The purpose of this study is to examine how children's starting level and development of social competence (i.e., task orientation and peer sociability) during kindergarten and first grade predict gifted program enrollment by third grade, even after considering children's cognitive ability. A second purpose is to examine the extent to which the relationship between children's social competence and gifted program enrollment differs depending on children's socioeconomic status (SES), ethnicity, and gender. Latent growth curve analyses conducted on 347 children revealed that students enrolled in gifted programming were not only those high in cognitive ability, but also those showing early task orientation. Neither peer sociability's initial status nor growth was a significant predictor of gifted enrollment. Multigroup comparisons demonstrated different predictive paths for higher versus lower SES groups. Implications are discussed including important questions raised by this study and the need for teacher training in the identification of giftedness. © 2008 Wiley Periodicals, Inc. 相似文献

The world-wide use of digital storage and communications devices is increasing the need to make texts available in multiple languages. In this article we explore the possibility of storing a compressed form of a translated version of a text, taking advantage of the availability of the original text. The original text provides some of the semantic content of the text that is to be compressed, and therefore makes it possible for compression to be more efficient than if that information were not available. We begin with an experiment to evaluate the information content of a text when a parallel translation is available. This is achieved by having human subjects guess texts letter by letter, with and without a parallel translation. The perceived information content of a text can be determined from the way subjects make their guesses. The design and results of this experiment are described. The main conclusion is that while the text is considerably more predictable with the aid of a parallel translation, there is a surprising amount of information introduced by the translation. Insights obtained from this experiment are then applied in the design of a mechanical system for compressing parallel texts. The system stores one translation of a text intact, and then compresses further translations of the text with the aid of the original. The method described is able to compress texts significantly better than is possible without the aid of a parallel text. Aspects of the design are also applicable to future compressors that might take advantage of the semantic content of a text to obtain better compression. 相似文献

ABSTRACTResearch suggests that a significant reason that a large number of students earn low grades in the fundamental engineering science course Statics is that they may be entering the course with incorrect conceptual knowledge of mathematics and physics. The self-explanation learning approach called collective argumentation helps k-12 students to understand their misconceptions of mathematical principles that often appear abstract to them. This study investigated collective argumentation as an instructional approach that helps engineering students identify and correct their misconceptions of topics taught in Statics. Results suggest that argumentation improves student performance as measured by grades earned on semester exams. Survey and focus group results suggest that students did not understand the argumentation process. Therefore, the students did not like using it as a learning approach. 相似文献

Today with the rise in the number of 3- to 6-year-old children enrolled in center-based early childhood programs, and a focus on program quality, it becomes imperative for educators to have a better understanding of the role research plays in establishing high-quality programs as these programs provide much of the foundation that supports early learning and development (Child Trends, 2014). Although psychology, and the role of child development research in particular, has always been integral to the field of early childhood education beginning with the seminal works of Piaget, Bronfenbrenner, Bruner, and others (Lickona,1971), the field had never fully embraced the use of research to inform practice, until the 1990s. This had been, in part, because the field of early childhood education originally viewed itself as a field of practitioners that provided for the everyday care and needs of young children, whereas it viewed child development researchers as scientists who paid little attention to the practical needs of classroom teaching (Takanishi, 1981). Although, today, there is no longer this ideological divide between the two areas, with the child development research being used to inform educational practice and policy (Center for the Developing Child, 2007), nevertheless there still remains a gap in the ability of educators to effectively implement evidence-based practices. Given the increased focus on providing young children with access to high-quality education, and the need for teachers to implement evidence-based practices the present paper attempts to bridge the gap by providing a brief overview of the science of early childhood development, its importance for development of early learning standards, and an overview of the Early Learning Toolkit which was developed to provide early learning educators guidance and resources to support the implementation of early learning standards within their own states as well as well across the nation. The goal of this article is to bridge theory and practice in early childhood education. 相似文献

This study investigated how an authentic assessment program was used to examine student learning outcomes within the context of a Christian university’s institutional mission, core values, and distinctive qualities. For the purposes of this study, an authentic assessment program is defined as assessing student-produced work within the context of the institutional mission. A sample of 1,814 undergraduate students taking one or more general education courses at the university during the 2007–2009 academic years was examined for any significant differences in student learning outcomes. A univariate analysis of covariance (ANCOVA) indicated the Student Assessment System (SAS) scores for the online students were not significantly different from the SAS scores for the face-to-face (F2F) students after controlling for course grade. These results suggest that online students achieved the same critical mission-related educational outcomes that the university required of its F2F students. An implication of this finding is that the university just as effectively articulated its faith-based mission and vision to the online students as it did to its students taking classes F2F. 相似文献

The use of IQ scores and discrepancy formulas for identifying specific learning disabilities (SLD) has been widely discredited by prominent researchers for more than a decade. Nevertheless, the overwhelming majority of state policies still specify the use of discrepancy formulas, including the simple difference method, which is psychometrically inferior to regression-based methods. This study compares the use of a minimum IQ cutoff score and a simple difference method versus a regression-based method for identifying SLD in a sample of African American and European American full-time college students (N = 117). Replicating the findings from previous studies using typically achieving children, typically achieving adults, and school-age children with SLD, this study adds to the chorus of voices criticizing the use of outdated assessment practices that can have deleterious effects for individuals with SLD. The implications for legislative policy are discussed in the context of the historical overrepresentation of African Americans in all special education categories except SLD and the increased access to higher education that students with SLD have gained during the past decade. 相似文献

This paper describes an effort to develop a survey instrument capable of measuring important aspects of adolescents’ experiences of interest-related pursuits that are supported by technology. The measure focuses on youths’ experiences of connected learning (Ito et al. in Connected learning: an agenda for research and design. Digital Media and Learning Research Hub, Irvine, 2013), an emerging model of learning across settings supported by digital media. Specifically, the instrument aims to measure the depth with which youth are able to engage in an interest-related pursuit, the level of support and encouragement they receive from peers, and the degree to which their pursuit involves performance or media production as an essential feature. The survey also elicits information regarding the connections between youths’ interest-related pursuits and academic goals, the involvement of adults as co-participants in pursuits, and youths’ access to technology tools they deem necessary for their pursuits. The paper reports on results from a pilot study and two rounds of field-testing, in which we evaluated the validity and reliability of the instrument and compared results with evidence from interviews with youth. Our aim was to investigate the feasibility of an approach to measuring youths’ interest-related pursuits to inform future research and evaluation of initiatives focused on digital media and learning. 相似文献
