This research examined the impact of the first‐year implementation of an instructional intervention to promote achievement and equity in science and literacy for culturally and linguistically diverse elementary students. The research addressed three areas: (a) overall science and literacy achievement, (b) achievement gaps among demographic subgroups, and (c) comparison with national (NAEP) and international (TIMSS) samples of students. The research involved 1,523 third‐ and fourth‐grade students at six elementary schools in a large urban school district. Significance tests of mean scores between pre‐ and posttests indicate statistically significant increases on all measures of science and literacy at both grade levels. While achievement gaps widened with third graders on some of the measures, the gaps tended to narrow with fourth graders. The results based on item‐by‐item comparisons with NAEP TIMSS samples of students indicated overall positive performance of the students in the research at the end of the school year. © 2005 Wiley Periodicals, Inc.

Children''s Expectations of the Outcomes of Social Strategies: Relations with Sociometric Status and Maternal Disciplinary Styles   总被引：1，自引：0，他引：1  

Craig H. Hart  Gary W. Ladd  Brant R. Burleson 《Child development》1990,61(1):127-137

To explore relations between maternal disciplinary styles, children's expectations of the outcomes of social strategies, and children's peer status, 144 mothers and their first- (N = 59) and fourth- (N = 85) grade children (ages = 70-86 months and 116-129 months, respectively) participated in home interviews prior to the beginning of the school year. Measures of children's sociometric status were obtained in classrooms after the school year began. Results indicated that children of mothers who were more power assertive in their disciplinary styles tended to be less accepted by peers and tended to expect successful outcomes for unfriendly-assertive methods for resolving peer conflict (e.g., threatening to hit another child). In addition, children who expected unfriendly-assertive strategies to lead to self-oriented gains were less accepted by peers. Moreover, maternal disciplinary styles and outcome expectations for unfriendly-assertive strategies were found to make separate and independent contribution to peer status.  相似文献   

Towards creating an inclusive community of researchers: the first three years of the North American Association for Environmental Education research symposium     

Ronald B. Meyers  Michael Brody  Justin Dillon  Paul Hart  Marianne Krasny  Martha Monroe 《Environmental Education Research》2007,13(5):639-661

This article uses a series of interlinked, personal vignettes to discuss the first three years of the North American Association for Environmental Education research symposium, from the perspectives of the key organizers. Seven challenges in the field of environmental education research are identified in a recent historical context, and we illustrate how the symposium sought to address them. The challenges were, that: (i) environmental education research has been marginalized in some areas and not recognized in others; (ii) environmental education research and environmental education practice need to be brought closer together; (iii) environmental education research is still in early development of a professional perspective; (iv) environmental education research has to give a voice to early career scholars and graduate students; (v) environmental education research needs to enable discourse about both process and outcomes; (vi) environmental education researchers need social learning contexts to help develop professional identities and create more meaningful dialogue to address these challenges; and (vii) methodologies, theoretical frameworks and differences in beliefs in environmental education research need to be accommodated. The last challenge is seen as the most significant with which to continue to engage, in developing open, inclusive forums for researchers of environmental education.  相似文献   

Educational Media: innovation and evaluation     

A. Hart 《Learning, Media and Technology》1988,14(3):201-212

Reliance on the power of audiovisual media in nurse education has substantially increased in the last few years. This has been especially so when changing approaches to patient care have required large‐scale innovations in clinical and educational practice. Successful innovation depends on effective educational provision and audiovisual media such as videotape and videodisc have been expected to act as powerful agents in this process. Yet there has been little research on the effectiveness of such media. This article examines what actually happened when the multi‐media package Who Cares? (1983) was used in the United Kingdom. The package consisted of two video films and a teacher's handbook.

All known users of the package in the United Kingdom were followed up in order to establish what sort of people used it, in what contexts, how its use was organised and how effective it was for learners. This article explores how the specific educational contexts in which media are used play a vital role in making learning effective. Relevant theory is examined to provide a model of how teachers and learners use media. The results of the research are closely related to recent developments in education and training and, finally, practical recommendations are made for improving the efficiency and effectiveness with which modern educational media are used.  相似文献   

Social acknowledegments for children with disabilities: effects of service dogs     

B Mader  L A Hart  B Bergin 《Child development》1989,60(6):1529-1534

While service dogs are known to perform important tasks for people using wheelchairs, such as retrieving dropped items or pulling a wheelchair, they may also serve as an antidote for social ostracism. Adults in wheelchairs have been found to receive many more social acknowledgements when a service dog is present than when not. This study examined whether disabled children in wheelchairs with service dogs receive more frequent social acknowledgment than when no dog is present. Behaviors of passersby in response to children in wheelchairs were recorded in shopping malls and on school playgrounds. In both settings, social acknowledegments (e.g., friendly glances, smiles, and conversations) were substantially more frequent when a service dog was present. Social effects of the dog were more pronounced in shopping malls, typical of unfamiliar settings where the child would be likely to experience being ignored or overlooked. Service dogs may assist in normalizing the social interactions for children with disabilities producing social isolation.  相似文献   

Exploring the Co‐Development of Reading Fluency and Reading Comprehension: A Twin Study          下载免费PDF全文

Callie W. Little  Sara A. Hart  Jamie M. Quinn  Elliot M. Tucker‐Drob  Jeanette Taylor  Christopher Schatschneider 《Child development》2017,88(3):934-945

This study explores the co‐development of two related but separate reading skills, reading fluency and reading comprehension, across Grades 1–4. A bivariate biometric dual change score model was applied to longitudinal data collected from 1,784 twin pairs between the ages of 6 and 10 years. Grade 1 skills were influenced by highly overlapping genetic and environmental factors. Growth in both skills was influenced by highly overlapping shared environmental factors. Cross‐lagged parameters indicated bidirectional effects, with stronger effects from fluency to comprehension change than from comprehension to fluency change.  相似文献

Explaining the Resurgence of U.S. Competitiveness: The Rise of Wintelism     

Jeffrey A. Hart  Sangbae Kim 《The Information Society》2002,18(1):1-12

What explains the resurgence of U.S. international competitiveness in the 1990s? The previous decade can be characterized as one of intense U.S. concern about its declining international competitiveness. In this article, we argue that U.S. industry adopted a new industrial paradigm called "Wintelism" in response to competitive pressures from western Europe and East Asia. The essence of Wintelism is a reliance on open but owned technical standards and extensive outsourcing of component production to enable industrial structures to become less vertically and more horizontally integrated. Countries like the United States that pursued a modified regulatory state approach to structuring state-societal relationships found it easier to adopt this new paradigm than countries that pursued the developmental state approach.  相似文献   

Perspectives of mentoring: The Black female student-athlete     

Akilah R. Carter  Algerian Hart 《Sport Management Review》2010,13(4):382-394

The purpose of this study was to understand Black female collegiate athletes’ perception of mentors and the characteristics of their current mentors. Understanding their definition of a mentor and the persons whom fulfill the psychosocial and career mentor roles will provide insight on the mentor–mentee relationship. In addition, the researchers found it necessary to ascertain the persons whom fulfill the athletic mentor role due to the collegiate athletic status. This study is approached from a critical feminist lens, utilizing a qualitative questionnaire to capture and analyze the voice and perceptions of the Black female athletes (n = 38) from two Division I universities. Critical race theory and Black feminist thought were employed to capture the “multiple jeopardies” of the Black female athlete, thus recognizing race, or racism, and gender, or sexism, are at the fore of their daily experiences. The findings revealed Black female athletes’ definitions of a mentor were characterized by the traditional mentor qualities such as a guide, a supporter, and a role model. Further analysis indicated the women had three distinctly different persons to fulfill each mentor dimension to include: career/academic support, psychosocial support, and athletic support. However, the characteristics of those persons who fulfilled each dimension were family members, with greater influence by the coach on the athletic support dimension. Based on the findings it would benefit administrators to recognize these characteristics and persons of influence when providing support services and developmental programs for the Black female collegiate athlete.  相似文献   

Differential results of instruction at the preoperational/concrete operational transition     

Robert Pasnak  Alice Hansbarger  Shannon L. Dodson  Julie B. Hart  John Blaha 《Psychology in the schools》1996,33(1):70-83

The same cognitive intervention was attempted with children from two schools serving different populations. All children were identified by their teachers as having cognitive difficulties in kindergarten. Within each school, children were randomly assigned to experimental and control groups. Children in the experimental groups received more than 40 short lessons on unidimensional classification (oddity), seriation, and number conservation. These lessons were taught via a learning-set procedure employing 160 kinds of manipulatable objects. Children in the control groups received an equal amount of instruction on verbal and mathematics materials recommended by their teachers. Five months after the instruction was concluded, the experimental group in one school scored significantly better on a psychometric test of reasoning. There was no significant difference in verbal and mathematics achievement. Differences in the significance of outcomes of the intervention at the two schools suggest that children at different stages of cognitive development will benefit differently from cognitive interventions. © 1996 John Wiley & Sons, Inc.  相似文献
