The United States faces high demand for science, technology, engineering, or mathematics (STEM) professionals and a scarce supply of individuals who pursue STEM careers, especially minority populations in the U.S with proficiency in a language other than English. The primary goal of this research was to determine the impact of use of Spanish in…

Purpose: The purpose of this paper is to conceptualize error reporting as a strategy for informal workplace learning and investigate nurses' error reporting cost/benefit evaluations and associated behaviors. Design/methodology/approach: A longitudinal survey study was carried out in a hospital setting with two measurements (time 1 [t1]:…

Researchers, institutional leaders, government policy makers, and leading foundations note the significant role an educated Latina/o population plays in the nation, future workforce, and democracy. This longitudinal study examines the experiences in U.S. colleges and universities that prepare Latina/o students for participation in American…

The present study investigated the development of fraction comparison strategies through a longitudinal analysis of children's responses to a fraction comparison task in 4th through 6th grades (N = 394). Participants were asked to choose the larger value for 24 fraction pairs blocked by fraction type. Latent class analysis of performance over item…

Objective: The purpose of this study was to determine the reliability of longitudinally reporting age at first drink (AFD), and to test AFD and setting of first drink (SFD) as predictors of collegiate problem drinking. Participants: 338 first-year college students were interviewed multiple times during their first academic year, from May 2011…

The present study used nationally representative data from the U.S. Panel Study of Income Dynamics (PSID) merged with census-track data from the American Community Survey (ACS) to model race-ethnic disparities in overweight, obesity, and obesity-related disease among children and adolescents as a function of neighborhood race-ethnic segregation,…

This longitudinal study investigated the effects of a mastery motivational climate in physical education (PE) classes on 2×2 achievement goal orientation and dominance, self-regulated learning (SRL), and physical activity (PA) in leisure time. A total of 408 (264 women, 144 men) university students were randomly assigned to two groups:…

Although many studies have documented developmental change in mathematics motivation, little is known about how these trends predict math performance. A sample of 288 participants from the United States reported their perceived math ability, math utility value and math interest in 5th, 7th and 9th grades. Latent growth curve models estimated…

This study examined the impact of childhood reading disability (RD) on adult educational attainment and income. Participants' (N = 1,344) RD was assessed at age 7, and adult educational attainment and income were assessed in midlife using categorical variables. Participants with RD at age 7 were 74% (95% CI: 0.18, 0.37) less likely to attain a…

Background: Evidence exists that there are two main underlying cognitive factors in mathematical difficulties: working memory and number sense. It is suggested that real math difficulties appear when both working memory and number sense are weak, here referred to as the double deficit (DD) hypothesis. Aims: The aim of this study was to test the DD…
