Decades of research on engagement, retention, and under-representation in STEM conclude that a better understanding of learner development as a long-term, social process is needed. Social identity theory is increasingly used to understand the interplay between individual development and social structure. The present report summarises findings from…

This research explores the interplay between students' understandings of proportional and functional relationships. Approximately 90 students participated in an early algebra intervention in Grades 3- 5. Before the intervention and after each year of the intervention, we evaluated their understandings of proportional and functional relationships.…

This study examined the longitudinal effects of a middle school reform mathematics curriculum on students' open-ended problem solving in high school. Using assessment data from a large, longitudinal project, we compared the open-ended problem-solving performance and strategy use of high school students who had used the Connected Mathematics…

This paper reports on longitudinal study regarding integrity of testing in an online format as used by e-learning platforms. Specifically, this study explains whether online testing, which implies an open book format is compromising integrity of assessment by encouraging cheating among students. Statistical experiment designed for this study…

This paper explores how curriculum and classroom conceptual and procedural emphases affect the learning of algebra for students of color. Using data from a longitudinal study of the Connected Mathematics Program (CMP), we apply cross-sectional HLM to lend explanatory power to the longitudinal analysis afforded by Growth Curve Modeling that we have…

This paper reports data from the evaluation of the numeracy component of a long-running educational intervention, covering the period from 2001 to 2008. "QuickSmart" is both an intervention and research project operating in Australian schools. It is a structured intervention program designed for middle-school students (ages 10 to 13…

This study seeks to extend the literature on higher education enrollment patterns during times of recession by examining patterns of enrollment and successful course completion in one of the world's largest higher education systems--the California Community College system. The data are drawn from publicly available data sources on the web. CCC…

This paper describes the operations of a community-based, racially-mixed, day-long, day care center, its social environment and the staff's response to one very young, disruptive black boy. Data for the study were collected over a 3-year period of participant observation among approximately 25 children ranging in age from 2 through 5 from low…

Parental conflict as it occurs in the context of divorce was studied in an effort to determine the role that conflict plays in a variety of psychosocial problems in children. Data were drawn from a 5-year longitudinal study of about 1,000 families who filed for divorce in 1984. The first phase of the study involved a series of interviews with the…

This investigation used data from the 28-year-old New York Longitudinal Study to examine the relationship between various negative emotional and behavioral characteristics (e.g., aggression, anxiety, undercompliance, depressive mood) and adjustment. A total of 133 white, middle-class children were rated on these negative characteristics from…

In the study, a part of longitudinal research focused on the emergence of mathematical knowledge structures in a learner's mind is presented. It concentrates on the analysis of introspective data gained from the author's study of a non-standard arithmetic structure in terms of the model of abstraction in context (Hershkowitz, Schwarz and Dreyfus).…

Children in a longitudinal high-risk infant follow-up program were evaluated at age 5 to determine whether they demonstrated behavior problems or cognitive deficits exceeding expectations based on conditions in their home environments. Normal expectations were determined through regression analyses on a group of age-matched controls. All high-risk…

Extensive education research on the contribution of teachers to student achievement produces two generally accepted results. First, teacher quality varies substantially as measured by the value added to student achievement or future academic attainment or earnings. Second, variables often used to determine entry into the profession and…

Economic loss and hardship during the 1929 Depression produced marital tension resulting from increased conflict over finances and temperamental behavior of husbands and wives. Data on 110 couples were obtained from the Berkeley Study at the Institute of Human Development in California. Annual data were collected from wife, home observer, and…

This longitudinal study identified hard-to-manage older toddlers and younger preschoolers, assessed the developmental course and prognostic significance of their difficult behavior, and delineated family factors possibly associated with early and persistent problems. Obtained from parents, teachers, and observers, cross-situational and…
