School-average achievement is often reported to have positive effects on individual achievement (peer spillover effect). However, it is well established that school-average achievement has negative effects on academic self-concept (big-fish-little-pond effect [BFLPE]) and that academic self-concept and achievement are positively correlated and…

This article proposes a latent variable regression four-level hierarchical model (LVR-HM4) that uses a fully Bayesian approach. Using multisite multiple-cohort longitudinal data, for example, annual assessment scores over grades for students who are nested within cohorts within schools, the LVR-HM4 attempts to simultaneously model two types of…

Conventional multilevel modeling works well with purely hierarchical data; however, pure hierarchies rarely exist in real datasets. Applied researchers employ ad hoc procedures to create purely hierarchical data. For example, applied educational researchers either delete mobile participants' data from the analysis or identify the student only with…

Children experience good and bad days in their performance. Although this phenomenon is well-known to teachers, parents, and students it has not been investigated empirically. We examined whether children's working memory performance varies systematically from day to day and to which extent fluctuations at faster timescales (i.e., occasions,…

Self-determination theory and research suggest that students are more motivated and have higher achievement when teachers support their psychological needs for autonomy, competence, and relatedness. However, teachers might have difficulty supporting their students' psychological needs if their own psychological needs are not met, which might…

A positive school climate is characterized by a supportive, orderly, and fair interpersonal climate. Children's perceptions of interpersonal climate and school safety are associated with several academic and behavioral adjustment outcomes. The current study has two goals: (1) to better understand the contribution of school interpersonal climate to…

A growing body of research has shown that high quality early care and education (ECE) is positively related to the development of children's social and academic skills (e.g., Barnett, 2011; Lamb & Ahnert, 2006; NICHD ECCRN, 2006). There is evidence that high quality ECE experiences can improve children's levels of social adjustment (Bierman et…

This study examined the strength and direction of the relationship between 2009 NJ ASK 3 Language Arts and Mathematics scores and district social and demographic data (i.e., lone-parent household, level of parental education, and household income levels) found in the extant literature to influence student achievement on high-stakes standardized…
