Memory retrieval is well known to modify retention of not only retrieved material, but also related, non-retrieved material. This dissertation consists of two manuscripts that investigated retrieval phenomena in the learning of foreign language vocabulary and science education material. The testing effect--the retention benefit of practicing…

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…

This dissertation developed a new learner corpus of Japanese and introduced an error and linguistic annotation scheme specifically designed for Japanese particles. The corpus contains texts written by learners who are in the first year to fourth year university level Japanese courses. The texts in the corpus were tagged with part-of-speech and…

When acquiring a second language, learners must become able to perceive the difference between novel sounds ("discrimination") and also associate strings of sounds with distinct vocabulary items ("lexical encoding"). Recent research has questioned whether discrimination is a sufficient or necessary condition for encoding, and…

This study investigated factors that are related to student success in using and learning from written corrective feedback (WCF). Focusing on learner affective variables and a student writing corpus collected over the span of a semester, different types of feedback and errors were investigated. Previous studies have focused on one or, at the most,…

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…

Generalization is the ability to apply regularities to novel instances, for example, correctly guessing that the plural for the novel English word 'wug' should be 'wugs'. Early language learners make overgeneralization errors like 'mouses', applying regularities beyond their attested uses. Theories concerned with the question of how learners learn…

Discourse markers (DMs) are linguistic forms characterized by their use as conversation organizers or pause fillers (Fox Tree, 2010). Although used frequently in both speech and writing, DMs are not often taught in L2 classrooms, despite incorrect usage causing potential misunderstandings (Polat, 2011). Additionally, L2 learners have been observed…

We examined spelling errors patterns, cohesive ties, and syntax features in English and Spanish essays written by Spanish-English emergent bilinguals in Grades 1, 2, and 3 (N = 278; 51% female) enrolled in either English immersion or English-Spanish dual immersion programs. In Study 1, we addressed whether students made consistent spelling errors…

Writing proper English sentences poses a significant challenge for Arabic-speaking postsecondary students studying English as a Foreign Language (EFL) due to substantial differences between Arabic and English syntactic structures. This basic qualitative study explored the perceptions of Arabic-speaking EFL learners at an Arabian university…

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…

This dissertation focuses on adult emergent literacy learning of English, which is underexplored relative to children's literacy learning and fully literate L2 learners of English. Although research has pointed to the fact that "adults often arrive [to literacy programs] with prior experiences of authentic reading and writing" (Lytle,…

Learning to read in English is difficult for adult English language learners due to their diverse background, their level of experience with literacy in their first language, and their reason and desire for wanting to learn to read in English. Teachers of adult language learners must consider the educational and language experiences of adults…

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…
