Abstract

Since the 1990s, there has been a growing recognition of the importance of the out-of-school context for children and adolescents. Fueled in part by family demographics that include substantial numbers of employed mothers and single mothers, in part by concerns about poor academic performance and problem behaviors, and in part by intensified efforts to find ways to promote positive youth development, researchers and practitioners have focused their attention on two particular out-of-school settings: after-school programs and structured activities. The research findings pertaining to full-time (i.e., 5 days a week) after-school programs are mixed, which may reflect the substantial heterogeneity of the programs in terms of children being served, the types of activities offered, and the training and background of the staff. The federal funding of the 21st Century CLCs and various state and local initiatives has increased the numbers of low-income and English-learning students participating in after-school programs. A substantial number of programs are becoming more school-like. The available research suggests that (under some conditions) attending after-school programs is linked to improved social and academic outcomes. Children are more likely to show academic and social benefits when staff-child relationships are positive and nonconflictual, when programs offer a variety of age-appropriate activities from which children can select those of interest, and when children attend on a regular basis. The research findings about voluntary structured activities are more straightforward. Participation in these activities has been consistently linked to positive academic and social developmental outcomes in numerous studies. What appears to be key is that the activities are voluntary, are characterized by sustained engagement and effort, and provide opportunities to build or develop skills. Although the available research has begun to inform our understanding of the out-of-school context, further research is sorely needed. First, there is a need for research to identify the social, cognitive, and linguistic processes by which participation in programs and structured activities influences child and youth developmental outcomes. For example, researchers need to consider the competitiveness of sport activities in relation to children's social and emotional functioning. Researchers also might examine after-school experiences as settings in which complex thought processes can develop. Heath (1999) has conducted initial work in the area of language development by obtaining language samples during voluntary structured activities and analyzing their content. In the initial samples, students engaged in few sustained conversations on a topic and they frequently changed topics. After 3-4 weeks at the program, however, Heath noted substantial changes in the students' conversations and language. The use of conditionals (should, would, could) increased. She also noted increases in strategies to obtain clarifications from others and increases in the use of shifted registers and genres. Heath's (1999) linguistic analyses in conjunction with research that considers social and motivational processes underscore the broader point that the out-of-school context is complex and multi-layered and likely to be of substantial importance in the lives of children and youth. Research is needed to identify other important developmental processes in programs and structured activities. A promising procedure for identifying these processes is experience sampling (Csikszentmihalyi & Larson, 1987; Larson, 1989). Experience sampling methodology allows researchers to collect systematic data about an individual's activities, thoughts, and affective states by obtaining reports from participants at multiple randomly sampled points in time. Participants are signaled to provide a report in a variety of ways, such as with beepers or alarm watches. This record of experiences is not usually captured by other data collection methods. For example, program observations provide data on observed activities, interactions, and program climate, but do not offer insights into students' feelings and experiences within the after-school environment. Questionnaire and survey data are retrospective, asking respondents to recall past experiences and feelings regarding their after-school activities. Experience sampling could be used to examine any number of processes in after-school programs and structured activities. A better understanding of the effects of program content also is needed. Whether after-school programs should focus exclusively on enrichment activities or exclusively on academic activities, or include both enrichment and academic components, is the subject of heated debate. Some after-school scholars (Halpern, 1999; Heath, 1999; Eccles, in press) have argued forcefully that a focus on academics undermines the unique strengths and role of programs, and that programs should emphasize extracurricular enrichment activities. Others (Noam, 2004) have supported the move by policy makers and educators to make programs more academic, with an emphasis on homework help, tutoring, and preparation for academic achievement tests. The effects of different approaches to after-school programming have not been evaluated systematically. Research that describes, compares, and then tests effects of different program content models is needed to determine which types of programs are successful in attracting and keeping students (a necessary condition for programs to effect change), and to determine whether different types of programs are differentially associated with improvements in student outcomes such as school attendance, academic achievement, social competencies, and behavioral adjustment. A related question is whether structured activities that are obligatory or required have the same effects as voluntary structured activities do. Researchers also should further examine the impact of different attendance patterns on child developmental outcomes. We do not have solid information about optimal intensity and duration of attendance in terms of outcomes. There are suggestions in the literature that long-term, frequent attendance at programs is associated with positive outcomes for low-income children. Research needs to examine whether these results hold for middle-income children and youth as well. Finally, experimental studies should be conducted in which children and adolescents are randomly assigned to after-school programs and structured activities. All of the research to date on structured activities, and most of the research on after-school programs, has been nonexperimental, so questions about selection bias remain. Experimental studies in which children and adolescents are randomly assigned to participation in programs and activities would be a valuable next step in understanding relations between participation and child and youth outcomes. Such research should not be conducted until we have more information about the components of high-quality programming in terms of program content and developmental processes, however.

摘要

自20世纪90年代以来,人们越来越认识到校外环境对儿童和青少年的重要性。部分原因是家庭人口结构的变化,包括大量就业母亲和单身母亲;部分原因是对学业成绩不佳和问题行为的担忧;部分原因是为促进青少年积极发展而加大了寻找方法的力度,研究人员和从业者将注意力集中在两个特定的校外环境上:课后项目和结构化活动。关于全日制(即每周5天)课后项目的研究结果好坏参半,这可能反映了这些项目在服务对象、提供的活动类型以及工作人员的培训和背景方面存在很大的异质性。21世纪社区学习中心的联邦资金以及各种州和地方的倡议增加了低收入和英语学习学生参与课后项目的人数。大量项目正变得越来越像学校。现有研究表明,(在某些情况下)参加课后项目与改善社会和学业成果有关。当师生关系积极且无冲突时,当项目提供各种适合年龄的活动供儿童选择感兴趣的活动时,以及当儿童定期参加时,儿童更有可能在学业和社交方面受益。关于自愿结构化活动的研究结果则更为直接。在众多研究中,参与这些活动一直与积极的学业和社会发展成果相关联。关键似乎在于这些活动是自愿的,其特点是持续参与和努力,并提供培养或发展技能的机会。尽管现有研究已开始增进我们对校外环境的理解,但仍迫切需要进一步研究。首先,需要进行研究以确定参与项目和结构化活动影响儿童和青少年发展成果的社会、认知和语言过程。例如,研究人员需要考虑体育活动的竞争性与儿童社会和情感功能的关系。研究人员还可以将课后经历视为复杂思维过程得以发展的环境进行考察。希思(1999年)通过在自愿结构化活动期间获取语言样本并分析其内容,在语言发展领域开展了初步工作。在最初的样本中,学生很少就一个话题进行持续的对话,而且他们经常改变话题。然而,在项目进行3至4周后,希思注意到学生对话和语言有了显著变化。条件句(应该、会、能够)的使用增加了。她还注意到向他人寻求澄清的策略有所增加,以及转换语域和体裁的使用有所增加。希思(1999年)的语言分析以及考虑社会和动机过程的研究强调了一个更广泛的观点,即校外环境是复杂且多层次的,在儿童和青少年的生活中可能具有至关重要的意义。需要进行研究以确定项目和结构化活动中其他重要的发展过程。一种有前景的识别这些过程方法是经验抽样法(奇克森特米哈伊和拉森,1987年;拉森,1989年)。经验抽样方法使研究人员能够通过在多个随机抽样的时间点从参与者那里获取报告,收集有关个人活动、思想和情感状态的系统数据。通过传呼机或闹钟等多种方式向参与者发出信号以提供报告。这种经验记录通常不会被其他数据收集方法所获取。例如,项目观察提供了关于观察到的活动、互动和项目氛围的数据,但无法洞察学生在课后环境中的感受和经历。问卷调查数据是回顾性的,要求受访者回忆他们对课后活动过去的经历和感受。经验抽样可用于研究课后项目和结构化活动中的任何数量的过程。还需要更好地了解项目内容的影响。课后项目应该只专注于丰富活动还是只专注于学术活动,或者包括丰富和学术两个组成部分,这是激烈辩论的主题。一些课后项目学者(哈尔彭,1999年;希思,1999年;埃克尔斯,即将出版)有力地辩称,专注于学术会削弱项目的独特优势和作用,项目应该强调课外丰富活动。其他人(诺姆,2004年)支持政策制定者和教育工作者使项目更具学术性的举措,重点是家庭作业帮助、辅导和学业成绩测试准备。尚未系统评估课后项目不同方法的效果。需要进行描述、比较然后测试不同项目内容模式效果的研究,以确定哪些类型的项目在吸引和留住学生方面取得成功(这是项目实现变革的必要条件),并确定不同类型的项目是否与学生成果的改善存在差异关联,如出勤率、学业成绩、社交能力和行为调整。一个相关问题是强制性或必修的结构化活动是否与自愿结构化活动具有相同的效果。研究人员还应进一步研究不同出勤模式对儿童发展成果的影响。就结果而言,我们没有关于最佳出勤强度和持续时间的确切信息。文献中有建议称,长期、频繁参加项目对低收入儿童有积极影响。研究需要考察这些结果是否也适用于中等收入儿童和青少年。最后,应该进行实验研究,将儿童和青少年随机分配到课后项目和结构化活动中。迄今为止关于结构化活动的所有研究以及关于课后项目的大多数研究都是非实验性的,因此关于选择偏差的问题仍然存在。在我们获得更多关于高质量项目在项目内容和发展过程方面的组成部分的信息之前,不应进行此类实验研究。
