Direct linkDavenport, Becky R.; Hegland, Susan; Melby, Janet N. – Early Child Development and Care, 2008
A stratified sample of 34 three-year-old to five-year-old boys and their parents (30 mothers) was observed in their homes during free-play and problem-solving interactions. Observer-ratings of behaviors of parents in each interaction were examined in relation to teachers' ratings of the boys' problem behaviors in a childcare setting. Parent…

Wang, Shudong; Jiao, Hong; Young, Michael J.; Brooks, Thomas; Olson, John – Educational and Psychological Measurement, 2008
In recent years, computer-based testing (CBT) has grown in popularity, is increasingly being implemented across the United States, and will likely become the primary mode for delivering tests in the future. Although CBT offers many advantages over traditional paper-and-pencil testing, assessment experts, researchers, practitioners, and users have…

Ranalli, Jim – Computer Assisted Language Learning, 2008
With their realistic animation, complex scenarios and impressive interactivity, computer simulation games might be able to provide context-rich, cognitively engaging virtual environments for language learning. However, simulation games designed for L2 learners are in short supply. As an alternative, could games designed for the mass-market be…

Results after two years of using three reading comprehension curricula show gains from one program and no effects for the other two on reading comprehension for fifth-graders, according to a study released by the National Center for Education Evaluation and Regional Assistance in the Institute of Education Sciences. The study focused on whether…

Saltiel, Henry – ProQuest LLC, 2011
A quasi-experiment using quantitative methods was conducted to examine the effects on academic student outcomes when a cohort of employed low-SES community college commuter students (the treatment group, N=198) participated in a comprehensive support and access intervention program, compared with similar students (the matched comparison group,…

Grigg, W.; Donahue, P.; Dion, G. – National Center for Education Statistics, 2007
This report presents results of the 2005 National Assessment of Educational Progress (NAEP) in reading and mathematics at grade 12. Assessment results based on a nationally representative sample of twelfth-graders assessed in each subject are reported as average scores and as the percentages of students performing at or above three achievement…

Esbensen, A. J.; Benson, B. A. – Journal of Intellectual Disability Research, 2007
Background: The theories supporting cognitive treatment for depression among individuals with intellectual disability (ID) have not been formally tested with this population. The current study evaluated Becks cognitive theory of depression to determine its appropriateness for adults with ID. Methods: Forty-eight adults with primarily mild or…

Lewis, Charla P. – 1999
The sampling distribution is a common source of misuse and misunderstanding in the study of statistics. The sampling distribution, underlying distribution, and the Central Limit Theorem are all interconnected in defining and explaining the proper use of the sampling distribution of various statistics. The sampling distribution of a statistic is…

Examines the question of how large a sample must be in order to produce empirical Bayes estimates which are preferable to other commonly used estimates, such as proportion correct observed score. (Author/RC)

Peer reviewedOverall, John E.; Woodward J. Arthur – Psychometrika, 1974
A procedure for testing heterogeneity of variance is developed which generalizes readily to complex, multi-factor experimental designs. Monte Carlo studies indicate that the Z-variance test statistic presented here yields results equivalent to other familiar tests for heterogeneity of variance in simple one-way designs where comparisons are…

Taylor, Dianne L. – 1991
As significance testing comes under increasing criticism, some researchers are turning to other indices to evaluate their findings. Included among the alternative options are the interpretation of effect size estimates and the evaluation of sample specificity (invariance testing). Using a hypothetical data set of 64 cases and two predictor…

Koffler, Stephen L. – 1982
Too often researchers rely upon the classical normal theory parametric tests to analyze non-normal data, even though the tests may not be robust to violations of that assumption. Fligner's class of two-sample tests for scale is an important development because the test is distribution-free and has desirable properties. This paper outlines the…
