This study compared the effectiveness of problem-based learning (PBL) versus lecture-based instruction (LBI) in high school foods and nutrition classes. Two classes were randomly assigned to the PBL group, while the remaining two were assigned to the LBI group. A pretest was administered. During the semester, LBI students received course content…

Associations between early child care and children's functioning though the end of third grade were examined. Some of the relations that had been detected before children's school entry were maintained. Higher-quality child care continued to be linked to higher scores in math, reading, and memory. More time spent in center care was associated with…

The present study examined factors that influence the process of learning to read in a second language. The Hebrew reading comprehension skills of 68 Russian-speaking children (mean age 7 years 6 months) were screened at the start of Grade 2. From this sample, 40 participants were selected: 20 successful learners and 20 unsuccessful learners.…

This article presents results from a 3-year longitudinal study of the growth patterns and correlates of perceived discrimination by adults and by peers among Black, Latino, and Asian American high school students. Results revealed a linear increase over time in levels of perceived discrimination by adults, whereas perceptions of discrimination by…

The present study examined relations among neighborhood structural and social characteristics, parenting practices, peer group affiliations, and delinquency among a group of serious adolescent offenders. The sample of 14-18-year-old boys (N = 488) was composed primarily of economically disadvantaged, ethnic-minority youth living in urban…

In this study, we defined and quantified the degree of cognitive conflict induced by a discrepant event from a cognitive perspective. Based on the scheme developed, we investigated the relationship between cognitive conflict and conceptual change, and the influences of students' cognitive characteristics on conflict in learning the concept of…

Individual differences in measures of prereading skills and in questionnaire measures of 4-5-year-old twins' print environments in Australia, Scandinavia, and the United States were explored with a behavioral-genetic design. Modest phenotypic correlations were found between environmental measures and the twins' print knowledge, general verbal…

The purpose of this study was to explore whether, in naturalistic physical education classes, the relation between teachers' early expectations and students' later perceived competence was moderated by the extent to which the motivational climate created by the teachers was autonomy supportive. Using a 1-year longitudinal design, data were…

Drawing from trauma-related theory (e.g., M. F. Schwartz & P. Gay, 1996), this article presents a model of associations among child sexual abuse (CSA), psychological distress, alexithymia, and disordered eating (DE). Structural equation modeling was used to test this conceptual model with a sample of female college students (N = 589). Results…

The self-report version of the Antisocial Process Screening Device (APSD) has become a popular measure for assessing psychopathic features in justice-involved adolescents. However, the internal consistency reliability of its component scales (Narcissism, Callous-Unemotional, and Impulsivity) has been questioned in several studies. This study…

Admissions data and first-year grade point average (GPA) data from 11 graduate management schools were analyzed to evaluate the predictive validity of Graduate Management Admission Test[R] (GMAT[R]) scores and the extent to which predictive validity held across sex and race/ethnicity. The results indicated GMAT verbal and quantitative scores had…

Establishing stability, defined as observing minimal measurement error in a test-retest assessment, is vital to validating psychometric tools. Correlational methods, such as Pearson product-moment, intraclass, and kappa are tests of association or consistency, whereas stability or reproducibility (regarded here as synonymous) assesses the…

We report on a study of the relationship between calculator technology and student learning in two introductory statistics class sections taught by the same instructor at the University of Texas at San Antonio. At the introduction of hypothesis testing and confidence intervals, one class section (A) was given graphing calculators capable of…

This study explored the relationships between emotional intelligence, locus of control, and self-efficacy among gifted and talented students participating in a two week long summer educational program.
