SYNOPSIS
Objective . Most parents manage some degree of parenting stress without serious concerns, but young mothers experience parenting stress at higher levels than adult mothers; high parenting stress is problematic due to its association with children’s socioemotional and behavior problems and the increased likelihood of maltreatment. Understanding the circumstances that precipitate or mitigate parents’ stress can have lasting impacts for child well-being. Extant research fails to account for both longitudinal and individual variation in young mothers’ parenting stress, leading to equivocal findings about the nature of mothers’ parenting stress trajectories across early childhood. Design . The present study used growth mixture modeling (GMM) to model the trajectories of 544 first-time young mothers’ parenting stress from children’s infancy to school-age. We considered how protective factors (i.e., social support) and psychological vulnerabilities (i.e., depression) experienced during the transition to parenthood were associated with parenting stress trajectories and variation within trajectories when children were of school-age. Results . GMM identified three trajectories of parenting stress: “low stable”, “high increasing”, and “high decreasing.” Protective factors were related to low and decreasing patterns of parenting stress, whereas psychological vulnerabilities were associated with higher parenting stress patterns. Conclusions . This study has implications for programs and services that help young mothers cope with the demands of parenting and reduce parenting stress. 相似文献

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic. 相似文献

Listening and reading comprehension can be assessed by analyzing children’s visual, verbal, and written representations of
their understandings. “Talking Drawings” (McConnell, S. (1993). Talking drawings: A strategy for assisting learners. Journal of Reading, 36(4), 260–269 is one strategy that enables children to combine their prior knowledge with the new information derived from
an expository text and “translate” those newly-acquired understandings into other symbol systems, including an oral discussion
with a partner, a more detailed drawing, and written labels for the drawing. The Talking Drawings strategy begins by inviting
children to create pre-learning drawings. These initial drawings are a way of taking inventory of a child’s current content
knowledge about a particular topic. After pre-learning drawings are created and shared, children listen to or read an expository
text (e.g., information book, passage from a textbook) on the same topic as their drawing. Pairs of students discuss the information
and either modify their pre-learning drawings to be more detailed or create completely new drawings that reflect the recently-acquired
information. Students are encouraged to label their drawings with words in a diagram or schematic fashion. By evaluating the
“before” and “after” artwork, educators can identify advances in students’ reading and listening comprehension of the terminology,
facts, and principles on a particular topic. 相似文献

Cesarean birth rates in the United States reached a high of 27.6% in 2003, a 6% increase over 2002. A cultural conflict appears to exist between the views of those who believe that birth is normal and many cesareans are unnecessary and the views of those who feel that higher rates are justifiable. Childbirth educators can share cultural concepts of normal birth in their classroom. 相似文献

A universal lack of attention to the professional learning needs of teacher educators is the driver for this study, which considers the most effective ways to support the professional learning of higher education-based teacher educators. At a time when many industrialised countries are engaged in systemic educational reform, this study provides an international and comparative needs analysis through a survey of 1158 higher education-based teacher educators in the countries participating in the International Forum for Teacher Educator Development: Belgium, Ireland, Israel, the Netherlands, Norway and the UK. Our results suggest that while teacher educators are only moderately satisfied with their professional development experiences, a strong desire exists for further professional learning. This desire, influenced by their professional context, relates to their current beliefs concerning ‘best practice’ in teacher education, the academic skills required to further their professional careers and knowledge of the curriculum associated with their fields of expertise. 相似文献

The purpose of this study was to review and analyze effective classroom reading practices for early graders, using information gathered from the existing content-general and content-specific observation protocols measuring teachers’ classroom reading practices. Dimensions and constructs from 28 observation studies were synthesized to identify classroom instructional practices that have positive impacts on student achievement. Findings revealed that (a) instructional support, emotional support, and classroom management have positive impacts on student achievement, (b) the degree to which instructional practices are effective depends on students’ particular learning needs, and (c) students’ entering skills and primary language are associated with instructional effectiveness in reading. Challenges and implications for future research on effective instructional strategies for special education and the development of an observational protocol for special education teacher effectiveness are discussed. 相似文献

Although there is now a considerable literature on gender inequality in education and employment, there is virtually no research on the Careers Service which provides a bridge between the two. Based on a national survey of all Careers Services conducted in 1987, this paper explores the significance afforded to gender discrimination and the nature and content of equal opportunities policies designed to counter it. It draws attention to the differences in meaning which the term ‘equal opportunities’ can have and to the changing context in which equal opportunities policies now operate. 相似文献
