abstract: The advancement of technology has substantively changed the practices of numerous professions, including teaching. When an instructor first adopts a new technology, established classroom practices are perturbed. These perturbations can have positive and negative, large or small, and long- or short-term effects on instructors’ abilities to teach mathematical concepts with the new technology. Therefore, in order to better understand teaching with technology, we need to take a closer look at the adoption of new technology in a mathematics classroom. Using interviews and classroom observations, I explored perturbations in mathematical classroom practices as an instructor implemented virtual manipulatives as novel didactic objects in rational function instruction. In particular, the instructor used didactic objects that were designed to lay the foundation for developing a conceptual understanding of rational functions through the coordination of relative size of the value of the numerator in terms of the value of the denominator. The results are organized according to a taxonomy that captures leader actions, communication, expectations of technology, roles, timing, student engagement, and mathematical conceptions. / Dissertation/Thesis / Doctoral Dissertation Mathematics Education 2017

Its object the study of university education, especially the sense of the traineeship in the course of law. To understand this process sought the meaning of the university source in the Medieval Europe in the XI century and in years 20 and 30 of the last century in Brazil. It shows that as time goes by that institution par excellence of thought and training has been narrowing its horizons in the direction of professionalization, the preparation for the world of work and therefore of learning to do. And so you lose the size of the mark and instituting training process. Hence the need and to interrogate its roots in the university, which was in its infancy to full of life, provoking the intellect, imagination and sensitivity of masters and disciples. That journey led us to question the meaning of education for graduation and put in other words the issue of the stage, the theory and practice and their relationship, not in terms of appearance, as if it were an addition, an addendum, who knows a lot important, but as realities while distinct, different and intrinsically linked. This research asked: what direction the university source in the Middle Ages? What is the meaning of the university located in Brazil? What is the genesis of education for graduation? What is the meaning of the traineeship in the course of law? Seeking unravel these issues, discussion was held with some authors that the sociocultural context facilitated the birth of the university in the Middle Ages as an institution par excellence of thought, the process of implementation of the juxtaposition of Brazilian university faculties, seeking evidence to support the theoretical understanding of education for graduation and the traineeship in the course of law. On the basis of: Coêlho (1987, 1994, 1998 , 1999, 2003, 2004), Chauí (1980, 1996, 1999), Cunha (1980, 1988, 1989, 2000) and others could discuss the meaning of the university, the teaching of graduation, the relationship between theory and practice, the direction of the stage and realize that the university is not exclusive locus of training for work, nor is effective probation role of such training. / O presente estudo intitulado: Universidade, ensino de graduação e estágio curricular no curso de direito resulta de uma pesquisa bibliográfica e documental vinculada à Linha de Pesquisa Cultura e Processos Educacionais. Tem por objeto o estudo da formação universitária, em especial o sentido do estágio curricular no curso de direito. Para a compreensão desse processo buscou o sentido da universidade nascente na Europa medieval no século XI e nos anos 20 e 30 do século passado no Brasil. Mostra que com o passar do tempo essa instituição por excelência do pensamento e da formação vem estreitando seus horizontes no rumo da profissionalização, do preparo para o mundo do trabalho e, portanto, do aprender a fazer. E assim se perde a dimensão instituinte e interrogante do processo formativo. Daí a necessidade e o sentido de interrogar a universidade em suas raízes, o que em seu início a fazia cheia de vida, provocante do intelecto, da imaginação e da sensibilidade de mestres e discípulos. Esse percurso levou-nos a interrogar o sentido do ensino de graduação e a recolocar em outros termos a questão do estágio, da teoria e da prática e sua relação, não no plano da exterioridade, como se fosse um acréscimo, um adendo, quem sabe muito importante, mas como realidades ao mesmo tempo distintas, diferentes e intrinsecamente ligadas. Esta investigação indagou: qual o sentido da universidade nascente na Idade Média? Qual o sentido da universidade implantada no Brasil? Qual a gênese do ensino de graduação? Qual o sentido do estágio curricular no curso de direito? Buscando desvendar essas questões, discutimos com alguns autores o contexto sociocultural que propiciou o nascimento da universidade na Idade Média como uma instituição por excelência do pensamento, o processo de implantação da universidade brasileira pela justaposição de faculdades, buscando elementos teóricos para fundamentar o entendimento do ensino de graduação e do estágio curricular no curso de Direito. Com base em Coêlho (1987, 1994, 1998, 1999, 2003, 2004), Chauí (1980, 1996, 1999), Cunha (1980, 1988, 1989, 2000) e outros foi possível discutir o sentido da universidade, do ensino de graduação, a articulação entre teoria e prática, o sentido do estágio e compreender que a universidade não é lócus exclusivo de formação para o trabalho, tampouco é papel do estágio efetivar essa formação.

This project focuses on the way that new graduate teaching assistants (GTAs) in English develop both their professional identity as teachers and their view of Composition as a field. Drawing on social theories of disciplines (Prior, 1998; Hyland, 2004; Carter, 2007), disciplinary enculturation (Hasrati, 2005; Bazerman and Prior, 2005; Thaiss and Zawacki, 2006), and legitimate peripheral participation (Lave and Wenger, 1991; Wenger 1998), this dissertation examines the transition that composition GTAs undergo during their first year of graduate school. Many of these GTAs move from little or no knowledge of Composition as a discipline to teaching their own writing courses. I focus on GTAs from MA and MFA programs at a large research university in their first year of teaching composition. Using multiple types of data, including in-depth interviews, observations of practicum and mentoring sessions, and teaching genres written by the GTAs, I construct a narrative that shows the role that teaching composition plays in the overall identity construction of graduate students as professionals. This wide data set has allowed me to see the various ways (and various genres) in which Composition is constructed in the lives of new GTAs. Teacher preparation programs offer a variety of assistance, including experience shadowing current teachers, practicum courses and individual or group mentoring. I study the ways these activities help GTAs in one first-year writing program move toward a fuller understanding of and participation in Composition, and how these experiences relate to the overall graduate student experience. Each of these experiences helps move GTAs toward participation as composition teachers. However, the degree to which these GTAs participate in Composition as a discipline has to do with their relationships with mentors and the connections they make between the multiple communities of practice that they must continually navigate. / Ph.

This dissertation addresses three distinct areas of composition: literacy,technology, and teacher training. The research questions I investigate are as follows:Are graduate programs in rhetoric and composition offering preparation for teaching new literacies, especially with digital technology? If so, what is the nature of that training?Does the faculty within a program perceive that training to be effective? Is thattraining perceived to be effective by graduate students?How do individual programs shape their graduate technology training to reflectand manifest specific programmatic agendas and goals?The first two sets of research questions are investigated using survey research methods. The last research question is addressed via case study methods.Using a multi-methodological research design that includes a national survey and two institutional case studies allows me to combine methodologies to draw meaningful conclusions from the data. For example, the survey helps to provide a brief sketch of the state of technology training in rhetoric and composition programs as well as universities, while detailed case studies provide a context that illustrates how the integration of technology into both the university and rhetoric and composition program affects teacher training. The survey demonstrates that many programs do not require courses or workshops that extend special help to those teaching in computer classrooms especially as technology relates to new literacies. Information from the survey also indicates that rhetoric and composition programs have no procedures in place to assess the state of technology training for new teachers and TAs. This dissertation offers one way of assessing technology training.The case studies reveal that the two universities have grand visions and broad technology initiatives. However, a closer look at university mission statements and specific rhetoric and composition programs reveals that the integration of technology is sometimes a less than smooth one. In one case, the department struggles to implement technology at the grass roots level, while another department, despite the inconsistencies apparent at the university level, seems to succeed at both integrating technology and training new teachers to address the new literacies produced by those digital technologies. / Department of English

The employment of International Teaching Assistants in U.S. universities has caused concern with regards to the communicative competence of nonnative speaker TAs in undergraduate classrooms. Researchers such as Rounds (1985), Bryd (1986), Constantino (1986), Tyler (1990), Shaw (1994), and Hoekje and Williams (1994), among others have suggested that more research is needed on the performance of nonnative speaker TAs in specific disciplines.This study is an-attempt to describe the discourse skills of nonnative speaker TAs in Computer Science. The speech event of twelve nonnative speaker TAs was observed and video and audiotaped in teaching lecture and laboratory (programming session) classes. Three native speaker TAs of the same profession were also studied as a comparison group. A profile of each of the TAs was made based on field notes, interviews and student evaluations, to determine TA typologies along Bailey's (1982,1984) classification. The profiles also contributed to grouping the TAs into more skillful and less skillful TAs.The classroom observations were analyzed to determine whether NNSTAs encountered difficulty speaking comprehensibly and explaining the computer science concepts clearly. The other questions investigated included: the apparent degree and ease of student comprehension of the teachers; the amount of student participation allowed and encouraged; the degree of interaction in the classes; and the amount of rapport between the NNSTAs and their students.The rhetorical analysis of the discourse structure of the computer science classrooms revealed two genres. Descriptive discourse was predominant in the lecture sessions and procedural discourse was predominant in the programming sessions. Linguists have shown that there are interesting connections between discourse type and the interlocutor's choice of particular syntactic structures. The investigations in this study showed that the successful NNSTAs complied with these connections and the less successful NNSTAs did not. The discourse problems of nonnative speaker TAs stemmed mainly from their inability to use various cohesive ties and deictic markers appropriately.Finally, the study showed that despite pronunciation and grammatical deficiencies, NNSTAs' success in their classes was determined by their speech acts. The moreinteractive TAs who employed various illocutionary acts to transact disciplinary information were the more skillful TAs. / Department of English

The purposes of this study were to determine whether differences existed between the communication styles and teaching effectiveness, respectively, of native and non-native teaching fellows, as perceived by their undergraduate students. In addition, the study sought to determine whether a positive correlation existed between the final grades and the communication styles and teaching effectiveness, respectively, of native and non-native teaching fellows as perceived by their undergraduate students. In order to carry out the purposes of this study, six hypotheses were tested concerning the perception of native and non-native undergraduate students toward the communication style and teaching effectiveness of teaching fellows in North Texas State University.
