This study explores college professor perceptions of effective professor Characteristics through the lens of Media Naturalness Theory (MNT). A survey questionnaire was administered to samples of college professors in two countries (USA and Qatar) regarding their perceptions of effective professor's characteristics. Demographic variables such as…

Just as we can't expect actors trained primarily for the stage to perform the same way in films, conventional Public Speaking (PS) must adapted to digital environments. This shift emphasizes the need to treat Digital Oratory (DO) as a separate, skill-based discipline. Our research aims to examine DO instruction in English as a Foreign Language…

Mixture Rasch (MixRasch) models conventionally assume normal distributions for latent ability. Previous research has shown that the assumption of normality is often unmet in educational and psychological measurement. When normality is assumed, asymmetry in the actual latent ability distribution has been shown to result in extraction of spurious…

The present quantitative study explored pre-service teachers' perspectives regarding the quality of their Teacher Education Programme (TEP) in Lebanon, Qatar, and China. The sample consisted of 326 pre-service school teachers who completed a survey designed to examine their perception of the following indicators of TEP quality: (1) a shared vision…

This study explores whether collaboratively writing about local issues would enable learners to deepen their understanding of their relationship with their own social context. A discursive space within an English for Academic Purposes (EAP) course at an institution of higher education in Qatar was created. This was accomplished by replacing the…

Purpose: The purpose of this paper is to examine the role of neoliberalism and the accreditation of educational leadership programs in one Gulf Cooperation Council (GCC) country by contextualizing the accreditation process and closely examining the Educational Leadership Constituent Council (ELCC) standards used by NCATE, now CAEP, to accredit…

In this study, we contrast results from two differential item functioning (DIF) approaches (manifest and latent class) by the number of items and sources of items identified as DIF using data from an international reading assessment. The latter approach yielded three latent classes, presenting evidence of heterogeneity in examinee response…

The purpose of this study was to explore what may be contributing to differences in performance in mathematics on the Trends in International Mathematics and Science Study 2007. This was done by using a mixture item response theory modeling approach to first detect latent classes in the data and then to examine differences in performance on items…

In this study, we investigated differential item functioning (DIF) and its sources using a latent class (LC) modeling approach. Potential sources of LC DIF related to instruction and teacher-related variables were investigated using substantive and three statistical approaches: descriptive discriminant function, multinomial logistic regression,…

Alternatives to vertical scales are compared for measuring longitudinal academic growth and for producing school-level growth measures. The alternatives examined were empirical cross-grade regression, ordinary least squares and logistic regression, and multilevel models. The student data used for the comparisons were Arabic Grades 4 to 10 in…
