Adult Interactions and Child Engagement

The purposes of this study were to investigate how engagement varied as a function of concurrent adult interactions (e.g., individual versus group orientation, type of teacher interaction) and pre-existing states (e.g., age, ratings of typical engagement). Eleven child care teachers and 63 children were videotaped in 93 naturally occurring child care situations. Two teacher interaction categories, elaborations and information giving, were associated with participatory engagement, attention, and low engagement. Interaction behaviors that were responsive without providing direction and those that were directive without responding to children were not associated with engagement. Individually targeted interactions produced more engagement than did group-targeted interactions. Chronological age, developmental age, and ratings of persistence did not statistically significantly affect engagement.     

Bystander Intervention in Cyberbullying

Cyberbullying incidents often occur in the presence of other bystanders. The inaction of bystanders can augment the deleterious effects of bullying on a victim. However, bystanders can intervene to stop a cyberbullying incident or offer support to the victim. Two studies were conducted to examine variables that were expected to influence the propensity of a bystander to take action in cyberbullying incidents: the number of bystanders, the anonymity of the bystander, and the closeness between the bystander and the victim. Results supported the diffusion of responsibility effect. A higher number of bystanders was negatively associated with bystander intervention. Moreover, the perceived anonymity of bystanders was negatively related to the propensity to intervene, and closeness with the victim was associated with a greater tendency to intervene and support the victim. Altogether, the results shed light on the interplay of context, relationships, and technology in the behavior of bystanders to a cyberbullying episode.     

Does context matter? Explicit print instruction during reading varies in its influence by child and classroom factors

This study examined preschool teachers’ (n = 59) explicit print instruction during shared reading and considered whether the benefits of this practice to children's learning (n = 379) varied as a function of the classroom environment and children's developmental characteristics. Measures of explicit print instruction and the classroom environment (global classroom quality, literacy environment) were obtained by aggregating observations taken across the 30 weeks of the study. Child outcomes were measured as spring print knowledge performance, controlling for fall. Child developmental characteristics were measured directly (language ability) and indirectly (attentional skills) in fall and winter, respectively. Findings showed that explicit print instruction contributed to children's learning, but its benefits decreased as the quality of the classroom and children's attentional skills increased. Implications for research and practice are discussed.     

Native Mexican Parents’ Beliefs About Children’s Literacy and Language Development: A Mixed-Methods Study

Research Findings. This study examined Mexican caretaker roles, beliefs, and practices around their child’s language and literacy development. Twenty-six parents in three preschools representing three socioeconomic strata located in Querétaro City, México completed questionnaires and participated in focus groups. We used convergent parallel mixed methods to analyze and compare parent questionnaire quantitative data and qualitative focus group data with a grounded theory approach to identify focus group discussion themes. Four themes were emerged: (a) Goals and expectations regarding reading and socioemotional development, (b) Perceptions and beliefs about children’s oral and written language, (c) Caretaker’s perceived role in children’s language and literacy development, and (d) Home and community learning-related resources and practices. Findings highlighted that Mexican parents highly value supporting their children’s education both socioemotionally and through engagement in literacy routines—evidence of duality in the educacíón value among native Mexican families. These literacy routines were complementary and responsive to teacher classroom instruction. Practice or Policy. Understanding how Latino families instantiate literacy practices to respond to American schooling expectations may be a way to address home-school discontinuities that often reflect lack of familiarity with the U.S. educational system.     

Overreporting and underreporting of child abuse: teachers' use of professional discretion

OBJECTIVE: According to mandatory reporting laws for professionals, the relationship between initial recognition that a child may have been abused and the subsequent reporting of that suspected case of child abuse to the responsible agency would, at first glance, appear to be clear. However, this relationship has developed into one of the major social policy controversies of the recent past. Our major goal is to present research findings that address this social policy debate concerning the problems of underreporting and overreporting, focusing specifically on teachers. METHOD: A factorial survey design, that combines the advantages of the factorial experiment with those of surveys, was employed in a probability sample of teachers (N=480) who responded to vignettes in which case characteristics were systematically manipulated. Teachers responded with judgments about whether the vignette was child abuse and the likelihood that they would report this suspected case. Characteristics of the teachers and their work setting (school) were also measured. RESULTS: When comparing the teachers' recognition and reporting scores, we found that they gave the same score for 63% of the vignettes they judged, gave higher reporting than recognition scores (overreporting) for 4% of the vignettes, and gave higher recognition than reporting scores (underreporting) for 33% of the vignettes. Discrepancies between recognition and reporting (over and under reporting) were related to characteristics of the case, teacher, and school where the teacher was employed. CONCLUSIONS: Teachers in our Ohio sample evidence the use of professional discretion in making judgments about the recognition and reporting of child abuse and do not appear to make these judgments with equal certainty. Their use of discretion is more likely to result in underreporting than overreporting.     

Child Care Subsidy and Program Quality Revisited

Research Findings: Previous research has documented conflicting results on the relationship between program quality and the percentage of children receiving subsidized child care (subsidy density) in early childhood centers. This research examined the relationship between subsidy density and the quality of infant and preschool classrooms in child care centers, taking into consideration teacher education and salary as well as other structural variables associated with quality. A multimethod evaluation was conducted with 110 child care centers utilizing an interview of center directors as well as classroom observations using standardized measures of quality and language/literacy in the classroom. Regression analyses indicate that subsidy density does not predict the quality of infant classrooms. However, subsidy density is a significant predictor of the quality of preschool classrooms. Teacher education is predictive of some quality indicators, but teacher salary is not. Practice or Policy: Practice and policy implications are discussed to promote the quality of child care centers that serve low- income children. Statewide initiatives should target centers with higher subsidy density for quality improvements. Local programs and state policy should provide teachers with opportunities to obtain additional education and then offer incentives to remain in their current early childhood settings.     

金缕梅科银缕梅属与帕罗堤属的亲缘关系——核糖体DNA ITS序列证据

本文对金缕梅科弗特吉族(Molinadendron和Matudaea除外)的细胞核核糖体DNA ITS片段进行了序列分析，在此基础上对该族的演化关系、尤其是中国特有属银缕梅属的系统位置进行了最简约分支分析。基本结果如下：其一，蚊母族和狭义的弗特吉族均不形成自己的单系分支，因此，支持Endress的处理，即合并两族为广义的弗特吉族；其二，银缕梅属同帕罗堤属有着密切的亲缘关系，支持形态学和解剖学结论；其三，根据该片段核苷酸序列的演化速率推算出的银缕梅属和帕罗堤属间分化时间为晚中新世。此结论大致与化石记录相符。     

Relations Among Maternal Literacy Beliefs, Home Literacy Practices, and the Emergent Literacy Skills of Preschoolers With Specific Language Impairment

Self-reported maternal literacy beliefs and home literacy practices were compared for families of children with typicially developing language skills (TL, n = 52) and specific language impairment (SLI, n = 56). Additionally, the present work examined whether maternal beliefs and practices predicted children's print-related knowledge. Mothers filled out 2 questionnaires asking about their literacy beliefs and practices while children's print-related knowledge was assessed directly. Results indicated that mothers of children with SLI held somewhat less positive beliefs about literacy and reported engaging in fewer literacy practices compared to mothers of children with TL. For the entire sample, maternal literacy practices and beliefs predicted children's print-related knowledge, although much of this association was accounted for by maternal education. Subgroup analyses focused specifically on children with SLI showed there to be no relation between maternal literacy beliefs and practices and children's print-related knowledge. The present findings suggest that the home literacy experiences of children with SLI, and the way that these experiences impact print-related knowledge, may differ in important ways from typical peers.     

Three-Dimensional Printing of Archived Human Fetal Material for Teaching Purposes

The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.
