Look Again: Pedagogical Demonstration Facilitates Children's Use of Counterevidence.

In learning about the world children must not only make inferences based on minimal evidence, but must deal with conflicting evidence and question those initial inferences when they appear to be wrong. Four experiments (N = 144) found that young children were significantly more likely to revise their initial inferences when conflicting evidence was explicitly demonstrated for them. Four- and five-year-old children saw deterministic evidence about which objects had causal powers, and then saw counterevidence conflicting with that initial pattern. Critically, the conflicting evidence was either demonstrated communicatively and pedagogically, or produced in an intentional but nonpedagogical manner. Only when evidence was explicitly demonstrated for them did children revise their initial hypothesis and use a subtle clue to infer the correct rule.

Teaching With Televised Stories: A Story-Focused Narrative Preview Supports Learning in Young Children.

Researchers examined the effects of previewing on preschoolers' comprehension of narrative and educational content in a television program. Children (3-5 years, N = 107) watched an educational math episode in one of three conditions: no-preview control, education-focused expository preview, or story-focused narrative preview. A main effect of previewing was found, controlling for age, character familiarity, prior knowledge, and visual attention. Specifically, the narrative preview enhanced both narrative comprehension (including central, incidental, and inferential content) and educational comprehension (including direct learning and transfer), compared to a no-preview control. Conversely, the expository preview had no effect on comprehension. Findings are interpreted with respect to story schema and relevant cognitive theories of learning from media. Implications for educational media production are discussed.

Questions Can Answer Questions About Mechanisms of Preschoolers' Selective Word Learning.

This study examined how inferences about epistemic competence and generalized labeling errors influence children's selective word learning. Three- to 4-year-olds (N = 128) learned words from informants who asked questions about objects, mentioning either correct or incorrect labels. Such questions do not convey stark differences in informants' epistemic competence. Inaccurate labels, however, generate error signals that can lead to weaker encoding of novel information. Preschoolers retained novel labels from both informants but were slower to respond in the Inaccurate Labeler condition. When the test procedure was not sensitive to the strength of information encoding, children performed above chance in both conditions and their response times did not differ. These results suggest that epistemic-level inferences and error generalizations influence preschoolers' selective word learning concurrently.

The Effects of Enrolling in Oversubscribed Prekindergarten Programs Through Third Grade.

This study leverages naturally occurring lotteries for oversubscribed Boston Public Schools prekindergarten program sites between 2007 and 2011, for 3,182 children (M = 4.5 years old) to estimate the impacts of winning a first choice lottery and enrolling in Boston prekindergarten versus losing a first choice lottery and not enrolling on children's enrollment and persistence in district schools, grade retention, special education placement, and third-grade test scores. There are large effects on enrollment and persistence, but no effects on other examined outcomes for this subsample. Importantly, children who competed for oversubscribed seats were not representative of all appliers and almost all control-group children attended center-based preschool. Findings contribute to the larger evidence base and raise important considerations for future prekindergarten lottery-based studies.

Toilet Training: Common Questions and Answers.

Toilet training is a significant developmental milestone in early childhood. Most U.S. children achieve the physiologic, cognitive, and emotional development necessary for toilet training by 18 to 30 months of age. Markers of readiness for toilet training include being able to walk, put on and remove clothing, and follow parental instruction; expressive language; awareness of a full bladder or rectum; and demonstrated dissatisfaction with a soiled diaper. Other readiness cues include imitating toileting behavior, expressing desire to toilet, and demonstrating bladder or bowel control (staying dry through a nap or through the night). Physicians should provide anticipatory guidance to parents beginning at about 18 to 24 months of age, noting the signs of toilet training readiness, and setting realistic expectations for parents. Parents should be counseled that no training method is superior to another. Parents should choose a method that is best suited to them and their child, and the method should use positive reinforcement. Complications of toilet training include stool toileting refusal, stool withholding, encopresis, hiding to defecate, and enuresis. These problems typically resolve with time, although some may require further investigation and treatment. Medical comorbidities such as Down syndrome, autism spectrum disorder, and cerebral palsy reduce the likelihood of successfully attaining full toilet training and often require early consultation with occupational therapists, developmental pediatricians, or other subspecialists to aid in toilet training.

School Performance in Third Grade After a Full-Day vs Part-Day Preschool Program.

This study assesses whether learning gains associated with full-day preschool were sustained through third grade by analyzing achievement scores and need for remediation.

III. TESTING FOR QUALITY THRESHOLDS AND FEATURES IN EARLY CARE AND EDUCATION.

In this chapter, we report on the analyses focusing on both quality thresholds and quality features. First, we address questions about quality thresholds, using two analytic approaches. The analyses ask whether there is evidence suggesting thresholds in the association between a specific quality measure and a specific child outcome. Second, we extend these analyses to ask whether each child outcome is more strongly related to global quality measures or to quality measures that measure teacher-child interactions or quality of instruction in a given content area. The research to date provides the basis for the articulation of two hypotheses related to quality thresholds and features: (1) the quality of ECE is a stronger predictor of residualized gains in child outcomes in classrooms with higher quality than in classrooms with lower quality and (2) more specific measures of quality are stronger predictors of residualized gains in child outcomes than are global measures. We turn now to analyses intended to address these hypotheses by using data from several data sets.

[The effectiveness of primary prevention interventions promoting physical activity and healthy eating in preschool children: A review of reviews]. / Wie wirksam sind ernährungs- und bewegungsbezogene primärpräventive Interventionen im Setting Kita? : Ein Review von Reviews.

BACKGROUND: During their preschool years children establish nutritional and physical activity (PA) habits that may contribute to the development of overweight and obesity. OBJECTIVE: To examine the evidence for effective interventions promoting healthy eating and PA in childcare settings. METHODS: We searched PubMed, the Cochrane Library, and Campbell Collaboration for systematic reviews published between 2007 and 2014. Ten systematic reviews and three meta-analyses met the inclusion criteria, including a total of 22 intervention studies. Intervention studies were conducted in North America (N = 14), Europe (N = 5), Asia (N = 2), and Australia (N = 1). Half of these addressed ethnic minority groups or socially disadvantaged children. We extracted information about the effects regarding anthropometric measures, eating habits, and physical activity, as well as the characteristics of effective interventions, and summarized them narratively. RESULTS: Evidence for intervention effects on anthropometric measurements was inconclusive. Seven out of nine studies showed beneficial effects on diet-related outcomes. Only isolated effects were reported on improvements in PA. Reviews indicated that interventions which comprised (1) the development of skills and competencies, (2) medium to high parental involvement, and (3) information on behavior-health links for parents were more effective. CONCLUSION: Preschool-based interventions showed some early improvements in eating habits and PA. Evidence is limited by the small number of studies, a lack of methodological quality, and inconsistencies among outcome measures. Evidence regarding anthropometric measurements is still inconclusive.

Latin American immigrant parents and their children's teachers in U.S. early childhood education programmes.

For many immigrants, their children's schools offer their first sustained interaction with the major societal institutions of their new countries, and so exploring the ways in which immigrant parents manage their children's educational experiences offers insight into how they adapt to new cultural norms, customs and expectations and how they are treated in return. This study delved into the involvement of Latin American immigrant parents in U.S. education, shifting the traditional focus down from elementary and secondary school to early childhood education. Statistical analysis of nationally representative data revealed that Latina immigrants had lower frequencies of most home- and community-based involvement behaviours than U.S.-born and foreign-born parents of varying racial/ethnic backgrounds but higher frequencies of involvement behaviours requiring participation in early childhood education programmes. As a window into these national patterns, qualitative data from an early childhood programme in an immigration-heavy state revealed that Latina immigrant mothers and their children's teachers often talked about each other as partners in supporting children's educational experiences but that their actual interactions tended to socialise mothers into being more passive recipients of teachers' directives.

Effectiveness of a coordinated community effort to promote early literacy behaviors.

The purpose of this study is to report on the effectiveness of a coordinated, community-wide intervention to promote early literacy behaviors with low-income parents, especially parents with limited English language proficiency. The interventions include book distribution programs that were based in clinical settings, childcare centers and home visitation programs. The intent of these interventions was to communicate a message that reading to infants and young children and accessing services at the public library are beneficial. The methodology involved in the administration of a Community Based Parental Survey (CBPS) included questions related to early literacy behaviors in order to evaluate the effectiveness of these efforts. Two independent samples collected in 2001 and 2003 were compared. The data comparison between the two time periods showed a 77% increase in parents reporting that they showed books to their infants on a daily basis. There was also a 71% increase in parents reading books aloud to their children on a daily basis. Other indicators also improved. Establishing an early reading ritual encourages infants to have an association to books, helps in language acquisition and supports the social and emotional connection between a parent and his or her young child. The act of holding an infant and reading to him/her on a consistent basis can improve health literacy and hopefully improve student reading achievements. Early interventions like these are relatively low cost and can yield considerable long term results. We conclude that multi-level community based interventions show positive trends in promoting early literacy behaviors.

Development and initial validation of the Spanish form of the adjustment scales for preschool intervention (ASPI).

The purpose of the study was to develop and validate a Spanish language form of the Adjustment Scales for Preschool Intervention (ASPI) for use by early childhood teachers. A multi-step, mixed method adaptation and translation process of the English form was used to increase the cultural relevance, linguistic comparability, and metric equivalence of the measure in its Spanish language form. Exploratory and confirmatory factor analyses in a diverse sample of preschool children from low-income families (N = 4077) revealed two higher order behavioral dimensions of Overactivity and Underactivity. ASPI dimension scores across Spanish and English language forms were horizontally equated through IRT. Criterion-related validity using multilevel models was established through concurrent associations with social, emotional, behavioral, and academic readiness skills. Policy and practice applications, and future directions for the use of scale scores are discussed.

Do Black and Hispanic children benefit more from preschool? Understanding differences in preschool effects across racial groups.

Recent studies suggest that the effects of attending preschool vary by race. These findings are difficult to interpret because the likelihood of enrolling a child in preschool also differs across groups. This study used newly released, nationally representative data to examine whether the impact of preschool participation at age 4 varies across racial groups after accounting for selection differences (N = 7,400). Among a subsample of children living below a poverty threshold, no racial differences in preschool impact are detected. However, findings suggest that nonpoor Black children benefit substantially more from preschool than their nonpoor White or Hispanic peers. Implications of these findings are discussed toward understanding the potential of large-scale preschool interventions for narrowing racial achievement gaps.

Causal attributions in Early Childhood Education: A new categorization system.

BACKGROUND: From Early Childhood Education onwards, causal attributions influence explanations of school performance. We performed a systematic review of the available knowledge (1970-2019) about Weiner's (1986) Attribution Theory of the Motivation of Achievement in order to examine studies related to the causal attributions of success and failure at school. We found numerous empirical studies related to Bernard Weiner's theory. However, little research exists about students in Early Childhood Education. Therefore, the aim of this study was to identify the causes to which children attribute their successes and failures during this educational period. METHOD: A sample of 200 students aged between 3 and 6 years old was selected. To collect the data, an individually implemented Piagetian clinical interview was used. RESULTS: A large volume of qualitative information was collected for classification which exceeded Weiner's traditional causal attributions. Creating a category to group all new attributions implied losing too much information under a non-specific label. CONCLUSION: A new categorization of the causal attributions was designed, made up of 10 categories -adapted to the 3-6 years age range- which revises and expanding on the categorization created by Weiner.

Automatized analysis of children's exposure to child-directed speech in reschool settings: Validation and application.

The present study explored whether a tool for automatic detection and recognition of interactions and child-directed speech (CDS) in preschool classrooms could be developed, validated, and applied to non-coded video recordings representing children's classroom experiences. Using first-person video recordings collected by 13 preschool children during a morning in their classrooms, we extracted high-level audiovisual features from recordings using automatic speech recognition and computer vision services from a cloud computing provider. Using manual coding for interactions and transcriptions of CDS as reference, we trained and tested supervised classifiers and linear mappings to measure five variables of interest. We show that the supervised classifiers trained with speech activity, proximity, and high-level facial features achieve adequate accuracy in detecting interactions. Furthermore, in combination with an automatic speech recognition service, the supervised classifier achieved error rates for CDS measures that are in line with other open-source automatic decoding tools in early childhood settings. Finally, we demonstrate our tool's applicability by using it to automatically code and transcribe children's interactions and CDS exposure vertically within a classroom day (morning to afternoon) and horizontally over time (fall to winter). Developing and scaling tools for automatized capture of children's interactions with others in the preschool classroom, as well as exposure to CDS, may revolutionize scientific efforts to identify precise mechanisms that foster young children's language development.

Academic Outcomes of School-Aged Children Born Preterm: A Systematic Review and Meta-analysis.

Importance: Children born preterm are at an elevated risk of academic underachievement. However, the extent to which performance across domain-specific subskills in reading and mathematics is associated with preterm birth remains unclear. Objective: To conduct a systematic review and meta-analysis of academic outcomes of school-aged children born preterm, compared with children born at term, appraising evidence for higher- and lower-order subskills in reading and mathematics. Data Sources: PubMed/MEDLINE, PsycINFO, and the Cumulative Index of Nursing and Allied Health Literature electronic databases from January 1, 1980, to July 30, 2018, were searched for population, exposure, and outcome terms such as child (population), preterm birth (exposure), and education* (outcome). Study Selection: Peer-reviewed English-language publications that included preterm-born children and a comparison group of term-born children aged 5 to 18 years and born during or after 1980 and that reported outcomes on standardized assessments from cohort or cross-sectional studies were screened. Of the 9833 articles screened, 33 unique studies met the inclusion criteria. Data Extraction and Synthesis: Data were analyzed from August 1 to September 29, 2018. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. Two reviewers independently screened the databases and extracted sample characteristics and outcomes scores. Pooled mean differences (MDs) were analyzed using random-effects models. Main Outcomes and Measures: Performance on standardized assessment of higher-order subskills of reading comprehension and applied mathematics problems; lower-order reading subskills of decoding, pseudoword decoding, and word identification; and lower-order mathematics subskills of knowledge, calculation, and fluency. Results: Outcomes data were extracted for 4006 preterm and 3317 term-born children, totaling 7323 participants from 33 unique studies. Relative to children born at term, children born preterm scored significantly lower in reading comprehension (mean difference [MD], -7.96; 95% CI, -12.15 to -3.76; I2 = 81%) and applied mathematical problems (MD, -11.41; 95% CI, -17.57 to -5.26; I2 = 91%) assessments. Across the assessments of lower-order skills, children born preterm scored significantly lower than their term-born peers in calculation (MD, -10.57; 95% CI, -15.62 to -5.52; I2 = 92%), decoding (MD, -10.18; 95% CI, -16.83 to -3.53; I2 = 71%), mathematical knowledge (MD, -9.88; 95% CI, -11.68 to -8.08; I2 = 62%), word identification (MD, -7.44; 95% CI, -9.08 to -5.80; I2 = 69%), and mathematical fluency (MD, -6.89; 95% CI, -13.54 to -0.23; I2 = 72%). The associations remained unchanged after sensitivity analyses for reducing heterogeneity. Conclusions and Relevance: These findings provide evidence that preterm birth is associated with academic underperformance in aggregate measures of reading and mathematics, as well as a variety of related subskills.

From pills to programs: lessons from medicine for developing effective lifestyle interventions.

OBJECTIVE: To propose a scheme for comprehensive development and evaluation of lifestyle interventions. METHODS: We adapted the four-phase system used in drug development, the engine of progress in medicine for decades, to construct a system for developing lifestyle intervention programs. RESULTS: Phase I: The intervention is constructed and tested with a small number of individuals. Acceptability and feasibility are assessed. Evaluation is primarily qualitative. Phase II: Effectiveness on intermediate endpoints (e.g. behavior) is tested in a real field setting, with a limited number of individuals, using a before-and-after design. An iterative process of testing and refinement may be necessary. Phase III: The effectiveness of the intervention on health-related outcomes is tested, using, where possible, a randomized design. Phase IV: Large-scale implementation and penetration are assessed in other populations. Process variables and local and national health indicators are studied. The development and evaluation of our hygiene intervention, which took place in Jerusalem from 1999 to 2001, is presented as a case study. CONCLUSIONS: Adaptation of the phased system of drug development to lifestyle interventions is a conceptually simple approach to building effective, sustainable programs for community-based public health.

[Comparative analysis of the efficacy of a playful-narrative program to teach mathematics at pre-school level]. / Análisis comparativo de la eficacia de un programa lúdico-narrativo para la enseñanza de las matemáticas en Educación Infantil.

Comparative analysis of the efficacy of a playful-narrative program to teach mathematics at pre-school level. In this paper, the effectiveness of a programme comprising several components that are meant to consolidate mathematical concepts and abilities at the pre-school level is analyzed. The instructional methodology of this programme is compared to other methodologies. One-hundred 5-6 year-old children made up the sample that was distributed in the following conditions: (1) traditional methodology; (2) methodology with perceptual and manipulative components, and (3) methodology with language and playful components. Mathematical competence was assessed with the Mathematical Criterial Pre-school Test and the subtest of quantitative-numeric concepts of BADyG. Participants were evaluated before and after the academic course during which they followed one of these methodologies. The results show that the programme with language and playful components is more effective than the traditional methodology (p<.000) and also more effective than the perceptual and manipulative methodology (p<.000). Implications of the results for instructional practices are analyzed.

Emotional labor strategies and job burnout in preschool teachers: Psychological capital as a mediator and moderator.

BACKGROUND: Preschool teachers can easily become exhausted and worn out, otherwise known as job burnout. Studies have explored the effects of emotional labor strategies and psychological capital on job burnout; however, few have examined their trilateral relationship, especially the role of psychological capital with respect to emotional labor strategies and job burnout. OBJECTIVE: This study explored the mediating and moderating effects of psychological capital in the relationship between three kinds of emotional labor strategies and job burnout in preschool teachers. METHODS: A cross-sectional study was conducted among preschool teachers in China. A total of 355 preschool teachers completed a self-report questionnaire, including three scales that measured emotional labor strategies, psychological capital, and job burnout. Resultant data were analyzed based on correlations, multiple regressions, and structural equation modeling. RESULTS: Results showed that for preschool teachers, two emotional labor strategies (deep acting and expression of natural emotion) were found to be negatively correlated with psychological capital and positively correlated with job burnout. However, surface acting was positively correlated with psychological capital and negatively correlated with job burnout. Psychological capital partially mediated the effects of the three emotional labor strategies on job burnout. Additionally, psychological capital significantly moderated the effects of surface acting and deep acting on job burnout. CONCLUSIONS: Psychological capital can significantly mediate and moderate the effects of emotional labor strategies on job burnout.
