The present study assesses the genetic and environmental etiologies of reading, rapid naming (RN), and their covariation by
fitting multivariate structural equation models to data from 587 twin pairs in which at least one member of the pair exhibited
reading difficulties (low-range) and from 360 control (normal-range) twin pairs who were tested in the Colorado Learning Disabilities
Research Center. Results from a bivariate phenotypic analysis with two hypothesized latent factors, READ and RN, indicated
that the correlation between reading and rapid naming performance for the low-range sample was significantly higher than that
of the normal-range sample. When this model was partitioned to include estimates of genetic, shared environmental, and nonshared
environmental influences, resulting heritability estimates did not differ significantly for the low-range and normal-range
samples for either READ or RN. However, similar to the phenotypic correlation, the genetic correlation between the READ and
RN latent factors could not be equated for the two groups. Thus, the etiology of the relationship between reading performance
and rapid naming may differ for children with reading difficulties and normally-achieving readers. Moreover, these results
support previous findings that the best predictors of reading skills may differ for samples of children with normal reading
levels and those with reading difficulties. 相似文献

Gesture has privileged access to information that children know but do not say. As such, it can serve as an additional window to the mind of the developing child, one that researchers are only beginning to acknowledge. Gesture might, however, do more than merely reflect understanding-it may be involved in the process of cognitive change itself. This question will guide research on gesture as we enter the new millennium. Gesture might contribute to change through two mechanisms which are not mutually exclusive: (1) indirectly, by communicating unspoken aspects of the learner's cognitive state to potential agents of change (parents, teachers, siblings, friends); and (2) directly, by offering the learner a simpler way to express and explore ideas that may be difficult to think through in a verbal format, thus easing the learner's cognitive burden. As a result, the next decade may well offer evidence of gesture's dual potential as an illuminating tool for researchers and as a facilitator of cognitive growth for learners themselves. 相似文献

This paper reports on efforts aimed toward the development of more effective procedures for identifying mothers who are at elevated risk for problems in parenting. We present data from two independent samples of known maladaptors and corresponding comparison mothers and report on our attempts to cross-validate a promising screening instrument composed of items that index social support and parenting attitudes. The resultant 20-item scale correctly identified over 90% of maladaptive and comparison mothers. When this scale was cross-validated on a second independent sample of maladaptors and comparison mothers, it was again almost 90% accurate. Issues concerning the field application of this promising instrument are discussed and its possible limitations are considered. 相似文献

Using the critical work of Andreas Kazamias on the history and methods of comparative education as conceptual framework, we investigate the education (over a 200-year period) of the Slovak Roma. We position our story as paradigmatic of the dual processes of enlightenment and obscurantism with which we are familiar in thinking about the history of racial violence. The article describes the encounter of a young British doctor, Richard Bright, with Roma and Slovaks in 1814, and explores the Enlightenment thinking about Roma in specific, and race in general, in Bright’s travelogue. We juxtapose these historical investigations with qualitative findings from research conducted recently in the same region of Slovakia. Our goal is to show that Kazamias’s calls for a return to the historical in educational research, and greater attention to the “paideia of the soul,” have relevance in considering the discouraging past and present of Roma in Slovak schools and society. 相似文献

This paper describes and analysies the use of a delphi research methodology to assess faculty perceptions of institutional needs and goals in an osteopathic medical education program. Use of the delphi to educate faculty in the administrative and political functioning of the institution as well as to involve all faculty in the refinement of specific needs and goals is discussed. Full‐time clinical and basic science faculty of the New Jersey School of Osteopathic Medicine provided an example of the varied uses of the delphi research methodology in higher education and specifically in profesiional higher education. The three rounds of the delphi procedure produced faculty consensus on the following institutional variable items: (a) the philosophical and functional orientation of the curriculum; (b) location and design of the physical campus facilities and environment; (c) faculty issues of tenure, promotion, salary and merit; (d) teaching, and the evaluation of teaching; (e) student characteristics and admissions policies; and (f) administrative structure and communication networks. 相似文献

Recent research has examined the role of vocational-technical training in facilitating the transition from school to work of adolescents with learning disabilities. The present study provided 6-, 12-, and 24-month follow-up data on such students who had attended vocational-technical programs. Matched groups of students without disabilities from vocational-technical programs, as well as randomly selected students without disabilities from regular high schools, were also included for comparisons. Results of the study raised several questions about the value and purpose of vocational-technical training for adolescents with learning disabilities. 相似文献
