班级结构对留守儿童心理健康的影响:同化还是对比效应?

基于河南和陕西两省17所农村学校4~9年级103个班级内4021名学生的调查数据,分析了班级结构(一般农村儿童在班级中所占比例)对不同家庭背景儿童心理健康的影响机制.采用学校固定效应模型控制校际间差异后发现:(1)对于自尊和未来压力感知,班级结构存在对比效应,即班级内一般农村儿童比例越高,留守儿童的自尊水平越低,特殊结构家庭的儿童会感知到的未来压力更大,但对一般农村家庭儿童的影响不显著;(2)对于抑郁症状,班级结构则存在同化效应,即所在班级内其他学生的平均抑郁水平对个体自身的抑郁症状有显著的预测作用.     

TEACHER-VERSUS PEER-MEDIATED INSTRUCTION: AN ECOBEHAVIORAL ANALYSIS OF ACHIEVEMENT OUTCOMES

In three experiments, we compared the effects of instructional arrangements that varied in: (a) teacher versus peer mediators, (b) methods used, (c) levels of student academic responding generated, and (d) content taught and tested. Instructional arrangements (i.e., tasks, structure, teacher position, teacher behavior) and students' levels of academic responding were measured by an observation system which served as an index of the independent variables. Students' accuracy on weekly spelling, arithmetic, and vocabulary tests and pre- and post-standardized achievement tests (Experiments 2 and 3 only) were the dependent variables. Results indicated that the classwide peer tutoring, compared to the teacher's procedure, produced more student academic responding and higher weekly test scores, regardless of treatment order or subject matter content (Experiment 1). The four lowest performing students in each class, in particular, benefited from peer tutoring, often performing as well as the other students. These findings were replicated in Experiments 2 and 3 wherein content taught/tested was also manipulated. Standardized test score gains were higher in those areas in which peer tutoring was used longest. Issues related to the functional analysis of instruction and achievement gain are discussed.     

小学生社会情感能力、师生关系和同伴关系:一项交叉滞后研究

为探究小学生社会情感能力、师生关系和同伴关系之间的相互预测关系,使用社会情感能力量表、师生关系量表以及同伴提名的方式,对2776名四年级学生进行间隔两年的两次追踪调查。结果表明:(1)小学生的师生关系与社会情感能力呈双向预测关系;(2)小学生的同伴接纳与社会情感能力呈双向预测关系,小学生四年级时的同伴拒绝可负向预测六年级的社会情感能力;(3)小学生四年级时的同伴接纳与同伴拒绝可显著预测六年级的师生关系。研究揭示了小学生社会情感能力、同伴关系和师生关系之间复杂的预测关系,对促进小学生学校人际关系和社会情感能力的良好发展具有一定的启示作用。     

Proximal Peer-Level Effects of a Small-Group Selected Prevention on Aggression in Elementary School Children: An Investigation of the Peer Contagion Hypothesis

Examined peer contagion in small group, selected prevention programming over one school year. Participants were boys and girls in grades 3 (46 groups, 285 students) and 6 (36 groups, 219 students) attending school in low-resource, inner city communities or moderate resource urban communities. Three-level hierarchical linear modeling (observations within individuals within groups) indicated that individual change in aggression over time related to the average aggression of others in the intervention group. The individual child was pulled toward peers mean level of aggression; so the intervention appeared to reduce aggression for those high on aggression, and to make those low on aggression more aggressive. Effects appeared to be magnified in either direction when the child was more discrepant from his or her peers. From these results we derive a principle of discrepancy-proportional peer-influence for small group intervention, and discuss the implications of this for aggregating aggressive children in small group programs.     

Behavioral self-management in story writing with elementary school children

The effect of self-management procedures on objective writing responses and on the subjectively assessed quality of children's writing was investigated. All experimental procedures were applied to each of the 37 children in a regular Grade 3 class, and 14 of these children were randomly selected for data collection. Following baseline conditions, self-assessment plus self-recording of writing responses was introduced. This did not increase the number of sentences, number of different action words, or number of different describing words, or improve the quality of the stories. Self-determined and self-administered reinforcement was added to the self-assessment and self-recording procedures contingent on each of the writing responses in turn. Rates of responding were substantially increased and the stories received higher subjective ratings of quality from two independent judges. An increase in on-task behavior was correlated with self-reinforcement of writing responses.     

THE EFFICACY OF AN ALL-POSITIVE APPROACH TO CLASSROOM MANAGEMENT

This study addressed the question of whether an all-positive approach to classroom management can be effective. The on-task behavior and academic performance of eight, second- and third-grade children with behavior problems were examined. Results indicated that an all-positive approach that relied primarily on praise was not effective. However, when an individualized reward system was used, the children's rates of on-task behavior were high and stable. Similar effects were observed for academic productivity. Thus, a classroom can be managed using only positive consequences. However, to be successful, such an approach may require a considerable amount of teacher time and effort, particularly potent, varied and individual rewards, and high rates of appropriate behavior previously established using both positive and negative consequences.     

Comparability of peer-assessment measures: A multitrait-multimethod and selection analytic approach

This research attempted to assess the relationship among the Pupil Evaluation Inventory (PEI), sociometric nominations, and sociometric ratings in terms of (1) a multitrait-multimethod analysis, (2) selection agreement indices of extreme individuals, and (3) stability over an 8-week period. Subjects were members of four second-grade classrooms at a regional school serving a diverse population of children. While stability estimates for measures were adequate and evidence for convergent validity was reasonably good, evidence for divergent validity was weaker. Selection agreement analyses yielded highly variable results, indicating that different samples of children tend to be selected by different instruments despite the similarity in dimensions being tapped. Methodological and theoretical implications of these findings are discussed.This work was based on the first author's M.S. thesis under the direction of the second author.
