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

Objective. This study investigated how parents’ perceptions of, feelings toward, and anticipated responses to children’s emotions relate to parents’ meta-emotion philosophy and attachment. Design. Parents (112 mothers and 95 fathers) completed an online research study where they viewed photographs of unfamiliar girls and boys (aged 10–14 years) displaying varying intensities of happiness, sadness, fear, anger, and neutral expressions. Parents labeled the emotion, identified the emotion’s intensity, and reported their mirrored emotion and responses. They also completed measures assessing their meta-emotion philosophy and attachment. Results. Meta-emotion philosophy predicted parents’ responses to children’s negative emotion, in that greater emotion-coaching predicted greater accuracy in labeling emotions (boys only), a greater likelihood to interact with children, and for mothers to be further from the mean in either direction in their mirrored emotion. Attachment also predicted parents’ responses to children’s negative emotions: Parents higher in anxiety reported more mirrored emotion, and those higher in avoidance reported less mirrored emotion, lower intensity, and less willingness to interact (boys only). In exploratory models for positive emotion, parents’ meta-emotion philosophy did not predict their responses, but parents higher in attachment avoidance rated girls’ positive emotions as less intense, reported less mirrored emotion, less willingness to interact, and less supportive responses, and those higher in anxiety showed the opposite pattern. Conclusion. Despite methodological limitations, results offer new evidence that parents’ ratings on a standardized emotion perception task as well as their anticipated responses toward children’s emotion displays are predicted by individual differences in their attachment and meta-emotion philosophy.  相似文献

This article reports on findings from a year-long research project conducted during the 2012–2013 school year in a PK–12 school district, located in the Mountain West region of the United States, utilizing the Photovoice method. The findings in the project point to the important critical counter-narratives Spanish-speaking immigrant parents present to the larger school community when given the opportunity to have their voices and perspectives heard and recorded in written form. The article provides teachers, counselors, administrators, and support staff in schools and school districts with insight into the hopes and aspirations of Spanish-speaking immigrant parents and highlights educational practices that address issues of equity and access, as seen through the eyes of the participants in the study.  相似文献

University Counseling Centers (UCCs) experience high clinical demands and severe client presentations leaving counselors with limited time and resources to evaluate delivery of services. In this article, we present clinician-friendly quality improvement (QI) strategies used at a large Midwestern university and provide recommendations for implementing QI programs at other UCCs even as their resources may vary. With counselor-led efforts examining and evaluating services, UCCs can use QI programs to inform and improve counseling practices as well as advise university administrators about the positive outcomes of the center’s work.  相似文献

It can be argued that agricultural science is one of the original forms of science education. However, over the past century, agricultural science education has habitually been perceived as an educational venue meant solely for production agriculturalists. When examining modern agricultural education we find it to be a minority within the broader field of science education, contradicting its historically stout scientific standing within the sciences. This educational shift leaves one to ponder the historic development of contemporary agricultural education. To gain deeper insight into these questions we reviewed the historical evolution of agricultural education within the United States. We then examined the professional habitus, or cultural nuances, associated with contemporary agricultural education. Next, we considered potential outcomes associated with the profession embracing post-modern perspectives within mainstream science and community-based education. Finally, we call for critical venues within agriculture education to question the status quo and challenge the acceptance of commonly held views.  相似文献
