A growing body of research suggests that accounting for student specific variability in educational data can improve modeling accuracy and may have implications for individualizing instruction. The Additive Factors Model (AFM), a logistic regression model used to fit educational data and discover/refine skill models of learning, contains a…

Two experiments examined the influence of verb tense on how abstractly people construe action representations. Experiment 1 revealed that written descriptions of several daily events using the simple past tense (vs. simple present tense) resulted in actions and the action's target being seen as less likely and less familiar, respectively. In…

This dissertation studies the perception of tones in Thai, and aims to contribute to a formal characterization of speech perception more generally. Earlier work had argued that perception of tones involves retrieval of some abstract "autosegmental" representation provided by the phonology, while another line of work had argued for the…

This paper reports an action-research study on language learning strategies in tertiary education at a Colombian university. The study aimed at improving the English language performance and language learning strategies use of 33 first-year pre-service language teachers by combining elements from two models: the cognitive academic language…

In native speakers of gender-marking languages, mechanisms of gender production appear to be affected by the morphophonological cues to gender present in the noun phrase. This influence is manifested in higher levels of production accuracy when more transparent cues to gender are present in comparison to when they are not. The goal of the present…

The past two decades have shown an unexpected effectiveness of "Web-scale" data in natural language processing. Even the simplest models, when paired with unprecedented amounts of unstructured and unlabeled Web data, have been shown to outperform sophisticated ones. It has been argued that the effectiveness of Web-scale data has…

One core area of research in Second Language Acquisition is the identification and definition of developmental stages in different L2s. For L2 French, Bartning and Schlyter (2004) presented a model of six morphosyntactic stages of development in the shape of grammatical profiles. The model formed the basis for the computer program Direkt Profil…

The focus of this study was to assess the teaching effectiveness of English Grammar teachers in public Senior High Schools within the Cape Coast Metropolis using the Quality Teaching Model. It sought to ascertain how appropriately the three dimensions of the Quality Teaching Model are addressed in the teaching and assessment practices of the…

Numerous second language acquisition (SLA) researchers have tried to define grammatical difficulty in second and foreign language acquisition--often as part of an attempt to relate the efficacy of different types of instruction to the degree of difficulty of grammatical structures. The resulting proliferation of definitions and the lack of a…

Chinese EFL learners may have difficulty in speaking fluent and accurate English, for their speaking competence are likely to be influenced by cognitive, linguistic and affective factors. With the aim to enhance those learners' oral proficiency, this paper first discusses three effective models of teaching English speaking, and then proposes a…

This study investigated the effect of dynamic assessment on learners' syntactic knowledge. The main concern of this study was significant difference between dynamic and static assessment and the possible role of these two forms of assessment on the syntactic development of Iranian EFL college preparatory learners. To fulfill the purpose of the…

This study employed Bachman and Palmer's (2010) Assessment Use Argument framework to investigate to what extent the use of a second language oral test as an exit test in a Hong Kong university can be justified. It also aimed to help test developers of this oral test identify the most critical areas in the current test design that might need…

The communication pattern of Initiation/Response/Follow-Up (IRF) has long been an important instructional sequence in language classrooms. When language teachers combine IRF with the Response to Intervention (RTI) approach, they create a powerful model to evaluate student oral practice and self-assess effectiveness in creating language communities…

In this study, we use corpus analysis and computational modelling techniques to compare two recent accounts of the OI stage: Legate & Yang's (2007) Variational Learning Model and Freudenthal, Pine & Gobet's (2006) Model of Syntax Acquisition in Children. We first assess the extent to which each of these accounts can explain the level of OI errors…

This study investigated the validity of four theoretically motivated traits of writing ability across English and Korean, based on elementary school students' responses to letter- and story-writing tasks. Their responses were scored analytically and analyzed using confirmatory factor analysis. The findings include the following. A model of writing…
