Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.

A technique is presented for partitioning N students into K groups of fixed sizes using a given measure of proximity for all student pairs. The measure of proximity is typically calculated from a set of variables, such as completed curriculum units or learning style, and constitutes the data needed for a criterion of partition fit. This latter index is explicitly defined by the sum of within-group proximities and when used in conjunction with the optimization procedure discussed, homogeneous groups can be obtained that satisfy externally imposed size requirements. Finally, a simple generalization is suggested for the related task of grouping students to meet upper limit size constraints only. 相似文献

Male albino rats were run in a discrete-trial two-bar operant analog of the double alley. Completion of a FR 4 response chain on the first bar was rewarded 50% of the time for the 12 experimental Ss, but was never rewarded for the 12 control Ss. Both groups received consistent reward at the end of a FR 4 chain on the second bar. Eighty-four trials were given at a rate of four trials per day. A significantly faster rate of responding on the second bar was found following nonrewarded first-bar ratios than following rewarded first-bar ratios. This frustration effect was not attributable to response depression, since the nonrewarded performance of the experimental group exceeded that of the control group. 相似文献

Because access to new technologies is unequally distributed, there has been considerable debate about the growing gap between the so‐called information‐rich and information‐poor. Such concerns have led to high‐profile information technology policy initiatives in many countries. In Australia, in an attempt to ‘redress the balance between the information rich and poor’ by providing ‘equal access to the World Wide Web’ (Virtual Communities, 2002), the Australian Council of Trade Unions, Virtual Communities (a computer/software distributor) and Primus (an Internet provider) in late 1999 formed an alliance to offer relatively inexpensive computer and Internet access to union members in order to make ‘technology affordable for all Australians’ (Virtual Communities, 2002). In this paper, we examine four families, one of which had long‐term Information and Communication Technologies (ICT) access, and three of which took advantage of the Virtual Communities offer to get home computer and Internet access for the first time. We examine their engagement with ICT and suggest that previously disadvantaged family members are not particularly advantaged by their access to ICT. 相似文献

Across the country, states are reporting increases in the number of children with autism enrolled in the education system. Although a few specific treatment methods have been established as efficacious for some children with autism in controlled settings, research examining the translation of these treatments into early intervention programs has been minimal. The current study examined provider self-reports of the use of interventions in community settings through focus groups. Providers report the use of both evidence-based and non-evidence-based techniques and indicate that they often combine and modify these techniques based on child, personal, and external factors. Few providers had a clear understanding of evidence-based practice, and all providers reported concerns about adequate training. Implications for early intervention research are discussed. 相似文献

This article examines the complex connections between literacy practices, the use of information and communication technologies (ICTs) and disadvantage. It reports the findings of a year-long study which investigated the ways in which four families use ICTs to engage with formal and informal literacy learning in home and school settings. The research set out to explore what it is about computer-mediated literacy practices at home and at school in disadvantaged communities that makes a difference in school success. The findings demonstrate that the 'socialisation' of the technology--its appropriation into existing family norms, values and lifestyles--varied from family to family. Having access to ICTs at home was not sufficient for the young people and their families to overcome the so-called 'digital divide'. The article concludes that old inequalities have not disappeared, but are playing out in new ways in the context of the networked society. 相似文献

An approach to essay grading based on signal detection theory (SDT) is presented. SDT offers a basis for understanding rater behavior with respect to the scoring of construct responses, in that it provides a theory of psychological processes underlying the raters' behavior. The approach also provides measures of the precision of the raters and the accuracy of classifications. An application of latent class SDT to essay grading is detailed, and similarities to and differences from item response theory (IRT) are noted. The validity and utility of classifications obtained from the SDT model and scores obtained from IRT models are compared. Validity coefficients were found to be about equal in magnitude across SDT and IRT models. Results from a simulation study of a 5-class SDT model with eight raters are also presented. 相似文献

Researchers investigating answer changing have consistently found the preponderance of changes on objective items to be from wrong to right, but little is understood about the mechanisms involved in this phenomenon. In this study, personal interviews were combined with instruction in answer-changing research to investigate further the processes involved in answer changing. Students changed answers and gained from changing, with those in the upper two thirds of the classes gaining the most. Each test-taking strategy produced a mean gain, but particular strategies were not significantly correlated with percentage of gain or percentage of change. Most students reported changing answers for thoughtful reasons such as rereading, rethinking, or remembering more information; very few changes were due to clerical errors. For each reason, most changes were wrong-to-right. We conclude that reconsideration of test items is probably underestimated in answer-changing studies. The role of memory should be considered in why people change and in how successful they judge their changing to have been. 相似文献

To what extent do students and teachers hold similar beliefs about excellent teaching? Do differences in beliefs have practical implications (e.g., how students rate their teachers on end-of-semester evaluation forms)? In Study 1, undergraduate students (N=414) and faculty members (N=128) responded to questionnaires assessing their perceptions of an excellent discussion leader, lecturer, or instructor. Participants judged items that contributed to a Structure composite as more characteristic of excellent lecturers than excellent discussion leaders and items that contributed to a Process composite as more characteristic of excellent discussion leaders than excellent lecturers. Results for students and teachers showed several systematic differences. In Study 2,278 students and their course teachers rated the characteristics of a hypothetical excellent lecturer. In addition, students rated the effectiveness of their individual teachers. Students’ ratings of their teachers were higher when students and teachers agreed on their perceptions of characteristics of excellent lecturers. 相似文献
