The appropriate amount of first language (L1) and second language (L2) to use in L2 learning has been constantly debated (e.g., Cummins, 2007; Hall & Cook, 2012). This study situates the debate of L1 and L2 use in the context of vocabulary learning from reading. By examining the potential moderating factors on the comparison of L1 and L2…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

This Educational Leadership Portfolio (ELP) sought to address the challenge of optimizing handwriting instructional practices and assessment methods for teaching Chinese as a foreign language (CFL) at St. Andrew's School (SAS). SAS is an Episcopal, co-educational boarding school in Middletown, Delaware. With 18 years of experience as the primary…

An intelligent computer-assisted language learning (ICALL) system is an application to provide users instruction and practice as they learn a second language. In order to be more effective and more widely adopted, ICALL must better align with second language acquisition (SLA) research, moving away from menu-based or fill-in-the-blank exercises and…

Understanding how native speakers acquire the phonological patterns in their language is a key task for the field of phonology. Numerous studies have suggested that phonological learning is a biased process: certain phonological patterns are easily accessed and learned by the speakers, while others show acquisition difficulties. These differences…

The present dissertation explores the effect of exposure to non-native speech via foreign film on non-native speech production and perception. In order to explore potential effects, two main experiments were developed, which examined French production and perception by monolingual native speakers of English before and after exposure to French…

This dissertation consists of three manuscripts. The manuscripts contribute to a budding "methodological reform" currently taking place in quantitative second-language (L2) research. In the first manuscript, the researcher describes an empirical investigation on the application of two well-known effect size estimators, eta-squared (eta…

The promotion of language ideologies, policies and pedagogies that treat languages as separate and hierarchical has become a central concern for critical education scholars. In this case study, I explore how school actors at Colegio Colombiano (CC), an international school in Colombia, engaged with critical approaches to bi/multilingual education…

The dissertation is divided into seven chapters. In the first chapter, I outline the study objectives in relation to the current research on translingual instructional activities in English-dominant schools, describe how I will contribute to this growing body of work, and provide the research questions that guided the study. In Chapter 2, I…

This case study explored internationalization, diversity, and language through the eyes of students, instructors, and administrators at a multicultural community college in Hawai'i. The purpose was to uncover participants' beliefs and attitudes about ongoing campus-wide internationalization efforts as well as to investigate their broader…

This study examined the relationship between Spanish oral reading fluency (ORF) at the end of second grade and students' performance on the third grade ISAT reading test. The major research question guiding this study was: What is the direction and strength of the relationship between performance on the 2nd grade IDEL FLO, a Spanish language ORF…

Recent research in second language acquisition has focused on the effects of group work on learning by examining various factors (i.e., motivation, age, task, gender differences, etc.). One particular factor that has not been heavily investigated is interlocutor familiarity, which is at the forefront of the present study. Two separate classes (in…

Technology has long been a popular means of teaching and learning English as a second language and there is an abundance of research to that effect. To my knowledge, however, none has been conducted specifically on the effect on reading comprehension of English language learners or second language learners reading independently with hypertext…

The purpose of this qualitative study was to examine and gain a clearer understanding of the perceptions of foreign language learning of adult foreign language learners attending a South-West Missouri community college. This study was based on the Multiple Intelligence (MI) theory of Howard Gardner. It examined the perceptions of adult language…

This qualitative case study seeks to identify factors that have a significant impact on the second language proficiency levels of adult English as a Second Language (ESL) learners at a four-year university in Puerto Rico. Current data indicate that a significant percentage of adult ESL learners encounter major difficulties within the process of…
