The Cross-Classified Mixed Effects Model (CCMEM) has been demonstrated to be a flexible framework for evaluating reliability by measurement specialists. Reliability can be estimated based on the variance components of the test scores. Built upon their accomplishment, this study extends the CCMEM to be used for evaluating validity evidence.…

The diversity in classrooms has increased worldwide. An equitable learning experience is the desired outcome. When planning instruction teachers must attend to the varied needs of their diverse students. The study presents a survey that assesses preservice teachers' use of different modalities of multiliteracies, new literacies, and literacy…

Experimental psychology is witnessing an increase in research on individual differences, which requires the development of new tasks that can reliably assess variations among participants. To do this, cognitive researchers need statistical methods that many researchers have not learned during their training. The lack of expertise can pose…

This study assessed the psychometric properties of the Italian version of the Preschool Anxiety Scale--Revised (PAS-R), a parent-reported measure of their preschool child's anxiety symptoms. The participants were mothers of 279 Italian preschoolers (age 2-7 years, M = 4.5 years). According to information criteria derived from a confirmatory factor…

Since the original and adapted versions of the scales that aim to measure foreign language enjoyment may not be appropriate for learners with low English proficiency levels, it seems necessary to develop scales in their native languages. This study aims to create a valid and reliable scale of foreign language learning enjoyment that can be applied…
