This study examines the power of cognitive and noncognitive variables to predict students' performance in algebra. We investigated students' prior year's assessment scores and demographic characteristics to predict eighth-grade algebra scores. Using California statewide assessment data, we explored predictive factors in three regression models.…

This study investigates how much the geographic shapes of school attendance zones contributes to their levels of income segregation while holding constant levels of income segregation across residential areas. Income segregation across attendance zones is measured with the rank ordered information theory index. Income segregation across…

This study examined the influence of enrollment in a Montessori adolescent program on the development of self-determination. The study focused on seventh-grade students. Student feelings of self-determination were recorded through three cycles of interviews throughout the year to capture the change, if any, in feelings of self-determination.…

Purpose: The purpose of this quantitative, experimental study was to determine if there was a significant difference in 2016 Smarter Balanced Assessment (SBA) English language arts (ELA) writing levels and ELA overall achievement levels between 7th- and 8th-grade students with and without access to Chromebooks for at least one 46-minute period of…

School belonging (i.e., social connectedness to school) has positive implications for academic achievement and well-being. However, few studies have examined the developmental antecedents of school belonging, particularly for students of Mexican origin. To address this gap in the research literature, the present study examined reciprocal relations…

Despite post-racial rhetoric, stereotypes remain salient for American youth. We surveyed 150 elementary and middle schoolers in Northern California and conducted case studies of 12 students. Findings showed that (a) students hold school-related stereotypes that get stronger in middle school, (b) African American and Latino students experience…

We investigated general vocabulary and academic vocabulary growth trajectories of adolescent language minority students using an individual growth modeling approach. Our analytical sample included 3161 sixth- to eighth-grade students from an urban school district in California. The language minority students in our sample were classified as…

Purpose: Adult relationships provide critical support for adolescents because of their potential to foster positive development and provide protective influences. Few studies examine multiple ecological layers of adult relationships in connection with well-being and depression. This study examines the influence of relationships from multiple…

New analytical tools have facilitated the exploration of the trajectories of alcohol use; however, there are a limited number of studies that explore early adolescence. A sample of 5,903 youths followed from sixth through eighth grade was used to (1) examine the trajectories of alcohol use and (2) determine the degree to which common correlates…

Reducing risky sexual behaviors and their negative health outcomes in youth remains a priority for health educators. Years of research have documented media's effect on various adolescent health risks, including sexual behaviors. As technology evolves and youth access to media increases, understanding the role of media in adolescent health risk…

Although researchers call for inquiry learning in science, science assessments rarely capture the impact of inquiry instruction. This paper reports on the development and validation of assessments designed to measure middle-school students' progress in gaining integrated understanding of energy while studying an inquiry-oriented curriculum. The…

The purpose of this study was to determine whether age differences affect students' academic achievement, and whether age differences affect students in low-income areas differently than those in mixed or higher-income areas. Student achievement data for grades 3, 7, and 11 in language arts and math were obtained from a variety of schools located…

Exergames (active video games that require kinesthetic movement) played in proximity to other players or against a gaming machine have been linked to positive increases in cognitive functioning. This study tested to see if remote exergame play over the Internet had an impact similar to exergames that are played in proximity. The study shows that…

Graphs are often conjoined with text passages in history textbooks to help students comprehend complex constructs. Four linkages connect text and graphs: appropriate elements, fitting patterns, suitable labels and causal markers. Graphs in current textbooks contain few such linkages and seldom mirror the construct under study. An experiment…

This paper reports the results of a descriptive study on the use of a technology-enhanced formative assessment system called Accelerated Math (AM) for ELLs and their native-English-speaking (NES) peers. It was comprised of analyses of an extant database of 18,549 students, including 2,057 ELLs, from grades 1 through 8 across 30 U.S. states. These…
