Peer communication patterns were assessed as school-aged boys participated in a dyadic referential communication task. The responses of comparison boys were compared to those of hyperactive boys on methylphenidate (Ritalin) and on placebo in a double-blind crossover design. 2 separate systems for assessing communication were developed, a qualitative system designed to capture the "flavor" of interaction and a quantitative system focused on specific types of communicative content. Task products and completion times were also scored. The results suggest that hyperactive children, regardless of medication status, are less likely than comparison peers to (a) modulate ongoing or habitual behavior patterns in response to externally imposed shifts in role-appropriate behaviors; (b) maintain consistent, uninterrupted goal orientation; and (c) respond to subtle social learning opportunities. In this situation, methylphenidate appeared to have a greater impact on behavioral style than on competence, decreasing perceived intensity without influencing efficiency. A mild medication-induced dysphoria was also documented. Directions for future research and the need for caution in clinical interpretation are discussed.  相似文献

Demands for accountability, tighter fiscal policies and political pressures required many post-secondary institutions in the early 1980s to seek new strategies for improving their cost efficiency. Advances in communication technology were perceived by some institutions as a means of maintaining and even diversifying services at minimal cost. Although positive economic returns often appeared attractive, educational benefits were frequently less than anticipated. Misunderstanding, poor communication and insufficient information, as well as professional conservatism, resistance to change and support for traditional practices, tended to prevent contemporary communication systems from being applied extensively in higher education.  相似文献

The relationship between a Midwest church-affiliated institution and its supporting congregations provides an opportunity to investigate part of the sociological environment within which a college-choice decision is made for students of a strong denominational orientation. Applying the local-cosmopolitan dichotomy used by previous researchers, this study hypothesized that the cultural orientation of local congregational leaders reflects norms that are aligned to congregational enrollment support or nonsupport for the denominational university. The findings demonstrate that the concepts of cultural, social, and ecclesiological localism-cosmopolitanism are helpful in explaining an individual's support for the denominational university. Also, differing cultural orientations among congregational leaders are related to the degree to which the congregation supports the university with the enrollment of youth.  相似文献

Abstract

Environmental education (EE) scholars view intergenerational learning as a means to influence adult understandings of and relationships with the environment. Yet EE researchers have studied intergenerational learning in a limited fashion, with no emphasis on its role in higher education. The purpose of this article is to use feminist posthumanist theories to broadly explore intergenerational learning in critical food studies courses taught at the university level. We rely primarily on student coursework and post-course interviews as data sources that convey student perceptions of interactions with their families and the natural world, demonstrating how students develop relational identities shaped by personal experience as well as experiences in the course. To conclude, we discuss both the limitations and implications of this research for the field of EE.  相似文献

The expectations, attributions, and reactions toward children and youth who have contracted HIV/AIDS warrant close attention from parents, teachers, related service personnel, and others who will interact with these students in the schools. Those who are misinformed or unaware of their beliefs may inadvertently discriminate against children and youth with the disease. This study examined factors that influence judgments about children and youth with HIV/AIDS in a sample of teacher education students. Course of infection of HIV accounted for significant differences in the participants' judgments about responsibility and blame for contracting the disease and also fearfulness and attitudes reflecting isolation for these youth. Educational professionals should be aware of the many negative attributions placed on adolescents who are diagnosed as HIV+ and be prepared to act as facilitators when designing appropriate interventions to assist these students. © 2004 Wiley Periodicals, Inc.

The purpose of this article is to inform researchers and practitioners about potential challenges in the selection, administration, and interpretation of results of measures of vocabulary assessment when working with deaf and hard-of-hearing children. This article reviews methods that can be used to assess vocabulary of children through the age of 5 years, including naturalistic observation, parent report measures, and standardized vocabulary tests. The authors also describe procedures to assess word-learning processes available to children to facilitate vocabulary acquisition. General cautions regarding the use of assessment tools with deaf and hard-of-hearing children are reviewed, as well as cautions for specific assessment measures. Finally, based on available research, suggestions are offered regarding what each assessment test can tell us about deaf and hard-of-hearing children's vocabulary development.  相似文献

This preliminary study explores the effects ofusing CTELL (Case Technologies EnhancingLiteracy Learning) cases on preserviceteachers' learning. Students participated inone of three instructional treatments:traditional, traditional plus video, andtraditional plus CTELL cases. A pre-postconcept web, describing students' understandingof effective reading instruction, served as themajor outcome measure. This was supplementedwith a unidimensional confidence measure,journal entries, and student interviews. Nosignificant differences were found for any ofthe three treatment conditions on the conceptmapping task or the confidence measure.However, the journal entries and interview datahighlight important issues, challenges andbenefits, with respect to the use of multimediacases. Implications for teacher education areexplored.  相似文献

This paper introduces and evaluates four practical multidimensional linking procedures that are based on the theoretical framework recently proposed by Davey, Oshima, and Lee (1996): (a) the Direct method, (b) the Equated Function method, (c) the Test Characteristic Function (TCF) method, and (d) the Item Characteristic Function (ICF) method. The evaluation was conducted using simulated data. As anticipated, the competing procedures yielded different linking parameter estimates. The TCF and ICF methods were found to be more stable and recovered the true linking parameters better than the other two methods. Furthermore, all procedures were found to be acceptable under almost any of the minimization criteria and offered dramatic improvement over not linking at all. It is recommended that the choice of a linking procedure should depend on the purpose of linking.  相似文献
