Accommodating Small Sample Sizes in Three-Level Models When the Third Level is Incidental.

Small samples sizes are a pervasive problem when modeling clustered data. In two-level models, this problem has been well studied, and several resources provide guidance for modeling such data. However, a recent review of small-sample clustered data methods has noted that no studies have investigated methods for modeling three-level data with small sample sizes. Furthermore, strategies for two-level models do not necessarily translate to the three-level context. Moreover, three-level models are prone to small samples because the "small sample" designation is primarily based on the sample size of the highest level, and large samples are increasingly difficult to amass as one progresses up a hierarchy. In this study, we focus on the case when the third level is incidental, meaning that the third level is important to consider but there are no explicit research questions at the third level. This study performs a simulation study to examine the performance of seven methods for modeling three-level data with a small sample at the third level. A motivating educational psychology example is also provided to demonstrate how the choice of method can greatly affect results.

Parental aspirations for their children's educational attainment: relations to ethnicity, parental education, children's academic performance, and parental perceptions of school climate.

This study examined parental aspirations for their children's educational attainment in relation to ethnicity (African American, Asian, Caucasian, Hispanic), parental education, children's academic performance, and parental perceptions of the quality and climate of their children's school with a sample of 13,577 middle and high school parents. All parents had relatively high educational aspirations for their children, and within each ethnic subgroup, parental education and children's academic performance were significantly and positively related to parental aspirations. However, moderating effects were found such that Caucasian parents with lower levels of education had significantly lower educational aspirations for their children than did parents of other ethnicities with similar low levels of education. Although the strength of the relationship between parental perceptions of school-related factors and parental aspirations for their children's educational attainment was not strong, it was most predictive of non-Caucasian parental aspirations for their children.

Friend influence on prosocial behavior: The role of motivational factors and friendship characteristics.

This study examined motivation (prosocial goals), individual characteristics (sex, ethnicity, and grade), and friendship characteristics (affective quality, interaction frequency, and friendship stability) in relation to middle adolescents' prosocial behavior over time. Ninth- and 10th-grade students (N = 208) attending a suburban, mid-Atlantic public high school and having at least 1 reciprocated friendship were followed for 1 year. Hierarchical regression analyses revealed that a friend's behavior is related to an individual's prosocial goal pursuit, which in turn, is related to an individual's prosocial behavior. Further, the affective quality of a friendship and the frequency with which friends interact moderate relations of a friend's prosocial behavior to an individual's prosocial goal pursuit.

Critical connections: health and academics.

BACKGROUND: While it is a national priority to support the health and education of students, these sectors must better align, integrate, and collaborate to achieve this priority. This article summarizes the literature on the connection between health and academic achievement using the Whole School, Whole Community, and Whole Child (WSCC) framework as a way to address health-related barriers to learning. METHODS: A literature review was conducted on the association between student health and academic achievement. RESULTS: Most of the evidence examined the association between student health behaviors and academic achievement, with physical activity having the most published studies and consistent findings. The evidence supports the need for school health services by demonstrating the association between chronic conditions and decreased achievement. Safe and positive school environments were associated with improved health behaviors and achievement. Engaging families and community members in schools also had a positive effect on students' health and achievement. CONCLUSIONS: Schools can improve the health and learning of students by supporting opportunities to learn about and practice healthy behaviors, providing school health services, creating safe and positive school environments, and engaging families and community. This evidence supports WSCC as a potential framework for achieving national educational and health goals.

Adolescent prosocial behavior: the role of self-processes and contextual cues.

Peer- and teacher-reported prosocial behavior of 339 6th-grade (11-12 years) and 8th-grade (13-14 years) students was examined in relation to prosocial goals, self-processes (reasons for behavior, empathy, perspective taking, depressive affect, perceived competence), and contextual cues (expectations of peers and teachers). Goal pursuit significantly predicted prosocial behavior, and goal pursuit provided a pathway by which reasons for behavior were related to behavior. Reasons reflected external, other-focused, self-focused, and internal justifications for behavior; each reason was related to a unique set of self-processes and contextual cues. Associations between prosocial outcomes and sex and race (Caucasian and African American) were mediated in part by self-processes and contextual cues. The implications of studying prosocial behavior from a motivational perspective are discussed.

Are effective teachers like good parents? Teaching styles and student adjustment in early adolescence.

This study examined the utility of parent socialization models for understanding teachers' influence on student adjustment in middle school. Teachers were assessed with respect to their modeling of motivation and to Baumrind's parenting dimensions of control, maturity demands, democratic communication, and nurturance. Student adjustment was defined in terms of their social and academic goals and interest in class, classroom behavior, and academic performance. Based on information from 452 sixth graders from two suburban middle schools, results of multiple regressions indicated that the five teaching dimensions explained significant amounts of variance in student motivation, social behavior, and achievement. High expectations (maturity demands) was a consistent positive predictor of students' goals and interests, and negative feedback (lack of nurturance) was the most consistent negative predictor of academic performance and social behavior. The role of motivation in mediating relations between teaching dimensions and social behavior and academic achievement also was examined; evidence for mediation was not found. Relations of teaching dimensions to student outcomes were the same for African American and European American students, and for boys and girls. The implications of parent socialization models for understanding effective teaching are discussed.
