The disruption of the biological family unit due to divorce or separation followed by remarriage or re-partnering has a profound impact on every family member, including extended family members. An individual becomes a stepgrandparent through later life re-partnering, when an adult child becomes a stepparent, or when a stepchild becomes a parent. In order to gain a greater understanding of the communication influencing the development and maintenance of stepgrandparent roles and identity, a qualitative interpretive analysis method was employed as a guide for interviews with 41 adult stepfamily members across two generations of stepfamily membership: stepparents and stepgrandparents.  相似文献

The aim of this article is to analyse whether having experience of formative assessment during their initial teacher education courses (ITE) influences graduates’ subsequent practice as teachers. That is, if the assessment methods that university students are subject to during their learning process are then actually employed by them during their professional practice as schoolteachers. To address this issue, questionnaires were issued and focus groups were held with a sample of ITE graduates. The main results of the study are that: (1) formative and shared assessment (FSA) is not used a great deal during ITE, but is highly valued; (2) some graduates have implemented FSA in their practice as teachers, following their experience on their ITE course; and (3) significant variables are found regarding the implementation of FSA in schools (possible resistance from colleagues and/or pupils’ parents, etc.).  相似文献

This theoretical paper explores the need for enhanced, intersectional computing identity theory for the purpose of developing a diverse group of computer scientists for the future. Greater theoretical understanding of the identity formation process specifically for computing is needed in order to understand how students come to understand themselves as computer scientists. To ensure that the next generation of computer scientists is diverse, this paper presents a case for examining identity development intersectionally, understanding the ways in which women and underrepresented students may have difficulty identifying as computer scientists and be systematically oppressed in their pursuit of computer science careers. Through a review of the available scholarship, this paper suggests that creating greater theoretical understanding of the computing identity development process will inform the way in which educational stakeholders consider computer science practices and policies.  相似文献

Researchers have examined the impact of family on child literacy among low-income African American families and preschoolers considered to be at risk for not being ready for kindergarten. Quantitative studies identify family-parental variables associated with poorer literacy outcomes, whereas qualitative studies detail family practices that promote child literacy development. Addressing the limitations of social address variables in quantitative research, and the paucity of research on preschoolers in qualitative research, this study examines the home-based literacy practices of 20 low-income, African American families with preschoolers in Head Start transitioning to kindergarten. Using qualitative interviews informed by a resilience framework, we found that home-based literacy activities were carried out within teams of diverse kin who worked together to promote children's school readiness. Family literacy teams expanded the literacy resources available to preschoolers, providing a rich literacy environment for children's development. These findings contribute to our substantive understanding of literacy practices within low-income African American families, resilience theory, and culturally relevant home-school collaborations.  相似文献

As we progress in the 21st century, children learn to become proficient readers and writers of both digital and non-digital texts. Knowledge, skills, and understandings of literacy emerge through sociocultural interactions with non-digital tools (e.g., paper-printed books) and digital tools (e.g., touch screen tablets). However, debate is ongoing over the role that digital experiences play in emergent literacy development. Researchers have voiced the need to conceptualise a common framework for literacy development that considers the emergence of digital literacy skills alongside conventional literacy skills and how these skills might interact during development. This is particularly important in light of the increasing use of digital texts used by young children, such as E-books and digital games. Therefore, this paper proposes a framework that might guide research and practice by examining the relationships between emergent literacy skills, emergent digital literacy skills, and proficiency in reading and writing.  相似文献

Research Findings: Public policy has increasingly focused on expansion of preschool access for underserved students and systematic evaluation of preschool quality and students’ readiness for school. However, such evaluation is limited by a lack of thoroughly validated assessments for use with preschool populations. The present study examined the measurement and structural invariance of the Kindergarten Student Entrance Profile (KSEP) across kindergarten and prekindergarten groups to evaluate its potential use across developmental groups. Participants included 522 kindergarten and 548 prekindergarten students in central California. Invariance was tested by fitting a series of multiple-groups confirmatory factor analysis models with parameter constraints across groups. Results indicated that measurement and structural parameters of the KSEP were invariant across kindergarten and prekindergarten groups. Prekindergarten means on both Social–Emotional Readiness and Cognitive Readiness were significantly lower than kindergarten means. Practice or Policy: These results suggest that the KSEP may potentially be used with prekindergarten students to assess school readiness and inform intervention before kindergarten entry.  相似文献

Calculating Laplace transforms from the definition often requires tedious integrations. This paper provides an integration-free technique for calculating Laplace transforms of many familiar functions. It also shows how the technique can be applied to probability theory.  相似文献

This article provides a comparative analysis of accessibility of higher education across Russian regions in terms of the following three factors: the availability of admission opportunities; financial affordability; and geographic accessibility.

The study will be of interest to government agencies in higher education at various levels, analysts and researchers, as well as a wide range of readers focused on regional differences in higher education systems and policies.  相似文献

Objective. Parenting behavior is presumed to be related to the thoughts about child behavior that parents report in a controlled and explicit manner and to more implicit parent cognitions that occur outside of conscious awareness and are less accessible to verbal report. Design. We examined mothers’ attitudes toward their children as correlates of self-reported parenting behavior. We used a combination of a self-report questionnaire and a reaction-time method (the Implicit Association Test) to assess explicit and implicit attitudes, respectively. We also assessed mothers’ implicit and explicit attributions for child misbehavior in relation to parenting, using a questionnaire measure of attributions completed under high-cognitive load (implicit attributions) or under low-cognitive load (explicit attributions). Mothers of 124, 6- to 10-year-olds (52% male) participated. Results. Attitudes assessed by self-report questionnaire and the Implicit Association Test were uniquely associated with negative parenting. The cognitive load manipulation moderated associations between attributions and parenting, such that child-blaming attributions were inversely associated with positive parenting only under conditions of high-cognitive load. Conclusions. Compared to traditional self-report questionnaires, methods such as the Implicit Association Test or cognitive load manipulations may more effectively assess implicit parent cognitions.  相似文献
