications concerning the primary prevention of reading difficulties.

How Many Letters Should Preschoolers in Public Programs Know? The Diagnostic Efficiency of Various Preschool Letter-Naming Benchmarks for Predicting First-Grade Literacy Achievement.

Review of current federal and state standards indicates little consensus or empirical justification regarding appropriate goals, often referred to as benchmarks, for preschool letter-name learning. The present study investigated the diagnostic efficiency of various letter-naming benchmarks using a longitudinal database of 371 children who attended publicly funded preschools. Children's uppercase and lowercase letter-naming abilities were assessed at the end of preschool, and their literacy achievement on 3 standardized measures was assessed at the end of 1st grade. Diagnostic indices (sensitivity, specificity, and negative and positive predictive power) were generated to examine the extent to which attainment of various preschool letter-naming benchmarks was associated with later risk for literacy difficulties. Results indicated generally high negative predictive power for benchmarks requiring children to know 10 or more letter names by the end of preschool. Balancing across all diagnostic indices, optimal benchmarks of 18 uppercase and 15 lowercase letter names were identified. These findings are discussed in terms of educational implications, limitations, and future directions.

The impact of teacher responsivity education on preschoolers' language and literacy skills.

PURPOSE: This study examined the extent to which teacher responsivity education affected preschoolers' language and literacy development over an academic year. Additional aims were to determine whether children's initial language abilities and teachers' use of responsivity strategies were associated with language outcomes, in particular. METHOD: In this randomized controlled trial, preschool centers were assigned to a responsivity education intervention (n = 19 centers, 25 teachers, and 174 children) or a "business-as-usual" control condition (n = 19 centers, 24 teachers, and 156 children). Teachers within the intervention centers received training focused on a set of strategies designed to promote children's engagement and participation in extended conversational interactions across the school day. RESULTS: Hierarchical linear models showed no main effects on children's language skills, although moderating effects were observed such that the intervention appeared to have positive effects for children with relatively high initial language abilities. In addition, teacher use of responsivity strategies was positively associated with vocabulary development. With regard to children's literacy skills, there was a significant main effect of the intervention on print-concept knowledge. CONCLUSIONS: Although teacher responsivity education is viewed as benefitting children's language and literacy development, the impacts of this type of intervention on children's skills warrant further investigation.

Feasibility, efficacy, and social validity of home-based storybook reading intervention for children with language impairment.

PURPOSE: This study evaluated the feasibility, efficacy, and social validity of a parent-implemented intervention for promoting print knowledge in preschoolers with language impairment. METHOD: This trial involved 62 children and their parents. Each dyad completed a 12-week intervention program. Parents in the treatment group implemented print-focused reading sessions; parents in two comparison groups implemented sessions focused on either storybook pictures (picture-focused condition) or phonological concepts (sound-focused condition). RESULTS: Many parents completed the program successfully, but attrition was high; 23% of families dropped out of the program. Children who remained in the treatment group demonstrated significantly greater gains on 1 of 2 measures of print knowledge compared with those in the picture-focused condition but not the sound-focused condition. Parents generally reported favorable impressions of the program, although several aspects of the program received higher ratings from parents in the print-focused group. CONCLUSION: Study results raise questions about the feasibility of home-based intervention for some families; future research that examines the characteristics of families that may affect completion are needed. The causal effects of print-focused reading sessions are promising for addressing children's print-concept knowledge but not alphabet knowledge. Home-based reading intervention has considerable social validity as a therapeutic approach.

Developing Early Literacy Skills: A Meta-Analysis of Alphabet Learning and Instruction.

Alphabet knowledge is a hallmark of early literacy and facilitating its development has become a primary objective of pre-school instruction and intervention. However, little agreement exists about how to promote the development of alphabet knowledge effectively. A meta-analysis of the effects of instruction on alphabet outcomes demonstrated that instructional impacts differed by type of alphabet outcome examined and content of instruction provided. School-based instruction yielded larger effects than home-based instruction; small-group instruction yielded larger effects than individual tutoring programs. We found minimal evidence of transfer of alphabet instruction to early phonological, reading, or spelling skills. Implications for research and practice are discussed.

Fostering Alphabet Knowledge Development: A Comparison of Two Instructional Approaches.

Preschool-aged children (n = 58) were randomly assigned to receive small group instruction in letter names and/or sounds or numbers (treated control). Alphabet instruction followed one of two approaches currently utilized in early childhood classrooms: combined letter name and sound instruction or letter sound only instruction. Thirty-four 15 minute lessons were provided, with children pre- and post-tested on alphabet, phonological awareness, letter-word identification, emergent reading, and developmental spelling measures. Results suggest benefits of combined letter name and sound instruction in promoting children's letter sound acquisition. Benefits did not generalize to other emergent literacy skills.

Print-focused read-alouds in preschool classrooms: intervention effectiveness and moderators of child outcomes.

PURPOSE: This study was conducted to determine the effectiveness of teachers' use of a print-referencing style during whole-class read-alouds with respect to accelerating 4- and 5-year-old children's print-knowledge development. It also examined 8 specific child- and setting-level moderators to determine whether these influenced the relation between teachers' use of a print-referencing style and children's print-knowledge development. METHOD: In this randomized controlled trial, 59 teachers were randomly assigned to 2 conditions. Teachers in the experimental group (n = 31) integrated explicit references to specified print targets within each of 120 read-aloud sessions conducted in their classrooms over a 30-week period; comparison teachers (n = 28) read the same set of book titles along the same schedule but read using their business-as-usual reading style. Children's gains over the 30-week period on a composite measure of print knowledge were compared for a subset of children who were randomly selected from the experimental (n = 201) and comparison (n = 178) classrooms. RESULTS: When controlling for fall print knowledge, child age, and classroom quality, children who experienced a print-referencing style of reading had significantly higher print knowledge scores in the spring than did children in the comparison classroom. None of the child-level (age, initial literacy skills, language ability) or setting-level characteristics (program type, instructional quality, average level of classroom socioeconomic status, teachers' education level, teachers' experience) significantly moderated intervention effects. CLINICAL IMPLICATIONS: Considered in tandem with prior study findings concerning this approach to emergent literacy intervention, print-focused read-alouds appear to constitute an evidence-based practice with net positive impacts on children's literacy development.

Learning letter names and sounds: effects of instruction, letter type, and phonological processing skill.

Preschool-age children (N=58) were randomly assigned to receive instruction in letter names and sounds, letter sounds only, or numbers (control). Multilevel modeling was used to examine letter name and sound learning as a function of instructional condition and characteristics of both letters and children. Specifically, learning was examined in light of letter name structure, whether letter names included cues to their respective sounds, and children's phonological processing skills. Consistent with past research, children receiving letter name and sound instruction were most likely to learn the sounds of letters whose names included cues to their sounds regardless of phonological processing skills. Only children with higher phonological skills showed a similar effect in the control condition. Practical implications are discussed.
