This study investigates how aspects of collocational proficiency affect the ratings that expert examiners give to second language (L2) English learner essays. Lexical proficiency is a multi-faceted phenomenon and certain aspects of it are particularly impactful on human judgements, including lexical sophistication and accuracy. However, the…

The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

Second language (L2) writing has been determined to be influenced by what is read, with language learners tending to borrow words and short phrases from input texts while writing (e.g., Wang & Wang, 2015). This phenomenon is referred to as lexical alignment. Only one empirical study has investigated the influence that the linguistic complexity…

One of the most researched challenges in learning Spanish is the acquisition and use of the past aspect, namely, the preterit and imperfect. L2 learners encounter this challenge due to differences in how native English and Spanish speakers view past events. Numerous studies on the Spanish past aspect have analyzed L2 learners' past aspectual…

Studies in English as a Foreign Language (EFL) indicate that the use of discourse markers (DMs) in the academic writing of second language learners improves the overall quality of these texts by contributing to their cohesion and comprehensibility (Saif Modhish 2012; Jalilifar 2008; Intaraprawat & Steffensen 1995). However, despite the…

Since sub-sentential alignment is critically important to the translation quality of an Example-Based Machine Translation (EBMT) system, which operates by finding and combining phrase-level matches against the training examples, we developed a new alignment algorithm for the purpose of improving the EBMT system's performance. This new…

This dissertation presents experimental research on speech errors in Tunisian Arabic. The nonconcatenative morphology of Arabic shows interesting interactions of phrasal and lexical constraints with morphological structure during language production. The central empirical questions revolve around properties of "exchange errors". These…

Second language (L2) learners notoriously have trouble using articles in their target languages (e.g., "a", "an", "the" in English). However, researchers disagree about the patterns and causes of these errors. Past studies have found that L2 English learners: (1) Predominantly omit articles (White 2003, Robertson 2000), (2) Overuse "the" (Huebner…

The problem. The purpose of this study is to investigate positive and negative cross-linguistic transfer on EFL learners' phraseological competence in collocations and its relationship to learners' linguistic proficiency. Method. A quantitative study was conducted. Two instruments, multiple choice test and grammaticality judgment test, were…

This dissertation provides an automated scoring method of speech fluency for second language learners of English (L2 learners) based that uses speech recognition technology. Non-standard pronunciation, frequent disfluencies, faulty grammar, and inappropriate lexical choices are crucial characteristics of L2 learners' speech. Due to the ease of…

Although it is widely acknowledged that collocations play an important part in second language learning, especially at intermediate-advanced levels, learners' difficulties with collocations have not been investigated in much detail so far. The present study examines ESL learners' use of verb-noun collocations, such as "take notes," "place an…
