In this study, we test an information-processing model (IPM) of problem solving in science education, namely the working memory overload model, by applying catastrophe theory. Changes in students' achievement were modeled as discontinuities within a cusp catastrophe model, where working memory capacity was implemented as asymmetry and the degree…

Monitoring the Future (MTF) is designed to give sustained attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with and is conducted by a team of research professors at the University of Michigan's Institute for Social Research. Since its onset in 1975, MTF has been continuously…

The Sacramento City Unified School District (SCUSD), asked the Council of the Great City Schools to review the district's services for students with disabilities and provide recommendations to improve performance and narrow the achievement gap between these students and their nondisabled peers. This report was designed to help SCUSD achieve its…

Research on factors that may promote engagement is hampered by the absence of a measure of classroom-level engagement. Literature has suggested that engagement may have 3 dimensions--affective, behavioral, and cognitive. No existing engagement scales measure all 3 dimensions at the classroom level. The Classroom Engagement Inventory (CEI) was…

The transmission model of religious socialization was tested using a sample of American Jewish parents and adolescents. The authors expected that measures of religiousness among parents would be associated with those among their children. Interaction effects of denominational membership were also tested. Data were collected from a sample of 233…

Educators and policymakers have set a goal that all students graduate from high school ready for college and careers. A substantial body of research supports the idea that the path to college and career readiness begins well before middle and high school. In an earlier policy report, ACT examined the percentage of academically far off track…

The Florida College and Career Readiness Initiative is a statewide policy that mandates college placement testing of 11th-graders who meet high school graduation criteria but are unlikely to meet college readiness criteria. Students who score below college-ready on the Postsecondary Education Readiness Test (PERT) are required to take math and…

This report presents results of the National Assessment of Educational Progress (NAEP) 2010 civics assessment. National results for representative samples of students at grades 4, 8, and 12 are reported as average scale scores and as a percentage of students performing at or above three achievement levels: "Basic,"…

Long hours of paid employment during high school have been linked to a variety of problem behaviors, but questions remain about whether and to what extent work intensity makes any causal contribution. This study addresses those questions by focusing on how 12th-grade work intensity is associated with substance use and educational attainment in the…

Background: The objectives of this study were: (i) to compare the behavioural intentions of high school students towards individuals with intellectual disabilities and individuals with physical disabilities and (ii) to explore reasons for these behavioural intentions. Materials and methods: A sample of 319 Grade 9 and Grade 12 students in Ontario,…

We report longitudinal data in which we assessed the relationships between intelligence and support for two constructs that shape ideological frameworks, namely, right-wing authoritarianism (RWA) and social dominance orientation (SDO). Participants (N = 375) were assessed in Grade 7 and again in Grade 12. Verbal and numerical ability were assessed…

The role of hostile attributional style (HAS) in antisocial development has been well-documented. We analyzed longitudinal data on 585 youths (48% female; 19% ethnic minority) to test the hypothesis that response evaluation and decision (RED) mediates the relation between HAS and antisocial behavior in adolescence. In Grades 10 and 12, adolescent…

This paper deals with the design of interactivity in visualization tools. There are several factors that can be used to guide the analysis and design of the interactivity of these tools. One such factor is flow, which is concerned with the duration of interaction with visual representations of information--interaction being the actions performed…

This study investigated the impact of a range of variables as predictors of graduation potential for students with Specific Learning Disabilities (SLD) or Emotional Behavioral Disorders (EBD) within a large urban school district. These factors included the following characteristics and elements: (a) primary exceptionality, (b) gender, (c)…

Students in residential treatment center (RTC) schools are likely to have histories of extreme or ongoing relational trauma (e.g., abuse and neglect by primary caregivers), have substantial interpersonal and relationship problems, and exhibit many high-risk behaviors. Accordingly, these students may have particular difficulty forming positive…
