THE EFFECTS OF PROFESSIONAL DEVELOPMENT ON PRESCHOOL TEACHERS MATHEMATICS INSTRUCTIONVarol, Filiz 09 September 2009 (has links)
The primary purpose of this study is to critically investigate the association between preschool teachers mathematics instruction and their participation in a preschool mathematics intervention program in terms of three perspectives. First, the study examined whether preschool teachers participation in the preschool mathematics intervention program had significant effects on implementing mathematical activities more often and with higher quality in their classrooms. Second, within the treatment group, the study examined the effects of exposure to professional development on the amount and quality of mathematics activities the teachers provided for their students and their level of implementation of the curriculum. Third, the study sought to examine the effects of teachers overall satisfaction with the curriculum and the professional development support they received on the amount and quality of math instruction and their curriculum implementation level. Although participation in a professional development increased the quantity and quality of preschool teachers mathematics instruction, the results raised important issues for future research to investigate in terms of individual contributions of professional development models on preschool teachers mathematics instruction.

Preparing Effective Teachers of English Language Learners: The Impact of a Cross-Cultural Field ExperienceTeague, Brad L. 04 March 2010 (has links)
This study explored the role of cross-cultural field experiences in the preparation of teachers of English Language Learners (ELLs). The case is made that direct and sustained contact with linguistically and culturally diverse individuals leads to unique types of learning that cannot be replicated in the university classroom. The study took place at a prestigious private university in the southeastern United States, and focal participants included six undergraduate education majors. Each of the participants spent at least 15 hours at a designated site (or sites) in the community and was required to interact with ELLs and to participate in a number of non-English-language activities. Using the lens of sociocultural theory, I traced the development of participants knowledge and beliefs regarding ELLs throughout the experience. Data sources included demographic and background questionnaires, pre- and post-experience surveys, reflection papers, class observation notes, and transcripts of individual and focus-group interviews. Data analysis was ongoing throughout the study and followed the constant-comparative method.
Findings indicated that participation in the cross-cultural field experience resulted in increased knowledge and more positive beliefs among most of the teacher candidates. For example, the participants made explicit connections between theories and concepts covered in coursework and the personal experiences of ELLs with whom they interacted. Significantly, they commented that combining coursework with real-life experiences led to deeper and more meaningful learning. The candidates also gained familiarity with local community resources, they learned about group-specific cultural practices, and they articulated culturally relevant instructional practices grounded in their out-of-class experiences. Many of them likewise evidenced more positive and affirming beliefs toward ELLs, they challenged many of the unfounded assumptions with which they had begun the course, and some of them became more comfortable being in a non-familiar setting and interacting with diverse individuals. Overall, the study demonstrated a number of specific types of impact that direct interaction with linguistically diverse individuals can have on prospective teachers.

Evaluating Math Recovery: The Impact of Implementation Fidelity on Student OutcomesMunter, Charles 17 September 2010 (has links)
In this dissertation, I report an analysis of the relationship between student outcomes and fidelity of implementation of Math Recovery, an unscripted, pullout, tutoring program intended to increase the mathematics achievement of low-performing first graders. The work I describe was conducted as part of a larger evaluation study of the intervention. Two research questions guided the conduct and analysis of the larger evaluation study: 1) Does participation in Math Recovery raise the mathematics achievement of low performing first-grade students? 2) If so, do participating students maintain the gains made in first grade through the end of second grade? The work documented in this report was driven by a third question: 3) What is the relation between fidelity of implementation of the program and student outcomes at the end of the school year in which students received tutoring? I detail the process of developing and testing instruments for assessing implementation fidelity of Math Recovery. In doing so, I provide a concrete account of how recent conceptions and standards of fidelity assessment were applied to the FOI assessment of MR, including (a) identifying the interventions program theory and core components; (b) creating operational definitions of the interventions core components; (c) developing coding instruments; (d) hiring and training coders; (e) instituting a sampling frame sufficient for generalizing fidelity findings to the study population; and (f) determining the reliability and validity of the instruments. In addition to reporting the findings of my analyses, I provide a discussion of key aspects of the work that were particularly helpful in assessing implementation fidelity of Math Recovery in order to illustrate how these steps might be accomplished in fidelity studies of other unscripted interventions.

New Literacies, New Contexts? A Theoretical Definition of Reading ContextTiedemann, John Patrick 15 April 2011 (has links)
NEW LITERACIES, NEW CONTEXTS? A THEORETICAL DEFINITION OF READING CONTEXT
J Patrick Tiedemann
This dissertation presents research that leads to a new conceptualization of reading context. The question that evokes this reconceptualization is whether the concepts of context that inform reading theory, research, and pedagogy effectively describe the complexity of reading in the age of technologically-mediated, multimodal reading. I contend that current understandings of reading context are atheoretical and outdated. This dissertation contributes to reading theory and research by providing a theoretically defensible conceptualization of reading context under the current conditions, a new theoretical definition that is useful for understanding print-based alphabetic reading and the rapidly changing new reading practices developing in the current technological landscape. It contributes to reading theory by examining in depth a central idea in the literature that has until now gone undertheorized.
Each chapter of this work is a round of analysis that defines a number of constituents that comprise reading context. Chapter 3 begins with an analysis of reading context according to cognitive reading theories. This school of thought provides my construct with the sub-categories orthography, syntax, and semantics as well as Rosenblatts transactional understanding of the importance of an individuals history of social and cultural experience. Chapter 4 examines the contextualizing dialectical structure of activity according to Cultural Historical Activity Theory, Deweys theory of the transactional and contextual situation, and context according to Contextualism. These three complimentary traditions lead to a working definition of context as the relational network of phenomena (material, linguistic, social, and conceptual) that gives an object its identity and meaning. Chapter 5 is an analysis of the constituents of context according to New Literacy Studies. NLS theory and research provide my construct with the sub-categories society (local and historical), culture (local and historical), history, politics, the material environment, time, and space. These are synthesized with the constituents derived from the previous rounds of analysis to provide my final definition of context that I then use to explore how the mediation of networked communication technologies alters reading context.

NONFICTION WRITING IN PREKINDERGARTEN: UNDERSTANDINGS OF INFORMATIONAL TEXT FEATURES AND USE OF SCIENCE JOURNALSFlushman, Tanya 25 July 2012 (has links)
This study provides qualitative findings about informational text writing in a prekindergarten classroom. First, I examined childrens understandings of informational text features. Second, I analyzed how science journals, as informational texts, were created in social interaction. Lastly, I examined the nature of the childrens journals entries. The participants for this study were 17 low-income children in a public prekindergarten in the mid-South. Data collection included classroom observations by the researcher, videotape of classroom instruction and journal entries. Children were given an Informational Text Interview (ITI) to assess understandings of informational text genre features. An analysis of the ITI showed that children had different levels of interaction with the informational text: by naming key features in the photographs, by responding to how the genre features were functioning and by taking a meta-stance towards the text that considered authorial intention. An analysis of journal writing sessions showed that journals were produced through providing demonstrations, making authentic invitations and accepting childrens approximations. Analyses of focal journal entries showed that children used structures and visual and textual elements of informational texts including diagrams, captions and labels. Children at all stages of writing development were able to produce semantically accurate labels and captions for images.

Dimensions and Levels of Students' Understanding of Area MeasurementZhou, Wenyan 16 April 2012 (has links)
Based on a synthesis of prior research, this study proposes a three dimensional framework to describe the cognitive achievements important for understanding area measurement in upper elementary school years (grade 4-6). Levels within each of the three dimensions were specified. Items were developed to elicit performances indicative of those levels. To refine the items prior to field testing, cognitive interviews were conducted with 28 students (grade 4-5) recruited from two schools in the southeastern US. Sixty items were selected and revised based on results of the cognitive interviews. These 60 items were then piloted with a sample of 267 students (grade 4-6) recruited from the same schools from which participants of the cognitive interviews were recruited. The psychometric properties of the items were analyzed using both classical methods and item response theories (IRT) models. The IRT analyses indicate that the three-dimensional model fits better than the one- and two-dimensional models. Furthermore, the order of the items in general follows the order of the levels they targeted. Quality of the assessment was examined regarding both its reliability and validity. While there might be some concerns of gender DIF in a few of the items, in general the psychometric properties of the assessment were satisfactory. In summary, the results of this study supports the three dimensional framework for describing cognitive achievements in understanding area measurement.

Epistemic, Cognitive Practices in Statistical Consultations: An Actor Network ApproachWright, Kenneth Allen 25 September 2012 (has links)
Actor Network Theory (ANT) is invoked in order to characterize the performance of objects in demonstrations around representational forms, examples of which include tables, equations, graphs, and embodied, narrative assemblies. Statisticians and medical scientists typically depict patterns within populations of objects from the clinic or the laboratory and bind features in (local) representational forms to (global) descriptions of objects elsewhere. Objects perform in the sense that consequential decisions or knowledge claims are posed as contingent upon what these objects do as revealed in impending representational forms. Within their cognitive practice, states of affairs are true because networks of relations have been forged to hold things together. This cognitive practice of demonstrating is shown to be historically rooted and special to the sciences. Drawing from Cognitive Ethnography, learning is characterized here in terms of adaptation within a complex system that includes people and infrastructure. The empirical cases presented here are interpreted from this perspective of ANT in order to provide images of the cognitive practice of learning and images of the cognitive practice of knowledge-production. These empirically-based descriptions provide relevant images of (1) modeling practices in schools, (2) the agency of humans with respect to the agency of mathematical objects with which they interact, and (3) the dialogic nature of learning scientific concepts and scientific practice.

In-service learning of teachers of ELLs: An ecological perspectiveRose, Brian C. 16 April 2012 (has links)
This study aimed to investigate the influences that impact in-service teachers of ELLs professional development decisions. In this dissertation, I followed the work of four in-service ELL teachers in two different school districts to determine the nature of the various institutional systems within which their work occurred and the impact these systems had on the teachers continued learning. In blending sociocultural theory and an ecological perspective, I was able to view the interactions teachers had with their peers and larger systems of activity (i.e., the school district, the school-site, the classroom, and the legislative arena) as mediating factors in the decisions the ELL teacher made in their professional development. Through interviews, classroom observation, and document and artifact collection, I uncovered the ways in which these systems linked to exert influence on the participating teachers. I found that these teachers engaged in a wide variety of professional development activities, that they responded to various institutional influences, and that they translated what they learned into classroom practice. Further, this study suggests that the linkages that exist between the various systems in which teachers participate determine the professional development ELL teachers choose, as these linkages define the roles and responsibilities ELL teachers take up in their schools and districts. In sum, this study highlights the impact the specific contexts within which teachers work have on the professional development choices ELL teachers make.

Changing Local Practice for Good: Walking Scale Geometry as Designed Disruptions for Productive HybridityMa, Jasmine Y. 23 July 2012 (has links)
This dissertation presents the first iteration of a design study that investigates an instructional setting that I call Walking Scale Geometry (WSG). WSG tasks are geometry problems that are meant to be solved at very large scale, outdoors, using everyday materials, by groups of students. This setting disrupts typical classroom mathematics in four ways: a) problems are solved outdoors, in large open spaces, rather than in classrooms at desks; b) classroom representational and conceptual tools like paper and pencil, rulers, protractors, and hands are replaced with everyday materials like ropes, lawn flags, and students whole bodies; c) students see geometric figures from intrinsic perspectives, rather than extrinsic, birds-eye- views; d) the division of labor is such that problems cannot be solved individually. WSG is designed to constitute a mediating setting that supports the recruitment of resources for learning and doing mathematics, and access to participation (opportunities to learn) not typically available in classroom instruction. Students shared experiences in the WSG setting can be leveraged in classroom instruction to support productive hybridity, improving geometry learning for all students.
I compare implementation of WSG tasks in two different instructional contexts: an urban seventh grade mathematics class and a summer enrichment course for high achieving rising ninth and tenth graders. Data include audio, video, and photographic records of design and instruction, field notes, student work artifacts, and interviews. Micro-analysis focused on students joint, whole-bodied accomplishment of WSG tasks and the resources that students recruited for participation and problem-solving. I demonstrate that aspects of the multi-party, whole-bodied activity, the use of everyday materials in inventing new representational practices, and the interconnectedness of the inscriptional system support access to participation with a variety of forms of mathematical engagement, and make available novel resources for problem-solving. I conclude with comments regarding the next iteration of WSG task design, classroom instruction that can legerage students experiences in the WSG setting, and thoughts about what a design for ensemble mathematics might entail.

Influences of Instructional and Emotional Classroom Environments and Learning Engagement on Low-income Children's Achievement in the Prekindergarten YearAydogan, Canan 24 July 2012 (has links)
This study described instructional and emotional classroom environments, as well as the learning engagement of children involved in various classroom tasks, and explored whether variability in childrens classroom experiences was related to childrens gains in academic skills from fall to spring of the prekindergarten year. Participants were 57 classrooms and their children and teachers located in state-funded prekindergarten and Head Start classrooms. Classroom instructional practices and emotional tone in combination were found to be related to childrens achievement gains. Also, the strength of the influence of instructional classroom practices on achievement gains was dependent on the affective tone of the teacher and assistant. In classrooms with more positive emotional tone, children benefited more from high-level instructional support. The amount of and the complexity of childrens learning engagement observed in a classroom predicted childrens academic gains. Also, children who were more frequently engaged in learning and those who were engaged in more complex learning activities had greater gains than their peers within the same classroom who demonstrated relatively infrequent and less complex engagement in learning activities. It was expected that classroom learning engagement would mediate the effect of classroom environment on childrens achievement gains. The hypothesized mediation was not supported. Also, the exploration of the moderating effect of childrens initial academic skills on the relationship between classroom environment and achievement gains yielded non-significant finding. These findings have implications for understanding the role of classroom experiences in the improvement of economically disadvantaged childrens success in school.
