The intent of this study was to explore the effects of two settings on self-concept and school satisfaction of academically advanced high school students. The research designs were causal-comparative and correlational. Participants were 224 partial-day academic Governor's School students and 56 academically advanced students in district schools in…

Verbal and quantitative reasoning tests provide valuable information about cognitive abilities that are important to academic success. Information about these abilities may be particularly valuable to teachers of students who are English-language learners (ELL), because leveraging reasoning skills to support comprehension is a critical aptitude…

Relationships between foreign language learning and four characteristics--anxiety, aptitude, attitudes and attributions for success--were investigated for 95 students enrolled in introductory level Spanish classes at a large, southeastern university in the United States. Examination grades resulted in significantly positive correlation with an…

The authors' purpose was to explore the effects of a supplementary, guided, silent reading intervention with 80 struggling third-grade readers who were retained at grade level as a result of poor performance on the reading portion of a criterion referenced state assessment. The students were distributed in 11 elementary schools in a large, urban…

Introduction: The study presented here explored the relationship between computer and Internet use and the performance on standardized tests by secondary school students with visual impairments. Methods: With data retrieved from the first three waves (2001-05) of the National Longitudinal Transition Study-2, the correlational study focused on…

Purpose: We contrast characteristics of respondents recruited using convenience strategies with those of respondents recruited by random digit dial (RDD) methods. We compare sample variances, means, and interrelationships among variables generated from the convenience and RDD samples. Design and Methods: Women aged 50 to 64 who work full time and…

This article contributes to the recent, but still limited, literature on the sociology of sibship. It argues that during childhood the ambivalent love/hate nature of sibship is played out through the sharing of knowledge, time and space. It draws on the work of Goffman to illustrate that children's sibling interactions tend to consist of…

This study proposes an approach for determining appropriate sample size for Welch's F test when unequal variances are expected. Given a certain maximum deviation in population means and using the quantile of F and t distributions, there is no need to specify a noncentrality parameter and it is easy to estimate the approximate sample size needed…

Child Trends has been asked by the Annie E. Casey Foundation to identify key opportunities that a new Administration might pursue to improve the capacity of the federal statistical system to monitor child and youth well-being. In this paper the authors discuss a number of areas of opportunity, offering concrete steps that can be taken, generally…

We apply the Supplemented EM algorithm (Meng & Rubin, 1991) to address a chronic problem with the "two-stage" fitting of covariance structure models in the presence of ignorable missing data: the lack of an asymptotically chi-square distributed goodness-of-fit statistic. We show that the Supplemented EM algorithm provides a…

Researchers in education are often interested in determining whether independent groups are equivalent on a specific outcome. Equivalence tests for 2 independent populations have been widely discussed, whereas testing for equivalence with more than 2 independent groups has received little attention. The authors discuss alternatives for testing the…

The effects of misspecifying intercept-covariate interactions in a 4 time-point latent growth model were the focus of this investigation. The investigation was motivated by school growth studies in which students' entry-level skills may affect their rate of growth. We studied the latent interaction of intercept and a covariate in predicting growth…

The purpose of this study is to investigate the effects of missing data techniques in longitudinal studies under diverse conditions. A Monte Carlo simulation examined the performance of 3 missing data methods in latent growth modeling: listwise deletion (LD), maximum likelihood estimation using the expectation and maximization algorithm with a…

This article describes SIMREL, a software program designed for the simulation of alpha coefficients and the estimation of its confidence intervals. SIMREL runs on two alternatives. In the first one, if SIMREL is run for a single data file, it performs descriptive statistics, principal components analysis, and variance analysis of the item scores…

It is widely known that there is a dearth of education research in South Africa which takes as its methodological basis experimentation. The emphasis has been on educators' and learners' experiential understanding in the first decade of democracy after apartheid, when qualitative research predominated. The article investigates, first, the extent…
