We make theoretical comparisons among five coefficients--Cronbach's [alpha], Revelle's [beta], McDonald's [omega][sub h], and two alternative conceptualizations of reliability. Though many end users and psychometricians alike may not distinguish among these five coefficients, we demonstrate formally their nonequivalence. Specifically, whereas…

A covariance structure modeling perspective on reliability estimation can be used to construct a formal approach to estimation of reliability in multilevel models. This article presents a didactic discussion of the relation between a structural modeling procedure for scale reliability estimation and the notion of reliability of observed means in…

An e-learner's characteristics are very important variables with regards to educational performance and the e-learning environment. This study suggests a research model, based on a successful e-learning model, which presents the relationship between e-learner's self-regulated learning strategies and the quality perception in LMS (learning…

With the rapidly changing demographics of the public school student population in the United States, teacher preparation programs have been driven to prepare teachers for linguistically and culturally diverse students. Considering these issues, the current research was conducted to benefit current teacher education research regarding English…

A 2 x 2 experiment was conducted in which instructor nonverbal immediacy and verbal immediacy were manipulated in a college classroom to examine causal links with cognitive and affective learning outcomes. Previous criticisms concerning immediacy and learning research were considered and multiple operationalizations of cognitive learning (i.e.,…

This article provides an overview of the challenges in implementing a game development course with limited resources in computing curricula. An approach to a holistic game development course is outlined in terms of its organization, software, and instructional methods. The course had 23 students enrolled in its first offering and was…

Breast cancer is the most common cancer among women in North Africa. Women in this region have unique reproductive profiles. It is essential to obtain reliable information on reproductive histories to help better understand the relationship between reductive health and breast cancer. We tested the reliability of a reproductive history-based…

This study examined the percentage of task-sampling variability in performance assessment via a meta-analysis. In total, 50 studies containing 130 independent data sets were analyzed. Overall results indicate that the percentage of variance for (a) differential difficulty of task was roughly 12% and (b) examinee's differential performance of the…

This paper reports on the development of a scale for determining the quality of the student e-learning experience at the degree level when the student learning context is predominately a campus-based experience. Rapid developments in the use of information and communication technologies (ICT) in higher education require methods for evaluating the…

In this paper we review different methods for teachers to recommend accommodations in large scale tests. Then we present data on the stability of their judgments on variables relevant to this decision-making process. The outcomes from the judgments support the need for a more explicit model. Four general categories are presented: student…

Care managers, including nurses and social workers, often lack information that would help them more effectively target services to caregivers' needs. Useful information includes the type of services that will be most helpful for caregivers and the best time to start using these services. Generally, caregivers are simply told what services they…

Due to the relative inability of individuals with intellectual disabilities (ID) to provide an accurate and reliable self-report, assessment in this population is more difficult than with individuals in the general population. As such, assessment procedures must be adjusted to compensate for the relative lack of information that the individual can…

Career and Technical Education (CTE) is a nationwide program that emphasizes training for primary, secondary, and post secondary educational stages for the career and workforce needs of today and tomorrow's society. Mandated indicators of success have been set in place and secondary schools are expected to improve student's skill levels in…

In the field of educational psychology, there is diverse and active research in motivation for learning and achievement. Many instruments exist for assessing students' motivation, primarily as self-report. Fewer instruments are available for assessing "teachers'" perceptions of their students' motivation, and fewer still for assessing teachers'…

The authors present the development and the validation of the four-dimensional, twenty-five-item, five-point Kindergarten Environment Rating Scale (KERS). The Cohen's Kappa of the items indicates acceptable reliability for the instrument. The content validity and confirmatory factor analysis indicates that the data obtained using the KERS could…
