An early admission procedure is the first step in adjusting formal educational programming to meet the educational, social, and emotional needs of intellectually advanced children. In view of the benefits to the child and potential benefits to society of meeting the intellectually advanced child's needs, it is important that school systems establish early admission policies. This article presents 12 guidelines for processing an early admission applicant.  相似文献

Canonical variate analysis of the relationships between teachers' ratings of children's behavior and an index of teacher-pupil compatibility objectively demonstrated a significant relationship between behaviors representative of serious psychopathology and teacher-pupil compatibility. Previous multivariate analyses of variance had failed to identify meaningful relationships between teacher-pupil compatibility and teacher nomination of a child as a behavior problem. This study provides inferential support for the contention that school behavior problems and emotional disturbances are separate nosological entities.  相似文献

Lifelong learning is receiving greater attention due to population aging in modern societies. Lifelong learning benefits individuals by supporting their physical, psychological, social, and economic well-being. However, older adults generally have lower motivation for learning than younger adults, and facilitating long-term participation in learning activities is still challenging. Previous studies mainly identified negative factors such as barriers and obstacles to individuals’ initial participation in lifelong learning programs. As such, less is known about positive factors that promote long-term participation. To address this gap, data were collected from 330 older adults who participated in the Osher Lifelong Learning Institute program in an urban community in the United States. Results from proportional odds ordinal logistic regression analysis demonstrated that gender, number of household members, income, religious affiliation, self-rated health, and number of courses taken were associated with satisfaction with the program. In hopes to promote true lifelong learning, possible explanations about the findings are explored and several recommendations for existing lifelong learning programs are derived in this study.  相似文献

Student behavioral problems pose a myriad of challenges for schools. In this study, we examine the relations among teacher and school‐level constructs (i.e., teacher collaboration, supervision/discipline, instructional management), and student‐related outcomes (i.e., high‐risk behaviors, barriers to learning, student social–behavioral climate). Teachers across 29 high schools, in a large urban school district serving primarily low‐income students, completed self‐report surveys. Multilevel regression was used to test both individual‐ and school‐level predictors of student outcomes. Findings suggest that teacher practices at the individual and school levels are linked to student high‐risk behaviors, barriers to student learning, and school climate. More specifically, findings indicate that better supervision/discipline and instructional management are associated with fewer high‐risk behaviors and barriers to learning. More instructional management is also linked to positive social–behavioral climate. Results from this study highlight the association between teacher practices and a range of student‐related problem behaviors, and suggest that system‐level interventions in the school may have positive effects.  相似文献

In this article, an inclusive treatment package for children with ADHD, The ADHD Classroom Kit (Kit), is described. Components of the Kit are categorized in three areas: consequences for appropriate behavior, consequences for inappropriate behavior, and peer-mediated interventions. The empirical rationale for each component of the Kit is discussed. Also, a case study of a 6-year-old girl (Carol) with reported disruptive behavior problems is presented as preliminary data supporting the Kit's effectiveness. An A-B-A reversal design was used in Carol's classroom. Mean frequencies of appropriate behavior were 61.3% (baseline), 78.5% (Kit), and 70.7% (reversal). In addition, mean frequencies of on-task behavior were 76.2% (baseline), 87.8% (Kit), and 82.5% (reversal). Implications for future research and practice with the Kit are addressed. © 1998 John Wiley & Sons, Inc.  相似文献

ABSTRACT

This paper considers the examination results of TVEI and non TVEI pupils in the database established at the University of Newcastle in 1985‐87. The pupils took national exams in the summer of 1987, when they were about 16 years old. Their average grades (Exam Means) and their accumulated grades (Exam Totals) were considered separately.

The Exam Mean and Exam Total scores were generally worse for TVEI than non TVEI pupils, even when pupils with the same ability test scores and aspirational scores were compared. However, it is possible that non TVEI factors caused the discrepancy in results and it is these factors which are the subjects of this paper.

The paper considers firstly whether the differences are an artefact of regression analysis. Secondly, the data are considered using various multilevel models. Both analyses suggest that there was no TVEI effect on the Exam Mean score and a negative TVEI effect on the Exam Total. Various explanations for these findings, concerning internal school allocational and curriculum policies, are considered and discussed.  相似文献

This forum response extends the argument made by Avery and Hains that oral traditions can be useful for including the cultures and contexts of rural areas within science instruction. To buttress the oral expressions presented in Avery and Hains, I compare oral expressions of a second rural area, 600 miles to the South, in Eastern North Carolina. I explore similarities and differences in expressions from the two areas and consider the changing rural context within Eastern North Carolina. I add a consideration of larger demographic shifts impacting many rural areas—particularly in the US South—and close with a discussion of implications for science education.  相似文献

OBJECTIVE: To determine whether there is an age-specific incidence of hospitalized cases of Shaken Baby Syndrome (SBS) that has similar properties to the previously reported normal crying curve, as a form of indirect evidence that crying is an important stimulus for SBS. DESIGN AND SETTING: The study analyzed cases of Shaken Baby Syndrome by age at hospitalization from hospital discharge data for California hospitals from October 1996 through December 2000. PATIENTS: All cases of children less than 18 months (78 weeks) of age for whom the diagnostic code for Shaken Baby Syndrome (995.55) in the International Classification of Disease, Ninth Edition, Clinical Modification was assigned. RESULTS: There were 273 hospitalizations for SBS. Like the normal crying curve, the curve of age-specific incidence starts at 2-3 weeks, has a clear peak, and declines to baseline by about 36 weeks of age. In contrast to the normal crying curve that peaks at 5-6 weeks, the peak of SBS hospitalizations occurs at 10-13 weeks. CONCLUSIONS: The age-specific incidence curve of hospitalized SBS cases has a similar starting point and shape to the previously reported normal crying curve but the peak occurs about 4-6 weeks later. Of the likely predisposing causes, this pattern is only consistent with the properties of early crying. There are numerous explanations for the lag in the peaks between crying and SBS hospitalizations, including the possibility of repeat shakings prior to hospitalization. The importance of crying as a stimulus to SBS may provide an opportunity for preventive intervention.  相似文献
