This research examined the important factors influencing the mathematics achievement of students in middle schools by hierarchically specifying the personal and contextual variables. The study focused on the effect of school climate at the class level and the effects of student gender, attitude toward mathematics, educational aspiration, parent…

More than 2,300 teachers in 241 schools across 25 states participating in a professional development approach to character education classroom management known as Development Designs 1 and Developmental Designs 2 (DD1 & DD2) were studied throughout the 2008-2009 academic school year. Data from this longitudinal program evaluation indicate that…

This article describes the theoretical and conceptual framework upon which the Developmental Designs (DD) approach is based and four fundamental human needs especially compelling for adolescents. These are used as the foreground to explain and contextualize the Developmental Designs' 10 classroom practices and professional development…

Commonality analysis is a method of partitioning variance to determine the predictive ability unique to each predictor (or predictor set) and common to two or more of the predictors (or predictor sets). The purposes of the present paper are to (a) explain commonality analysis in a multiple regression context as an alternative for middle grades…

Using data from the National Education Longitudinal Study of 1988 (NELS:88), path analytic procedures were performed to test a model of the effects of parent and peer encouragement to take algebra on the mathematics achievement of eighth grade students. The effects of socio-economic status (SES) on middle school algebra course-taking and…

The purpose of this study is to examine whether teachers' perceptions of educational value discontinuity are predictive of the psychological antecedents of academic performance (e.g., academic engagement and academic self-efficacy) during middle school. Educational value discontinuity is defined as the difference between teachers' actual…

Despite the success of many drug and alcohol prevention programs, drug and alcohol use by adolescents continues to be a problem. One important factor in preventing drug and alcohol use may be determining, in a non-intrusive manner, which students are most at risk for drug involvement. In the present study, the predictive relationship between…

Issues associated with drug and alcohol use as well as other delinquent behaviors among adolescents are of utmost importance to those concerned with student success in middle grades settings. In order to target preventive interventions for these problems, research suggests that educators should examine the risk and protective factors associated…

Associations between reading achievement and behavior, albeit problematic, are empirically supported in the literature. Although well documented, many of the studies were conducted outside of the school context using reading measures not typically aligned with school curricula. Furthermore, previous studies primarily document the existence of…
