This study examines the impacts of two AmeriCorps programs, Minnesota Reading Corps and Wisconsin Reading Corps, where AmeriCorps volunteers provide literacy tutoring to at-risk kindergarten through third-grade (K–3) students utilizing a response-to-intervention framework. This evaluation replicates a prior randomized controlled trial evaluation of the program 4 years later and for the first time evaluates the program model replicated in Milwaukee, Wisconsin. The results of the two evaluations showed that kindergarten and first-grade students who received a single semester of Reading Corps tutoring achieved significantly higher literacy assessment scores, and demonstrated meaningful and significant effects after a full-school year of the intervention for second- and third-grade students.

Significance Socioeconomic disparities in math proficiency are observable when children enter kindergarten, and these disparities persist through the school years. Research suggests that overall proficiency at kindergarten entry depends upon specific skills that all normally developing children age 3 to 5 y can learn. We therefore designed a procedure that enables teachers to assess the skills of each child and tailor instruction to child-specific levels of skill. The procedure is iterative: Assess, teach, reassess, and teach, with three assessments per school year. We found that children in classrooms randomly assigned to this procedure gained substantially more in their numerical proficiency than did children in control classrooms. The program did not delay growth in print literacy and increased verbal proficiency., Social inequality in mathematical skill is apparent at kindergarten entry and persists during elementary school. To level the playing field, we trained teachers to assess children’s numerical and spatial skills every 10 wk. Each assessment provided teachers with information about a child’s growth trajectory on each skill, information designed to help them evaluate their students' progress, reflect on past instruction, and strategize for the next phase of instruction. A key constraint is that teachers have limited time to assess individual students. To maximize the information provided by an assessment, we adapted the difficulty of each assessment based on each child’s age and accumulated evidence about the child’s skills. Children in classrooms of 24 trained teachers scored 0.29 SD higher on numerical skills at posttest than children in 25 randomly assigned control classrooms (P = 0.005). We observed no effect on spatial skills. The intervention also positively influenced children’s verbal comprehension skills (0.28 SD higher at posttest, P < 0.001), but did not affect their print-literacy skills. We consider the potential contribution of this approach, in combination with similar regimes of assessment and instruction in elementary schools, to the reduction of social inequality in numerical skill and discuss possible explanations for the absence of an effect on spatial skills.

This study evaluated the efficacy of the six-month 3Ts Home Visiting (3Ts-HV) curriculum, designed to empower socioeconomically disadvantaged caregivers with evidence-based knowledge and strategies in order to enrich the home language environment for their young children’s cognitive and language development. Using a matched pairs randomized controlled trial design, caregiver–child dyads were randomized into the 3Ts-HV intervention (n = 79) or Healthy Lifestyle control (n = 78) condition. Analyses of covariance revealed that compared with their control counterparts, the 3Ts-HV caregivers were more knowledgeable about early childhood cognitive and language development, and provided more language exposure for and engaged in more conversational turn-takings with their child. The 3Ts-HV caregivers also utilized more praise, explanations, and open-ended questions but less criticism, physical control, and intrusiveness than their control counterparts when interacting with their child. Findings provided empirical evidence supporting the immediate efficacy of the 3Ts-HV intervention in enhancing caregiver knowledge, the quantity of linguistic inputs, and the quality of caregiver interactions in the context of low-SES households, controlling for caregiver education level, language skills, and marital status.

This study reported the development and initial validation of the Survey of Parent/Provider Expectations and Knowledge (SPEAK), a self-administered questionnaire assessing expectations and knowledge about early childhood cognitive and language development. Development of the SPEAK was guided by the theory emphasizing the role of language input quality in young children’s language development. Items were refined through cognitive interviews ( N = 29), expert consultations, and the first field test ( N = 131). Rasch analysis following the second field test ( N = 346) resulted in a 17-item SPEAK (α = .84); expert review confirmed its content validity. A third field test with low-income caregivers ( N = 103) showed that higher SPEAK scores were correlated with higher education, receptive language ability, stronger endorsement of incremental mindset, and more language stimulation available to the child at home, supporting its concurrent validity. Findings provided preliminary evidence supporting the reliability and validity of the SPEAK to assess expectations and knowledge of early childhood cognitive and language development.

To investigate the impact of a spoken language intervention curriculum aiming to improve the language environments caregivers of low socioeconomic status (SES) provide for their D/HH children with CIHA to support children's spoken language development.Quasiexperimental.Tertiary.Thirty-two caregiver-child dyads of low-SES (as defined by caregiver education ≤ MA/MS and the income proxies = Medicaid or WIC/LINK) and children aged4.5 years, hearing loss of ≥ 30 dB, between 500 and 4000 Hz, using at least one amplification device with adequate amplification (hearing aid, cochlear implant, osseo-integrated device).Behavioral. Caregiver-directed educational intervention curriculum designed to improve D/HH children's early language environments.Changes in caregiver knowledge of child language development (questionnaire scores) and language behavior (word types, word tokens, utterances, mean length of utterance [MLU], LENA Adult Word Count (AWC), Conversational Turn Count (CTC)).Significant increases in caregiver questionnaire scores as well as utterances, word types, word tokens, and MLU in the treatment but not the control group. No significant changes in LENA outcomes.Results partially support the notion that caregiver-directed language enrichment interventions can change home language environments of D/HH children from low-SES backgrounds. Further longitudinal studies are necessary.

A child’s early language environment is critical to his or her life-course trajectory. Quantitative linguistic feedback utilizes the Language ENvironment Analysis (LENA) technology as a tool to analyze verbal interactions and reinforce behavior change. This exploratory pilot study evaluates the feasibility and efficacy of a novel behavior-change strategy, quantitative linguistic feedback, to influence adult linguistic behavior and, as a result, a child’s early language environment. Baseline LENA outcome measures (i.e., adult word count [AWC] and conversational turn count [CTC]) were obtained from a diverse sample of 17 nonparental caregivers and their typically developing children (charges) ages 10 to 40 months. Caregivers participated in a one-time educational intervention focusing on enriching a child’s home language environment, interpreting feedback from the baseline LENA recordings, and setting language goals for the following session. Post-intervention, six additional LENA recordings were obtained weekly to measure linguistic behavior. Caregivers showed a significant and prolonged increase from mean baseline to mean postintervention AWC and CTC as measured by LENA–AWC: mean difference = 395 words per hour, 31.6% increase, t = 3.29, p < .01; CTC: mean difference = 14 turns per hour, 24.9% increase, t = 3.54, p < .01. Preliminary results indicate that a one-time educational intervention combined with quantitative linguistic feedback may have a positive effect on caregiver language output, thus enhancing the child’s language environment. This study represents an initial step in the development and evaluation of a novel behavior-change strategy. We propose that quantitative linguistic feedback will add significantly to the arsenal of clinical and research tools used to evaluate and enrich a child’s early language environment.

We designed a parent-directed home-visiting intervention targeting socioeconomic status (SES) disparities in children's early language environments. A randomized controlled trial was used to evaluate whether the intervention improved parents' knowledge of child language development and increased the amount and diversity of parent talk. Twenty-three mother–child dyads (12 experimental, 11 control, aged 1;5–3;0) participated in eight weekly hour-long home-visits. In the experimental group, but not the control group, parent knowledge of language development increased significantly one week and four months after the intervention. In lab-based observations, parent word types and tokens and child word types increased significantly one week, but not four months, post-intervention. In home-based observations, adult word tokens, conversational turn counts, and child vocalization counts increased significantly during the intervention, but not post-intervention. The results demonstrate the malleability of child-directed language behaviors and knowledge of child language development among low-SES parents.
