Generative artificial intelligence (GenAI) has profoundly reshaped how graduate students conceptualise, design and conduct academic research in higher education. While current metrics predominantly focus on technology acceptance and usage patterns, they often neglect the diverse cognitive engagements in graduate students' integration of GenAI…

The study revisited the community of inquiry (CoI) instrument for construct revalidation. To that end, the study used confirmatory factor analysis (CFA) to examine four competing models (unidimensional, correlated-factor, second-order factor, and bifactor models) on model fit statistics computed using parameter estimates from a statistical…

The Online Student Connectedness Survey (OSCS) was introduced to the academic community in 2012 as an instrument designed to measure feelings of connectedness between students participating in online degree and certification programs. The purpose of this study was to examine data from the instrument for initial evidence of validity and reliability…

Establishing model parsimony is an important component of structural equation modeling (SEM). Unfortunately, little attention has been given to developing systematic procedures to accomplish this goal. To this end, the current study introduces an innovative application of the jackknife approach first presented in Rensvold and Cheung (1999). Unlike…

This study examined the construct validity of the TOEFL iBT Speaking subsection for the purposes of international teaching assistant (ITA) certification, a purpose for which it was not specifically designed. The factor structure of the new TOEFL was compared with that of another language performance test in use at a major American research…

The primary purpose of this study was to provide preliminary validity evidence for a 140-item form of the Vocabulary Size Test, which is designed to measure written receptive knowledge of the first 14,000 words of English. Nineteen native speakers of English and 178 native speakers of Japanese participated in the study. Analyses based on the Rasch…
