Although Diagnostic Classification Models (DCMs) were introduced to education system decades ago, it seems that these models were not employed for the original aims upon which they had been designed. Using DCMs has been mostly common in analyzing large-scale non-diagnostic tests and these models have been rarely used in developing Cognitive…

This text comments on the Keynote article 'Microvariation in multilingual situations: The importance of property-by-property acquisition' by Marit Westergaard, who argues for Full Transfer Potential within the Linguistic Proximity Model in third language (L3) acquisition. The commentary points at some theoretical and methodological issues related…

The present study examined the performance of the bi-factor multidimensional item response theory (MIRT) model and higher-order (HO) cognitive diagnostic models (CDM) in providing diagnostic information and general ability estimation simultaneously in a listening test. The data used were 1,611 examinees' item-level responses to an in-house EFL…

This commentary discusses Westergaard's (2021) keynote article, which presents a comprehensive model of first language (L1), second language (L2), and third language (L3) acquisition. The commentary presents evidence from a previous study of L3 learners that provides support for Westergaard's property-by-property transfer proposal. The commentary…

Purpose: This study investigated the reading profiles of middle school Spanish-speaking emergent bilinguals (EBs) with significantly below grade level reading comprehension and whether these profiles varied in their reading comprehension performance over time. Method: Latent profile analyses were used to classify Grade 6 and 7 Hispanic EBs (n =…

The Simple View of Reading (SVR) model posits that reading is the product of word decoding and language comprehension and that oral language (listening) comprehension is the best predictor of reading comprehension once word-decoding skill has been established. The SVR model also proposes that there are good readers and three types of poor…

The purpose of the present study is to assess second language (L2) spoken English using automated scoring techniques. Automated scoring aims to classify a large set of learners' oral performance data into a small number of discrete oral proficiency levels. In automated scoring, objectively measurable features such as the frequencies of lexical and…

English language proficiency assessments (ELPA) are used in the United States to measure annually the English language progress and proficiency of English-language learners (ELLs), a subgroup of language minority students who receive language acquisition support mandated and largely funded by Title III (NCLB, 2001). ELPA proficient and…

In this article, I propose an index, called the Social Index of Educational Effectiveness (SIEE), which allows the establishment of an objective criterion to define the school's profile concerning the promotion of educational equity. It makes it possible to differentiate schools with an "inclusionary profile," (SIEE>0), from those…

The present study examines the production outcomes of late second language (L2) learners in order to determine if the mechanisms that allow the creation of phonetic categories remains available during the lifespan, as the Speech Language Model (SLM) claims. In addition, the study focuses on the type of interaction that exists between the first…

This article reports on the results of a research study that investigated Cantonese English as a second language (ESL) learners' perception of English speech sounds, their perceived relations between "similar" English and Cantonese sounds, as well as the applicability of the claims of the Speech Learning Model (SLM) to second language…

Previous research has shown that first language (L1) American English speakers discriminate the Spanish /[alveolar tap]/-/r/ and /[alveolar tap]/-/t/ contrasts significantly better than the /[alveolar tap]/-/d/ contrast, regardless of their proficiency level in Spanish (Rose, 2010a). Therefore, the current study follows the framework of the…

The purpose of this study was to investigate the use of English language proficiency and academic reading assessment scores to predict the future academic success of English learner (EL) students. Data from two cohorts of middle-school ELs were used to evaluate three prediction models. One cohort of students was used to develop the prediction…

This article investigates how measurement models and statistical procedures can be applied to estimate the accuracy of proficiency classification in language testing. The paper starts with a concise introduction of four measurement models: the classical test theory (CTT) model, the dichotomous item response theory (IRT) model, the testlet response…

Theoretical issues underlying the development of scales of language proficiency are examined. First, a brief classification of scale types is presented, and problems identified in them and advantages they offer are outlined. Discussion then moves to the issues of describing and measuring language proficiency. In this section, behaviorally-based…
