This study examined empirical evidence about the relationship between motor skills at beginning of kindergarten and reading mathematics achievement end first grade, using Early Childhood Longitudinal Study—Kindergarten cohort national dataset (N = 12,583). Results hierarchical regression analyses demonstrated that early skills, especially visual add a small but unique amount variance to in grade even after controlling for initial demographic information. Furthermore,...
Between- and within-family changes in 4 dimensions of parent involvement children's learning were examined from prekindergarten to kindergarten first grade. Children's literacy, language, mathematics skills individually assessed at entry end Parents' provision cognitive stimulation decreased overall (d = −.26) grade −.53), variety out-of-home experiences increased .30). A substantial percentage the sample or their participation home-based school-based activities. The degree change predicted...
In response to growing research and policy interest in the developmental contexts of early literacy, this study examined relations between neighborhood socioeconomic well‐being, home literacy (parent–child shared reading number books at home), directly assessed outcomes among 551 Head Start students fall preschool. Structural Equation Models, well‐being predicted which turn (a latent variable derived from receptive vocabulary, letter‐word identification, concepts about print). Implications...
Research Findings: We examined relations among preschoolers' behavioral regulation, gender, and school readiness outcomes in preacademic classroom skills using a sample of South Korean preschoolers aged 3–5 (N = 229). Behavioral regulation was assessed direct measure, the Head–Toes–Knees–Shoulders task, which requires children to switch rules by responding opposite way 4 different oral commands. Results demonstrated nonsignificant gender differences academic but significant work-related...
Young children's engagement in shared reading refers to the extent of attention, behavioral involvement, and enjoyment during has been treated as an indicator reading-related motivation. In this study, we examined Shared Reading Engagement Rating Scale, a measure young classroom reading, tested its validity using data collected from Head Start children (n = 263). We conducted explorative factor analysis identified two factors, active interactive engagement. Confirmatory validated proposed...
Background Rapid growth in early childhood device usage has raised critical questions about the potential impact of digital storybooks on children's reading outcomes. The current study examined how two types multimedia animations – storyline elements or details illustrations influenced story comprehension and enjoyment young children. Methods Preschool children ( n = 86) read a storybook one three conditions: storyline‐element animations, illustration‐detail no additional animations. Two...
A dividing-type manifold system is one of the conventional flow distributors adopted to allocate main stream into multiple branches. In operating such a system, capability controlling discharge for each outlet (e.g., uniform distribution) required sustain performance and enhance efficiency various thermo-fluid processes in industry. this paper, we performed numerical experimental investigations on two-phase behaviors concentration dispersed phase) through pipe while varying pressure...
The current study attempted to investigate the nature and impact of home math talk low-income primary caregivers Head Start children during cooking (N = 46). Using hierarchical regression analysis, we examined predictability total specific types (i.e., number talk, operation measurement talk) for children's skills assessed in fall spring their preschool year. Caregivers' was not concurrently associated with skills, but math. For there were no main effects any type interaction identified....
Research Findings. The present study examined patterns of longitudinal associations between inhibitory control (IC) and early academic skills during the preschool kindergarten years. Using data from Head Start Family Child Experiences Survey Cohort 2009 (FACES 2009) (N = 939), a national set predominantly low-income children attending Start, two models were compared: (1) lagged path model predicting subsequent based on prior IC (2) cross-lagged reciprocal skills. Our results showed better...
This study investigates how interactive features embedded in the illustrations of storybook apps influenced young readers' story enjoyment and comprehension. Kindergartners second graders (N = 91) were randomly assigned to read an or noninteractive condition. Findings showed that children's self-reported did not differ when had versus illustrations. However, children condition scored higher on comprehension items than condition, particularly more story-related interactions available. Further...
Charge collection measurements performed on heavily irradiated p-spray DOFZ pixel sensors with a grazing angle hadron beam provide sensitive determination of the electric field within detectors. The data are compared complete charge transport simulation sensor which includes free carrier trapping and induction effects. A linearly varying based upon standard picture constant type-inverted effective doping density is inconsistent data. two-trap double junction model implemented in ISE TCAD...
The current study examined the complex associations among marital status, home environments, and family strain (i.e. income, maternal depressive symptoms, social support, parenting stress), as they predict preschool children's pre-academic skills at 36 54 months. Findings from NICHD Study of Early Child Care Youth Development (N = 897) showed that learning environment, which was significantly lower single-parent families, worked a mediator to explain relationship between families...
This study examined associations among low‐income mothers' use of attention‐getting utterances during shared book reading, preschoolers' verbal engagement and visual attention to their early literacy skills ( N = 51). Mother–child reading sessions were videotaped coded for each utterance, including talk, contextualized de‐contextualized print talk. Preschoolers' was assessed using two measures: by a rating scale involvement in discussion coding gaze. Findings indicated that talk positively...
Abstract The current study examined whether young children's executive functions and emotionality are related to childcare experiences they work as mediators explaining the associations between early school outcomes. Findings from a national sample of National Institute Child Health Human Development (NICHD) Study Early Care Youth ( N = 990) revealed that centre‐based care quality positively predicted preschool functions, which then were linked their academic skills social in kindergarten...
This paper reports on the sensor R&D activity for CMS pixel detector. Devices featuring several design and technology options have been irradiated up to a proton fluence of 1/spl times/10/sup 15/ n/sub eq//cm/sup 2/ at CERN PS. Afterward, they were bump bonded unirradiated readout chips tested using high energy pions in H2 beam line SPS. The chip allows nonzero suppressed full analogue therefore good characterization sensors terms noise charge collection properties. position dependence...
