There is no need or point to testing of knowledge, attributes, traits, behaviours or abilities of an individual if information obtained from the test is inaccurate. However, by and large, it seems the estimation of psychometric properties of test items in classroomshas been completely ignored otherwise dying slowly in most testing environments. In…

International large-scale assessments provide cross-national data on students' cognitive and non-cognitive characteristics. A critical methodological issue that often arises in comparing data from cross-national studies is ensuring measurement invariance, indicating that the construct under investigation is the same across the compared groups.…

In recent years, some models for binary and graded format responses have been proposed to assess unipolar variables or "quasi-traits." These studies have mainly focused on clinical variables that have traditionally been treated as bipolar traits. In the present study, we have made a proposal for unipolar traits measured with continuous…

This study examines metacognitive monitoring in Turkish preschoolers aged 48--66 months, crucial for their learning and development. A specialised paired-association task was designed to assess higher-order thinking skills in this age group. Data from 160 children (52.5% girls, 47.5% boys; mean age 57.6 months, standard deviation 4.8) were…

In the present study, the Teacher Formative Assessment Literacy Scale (TFALS), developed by Yan and Pastore (2022a), was translated into Turkish to examine the factor structure and psychometric characteristics of the scale in a Turkish sample. Data was collected from 318 teachers, of whom 168 were males and 150 were females, working in different…

The current study sought out to advance the Social Self-Efficacy and Social Outcome Expectations scale using multiple approaches to scale development. Data from 583 undergraduate students were used in two scale development approaches: Classic Test Theory (CTT) and Item Response Theory (IRT). Confirmatory factor analysis suggested a 2-factor…

Over the past decade, the LLAMA language aptitude test battery has come to play an increasingly important role as an instrument in research on individual differences in language development. However, a potentially serious problem that has been pointed out by several scholars is that the LLAMA has not yet been carefully validated. We addressed this…

Weighted least squares (WLS), weighted least squares mean-and-variance-adjusted (WLSMV), unweighted least squares mean-and-variance-adjusted (ULSMV), maximum likelihood (ML), robust maximum likelihood (MLR) and Bayesian estimation methods were compared in mixed item response type data via Monte Carlo simulation. The percentage of polytomous items,…

Speech fluency has been extensively researched as a core construct for second language (L2) speaking assessment. Despite the broad consensus on its multifaceted nature, few researchers have empirically explored the dimensionality of this construct. Operationalizations of fluency vary across research and practice, using both holistic and…

The purpose of the current study was to examine the validity and diagnostic accuracy of the "Intervention Selection Profile--Social Skills" (ISP-SS), a brief social skills assessment tool intended for use with students in need of Tier 2 intervention. Participants included 160 elementary and middle school students who had been identified…

This study investigated the reliability and validity of Part 1 of the Informal Decoding Inventory (IDI), a free diagnostic assessment used to plan Tier 2 intervention for first graders with decoding deficits. Part 1 addresses single-syllable words and consists of five subtests that progress in difficulty and that contain real word and pseudoword…

Measures of teacher effectiveness have become a major research and policy issue due to the increased focus on teacher accountability during the past decade. Growing concerns about the variability in the quality of teaching and traditional approaches to measuring teacher effectiveness led to federal and state policies calling for more rigorous…

The study objectives were to develop, trial and evaluate a cross-cultural adaptation of the Adaptive Behavior Assessment System-Second Edition Teacher Form (ABAS-II TF) ages 5-21 for use with Indigenous Australian students ages 5-14. This study introduced a multiphase mixed-method design with semi-structured and informal interviews, school…

The purpose of this study was to examine the internal structure, relationships with other variables, and diagnostic accuracy of scores on the Autism Diagnostic Observation Schedule-Generic (ADOS-G; Lord et al., 1999) for the purpose of diagnostic decision-making. Participants were 462 children enrolled in a public school district in the southern…
