AbstractStudent absenteeism is a widespread and critical issue in early childhood education. Current efforts to reduce student absenteeism in both preschool and K–12 settings have largely been family- and parent-focused interventions. Yet, interventions targeting teachers and schools may similarly be effective tools to improve student attendance. We utilize data from a large-scale, experimental evaluation of an early childhood professional development intervention to examine whether it impacted children’s absenteeism and chronic absenteeism. Although the professional development targeted the quality of teacher-child interactions and did not target children’s absenteeism, we find that the professional development reduced student absence rates by 1.0 percentage points (equivalent to approximately an additional 1.9?days of preschool). The professional development also reduced chronic absenteeism by 6.0 percentage points. Impacts were concentrated among lower-income children. Implications for policies targeting student absenteeism in preschool settings are discussed. 相似文献

Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys 下载免费PDF全文

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother–infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex‐differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the “lactational programming” hypothesis on the impact of maternal‐origin hormones ingested via milk. 相似文献

Several studies examining computer‐mediated communications (CMC) in online courses have found low levels of participation under both voluntary (ungraded) and mandatory (graded) conditions. This is troubling since student participation is widely considered to have a positive impact on performance. Program‐level data were analyzed to explore the relationship between three factors—(1) experience with previous online courses, (2) the course itself, and (3) the instructor—and subsequent participation. All three factors separately impacted participation levels in this voluntary CMC setting. Based on the findings, the authors recommend that researchers using CMC participation level as a study variable consider controlling for three global factors: previous online course experience, course, and instructor. Finally, the relationship between participation level and subsequent performance is tested, and the potential benefits of conducting future CMC research in voluntary discussion settings and with program‐level data are discussed. 相似文献

With increased demand for improved early childhood education services, it is important to better understand the essential professional development resources that have the greatest impact on both teacher and child outcomes. This study compared the effectiveness of two teacher-training models in bilingual Migrant and Seasonal Head Start and Head Start classrooms. Both conditions included the use of a technology-based student progress-monitoring tool. The progress monitoring provided detailed feedback on students’ progress 15 across the academic year and helped organize instructional groupings. The comprehensive treatment condition included biweekly professional development sessions, in-class mentoring, and provision of classroom materials, whereas the treatment-control condition included only the provision of a limited set of classroom materials. Across multiple sites in Texas, 49 pretest and posttest teacher observations and bilingual child assessments were collected on a subsample of students (n = 387). Research Findings: Improvements in teaching behaviors were observed in both experimental conditions; no significant differences were observed between teachers across conditions. Three measures of child language and literacy growth differed significantly, favoring the comprehensive treatment model, but most outcomes did not differ significantly between groups. Practice or Policy: Implications of these mixed findings and future research directions are discussed. 相似文献

In the bidirectional control procedure, observers are exposed to a conspecific demonstrator responding to a manipulandum in one of two directions (e.g., left vs. right). This procedure controls for socially mediated effects (the mere presence of a conspecific) and stimulus enhancement (attention drawn to a manipulandum by its movement), and it has the added advantage of being symmetrical (the two different responses are similar in topography). Imitative learning is demonstrated when the observers make the response in the direction that they observed it being made. Recently, however, it has been suggested that when such evidence is found with a predominantly olfactory animal, such as the rat, it may result artifactually from odor cues left on one side of the manipulandum by the demonstrator. In the present experiment, we found that Japanese quail, for which odor cues are not likely to play a role, also showed significant correspondence between the direction in which the demonstrator and the observer push a screen to gain access to reward. Furthermore, control quail that observed the screen move, when the movement of the screen was not produced by the demonstrator, did not show similar correspondence between the direction of screen movement observed and that performed by the observer. Thus, with the appropriate control, the bidirectional procedure appears to be useful for studying imitation in avian species. 相似文献

The present study investigated the effects of divorce and family relations on young children's development prospectively, using an ethnically diverse sample of approximately 300 low-income families. We also were able to examine the moderating effects of ethnicity on child adjustment in always two-parent, to-be-divorced, already-divorced, and always single-parent families. Results indicated that to-be-divorced European American and African American families demonstrated higher rates of preschool-age behavior problems, and already-divorced families showed similar trends. Parental conflict and behavior problems accounted for predivorce differences in child behavior problems, whereas rejecting parenting accounted for differences in problem behavior between always single-parent and always two-parent families. The results are discussed in terms of the importance of ethnicity in influencing young, low-income children's adjustment to different family structures. 相似文献

Through this study we compared different informants and different behavior screening tools that are available to screen for behavioral and emotional risk. We examined screening results from 100 students from a high school with a high achiever's magnet program in the Southeastern United States (school demographics: 71% female and 79% black, non-Hispanic). This school conducted behavior screening using both teacher-report via the Student Risk Screening Scale, Internalizing/Externalizing (SRSS-IE) and student report via the Strengths and Difficulties Questionnaire (SDQ). Nonparametric correlation tests were conducted between the SRSS-IE and SDQ externalizing and internalizing scores. Generalized linear regression models were created based on the data (demographics, internalizing, and externalizing scores on both screening tools) to model the two count outcomes (office discipline referrals [ODRs] and absences). Diagnostic accuracy metrics were generated from the scores on both the SRSS-IE and SDQ with the outcome measures (ODRs and absences). Externalizing scores on both screening tools had statistically significant low correlations. The ODR model contained two predictors: externalizing score on the SRSS-IE and internalizing score on the SDQ, while the absence model contained grade and the externalizing score on the SDQ. The highest accuracy and agreement values were seen between students with elevated risks on both screening measures and ODRs. The results confirmed that teacher and student reporting, as well as different screening tools, will result in some different students being identified. The choice of informant and screening tools should be dependent on the needs and resources of the school. 相似文献

The present study investigated relations between proactive and reactive functions of physical and relational aggression and functional impairment across early childhood. It was hypothesized that reactive functions of aggression would be associated with functional impairment. Hypotheses with regard to proactive functions of aggression were exploratory. Participants were 36 children (22 girls) from a longitudinal study. At Time 1 (M = 50.31 months old, SD = 10.97), observations of aggressive behavior were collected during preschool free-play. At Time 2 (M = 73.33 months old, SD = 10.88), parent-report of functional impairment was collected. Reactive physical aggression was a significant and unique predictor of future impairment when controlling for gender and all other types of aggression. Implications of these findings are discussed from a developmental perspective. 相似文献
