The purpose of this study was to determine if validity coefficients for ACT scores and high school grade point average (HSGPA) decayed or held stable over eight semesters of undergraduate study in science, technology, engineering, and mathematics (STEM) fields at civilian four-year institutions, and whether the decay patterns differed from those…

To identify ways that national culture, school characteristics, and individual attributes impact the victimization of students in Grade 8, data from the United States and three East Asian countries (i.e., Japan, S. Korea, and Taiwan) were compared using the 2011 Trends in International Mathematics and Science Study (TIMSS) and Hierarchical Liner…

Student performance is related to motivation to learn. As motivation generally declines during lower secondary education, one might expect performance to decline as well during this period. Though, until now, it has been unclear whether this pattern exists. In the present study, we examined student performance during the early years of secondary…

A large urban district (N = 90,546 students, n = 180 schools) implemented restorative interventions as a response to school discipline incidents. Findings from multilevel modeling of student discipline records (n = 9,921) revealed that youth from groups that tend to be overrepresented in suspensions and expulsions (e.g., Black, Latino, and Native…

Although a substantial amount of research has been conducted on differential item functioning in testing, studies have focused on detecting differential item functioning rather than on explaining how or why it may occur. Some recent work has explored sources of differential functioning using explanatory and multilevel item response models. This…

Multilevel modeling was used to examine contextual variations in the structure of the "self" in a sample of 918 lower- and upper-middle class early adolescents (M age = 10.37 years, SD = 1.19) from a "majority" cultural context (i.e., Barranquilla in the Caribbean region of Colombia) and a "nonmajority" context (i.e.,…

Student engagement is associated with many positive outcomes, including academic achievement, school persistence, and social-emotional well-being. The present study examined whether the Freedom Writers Institute, a professional development program designed to improve teachers' skills in creating personalized learning environments, can increase…

Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,364) and 2-level hierarchical linear models with site fixed effects, we examined between- and within-child associations between teacher-child relationship closeness and conflict and standardized measures of children's…

In the continuously changing society and knowledge-intensive economy, the demand for the recurrent updating of competencies is coming to the fore for all employees, including low-qualified employees. Employees are considered low qualified when they do not have a starter qualification for higher education. Although many educational studies have…

Chemistry self-efficacy has been defined as a student's beliefs about his or her own capability to perform a given chemistry task. These chemistry self-efficacy beliefs can be influenced by students' experiences in a course, and eventually, these beliefs could affect students' decisions to continue into STEM related-careers. In this study, we…

The aim of the current study was to examine mean-group differences on behavior rating scales and variables that may predict such differences. Sixty-five teachers completed the Clinical Assessment of Behavior-Teacher Form (CAB-T) for a sample of 982 students. Four outcome variables from the CAB-T were assessed. Hierarchical linear modeling was used…

Little is known about factors other than students' abilities and background variables that shape teachers' achievement expectations. This study was aimed at investigating the role of teachers' perceptions of students attributes (working habits, popularity, self-confidence, student--teacher relationships, and classroom behavior) in shaping…

We had 3 aims in the present study: (a) to examine the dimensionality of various evaluative approaches to scoring writing samples (e.g., quality, productivity, and curriculum-based measurement [CBM] writing scoring), (b) to investigate unique language and cognitive predictors of the identified dimensions, and (c) to examine gender gap in the…

Prior research has demonstrated that teachers' professional knowledge and motivation are strongly related to students' learning and motivation. Symptoms of teachers' stress and burnout (e.g., emotional exhaustion) are also thought to influence students' achievement, but no empirical study has tested this prediction. Using multilevel analyses and a…

The transition from adolescence to adulthood has been shown to be a time of amplified risk for individuals with autism spectrum disorders (ASD). It is unknown, however, whether problems in educational attainment and employment in the years after high school exit represent momentary perturbations in development or a turning point with long-lasting…
