Within the United States, there are a variety of early education models and curricula aimed at promoting young children's pre-academic, social, and behavioral skills. This study, using data from the Miami School Readiness Project (Winsler et al., 2008, 2012), examined the school readiness gains of low-income Latino (n = 7,045) and Black (n =…

Using German data, we examined the effects of one specific type of acceleration--grade skipping--on academic performance. Prior research on the effects of acceleration has suffered from methodological restrictions, especially due to a lack of appropriate comparison groups and a priori measurements. For this reason, propensity score matching was…

This cross-sectional study examines the importance of English phonological and orthographic processing skills to English word reading and spelling in 3 groups of younger (8-9 years) and older (11-12 years) children from different language backgrounds: English monolingual, English first language (L1)-Mandarin second language (L2), and Mandarin…

The primary aim of this group randomized trial was to test the efficacy of INSIGHTS Into Children's Temperament (INSIGHTS) in increasing the academic achievement and sustained attention and reducing the disruptive behavior problems of low-income kindergarten and 1st grade children. Twenty-two urban elementary schools serving low-income…

We compared 5 different statistics (i.e., G index, gamma, "d'", sensitivity, specificity) used in the social sciences and medical diagnosis literatures to assess calibration accuracy in order to examine the relationship among them and to explore whether one statistic provided a best fitting general measure of accuracy. College…

Intelligent Tutoring Systems (ITS) are computer programs that model learners' psychological states to provide individualized instruction. They have been developed for diverse subject areas (e.g., algebra, medicine, law, reading) to help learners acquire domain-specific, cognitive and metacognitive knowledge. A meta-analysis was conducted on…

The focus of this study was connections among 3 aspects of mathematical cognition at 2nd grade: calculations, word problems, and prealgebraic knowledge. We extended the literature, which is dominated by correlational work, by examining whether intervention conducted on calculations or word problems contributes to improved performance in the other…

Background and Aim: Spaced restudy has been typically tested with written learning materials, but restudy with visual representations in actual classrooms is under-researched. We compared the effects of two spaced restudy interventions: A Diagram-Based Restudy (DBR) warm-up condition and a business-as-usual Text-Based Restudy (TBR) warm-up…

Background: Strategy-focused writing instruction trains students both to set explicit product goals and to adopt specific procedural strategies, particularly for planning text. A number of studies have demonstrated that strategy-focused writing instruction is effective in developing writing performance. Aim: This study aimed to determine whether…

Some U.S. school districts are experimenting with single-sex schooling, hoping that it will yield better academic outcomes for students. Empirical research on the effects of single-sex schooling, however, has been equivocal, with various studies finding benefits, disadvantages, or no effect. Most of this research is marred because families…

For the international Trends in International Mathematics and Science Study (TIMSS2007) math and science motivation scales (self-concept, positive affect, and value), we evaluated the psychometric properties (factor structure, method effects, gender differences, and convergent and discriminant validity) in 4 Arab-speaking countries (Saudi Arabia,…

This study examined the measurement and interpretation of self-concept among the growing population of children who are English Language Learners (ELLs). More specifically, a 3-group analysis was conducted comparing native English-speaking children, Spanish-speaking ELLs, and ELLs from Asian language backgrounds. Data were drawn from the Early…

The purpose of this study was to investigate the effects of 1st-grade number knowledge tutoring with contrasting forms of practice. Tutoring occurred 3 times per week for 16 weeks. In each 30-min session, the major emphasis (25 min) was number knowledge; the other 5 min provided practice in 1 of 2 forms. Nonspeeded practice reinforced relations…

The use of grades to motivate constitutes an unresolved theoretical controversy. In 2 experiments carried out with different age groups and academic tracks, a standard-grade condition was compared with a condition in which differential scoring engendered higher grades and with a no-grade condition. The relative power of task performance and task…

The present study compared the effectiveness of 2 approaches to remedy the inaccuracy of self-monitoring of reading comprehension. The first approach attempts to enhance self-monitoring by strengthening the cues utilized in monitoring. The second approach replaces self-monitoring with external regulation based on objective evaluative information.…
