In contexts of first language (L1) acquisition, prediction and adaptation are often viewed as fundamental to the learning process (Rabagliati et al., 2016). One mechanism that has been proposed to specifically account for such adaptive behavior is error-based implicit learning (e.g., Chang et al., 2006). According to this account, speakers…

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,…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

The purpose of this qualitative descriptive study was to explore how elementary STEM teachers describe their use of engaging activities and strategies to help students learn from their mistakes during STEM instruction in the Southeast region of the United States. The theoretical foundation was Bruner's Social Constructivist Theory. Two research…

Automated corrective feedback (ACF), in which a computer system helps language learners identify and correct errors in their writing or speech, is considered an important tool for language instruction by many researchers. Such systems allow learners to correct their own mistakes, thereby reducing teacher workload and potentially preventing issues…

My thesis project reports on a six-week study focused on language-learner preferences for corrective feedback in the classroom. While various types of corrective feedback have been explored in other studies, this study explores learners' perspectives: how much corrective feedback learners may prefer in the classroom, their reported levels of…

A disconnect exists between research that suggests that error making is a critical part of the learning process and school structures that discourage error making. This project sought to investigate and find solutions to error aversion in math classroom learning by considering the effect of classroom error culture (CEC) on learner experience.…

Second Language (L2) teacher education serves as a pivotal site for examining language ideologies that shape teacher candidates' conceptualization and enactments of L2 pedagogy. Informed by the theory of language ideologies (Kroskrity, 2004, 2010) and the concept of language socialization (Ochs & Schieffelin, 1984), this dissertation research…

Despite an extensive amount of research examining students' perceptions of alternative laboratory experiences, little focus has been aimed at the perceptions of adult learners. This two-phase mixed-methods study investigated the preferred at-home laboratory experience, and the factors that played a significant role in the user experiences, of…

Second language learners constitute a significant and expanding portion of the global population and there is a growing demand for tools that facilitate language learning and instruction across various levels and in different countries. The development of large language models (LLMs) has brought about a significant impact on the domains of natural…

The main purpose of this study was to investigate the effectiveness of written corrective feedback (WCF) in a Korean as a foreign language (KFL) context. The assumption that indirect feedback (IF) is more effective for L2 learners with higher-proficiency levels has yet to be fully corroborated, which necessitates substantial research-based…

Nawat, the highly endangered indigenous language of El Salvador, is undergoing a revitalization process. This dissertation, conceived within this context, focuses on the second-language (L2) acquisition of features of Nawat pronunciation by learners who have Salvadoran Spanish as their first language (L1). Specifically, I assess the acquisition of…

While written corrective feedback (WCF) is expected to help learners build new knowledge (Bitchener and Storch, 2016), engagement with WCF is not always satisfactory (Ferris, Liu, Sinha, and Senna, 2013). The purpose of this case study is to explore engagement with WCF by undergraduate of Japanese as a foreign language (JFL) at the elementary…

This dissertation reports on the evaluation of a computer-mediated collaborative animation description task, where synchronous corrective feedback (SCF) serves as the primary source for grammar learning. The evaluation was conducted in an English-as-a-Second-Language (ESL) writing program at a large research university in the United States. Using…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…
