Data from the Early Childhood Longitudinal Study, Kindergarten Cohort were used to examine the extent to which early parenting predicted African American children's kindergarten social–emotional functioning. Teachers rated children's classroom social–emotional functioning in four areas (i.e., approaches to learning, self‐control, interpersonal skills, and externalizing behaviors). Mothers completed self‐report questionnaires assessing their home‐based parenting practices (i.e., warmth and home learning stimulation). Hierarchical regression analyses revealed that mothers who engaged in more frequent home learning stimulation (e.g., shared book reading) had children with more positive teacher ratings of approaches to learning, self‐control, interpersonal skills, and fewer externalizing behaviors. Notably, demographic characteristics also contributed to children's social–emotional functioning. Specifically, African American girls from more affluent, two‐parent homes with highly educated mothers had the most positive ratings of classroom social–emotional functioning across all four dimensions.  相似文献

Chocolate chip cookies are used to illustrate the importance and effectiveness of control charts in Statistical Process Control. By counting the number of chocolate chips, creating the spreadsheet, calculating the control limits and graphing the control charts, the student becomes actively engaged in the learning process. In addition, examining and interpreting the control charts within the context of the cooking making process encourage the student to think critically in order to solve problems.  相似文献

The rise in globalisation studies in comparative education places neo-institutional theory at the centre of many debates among comparative education researchers. However, uncertainty about how to interpret neo-institutional theory still persists among educational comparativists. With this uncertainty comes misinterpretation of its principles, variations and explanatory power. Two problematic misconceptions prevail: (1) the belief that the ‘world culture’ strand is the only version of neo-institutional theory applicable to comparative education research; and (2) the assumption that the global homogenisation of society, culture and schooling is a goal of researchers applying neo-institutional theory to comparative education phenomena. This article addresses these misconceptions, elucidating neo-institutional theory and its applicability to comparative education research. Our findings suggest that neo-institutional frameworks for comparative education research are useful, but that complementary approaches and methods are also necessary.  相似文献

Given the continued issue of student retention for online classes, past research has suggested several “retention strategies” focused on engaging students as a way to reduce their withdrawal rate from these classes. However, a recent study testing the effects of these strategies on retention in online undergraduate business courses (Leeds et al., Int J Manage Educ 7(1/2), 2013) did not show empirical support for the effectiveness of such strategies. Taking an alternative approach that focuses on individual characteristics of students, this study takes a broader view and examines previous research literature on traditional face-to-face classes to determine how individual characteristics of students may be associated with the likelihood of withdrawal from online classes. Using a sample of undergraduate students (n = 2,314) from a large state university, results from this study identified prior performance in college classes (cumulative GPA) and class standing (senior vs. non-senior) as significant student characteristics related to student retention in online classes for all students. Other factors significantly related to retention rates for students with certain characteristics or within certain majors include previous withdrawal from online courses, gender, and receipt of academic loans.  相似文献

Research Findings: Home literacy involvement (e.g., shared book reading) has been linked to enhanced cognitive development and school readiness during early childhood. Furthermore, precursory reading and math skills are key predictors of high school achievement. This study examined prospective relations between Mexican mothers’ English proficiency, their home literacy involvement, and their children's school readiness (i.e., preschool reading and math scores). A large, nationally representative sample of preschool-age Mexican American children (N = 826) was used to test a theoretically derived path analysis that demonstrated that mother-reported home literacy involvement mediated the relation between mother-reported English proficiency and children's reading achievement, but not math. Results were evident even after key family and child characteristics were controlled. Practice or Policy: Findings suggest that Mexican American children's early education and development may be enriched by family literacy programs that enhance their mothers’ English proficiency and increase the frequency of home literacy activities.  相似文献

Research Findings: This study utilized a large sample (N = 750) of 2-parent families from the Early Childhood Longitudinal Study–Birth Cohort to examine the contributions of African American fathers' home literacy involvement, play activities, and caregiving at 24 months to children's reading and math achievement in preschool. After family characteristics and child characteristics were controlled for, both mother and father characteristics predicted child achievement. Mother age predicted math achievement but not reading. Furthermore, even after mother predictors were entered into the hierarchical regressions, fathers' education and home literacy involvement also significantly predicted achievement. African American fathers who engaged in more frequent shared book reading, telling stories, singing songs, and provided more children's books in their homes at 24 months had children with better reading and math scores in preschool. Practice or Policy: These findings support growing evidence that fathers contribute to child development. Implications for research on early academic achievement in ethnically diverse samples are discussed.  相似文献

Over the past 10 years the publishing industry has undergone major changes with the shift from format driven print publishing to the dynamic delivery of information to users in a variety of digital and printed formats. These changes have affected all aspects of the publishing business including the technology platforms and product development processes. This paper will survey these areas and discuss (1) The principals of the information delivery platforms powering the new generation of products; (2) Strategies for innovation and product development including; (a) Innovation Hubs: enabling new products while maintaining the core; (b) Data driven publishing: the complete picture of your users and markets; (c) Contextual delivery to better deliver information beyond the traditional touch points of publishing and research. These strategies will allow publishing and information provider organizations to reinvent themselves in the continuing digital revolution and are key to bringing new vitality to the ever-changing role of publisher and information provider.  相似文献

Abstract

In this study, we investigated the age-related differences in repeated-sprint ability and blood lactate responses in 134 youth football players. Players from the development programme of a professional club were grouped according to their respective under-age team (U-11 to U-18). Following familiarization, the participants performed a repeated-sprint ability test [6 × 30-m sprints 30 s apart, with active recovery (2.0–2.2 m · s?1) between sprints]. The test variables were total time, percent sprint decrement, and post-test peak lactate concentration. Total time improved from the U-11 to U-15 age groups (range 33.15 ± 1.84 vs. 27.25 ± 0.82 s), whereas no further significant improvements were evident from U-15 to U-18. No significant differences in percent sprint decrement were reported among groups (range 4.0 ± 1.0% to 5.5 ± 2.1%). Post-test peak lactate increased from one age group to the next (range 7.3 ± 1.8 to 12.6 ± 1.6 mmol · l?1), but remained constant when adjusted for age-related difference in body mass. Peak lactate concentration was moderately correlated with sprint time (r = 0.70, P > 0.001). Our results suggest that performance in repeated-sprint ability improves during maturation of highly trained youth football players, although a plateau occurs from 15 years of age. In contrast to expectations based on previous suggestions, percent sprint decrement during repeated sprints did not deteriorate with age.  相似文献

Abstract

When athletes are placed into annual age groups to organize and coordinate sport participation, certain (dis)advantages occur as a result of the subtle age differences within these groups. These differences, termed “relative age effects”, have been consistently related to youth and adult sport attainment. However, there has been a lack of consistency in the terminology used in this area of research. In this paper, we consider the operational terms used in relative age research, discuss appropriate applications of terminology, and suggest directions for future research. Importantly, we argue for a unified understanding of what “relative age” means, stressing the need for clarity in directing future advances in the field.  相似文献
