Sociodemographic and nutritional correlates of neurobehavioral development: a study of young children in a rural region of Ecuador

To identify and describe the sociodemographic and nutritional characteristics associated with neurobehavioral development among young children living in three communities in the northeastern Andean region of Cayambe-Tabacundo, Ecuador. Women in the study communities who had a child 3 to 61 months of age completed a questionnaire about maternal and child health and sociodemographic characteristics. The Ages and Stages Questionnaire (ASQ) was directly administered to 283 children by two trained interviewers. Growth measurements and a hemoglobin finger-prick blood test were obtained in 2003–2004. Prevalence of developmental delay was calculated, and associations between child development and maternal, child, and household characteristics were explored. High frequencies of developmental delay were observed. Children 3 to 23 months old displayed delay in gross motor skills (30.1%), and children 48 to 61 months old displayed delay in problem-solving skills (73.4%) and fine motor skills (28.1%). A high frequency of both anemia (60.4%) and stunting (53.4%) was observed for all age groups. Maternal educational level was positively associated with communication and problem-solving skills, and monthly household income was positively associated with communication, gross motor, and problem-solving skills. The results suggest a high prevalence of developmental delay and poor child health in this population. Child health status and the child’s environment may contribute to developmental delay in this region of Ecuador, but sociodemographic factors affecting opportunities for stimulation may also play a role. Research is needed to identify what is causing high percentages of neurobehavioral developmental delay in this region of Ecuador.

A Story of English Language Learning – How Can Children’s Literature be Used in Teaching Vocabulary to Young English Language Learners? : - A Literature Review

This study aims to find research relating to the use of children’s literature to promote vocabulary development in young children, particularly English language learners in Sweden. The main questions address how (methods) children’s literature can be used and why (reasons) children’s literature is often recommended for the teaching of vocabulary to young learners. The study also aims to explore reasons against the use of children’s literature in vocabulary teaching found in previous research. A systematic literature review was carried out, including results from five empirical studies. The studies involved native speakers, second language learners and foreign language learners from various backgrounds. The results suggest that while research has shown children’s literature to be a good tool to use with young learners, careful lesson planning needs to be carried out. Direct instruction and scaffolding using pictures, technology and gestures is recommended. Hence, the teacher plays an important part for the vocabulary development using children’s literature in the classroom.

The oral language skills of young offenders: a pilot invesitgation

Although there is a large body of evidence attesting to the poor social skills of juvenile offenders, few workers have examined the underlying language skills of this population. This pilot study investigated the language skills of a group of young offenders in comparison to non-offending school students. Data were gathered from 15 community-based young offender males, aged between 13 and 21 years (M = 16.5 years, SD = 2.1) from the Victorian southern region Juvenile Justice Units. The comparison group comprised 15 male students, aged between 15 and 17 years (M = I 6.4 years; SD = 0.5 I) from government high schools in south-eastern metropolitan Melbourne. Each participant completed a narrative discourse task and measures of speed of processing, and abstract language. It was hypothesised that the young offender group would perform more poorly on each of the language tasks than the comparison group. Independent t tests (with a modified alpha level to control for family-wise error rates) showed that there were significant differences in the expected direction, on all language measures. Notwithstanding the pilot nature of the investigation, implications of these findings for both further research and intervention/early intervention are described.

Calculators, mathematics and young children : a study of six children using calculators as part of the mathematics curriculum during their first two years of school

The thesis investigates the role a calculator can play in the developing number knowledge of three girls and three boys as part of their mathematics program, during their first two years at primary school. Random sampling was used initially to select six girls and six boys from the twenty-four children entering a 1993 prep class. These twelve children were interviewed on entrance to school and based on the performance of the twelve children on the initial interview, a girl and a boy were chosen from the higher, middle and lower achievers to take part in the full study. The class teachers involved were previously participants in the ‘Calculators in Primary Mathematics’ research program and were committed to the use of calculators in their mathematics program. A case study approach using qualitative methods within the activity theory framework is used to collect relevant data and information, an analysis of five interviews with each child and observations of the children in forty-one classroom lessons provides comprehensive data on the children's developing number knowledge during the two years. The analysis questionnaires establishes each teacher's perceptions of the children's number learning at the beginning and end of each year, compares teacher expectations with children's actual performance for the year and compares curriculum expectations with children's actual performance. A teacher interview established reasons for changes in teaching style; teacher expectations; children's number learning; and was used to confirm my research findings. An activity theory framework provides an appropriate means of co-coordinating perspectives within this research to enable a description of the child's number learning within a social environment. This framework allows for highlighting the mediation offered by the calculator supporting the children's number learning in the classroom. Levels of children's developing number knowledge reached when working with a calculator and as a result of calculator use are mapped against the levels recommended in ‘Mathematics in the National Curriculum’ (National Curriculum Council, December 1988), and the Curriculum and Standards Framework: Mathematics (Board of Studies 2000). Findings from this comparison illustrate that the six children's performance in number was enhanced when using a calculator and indicate that on-going development and understanding of number concepts occurred at levels of performance at least two years in advance of curriculum recommendations for the first two years of school.

Maternal feeding practices predict weight gain and obesogenic eating behaviours in young children : a prospective study

Background Maternal feeding practices have been proposed to play an important role in early child weight gain and obesogenic eating behariours. However, to date longitudinal investigations in young children exploring these relationships have been lacking. The aim of the present study was to explore prospective relationships between maternal feeding practices, child weight gain and obesogenic eating behaviours in 2-year-old children. The competing hypothesis that child eating behaviours predict changes in maternal feeding practices was also examined.

Methods A sample of 323 mother (mean age = 35 years, + 0.37) and child dyads (mean age = 2.03 years, + 0.37 at recruitment) were participants. Mothers completed a questionnaire assessing parental feeding practices and child eating behaviours at baseline and again one year later. Child BMI (predominantly objectively measured) was obtained at both time points.

Results Increases in child BMI z-scores over the follow-up period were predicted by maternal instrumental feeding practices. Furthermore, restriction, emotional feeding, encouragement to eat, weight-based restriction and fat restriction were associated prospectively with the development of obesogenic eating behaviours in children including emotional eating, tendency to overeat and food approach behaviours (such as enjoyment of food and good appetite). Maternal monitoring, however, predicted decreases in food approach eating behaviours. Partial support was also observed for child eating behaviours predicting maternal feeding practices.

Conclusions Maternal feeding practices play an important role in the development of weight gain and obesogenic eating behaviours in young children and are potential targets for effective prevention interventions aiming to decrease child obesity.

How do early childhood teachers understand and support the needs of young English language Learners

In Australia, over one third of all children in Early Childhood programs speak a first language other than English. Despite considerable work into teachers' beliefs on cultural diversity, attention to aspects of second language acquisition in the Early Years has been limited within the Early Childhood field. This paper reports on a small study investigating how four early childhood educators understand theory of Second Language Acquisition (SLA) and bilingualism, and how they cater for language-minority students in their programs. The findings revealed a complex interplay between the way participants interpret and support the needs of these children, their experience in the field, and professional education. The teachers in the study reveal various perspectives on how SLA and bilingualism manifest during the early years, and how they affect the learning of children with a Language Background other than English (LBOTE). The teachers also seemed to rely on experiential and intuitive approaches in planning and teaching English Language Learners (ELLs). This study brings new perspectives to understanding the nature of teachers' beliefs and practice regarding English language learners.

Does playing a sports active video game improve young children's ball skill competence?

OBJECTIVES: Actual and perceived object control (commonly ball) skill proficiency is associated with higher physical activity in children and adolescents. Active video games (AVGs) encourage whole body movement to control/play the electronic gaming system and therefore provide an opportunity for screen time to become more active. The purpose of this study was to determine whether playing sports AVGs has a positive influence on young children's actual and perceived object control skills. DESIGN: Two group pre/post experimental design study. METHODS: Thirty-six children aged 6-10 years old from one school were randomly allocated to a control or intervention condition. The Test of Gross Motor Development-3 assessed object control skill. The Pictorial Scale of Perceived Competence for Young Children assessed perceived object control skill. The intervention consisted of 6×50min lunchtime AVG sessions on the Xbox Kinect. Two to three sport games were chosen for participants to play each session. General linear models with either perceived object control or actual object control skill as the outcome variables were conducted. Each base model adjusted for intervention status and pre-score of the respective outcome variable. Additional models adjusted for potential confounding variables (sex of child and game at home). RESULTS: No significant differences between the control and intervention groups were observed for both outcomes. CONCLUSIONS: This study found that playing the Xbox Kinect does not significantly influence children's perceived or actual object control skills, suggesting that the utility of the Xbox Kinect for developing perceived and actual object control skill competence is questionable.

How important is young children's actual and perceived movement skill competence to their physical activity?

OBJECTIVES: To determine the associations between young children's actual and perceived object control and locomotor skills and physical activity and whether associations differ by sex. DESIGN: Cross sectional study. METHODS: A total of 136 children consented. Children had actual skill (Test of Gross Motor Development-2), perceived skill (Pictorial Scale of Perceived Movement Skill Competence for Young Children), and moderate- to vigorous-intensity physical activity (MVPA) (accelerometers) assessed. Independent t-tests assessed sex differences. A regression (with MVPA as the outcome) was performed with all predictor variables (i.e. Actual Object Control, Actual Locomotor, Perceived Object Control, and Perceived Locomotor). Model 2 also adjusted for age, sex, accelerometer wear time and whether the child was from an English speaking background. Interaction terms between the respective actual or perceived skill factor and sex were added to assess sex differences. RESULTS: Analyses were conducted on 109 children (59 boys, 50 girls; mean age=6.5 years, SD=1.0). Boys had higher actual and perceived object control skill and were more active by an average of 19min per day. There were no sex differences in locomotor skills. There were no associations between skill factors and MVPA, except for girls, where locomotor skill was a significant predictor of MVPA (B=3.66, p=0.016). CONCLUSIONS: Actual rather than perceived skill competence was more important to MVPA in this sample. Locomotor skill competence may be more important than object control skill competence for girls as they may engage in types of physical activity that do not require object control mastery.

A meta-analysis of cross sectional studies investigating language in maltreated children

Purpose: In this review article, meta-analysis was used to summarize research investigating language skills in maltreated children. Method: A systematic search of published studies was undertaken. Studies were included in the meta-analysis if they investigated language skills in groups comprising maltreated and nonmaltreated children. Studies were selected if these 2 groups of children were of comparable age and from a similar socioeconomic background. Results: A total of 26 studies were identified that met the inclusion criteria. Results from the meta-analysis showed that maltreated children demonstrated consistently poorer language skills with respect to receptive vocabulary (k = 19; standardized mean difference [SMD] = .463; 95% confidence interval [CI; .293, .634]; p < .001), expressive language (k = 4; SMD =.860; 95% CI [.557, 1.163]; p < .001), and receptive language (k = 9; SMD =.528; 95% CI [.220, .837]; p < .001). Conclusion: Together, these results indicate a reliable association between child maltreatment and poor language skills.

Effects of Systematic Social Skill Training on the Social-Communication Behaviors of Young Children with Autism During Play Activities

A systematic social skills training intervention to teach reciprocal sharing was designed and implemented with triads of preschool-age children, including one child with an autism spectrum disorder (ASD) and two untrained classroom peers who had no delays or disabilities. A multiple-baseline research design was used to evaluate effects of the social skills training intervention on social-communication and sharing behaviors exhibited by the participants with ASD during interactive play activities with peers. Social-communication behaviors measured included contact and distal gestures, touching peers and speaking. Four sharing behaviors were also measured, including sharing toys and objects, receiving toys and objects, asking others to share, and giving requested items. Results indicated considerable gains in overall social-communication behaviors. The greatest improvements were observed in the participants’ use of contact gestures and speaking. Slightly increasing trends were noted and suggested that participants with ASD made modest gains in learning the sharing skills taught during social skills training lessons. Social validity data indicate that participants with ASD and peer participants found the intervention appropriate and acceptable, and staff perception ratings indicated significant changes in the social skills of participants with ASD. Study outcomes have practical implications for educational practitioners related to enhancing social-communication and social interactions of young children with ASD. Study limitations and future directions for research are discussed.
