This study investigated the relationship between anxiety and the noticing and integration of language forms in the learning of a less commonly taught language: Arabic. The study was motivated by the need to understand why some learners notice and integrate language forms in their second language speech better than others. Simultaneously, the study sought to understand the mechanisms through which anxiety interferes with second language speech processes. The study included a sample of 80 beginning-level learners of Arabic. The participants were assigned to two treatment conditions, Input and Output. The participants’ language anxiety was measured by the Foreign Language Classroom Anxiety Scale (Horwitz, Horwitz, & Cope, 1986), and their state anxiety during the noticing and production tasks was measured by the Cognitive Interference Questionnaire (Sarason, 1978). In the treatment session, the Output group participants provided an oral description of a picture story, listened to, read, and underlined an Arabic speaker’s description, and re-described the pictures. The Input group participants answered pre-text exposure questions, listened to, read, and underlined the description, and answered post-text exposure questions. An immediate oral production posttest was administered at the end of the treatment session, and a delayed posttest was administered two weeks later. Interviews were conducted following the delayed posttest. The results showed that the noticing and integration of language forms were influenced by the type of anxiety and the nature of the forms. While language anxiety positively predicted learner noticing and integration of the language forms, state anxiety negatively predicted them. Syntactic and discourse level forms deemed more salient and of higher communicative value were more amenable to anxiety effects. No differential anxiety influences on learner noticing were detected across the Input and Output conditions. Pedagogical implications are offered in light of these findings.

This dissertation investigated the occurrence and the effect of incidental noticing in a text-based Computer-Mediated Communication (CMC) environment on enhancing second language learning. Learning proficiency was also examined as a possible intervening variable. This was a quasi-experimental study of sixteen nonnative English speakers from a four-year college in Taiwan, collaborating with sixteen native speaking peers in Texas, via chat agents in order to complete two communicative learning tasks over a two-month period of time. Two posttests were customized for each Nonnative English Speaker (NNES) in order to assess his/her second language learning outcomes. In addition, Language- Related Episode’s (LRE’s) characteristics were expected to serve as powerful predictors of NNES’ correct language learning outcomes. In order to unveil the possible impact of the learner’s language proficiency level and its effect on noticing, eight low- intermediate and eight high- intermediate NNESs were included in the study. The findings revealed that CMC context and native and nonnative English speaking task-based peer interactions promoted learner’s noticing and affected the learning performance of NNESs of different levels. The posttest performance showed that incidental noticing facilitated learner’s linguistic knowledge intake and memory retention. Text-based CMC created a visual and collaborative context which allowed NES peers to offer NNESs of different levels personalized feedback. Among LRE’s characteristics, successful uptake, as a powerful predictor, constantly entered all the models generated by logistic regression analysis, which underpinned the importance of quality uptake during the two-way communication for second language learning. In addition, directness (explicit feedback) and response (elicitation) also appeared in regression models of the subsets of LRE data, which indicated the particular type of feedback needed by learners, especially lower proficiency level ones. In addition, NESs’ involvement also facilitated NNESs’ noticing; NES peers applied elicitation techniques to redirect learner’s attention to the problematic utterances and initiated meaning negotiation. The findings reveal that incidental noticing is beneficial to learning, especially when learners are provided with explicit feedback and incorporate the targeted linguistic items into their language production.

Teachers are being asked to engage in ambitious mathematics teaching in order to reform children's mathematics learning, and it has proven to be challenging. Unraveling the challenges requires understanding the in-the-moment decisions that teachers make while teaching mathematics. The focus of this study is to understand teacher noticing, the ways in which teachers identify, reason about and make decisions in the situations that occur when engaging English language learners in problem solving. Specifically, I used the construct of professional noticing of children's mathematical thinking (Jacobs, Lamb, & Philipp, 2010) to investigate what three bilingual teachers notice as they participate in a teacher study group to analyze and reflect on their experiences in weekly problem solving small groups. What teachers noticed reflected attention to situations in which they struggled to understand children's mathematical thinking and attempts to direct students towards correct problem solving. Teachers' decisions and struggles in engaging children in problem solving also revealed a focus on the role of preparing English language learners be successful for standardized testing. However, looking at student's work in the teacher study group began to help teachers focus on children's mathematical thinking. Implications on continued understanding of teacher noticing, effective mathematics professional development and developing understanding of mathematics teaching to English Language learners are discussed. / text

Engaging Space focuses on arranging as means to engage with space. The adaptive arrangements and spatial negotiations of street vendors provide the stimulus for my inquiry. Noticing the various ways vendors constantly engage spatially has led me to observe the ways spatial practices are adapted to suit various requirements. What might I learn, as an interior practitioner, from the spatial practices of street vendors? How might this be applied to an interior practice, to inform an understanding of adaptive methods to engage with space? Undertaking a practice of vendoring, the projects then become engaging spaces - exploring a practice of arranging to produce interiors.

This study is influenced by phenomenological approaches, and is an inquiry into secondary mathematics teachers’ lived experiences with ephemeral assessment opportunities such as observations of, and conversations with, students. This phenomenon is explored through the use of reflective journals, semi-structured interviews, and focus group interviews. Two layers of analysis were used to better understand the phenomenon. The first layer focuses on emergent themes of what and how teachers think and do in the moment. The emergent themes were interrelated and categorized into eliciting, interpreting, and acting. The second layer focuses on the emergent factors that contribute to what and how teachers think and do during the ephemeral assessment process. The emergent factors were interrelated and categorized into teacher, student, relationships, and contexts. Through the two layers, the complexity of the ephemeral assessment process has been developed.

I examined the development of three Prospective Secondary Mathematics Teachers' (PSMTs) understandings of connections between concepts in Abstract Algebra and high school Algebra, as well as their use of this understanding while engaging in the teaching practice of noticing students' mathematical thinking. I drew on the theory, Knowledge of Nonlocal Mathematics for Teaching, which suggests that teachers' knowledge of advanced mathematics can become useful for teaching when it first helps reshape their understanding of the content they teach. I examined this reshaping process by investigating how PSMTs extended, deepened, unified, and strengthened their understanding of inverses, identities, and binary operations over time. I investigated how the PSMTs' engagement in a Mathematics for Secondary Teachers course, which covered connections between inverse functions and equation solving and the abstract algebraic structures of groups and rings, supported the reshaping of their understandings. I then explored how the PSMTs used their mathematical knowledge as they engaged in the teaching practice of noticing hypothetical students' mathematical thinking. I investigated the extent to which the PSMTs' noticing skills of attending, interpreting, and deciding how to respond to student thinking developed as their mathematical understandings were reshaped. There were key similarities in how the PSMTs reshaped their knowledge of inverse, identity, and binary operation. The PSMTs all unified the additive identity, multiplicative identity, and identity function as instantiations of the same overarching identity concept. They each deepened their understanding of inverse functions. They all unified additive, multiplicative, and function inverses under the overarching inverse concept. They also strengthened connections between inverse functions, the identity function, and function composition. They all extended the contexts in which their understandings of inverses were situated to include trigonometric functions. These changes were observed across all the cases, but one change in understanding was not observed in each case: one PSMT deepened his understanding of the identity function, whereas the other two had not yet conceptualized the identity function as a function in its own right; rather, they perceived it as x, the output of the composition of inverse functions. The PSMTs had opportunities to develop these understandings in their Mathematics for Secondary Teachers course, in which the instructor led the students to reason about the inverse and identity group axioms and reflect on the structure of additive, multiplicative, and compositional inverses and identities. The course also covered the use of inverses, identities, and binary operations used while performing cancellation in the context of equation solving. The PSMTs' noticing skills improved as their mathematical knowledge was reshaped. The PSMTs' reshaped understandings supported them paying more attention to the properties and strategies evident in a hypothetical student's work and know which details were relevant to attend to. The PSMTs' reshaped understandings helped them more accurately interpret a hypothetical student's understanding of the properties, structures, and operations used in equation solving and problems about inverse functions. Their reshaped understandings also helped them give more accurate and appropriate suggestions for responding to a hypothetical student in ways that would build on and improve the student's understanding. / Doctor of Philosophy / Once future mathematics teachers learn about how advanced mathematics content is related to high school algebra content, they can better understand the algebra content they may teach. The future teachers in this study took a Mathematics for Secondary Teachers course during their senior year of college. This course gave them opportunities to make connections between advanced mathematics and high school mathematics. After this course, they better understood the mathematical properties that people use while equation solving, and they improved their teaching practice of making sense of high school students' mathematical thinking about inverses and equation solving. Overall, making connections between the advanced mathematics content they learned during college and the algebra content related to inverses and equation solving that they teach in high school helped them improve their teaching practice.

This dissertation investigated Taiwanese English as Foreign Language (EFL) learners' incidental noticing and their subsequent language learning in relation to learner proficiency level and dyadic type in a text-based computer-mediated communication (CMC) environment. Sixty participants were included to form 30 dyads. At random, eight low-intermediate and eight advanced nonnative English speakers (NNESs) were paired with 16 native English speakers (NESs) to form 16 NES-NNES dyads; another 14 advanced NNESs and 14 low-intermediate NNESs were paired to form 14 mixedproficiency NNES-NNES dyads. The results revealed that the synchronous computer-mediated communication (SCMC) medium could, in general, enhance the occurrence of learners' incidental noticing and their subsequent second language (L2) learning regardless of learners' proficiency levels and dyadic types. No significant differences were found in the amount of the language-related episodes (LREs) produced by the NES-NNES dyads when compared to the NNES-NNES dyads. With regard to the number of LREs generated by the learners of different proficiency levels, the results showed that: (1) in the NESNNES dyads, no significant difference was found between the low-intermediate and advanced learners, and (2) in the NNES-NNES dyads, the low-intermediate learners produced a significantly greater number of LREs than their advanced interlocutors. In terms of the effect of interlocutors' proficiency levels on the number of LREs produced by the learners, the results revealed that: (1) the low-intermediate learners in the NESNNES dyads produced a significantly greater number of LREs than the low-intermediate learners in the NNES-NNES dyads, and (2) the advanced learners in the NES-NNES dyads also produced a significantly greater number of LREs than the advanced learners in the NNES-NNES dyads. With respect to the learners' performance on both posttests, the results of chi-square analyses showed that: (1) no significant differences were found both within and across the two dyadic types, and (2) no significant differences were found between learners of different proficiency levels within and across both NES-NNS and NNES-NNES dyads. Logistic regression analyses revealed that five LRE characteristics (type, source, complexity, proficiency, and successful uptake) in the NES-NNES dyads and three LRE characteristics (proficiency, timing and successful uptake) in the NNES-NNES dyads were shown to be significant predictor variables of the learners' subsequent L2 learning. Successful uptake was the most prevalent predictor variable of the learners' subsequent L2 learning across the two dyadic types. Besides, proficiency appeared to be the second prevalent variable but played a different role in these two dyadic types. Considering the language aspects focused in the LREs, negotiations on the linguistic features of grammar, vocabulary, and spelling were much more prevalent than the pragmatic aspects of language.
