Class Size and Educational Policy: Who Benefits from Smaller Classes?

ABSTRACT

The impact of class size on student achievement remains an open question despite hundreds of empirical studies and the perception among parents, teachers, and policymakers that larger classes are a significant detriment to student development. This study sheds new light on this ambiguity by utilizing nonparametric tests for stochastic dominance to analyze unconditional and conditional test score distributions across students facing different class sizes. Analyzing the conditional distributions of test scores (purged of observables using class-size specific returns), we find that there is little causal effect of marginal reductions in class size on test scores within the range of 20 or more students. However, reductions in class size from above 20 students to below 20 students, as well as marginal reductions in classes with fewer than 20 students, increase test scores for students below the median, but decrease test scores above the median. This nonuniform impact of class size suggests that compensatory school policies, whereby lower-performing students are placed in smaller classes and higher-performing students are placed in larger classes, improves the academic achievement of not just the lower-performing students but also the higher-performing students.     

Collaborative Treatment for Sexual Behavior Problems in an Adolescent Residential Center

Abstract

Many residential treatment and sex offender programs for adolescents historically have used coercion-based interventions. Treatment programs employing coercive techniques often replicate the same destructive and intrusive behaviors they seek to eliminate. Tension between departments coupled with poor communication and discomfort around sexual behavior issues within the staff of residential treatment centers are more likely to inhibit the progress of the youths they serve.

Collaboration among residential, educational, and clinical components enables staff to work in a direct, genuine, and respectful fashion with students who have histories of sexually abusive behavior. It further assists in maintaining a safe and predictable environment for these students. Finally, it helps students eliminate destructive behaviors by directly and consistently addressing four key areas: sexually abusive behavior, antisocial attitudes, social/emotional functioning, and overall self-care. It is not the author's intention to hold Bennington School, Inc.up as a model residential treatment program or to criticize other residential facilities. Rather, it is hoped that what is working in Bennington may be helpful to others.

Many who have worked on the front lines of residential treatment with sexually abusive adolescents have received training in elements specific to sexually abusive behavior. The origins of treatment for youth who have sexually abused were noteworthy for their lack of offense-specific interventions (National Adolescent Perpetration Network, 1993). However, a wealth of literature soon emerged addressing the need for assessment and treatment techniques specific to this population (Perry & Orchard, 1992; Barbaree, Marshall & Hudson, 1993). Much of this literature made assumptions regarding high levels of chronicity (Perry & Orchard,1992) while other contributions stressed the role of denial and minimization (Barbaree & Cortoni, 1993). As a result, while many issue-specific forms of assessment and treatment were developed, they often did not take into account other developmental needs and issues in the lives of sexually abusive youths (Lane, 1997).

Concurrent with this emerging research was a substantial increase in the number of treatment programs for juvenile sex offenders (National Adolescent Perpetration Network, 1993). In this context, it is not surprising that many treatment programs relied heavily on treatment targeting denial, minimization, and perceived sexual deviance without taking into account other treatment needs of youths. Although a recent literature review of adolescent residential programs (Curwen, 2000) notes a trend away from shame-based approaches, there appears to be less clarity on specific criteria on which to base residential treatment of adolescents who have sexually abused (Curwen, 2000).

Finally, recent research shows that among adult populations, accepting responsibility for abusive behavior in treatment is more likely to result from a warm, genuine, and empathic treatment style (Marshall, Fernandez, & Anderson, 1999). Group therapy participation, similarly, results from encouragement, open questions, and nonconfrontational challenge. The emerging themes of recent trends and research should inspire those at the front lines of residential treatment to reconsider not just basic treatment approaches, but the most minute elements of their interactions with youths.     

处理大学城学生群体性突发事件重要问题的思考

近年来,大学城学生群体性突发事件时有发生,产生原因多种多样。一旦对其处置不当,就会影响到大学城的正常教学、生活秩序,乃至于社会稳定。因此在处理此类事件时应注意多方机构协调运行,善于把握时机,快速稳定事态,并通过发挥学生干部、党员、教师的话语作用积极疏导,安定学生情绪,坦诚沟通以此增强事件的透明度,且辅以良好的善后工作,最终达到巩固成果、防止事件反复发生的目的。

RCBDs with a control

The randomized complete block designs, RCBDs, are among the most popular of block designs for comparing a set of experimental treatments. The question of this design's effectiveness when one of the treatments is a control is examined here. Optimality ranges are established for the RBCD in terms of the strength of interest in control comparisons. It is found that if the control treatment is of secondary interest, the RCBD, when not best, is typically near best. This is not so when comparisons with the control are of greater interest than those among the other treatments.     

城镇化背景下农村群体性事件的防范与治理

研究指出，当前我国正积极稳妥推进新型城镇化，着力提高城镇化质量。然而在城镇化过程中由于多元利益矛盾的交集没有得到及时有效的疏解，从而导致农村群体性事件爆发的规模和数量呈现出上升趋势，使新型城镇化的任务面临着严峻的挑战。因此剖析新时期农村群体性事件的现状与产生原因，建立有效的防范与治理机制，是顺利推进新型城镇化的有力保障与重要内容。     

试论政府在新型农村合作医疗中的责任

由政府在新型农村合作医疗中承担主导责任有其深厚的政治学、经济学、法学与社会学基础。然而,在新型农村合作医疗制度的建立过程中,政府在制度建设、财政投入、管理体制和宣传教育等方面存在诸多问题,这就需要进一步转变观念,提高认识,完善相关制度建设、加大财政投入力度、强化管理以及政府的引导、宣传与沟通作用。     

A combination multiple comparisons and subset selection procedure to identify treatments that are strictly inferior to the best

This paper considers the problem of identifying which treatments are strictly worse than the best treatment or treatments in a one-way layout, which has many important applications in screening trials for new product development. A procedure is proposed that selects a subset of the treatments containing only treatments that are known to be strictly worse than the best treatment or treatments. In addition, simultaneous confidence intervals are obtained which provide upper bounds on how inferior the treatments are compared with these best treatments. In this way, the new procedure shares the characteristics of both subset selection procedures and multiple comparison procedures. Some tables of critical points are provided for implementing the new procedure, and some examples of its use are given.
