Language as an Identification Resource in Secondary English Teacher Preparation: An Analysis of Discourses

Tenore, Frank Blake 20 June 2014 (has links)
Teaching, Learning, and Diversity Language as an Identification Resource in Secondary English Teacher Preparation: An Analysis of Discourses Frank Blake Tenore Dissertation under the direction of Professors Kevin M. Leander and H. Richard Milner, IV The topic of the research presented here was teacher educators and teacher candidates talk as an identification resource in the coursework of an undergraduate and Masters level secondary English teacher preparation program. Two research questions framed this study: What identity constructions of English teacher are available in the discourses of secondary English teacher preparation? How are the discourses and available identifications transformed through language use in course meetings? Participants in the study were two English teacher educators, twenty teacher candidates enrolled in two secondary English methods courses at a mid-sized, private, urban university, and five teacher candidates who agreed to participate in interviews and one focus group. Qualitative methods for data collection and analysis were used including semi-structured interviews, classroom observations with video- and audio-recording, constant comparative analysis, and discourse analysis. Findings were that participants talk was connected to prominent Discourses in the fields of English education and teacher education. Talk in the courses created specific identification opportunities for teacher candidates. Teacher candidates accepted, rejected, and transformed the available identifications through specific language use and genres of talk. Findings from this study have implications for structures and practices in teacher education and contribute to theory building of how teacher candidates become teachers who identify, or not, with particular conceptions of English teacher.

IS THIS SAMPLE UNUSUAL?: AN INVESTIGATION OF STUDENTS EXPLORING CONNECTIONS BETWEEN SAMPLING DISTRIBUTIONS AND STATISTICAL INFERENCE

Saldanha, Luis A. 26 July 2004 (has links)
This study explores the reasoning that emerged among eight high school juniors and seniors as they participated in a classroom teaching experiment addressing stochastic conceptions of sampling and statistical inference. Toward this end, instructional activities engaged students in embedding sampling and inference within the foundational notion of distributions of sample statisticspatterns of dispersion that one conceives as emerging in a collection of a sample statistics values that accumulate from re-sampling under essentially identical conditions. The study details students engagement and emergent understandings in the context of instructional activities designed to support them. Analyses highlight these components: the design of instructional activities, classroom conversations and interactions that emerged from students engagement in activities, students ideas and understandings that emerged in the process, and the design teams interpretations of students understandings. Moreover, analyses highlight the synergistic interplay between these components that drove the unfolding of the teaching experiment over the course of 17 lessons in cycles of design, engagement, and interpretation. These cycles gave rise to four interrelated phases of instructional engagements: Phase 1: Orientation to statistical prediction and distributional reasoning; Phase 2: Move to conceptualize probabilistic situations and quantify unusualness; Phase 3: Move to conceptualize variability and distribution; Phase 4: Move to quantify variability and extend distribution. Analyses reveal that students experienced significant difficulties in conceiving the distribution of sample statistics and point to possible reasons for them. Their difficulties centered on composing and coordinating objects into a hierarchical structure with actions in imagined re-sampling scenarios that involve: a population of items, selecting items from it to accumulate a sample, recording the value of a statistic of interest, repeating this process to accumulate a collection of values, structuring such collections and conceiving patterns within and across them in ways that support making statistical inferences.

LEARNING BY EXPLAINING: THE EFFECTS OF SOFTWARE AGENTS AS LEARNING PARTNERS

Holmes, Jeffrey Thomas Grant 25 November 2003 (has links)
Although prior research as shown that generating explanations encourages students to learn new content with deeper understanding and to monitor their own comprehension more effectively, helping students learn how to explain properly remains a significant challenge. This study investigated the use of software agents as learning partners in an activity where students generated explanations about river ecosystem concepts. <p>The results of the experiment demonstrated that software agents can have a positive impact as learning partners in a virtual world environment. It was found that the agents encouraged the use of explanation resources designed to help students generate more effective explanations. Students working with the agents generated deeper explanations than students who did not interact with an agent. A summary report of student explanations produced for the participating teacher was perceived to be a useful source of feedback.

Role-based learning: Considering identity and practice in instructional design

McClarey, Bryan Schulze 14 December 2004 (has links)
Research in the learning sciences has moved toward a focus on the conditions in which knowledge is learned and applied (e.g. Bransford, Brown, & Cocking, 2000; CTGV, 1997). However, instructional designs still tend to focus primarily on the material or physical conditions for applying knowledge, not the social or personal context of that knowledge (Lave & Wenger, 1991; Hay & Barab, 2001). This study takes as its premise that learning to perform a professional role in a domain involves more than the acquisition of knowledge propositions in that domain; learning a role transforms identity and practice (Wenger, 1998). For this dissertation, a learning experience is designed and evaluated with an explicit focus on learning a role for new employees at a health care corporation. The designed intervention used intentional language and multimedia stories to guide the new employees adoption of their role. The design had the effect of facilitating understanding of the role as measured by pre- and post-writing measures and interviews. Based on the study, trajectories of role change are described and design principles for role-based learning are proposed.

An Investigation of Content Knowledge for Teaching: Understanding its Development and its Influence on Pedagogy

Silverman, Jason 18 July 2005 (has links)
This study explores the complex relationship between teachers understandings of mathematics and their classroom practices. The study details students engagement in a segment of a university course designed to position pre-service teachers to develop a coherent understanding of functions as covariation of quantities. With regards to this instruction, this study was guided by two research questions that dealt with understanding (a) the pre-service teachers mathematical development and then (b) how the pre-service teachers emerging understanding of function as covariation impact how they envision and enact instruction, with particular emphasis on the pre-service teachers ability to orchestrate conceptual conversations about significant mathematical ideas. Analyses highlight the fact that one teaches what they know pre-service teachers particular understandings of mathematical content have a significant impact on their pedagogical conceptualizations of the content. It is these pedagogical conceptualizations of content and the related images that serve to guide the pre-service teachers decisions and instructional actions. The study concludes with suggestions for ways in which appropriate pedagogical conceptualizations of the content might be developed.

TEACHERS UNDERSTANDINGS OF PROBABILITY AND STATISTICAL INFERENCE AND THEIR IMPLICATIONS FOR PROFESSIONAL DEVELOPMENT

Liu, Yan 23 July 2005 (has links)
Probability and statistical inference are important ideas with a remarkably wide range of applications. However, psychological and instructional studies conducted in the last two decades have consistently documented poor understanding of these ideas among different population across different settings. The purposes of this dissertation study are to understand teachers understandings of probability and statistical inference; and to develop theoretical frameworks for understanding teachers understandings. To this end, our research team conducted an eight-day seminar with eight high school statistics teachers in the summer of 2001. The data we collected include videotaped sessions and interviews, teachers written work, and researchers field notes. My analysis of the data revealed that: 1) There was a complex mix of conceptions and understandings of probability and statistical inference, both within individual teachers and among the group of teachers, that are often situationally triggered, which are often incoherent when the teachers try to reflect on them, and which do not support their attempts to develop coherent pedagogical strategies regarding probability and statistical inference; 2) teachers conceptions of probability and statistical inference are highly compartmentalized: They did not understand probability and statistical inference as a scheme of interconnected ideas, but rather, ideas that are isolated from one another; 3) many teachers had a conception of learning as knowing how to solve problems, and teaching as displaying the expertise of problem solving. These conceptions of learning did not support their engagement in reflective conversations about the ideas in probability and statistical inference. The implications of these results include: 1) Understanding statistical inference and teaching effectively entails a substantial departure from teachers' prior experience and their tacit beliefs; and 2) the goal of teachers professional development should be helping the teachers develop understandings of probability and statistical inference as a scheme of interrelated ideas by exerting a great amount of coerced effort in helping teachers develop the capacity and orientation in thinking of a distribution of sample statistics.

AN ANALYSIS OF THE EMERGENCE AND CONCURRENT LEARNING OF A PROFESSIONAL TEACHING COMMUNITY

Dean, Chrystal Ollis 24 July 2005 (has links)
The purpose of this dissertation was to document the development of a professional teaching community and the means of supporting its emergence and concurrent learning as situated in the institutional context of the school district. In this process, I related the realized learning trajectory of this professional teaching community and of the participating teachers to both the means by which it was supported and organized, and to the institutional setting in which the teachers worked. The results of this analysis will generalize to other cases in that it will enable researchers and teacher educators to adapt the means by which the learning of the professional teaching community was supported to the organizational characteristics of the school systems in which they are working in a conjecture-driven manner.

An Analysis of Statistical Reasoning

Saslow, Laura 26 July 2005 (has links)
This study analyzes the development of statistical reasoning during several mathematics classes of an intact fourth-grade classroom. The teacher and her students were members of a multi-year teacher-researcher collaborative effort. In all, fourteen class sessions were videotaped, one on January 27, 2000 and the rest from April 6, 2000 to May 18, 2000. Data sources include this video recording, made using a single camera, and rough transcripts of the class talk, written at the time of the videotaping. In the course of the lessons, the students and their teacher worked through statistical ideas and problems about data describing differently sized bubbles, people, and plants. The lessons were analyzed several different ways, including looking at the order and connectivity of turns of talk, the frequency of mention of different topics, the comparisons made between different data sets, and how arguments were formed about expectations and distributions.

Enactive Modeling as a Catalyst for Conceptual Understanding: An Example with a Circuit Simulation

Holton, Douglas Lee 27 July 2006 (has links)
This research explored how allowing students to actively control an electrical circuit simulation in real-time helps them better understand the complex behavior of electrical circuits. Many students, even at the college level, have misconceptions about electricity that make the subject more difficult to teach and learn via traditional methods such as lecture or textbooks. In this study, students used a unique real-time control interface to an animated circuit simulation in order to enactively model how an AC voltage source controls the current flow in a circuit. In enactive modeling, the student is an agent participating in the behavior of a dynamic system and is controlling one or more temporal aspects of the changes occurring in the system. After only a 30 minute tutoring session with the circuit simulation, students significantly gained in their understanding of some difficult concepts about circuit behavior, as measured by a multiple choice conceptual test. In particular there was evidence that students were able to overcome common misconceptions about the temporal behavior and flow of electrical current.

Alternative instructional strategies for low-literate adults: An investigation of the effects of static and dynamic visuals on learning outcomes

Cohen, Bruce B. 31 July 2007 (has links)
The purpose of this study was to assess the effects of three instructional media on learning among adults in developing countries. Participants included 90 women from Central and South America randomly assigned to one of three modes of instruction: narrative only, narrative plus still images, or narrative plus video segments. At the conclusion of a presentation in one of the three modes of instruction, each participant was tested on four categories of learning: recall of facts, recall of procedures, demonstration of stepwise procedures, and demonstration of conditional procedures. Test results revealed that the addition of still images to narrative had no bearing on the recall of facts but had a positive bearing on the recall and demonstration of procedures for participants with seven or more years of schooling. The addition of video to narrative, by comparison, appears to have raised scores for all participants with respect to recall and demonstration of procedures -- raising scores for participants with zero to six years of schooling more dramatically and more consistently than those with seven or more years of schooling.
