Nurture thru Nature: Creating natural science identities in populations of disadvantaged children through community education partnership

In this article we describe the development, implementation, and some of the early impacts of Nurture thru Nature (NtN), an American after-school and summer program designed to introduce elementary school students in disadvantaged, urban public schools to natural science and environmental education. The program, which began operations in 2010 as a collaboration of Rutgers University, Johnson & Johnson, and New Brunswick, New Jersey, public schools, was motivated by broad concerns over the achievement gap in science and mathematics that has long characterized student performance in the state's suburban and inner-city schools. We present results from a classical experiment conducted in four elementary schools which suggest that NtN does improve grades and knowledge of science and nature.     

Assessing the play beliefs of African American mothers with preschool children

A rating scale measuring parent beliefs about play was developed and validated with a sample of 224 African American mothers of children attending Head Start. Principal components analyses of the Parent Play Beliefs Scale (PPBS) revealed two factors, Play Support and Academic Focus, which capture parent attitudes regarding the developmental significance of play. Maternal ratings of Play Support correlated positively with ratings of children's interactive peer play and were positively associated with parent education. Maternal ratings of Academic Focus were negatively correlated with prosocial peer play ratings and positively correlated with ratings of disruptive and disconnected play in children. Findings support the psychometric utility of the new measure. Future directions involving parent play beliefs in conceptual models of children's social competence during early childhood are discussed.

Mathematical language and mathematical abilities in preschool: A systematic literature review

It is well established that early general language during preschool is critical for children's mathematical abilities. In an attempt to further characterize this association between language and mathematics, an increasing number of studies show that one specific type of language, namely mathematical language or the key linguistic concepts that are required for performing mathematical activities, is even more critical to children's mathematical abilities. The purpose of this systematic review is to summarize the evidence on mathematical language and mathematical abilities. We focus on preschool children as nearly all of the existing work has been done at this age. We first explain how mathematical language has been defined across studies, and report how it has been evaluated in studies in preschool. Next, we present the results of our systematic review. Following the PRISMA guidelines and after a critical appraisal, we ended with a set of 18 papers that were all of sufficient methodological quality. In these studies, mathematical language was defined as terms that are about numbers and operations on numbers (e.g., nine), but also included linguistic terms that do not directly refer to numbers, yet are important to understand mathematical concepts (i.e., quantitative and spatial terms such as fewest and middle, respectively). Some of these studies evaluated children's performance on mathematical language tasks, while others evaluated the mathematical language input provided to the child by their (educational) environment (teachers/parents/interventionists). Mathematical language correlated positively with children's mathematical abilities, concurrently and longitudinally. It also directly affected children's mathematical abilities, as was shown by intervention studies. We discuss potential directions for future research and highlight implications for education, arguing for more support for teachers and parents to improve the use of mathematical language in the classroom and in home settings.     

Enhancing preschool children's vocabulary: Effects of teacher talk before,during and after shared reading

This observational study analyzed patterns of teacher extratextual talk as it occurs before, during, and after reading books to children, and the frequency and duration of teacher questioning by type (label, define, associate) on preschoolers’ receptive and expressive vocabulary knowledge. Over the course of 18 weeks, 13 teachers and 100 children participated in ninety 20-min small-group sessions of teacher-guided shared reading instruction. Teachers’ reading instruction was examined through videotaped observations using the Multi-Option Observation System for Experimental Studies (MOOSES™; Tapp, Wehby, & Ellis, 1995). Two findings, in particular, yielded relevant educational and theoretical implications. First, time spent after reading was significantly related to expressive vocabulary. However, question timing did not seem to matter in terms of receptive vocabulary outcomes. Second, duration of teacher association questioning was significantly related to receptive vocabulary outcomes while both frequency and duration of teacher vocabulary-related association-level questioning were related to expressive vocabulary. For receptive vocabulary, both vocabulary- and comprehension-related association-level questioning mattered. These findings complement the body of work demonstrating that engaging children in interactive shared reading that elicits their active participation is related to meaningful gains in children's language and literacy growth. Limitations of the study and directions for future research are discussed.     

The motor and cognitive development of overweight preschool children

The aim of this study was to investigate the development of overweight compared with healthy-weight children attending kindergartens in Munich, Germany. Mean age of the children at the beginning of the study was 53.2 months (SD?=?7.5); the duration of the study was 20 months. At the beginning of the study children were classified as overweight (n?=?32) or healthy weight (n?=?318) using BMI scores. Dependent variables were aspects of physical growth, physical fitness, body coordination, manual dexterity, and cognitive performance. A higher rate of socially disadvantaged children was overweight compared with socially advantaged children. There was no association between weight and sex. Motor skills improved over trials. Socially disadvantaged and overweight children performed less well in gross motor skills compared with children from backgrounds of higher socioeconomic (SE) status or healthy-weight children. There was also an association between weight and socioeconomic status: overweight children of lower SE status performed less well compared with overweight children of upper SE status in all gross motor tasks. No connection could be found between weight and manual dexterity and cognitive performance.     

The associations between teacher-child relationships and academic skills: A longitudinal study among Chinese preschool children

The current study followed a sample of 656 Chinese preschool children to examine reciprocal associations between teacher-child relationships and children’s academic skills by testing three cross-lagged models: the relationship-driven model, the child-driven model, and the reciprocal model. Fifty-nine head teachers reported teacher-child relationships, and children’s academic skills were assessed at three time points during the 2nd and 3rd preschool year. Results showed that the reciprocal model was the best fit in explaining the associations between teacher-child relationships and children’s academic skills (math achievement, character recognition and executive function), and the child-driven model was the best fit in explaining the relation between teacher-child relationships and children’s receptive vocabulary. The results contribute to understand the dynamic relations between teacher-child relationships and children's academic skills in the Chinese preschool context. Implications for educational practices are discussed.     

Psychometric evaluation of the Children's Behavior Questionnaire-Very Short Form in preschool children using parent and teacher report

Temperament is a developmentally important construct, hierarchically comprised of several lower-order dimensions subsumed under effortful control, negative affectivity, and surgency. The Children's Behavior Questionnaire-Very Short Form (CBQ-VSF) was developed as a brief measure of the higher-order factors of temperament to aid researchers in understanding the relation between these factors and other developmentally important constructs. In this study, we examined the psychometric properties of the CBQ-VSF in preschool children (N = 277) using teachers and parents as informants. Several dimensions of temperament emerged independently of the three higher-order factors. Comparing the extracted factors to other measures of temperament revealed limited convergent and discriminant validity. Further, similar teacher and parent report factors did not correlate. Based on these findings, it is suggested that the CBQ-VSF be refined to better reflect core dimensions that comprise the higher-order factors.     

Individual differences in dynamic measures of verbal learning abilities in young twin pairs and their older siblings

We explored the genetic background of individual differences in dynamic measures of verbal learning ability in children, using a Dutch version of the Auditory Verbal Learning Test (AVLT). Nine-year-old twin pairs (N = 112 pairs) were recruited from the Netherlands Twin Register. When possible, an older sibling between 10 and 14 years old participated as well (N = 99). To assess verbal learning, non-linear curves were fitted for each child individually. Two parameters were estimated: Learning Speed (LS) and Forgetting Speed (FS). Larger twin correlations in monozygotic (MZ) than in dizygotic (DZ) and sibling pairs for LS and FS indicated the importance of genetic factors in explaining variation in these traits. The heritability estimate (percentage of variance explained by genetic factors) for LS was 43% for both twins and siblings. For FS heritability was estimated at 20% in twins and was slightly higher (30%) in their older siblings.     

Type of day-care and preschool intellectual development in disadvantaged children

Levels and patterns of intellectual development of 3 groups of socioeconomically disadvantaged children were compared. The groups consisted of (1) children who were randomly assigned to receive extensive university-based intervention group day-care, (2) children whose parents placed them in community day-care centers for varying amounts of time, or (3) children whose parents chose little to no center-based day-care for their children. Two repeated-measures analyses of variance were performed to identify possible day-care effects on IQ level and on patterns of infant and preschool cognitive development. The results suggest that quality community day-care, as well as intervention day-care, may positively change both the level and pattern of preschool intellectual development of socioeconomically disadvantaged children.     

The contributions of parental management language to executive function in preschool children

This study investigated relations between preschoolers’ emergent executive function skills and their interactions with parents, with particular focus on the verbal utterances parents use to guide children's behavior (i.e., management language). Parent–child dyads (n = 127) were videotaped during a structured play task and the frequency of two types of management language, Direction (high control) and Suggestion (low control), was observed. Children's executive function was assessed using the Head–Toes–Knees–Shoulders (HTKS) task. Latent growth modeling was used to investigate relations between management language and the development of children's executive function. Direction language (i.e., commands) was negatively associated with children's age three executive function but not significantly related to the rate of executive function development over time. Conversely, Suggestion language (i.e., questions and statements that offer children some degree of choice) was positively related to executive function at age three but negatively related to growth. The potential importance of management language as a parenting behavior that contributes to various aspects of children's self-regulation during preschool and kindergarten is discussed.     

Comparing Imitation Responding and IBT for children with ASD,a preschool intervention

The present study examined the effectiveness of two interventions, Imitation Responding (IR) and Intensive Behavior Treatment (IBT) used as initial treatment programs for autistic children enrolled in ordinary preschools. The interventions were carried out by parents and/or preschool teachers with supervision from Child Adolescent Habilitation and Health Clinics. Children were randomly assigned to either the IR group or the IBT group. The IR group received a new focused imitation treatment averaging 2.2 hours per week, while the children in the IBT group received 14.4 hours treatment per week. The outcome was measured with subscales from PEP‐3 and Vineland‐II, covering language and social domains. The between‐group comparison revealed no significant differences in effect of treatment during the 5 months that encompassed the period from pre‐ to posttest. Within‐group comparisons revealed significant changes on four subscales for the IR‐group, with the highest effect sizes for play and expressive language, while for the children in the IBT‐group a significant gain was evident for five subscales with the highest effect sizes observed for expressive and receptive language. These findings suggest that IR can be used as an initial and complementary method in settings where IBT is usually the primary treatment of choice.     

High-throughput sequencing identifies salivary microbiota in Chinese caries-free preschool children with primary dentition

Objectives: The study aimed at identifying salivary microbiota in caries-free Chinese preschool children using highthroughput sequencing. Methods: Saliva samples were obtained from 35 caries-free preschool children(18 boys and 17 girls)with primary dentition, and 16 S ribosomal DNA(r DNA) V3–V4 hypervariable regions of the microorganisms were analyzed using Illumina MiSeq. Results: At 97% similarity level, all of these reads were clustered into 334 operational taxonomic units(OTUs). Among these, five phyla(Firmicutes, Proteobacteria, Actinobacteria, Bacteroidetes, and Candidate division TM7) and13 genera(Streptococcus, Rothia, Granulicatella, Prevotella, Enterobacter, Veillonella, Neisseria, Staphylococcus, Janthinobacterium, Pseudomonas, Brevundimonas, Devosia, and Gemella) were the most dominant, constituting 99.4% and 89.9% of the salivary microbiota, respectively. The core salivary microbiome comprised nine genera(Actinomyces, Capnocytophaga, Gemella,Granulicatella, Lachnoanaerobaculum, Neisseria, Porphyromonas, Rothia, and Streptococcus). Analysis of microbial diversity and community structure revealed a similar pattern between male and female subjects. The difference in microbial community composition between them was mainly attributed to Neisseria(P=0.023). Furthermore, functional prediction revealed that the most abundant genes were related to amino acid transport and metabolism. Conclusions: Our results revealed the diversity and composition of salivary microbiota in caries-free preschool children, with little difference between male and female subjects.Identity of the core microbiome, coupled with prediction of gene function, deepens our understanding of oral microbiota in cariesfree populations and provides basic information for associating salivary microecology and oral health.     

Executive function and verbal self-regulation in childhood: Developmental linkages between partially internalized private speech and cognitive flexibility

Recent studies have noted that executive function and the use of self-regulatory private speech are related in childhood, and proposed that the critical leap that occurs in the development of executive function between the ages of three and six years may be due to the onset of language-based self-regulatory functions at this age. This research explored the relationship between executive function and private speech in a cross-sectional study of 81 children between four and seven years of age. The children performed an executive function task, the Dimensional Change Card Sort (DCCS), and children's use of private speech was observed during a categorization task. The results indicated that, after controlling for children's age, gender, verbal abilities, and fluid reasoning, children's use of partially internalized private speech during the categorization task was significantly related to the number of phases successfully passed on the DCCS task, which required them to switch between card sorting rules. Children who used more partially internalized private speech were more likely to pass the most challenging phase of the DCCS task that assesses the ability to flexibly use different sorting rules according to a higher-order rule. We discuss the role of verbal mediation in the development of cognitive flexibility and its implications for the design of intervention programs for children who possess deficits of executive function.     

A pilot study of early childhood mental health consultation for children with behavioral problems in preschool

This study reports the findings of a pilot demonstration project called Together for Kids, which used a mental health consultation model to address the needs of young children with challenging behaviors who are identified in preschool classrooms. The study was conducted in four preschool programs and one Head Start program serving children ages 3–5, including both private-pay families and those using public subsidies. Rates of significant behavior problems as assessed by preschool teachers using a standardized scale were high, with 34% of all children enrolled in preschool classrooms in these sites over a 3-year period identified at-risk of externalizing or internalizing problems. Classroom teachers, as well as individual children and families identified as at-risk, were provided services, including, classroom observation and teacher training, individual child assessment and therapy, family assessment and support, and referrals for other family needs. Analysis of outcomes for 47 children and families with externalizing behavior problems who received individualized consultation, compared to 89 control children, and analysis of outcomes of a matched group of 19 intervention and 19 control children, revealed that the intervention was associated with significant improvements in classroom aggressive and maladaptive behavior, and growth in adaptive behavior. Improvements in child behavior were associated with total hours of individual child services provided, and with improvements in child developmental skills. Significant reductions in the rate of children suspended or terminated from child care programs were also found. Implications for further development of models of early childhood mental health consultation are discussed.

Prevalence,gender ratio and gender differences in reading‐related cognitive abilities among Chinese children with dyslexia in Hong Kong

Based on the data of the normative study of the Hong Kong test of specific learning difficulties in reading and writing, and the Test of visual‐perceptual skills (non‐motor)—Revised, 99 children aged between 6 and 10½ years were identified as children with dyslexia out of the normative sample of 690 children. By excluding 12 children known to score below average in IQ, 87 children, including 20 children not tested for IQ, could be regarded as children with dyslexia, yielding a prevalence rate of 12.6% and a boy:girl gender ratio of 1.6 to 1. The figures would become 9.7% and 2.0 to 1 if the 20 children were omitted from computation. However, gender imbalance could not be readily explained by gender differences in reading‐related cognitive abilities, as there were only minor and subtle differences. Regression analyses to evaluate the relative contribution of different cognitive abilities to reading and writing suggested that orthographic knowledge and naming speed were most important among children with dyslexia. Implications of the findings and the need for early intervention are discussed.     

An evaluation of the preschool PATHS curriculum on the development of preschool children

This study evaluated the efficacy of preschool Promoting Alternative Thinking Strategies (PATHS), an early years curriculum designed to improve children’s social and emotional competence, and reduce problem behaviour. Fifty-seven children aged three to four years took part in the study over one academic year. The control group (Group 1) received no preschool PATHS curriculum, Group 2 received an adapted version, and Group 3 received the full preschool PATHS curriculum. Relevant vocabulary and perspective-taking skills were assessed before and after the intervention alongside behavioural questionnaires completed by preschool staff and parents. Staff views were investigated. Group 3 significantly improved on some measures, but Groups 1 and 2 showed no significant improvements. Children who received the full version of the preschool PATHS curriculum exhibited less problem behaviour, showed better emotional knowledge, better attentional skills, and better prosocial behaviour. The contribution of the local Educational Psychology Service to the initiative is discussed.
