Background: Previous research has indicated positive effects of early developmental intervention (EDI) on the development of children in developing countries. Few studies, however, have examined longitudinally when differential treatment effects may be observed and whether differential outcomes are associated with exposure to different risk…

The primary focus of this study was to examine the attitudes of the secondary mathematics teachers toward the inclusion of students with learning disabilities in the general mathematics classroom. Specifically, this study was concerned with the influence of selected demographic variables and school variables on the attitudes of secondary…

In this dissertation, I aim to clarify the factors affecting a consumers' choice between the Internet and a financial planner for making saving and investment decisions, based on household production theory. Moreover, I explore the likelihood of an individual being an Internet user (vs. a non-user), a financial planner user (vs. a non-user),…

This study assessed whether and how self-explanation reading training, provided by iSTART (Interactive Strategy Training for Active Reading and Thinking), improves the effectiveness of comprehension processes. iSTART teaches students how to self-explain and which strategies will most effectively aid comprehension from moment-to-moment. We used…

The purpose of this study is to provide empirical benchmarks of the conditional reliabilities of state tests for samples of the student population defined by ability level. Given that many educational interventions are targeted for samples of low performing students, schools, or districts, the primary goal of this research is to determine how…

The effect of feedback and materials on perceptual learning was examined in listeners with normal hearing who were exposed to cochlear implant simulations. Generalization was most robust when feedback paired the spectrally degraded sentences with their written transcriptions, promoting mapping between the degraded signal and its acoustic-phonetic…

The author investigated the impact of assessment methods on student performance on accounting tests. Specifically, the author used analysis of variance to determine whether the use of computer-based tests instead of paper-based tests affects students' traditional test scores in accounting examinations. The author included 2 independent variables,…

To characterise statistical inference in the workplace this paper compares a prototypical type of statistical inference at work, statistical process control (SPC), with a type of statistical inference that is better known in educational settings, hypothesis testing. Although there are some similarities between the reasoning structure involved in…

Distance learning (DL) is a popular option in higher education. Information technology (IT) has made education more available for students without regard to location or time. Universities are now offering online degrees at all levels. This study presents an empirical investigation designed to identify some advantages and disadvantages of distance…

The construct of anxiety has been captivating the interest of SLA [second-language acquisition] researchers for a long time. Numerous observations show that most individuals experience anxiety when learning a foreign language (FL) and using it, both in classroom and real-life contexts, though to a different extent. An analysis of studies conducted…

The authors investigated the extent to which taking specific types of Advanced Placement (AP) courses and the number of courses taken predicts the likelihood of passing subject benchmarks and earning a score of 19 on the composite score on the ACT test, and examined the role gender plays in the projection. They found evidence that taking an AP…

The objective of this study was to provide empirical evidence to support psychometric properties of a modified four-dimensional model of the Leadership Scale for Sports (LSS). The study tested invariance of all parameters (i.e., factor loadings, error variances, and factor variances-covariances) in the four-dimensional measurement model between…

This article presents procedures and results from a 2-year project developing science key vocabulary (KV) short tests suitable for progress monitoring Grade 5 science in Texas public schools using computer-generated, -administered, and -scored assessments. KV items included KV definitions and important usages in a multiple-choice cloze format. A…

In experimental designs with nested structures, entire groups (such as schools) are often assigned to treatment conditions. Key aspects of the design in these cluster-randomized experiments involve knowledge of the intraclass correlation structure, the effect size, and the sample sizes necessary to achieve adequate power to detect the treatment…

This study considers the problem of testing the difference between treatment and control groups on m [greater than or equal to] 2 measures when it is assumed a priori that the treatment group will perform better than the control group on all measures. Two procedures are investigated that do not rest on the assumptions of covariance homogeneity or…
