Item response theory (IRT) encompasses a broader class of measurement models than is commonly appreciated by practitioners in educational measurement. For measures of vocabulary and its development, we show how psychological theory might in certain instances support unipolar IRT modeling as a superior alternative to the more traditional bipolar…

Second language acquisition researchers often face particular challenges when attempting to generalize study findings to the wider learner population. For example, language learners constitute a heterogeneous group, and it is not always clear how a study's findings may generalize to other individuals who may differ in terms of language background…

While language aptitude and motivation are considered to be important contributors to second language (L2) attainment, two major gaps in the past research have been (1) a lack of nonlinear models stemming from a naive and tacit assumption that learning outcomes are linearly related to their predictors, and (2) a lack of unified and integrative…

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…

This study investigates lexical transfer in four German learners' oral production of L3 Swedish. They have already learned English as an L2. The point of departure is Williams and Hammarberg's [1998. Language switches in L3 production: implications for a polyglot speaking model. "Applied Linguistics," 19, 295-333] case study in which…

Aim/Purpose: The research investigates the impact of Information and Communication Technologies (ICT) on Iranian refugees' settlement in Australia. Background: The study identifies the issues of settlement, such as language, cultural and social differences. Methodology: The Multi-Sited Ethnography (MSE), which is a qualitative methodology, has…

This paper is a report on the findings of research and development into the instructional model 'enhancing Thai Generation Z' creative thinking with Scratch through the spiral mode. The purposes of this study are: 1) to develop; 2) to evaluate and gain experts' opinion on the proposed model, adapted from a creative thinking spiral first used in…

Currently, a growing number of teaching approaches focus on aspects of variation in language (e.g. English as a Lingua Franca (ELF), World Englishes, English for Specific Purposes (ESP), genre theories, etc.); however, each of these approaches tends to focus on particular (specific) aspects of language variation and do not fully account for the…

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…

The number of heritage language learners in American universities is increasing each year. Similar to monolingual students, this subgroup of learners is required to complete university level "foreign language" coursework, which can be a source of anxiety. Particularly, this subgroup of learners may experience high levels of anxiety due…

This study examines the post-graduation plans of international science and engineering doctoral students at a public research-intensive university, and the extent to which graduate school experiences influence post-graduation plans. The study is grounded in Tinto's Integration Model as well as Berry's Acculturation Model. Study findings highlight…

Speech acts are the major concern of interlanguage pragmatists. The present study aimed to 1) examine the reliability and validity of an interlanguage pragmatic (ILP) competence test on speech acts in a Chinese EFL context, and 2) investigate EFL learners' variations of ILP competence by language proficiency. Altogether 390 students participated…

Although fluency constitutes an essential component of second language (L2) proficiency, there are mixed results and gaps in the literature on how L2 speakers' fluency differs from fluent speech production in a first language (L1). The research reported in this article investigated utterance fluency and cognitive fluency of L1 English…

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 main goal of this paper is to analyze how the age factor behaves as an alleged individual difference (ID) variable in SLA by focusing on the influence that the learning context exerts on the dynamics of age of onset (AO). The results of several long-term classroom studies on age effects will be presented, in which I have empirically analyzed…
