Identity through dress in virtual environments

Makryniotis, Thomas January 2013 (has links)
The purpose of this thesis is to examine the formation of identity through dress in virtual environments, and to establish connections between identity, fashion, and virtual reality by means of language and semiology. The notion of identity through fashion in virtual environments is examined, with fashion as a factor in identity formation through dress as analysed in structuralist terms. The virtual aspect is used both as a literal field, i.e. the medium of video games and social networks that involve virtual avatars, and as theoretical testing ground from which to derive new results on the nature of dress and many of the aspects of clothing and fashion. The practical outcome of this research, a video game based on dress and narrative, serves as an applied experiment of the three main themes in this thesis and the relations and interactions between them, as well as a testing tool with which to challenge in a practical way the theories and speculations formed in the thesis. My methodology is based on structuralism and post-structuralism in the fields of linguistics, psychology and anthropology, with particular application to the visual media and virtual reality. I am using a post-structuralist approach as it has been the most dominant discourse of replacing economic and social (power) relations with codes and the interplay between signifiers and signifieds. This, I find, is the most appropriate method for analysing both virtual systems and fashion, because, on an atomic level, they both depend on variables such as words and numbers. The code is therefore the common denominator of both disciplines. Furthermore, both disciplines use narrative for their proper function, video games for their back story and motivation of the player, and fashion for its advertising and promotion, as well as through archetypes and symbols. Fashion in this context works as a catalytic agent between post-structuralist codes in modern media as texts, and video games.

Professional Development for the Use of iPads in Instruction

Poore, Daphne Marie 01 January 2015 (has links)
Elementary teachers at a school in the southeastern United States received iPads and iPad training to improve teaching and learning in the content subject areas. Despite the iPad training provided by district technology personnel, teachers expressed a need for more content-specific training. Teachers need adequate and appropriate professional development to assist in preparing integrated computer-based technology instruction to increase student academic achievement. The purpose of this qualitative bounded case study was to explore the descriptions of 10 purposely selected 4th and 5th grade teachers who used iPads in content subjects and 1 instructional technology facilitator who provided district iPad training regarding the district's iPad professional development and implementation in instruction. The theoretical support for this study was the technological pedagogical content knowledge framework that provided an interaction among technology, pedagogy, and content knowledge. Data were collected from face-to-face interviews and lesson plans. Inductive analysis was used with hand coding to discover themes. Teachers recognized the need for ongoing professional development and collaboration with colleagues to create content-specific iPad integrated lessons. Based on these findings, a project was designed to provide teachers with a 3-day professional development to include modeled lessons, collaboration with colleagues, a shared Google Drive folder, and a schedule for ongoing professional development. These endeavors may promote positive social change by providing ongoing content-specific iPad professional development for elementary teachers that could improve computer-based technology instruction and student learning in content subject areas.

The effects of microcomputers on the mathematical skills of low-achieving students

Copley, Charlotte Evans 01 January 1990 (has links)
The purpose of this study was to determine the effectiveness of using the microcomputer to improve mathematics achievement for those students who did not pass the mathematics section of the State Literacy Passport Test in Grade 6.;The sample consisted of nine classes of seventh grade students who had not passed the LPT and whose parent(s) committed to the five week summer program. Students were assigned randomly to the nine teachers. The teachers were then assigned randomly to either the microcomputer or non microcomputer group with five being assigned to the microcomputer group. to control for teacher variability staff development and a detailed teacher's guide were provided. The topics covered in both groups were those which are addressed on the State LPT: numbers and numeration; relations and functions; computation with whole numbers, decimals, and fractions; measurement and geometry; and applications. The lessons for both groups included identical teacher directed activities. Students in the microcomputer group were assigned in pairs to a microcomputer and spent approximately 20% of the time using the microcomputer for follow-up activities whereas the students in the non microcomputer group worked on more conventional follow-up activities such as games and puzzles. The students attended classes for two and one-half hours, four days a week for five weeks.;A literacy passport test developed by the project director which was previously examined for content and concurrent validity and reliability was the posttest assessment. The pretest assessment was the State LPT.;The major findings of the study were: (1) Students in the microcomputer group scored significantly higher on the posttest for the total test and for the subtests of--computation with decimals, computations with fractions, and measurement and geometry. (2) Students in the microcomputer group experienced significant posttest gains on the subtest on computation with whole numbers but the posttest differences were not significant (p {dollar}<{dollar}.05). This was due to the significant differences in pretest scores in favor of the non microcomputer group.

Factors contributing to the use of computer-based information systems in student services

DeMaio, Genene Marie 01 January 1990 (has links)
The purpose of this study was to determine what factors facilitate and what factors inhibit computer use in the Student Affairs Divisions of James Madison University (JMU), Virginia Polytechnic Institute (VPI), and Mary Washington College (MWC).;The population for this study was student affairs officials and related personnel deliberately selected from three Virginia public institutions.;The following conclusions were drawn from the findings of this study. (1) MWC is in the beginning stages of automation, JMU is moving in the direction of state-of-art technology while VPI's current status has reached the level regarded as state-of-art. (2) The status of CBISs at MWC, JMU, and VPI is affected by the time period in which automation occurred. (3) Student affairs' users at MWC, JMU, and VPI perceive CBISs positively. (4) Respondents believe using CBISs on the job simplifies tasks, helps monitor data flow, increases efficiency, makes output professional, makes data timely and accurate, improves the communication process, and does not significantly affect changes in policy. (5) No significant organizational changes have occurred at MWC or JMU while several organizational changes were identified at VPI. (6) The institution's mission and size influence the direction institutions take in regard to computer technology. (7) Respondents were satisfied with the microcomputer support and training received. (8) All users mentioned mainframe computer support was slow and uneven and many outside influences seem to impact the quality of this service. (9) It is clear that at JMU and VPI the integrator's role positively affects the use of computers. (10) The role, professional background, and personal characteristics of integrators were indentified and summarized. (11) Institutions of higher education should identify the integrators on their campuses and promote and support their role. (12) Top leadership commitment plays a crucial factor in facilitating computer use. (13) The lack of long range plans for the improved use of computers do not significantly affect the use of CBISs at MWC, JMU, or VPI.;Since very little research has been conducted on Student Affairs Divisions' use of CBISs, future research should focus on how data collected on students improve the effective operation of student affairs offices.

Student attitudes, learning effectiveness, and costs/benefits pertaining to military logistics courses offered in the residence, on-site, and satellite television modes of instruction

Fenn, Raymond C. 01 January 1995 (has links)
Using period newspapers and books, mercantile correspondence, Spanish imperial archives, and the colonial records of the Caracas City Council, Consulado, and Venezuelan Intendancy, this dissertation highlights the enterprises of those who profited from sustaining the Spanish Empire in its frail and debilitated state. Whether they had prospered from or merely survived the commercial revolutions that shook the Atlantic World after 1789, all merchants and traders calculated the economic consequences of South American independence and encouraged their contemporaries to do so too.

Students with autism: A light/sound technology intervention

Woodbury, Patricia Powell 01 January 1996 (has links)
The purpose of the study was to investigate the effectiveness of light/sound technology to promote sensory integration which facilitates the learning capacity of children with autism by reducing their high state of arousal, increasing time on task and decreasing acting-out behaviors. This research extended the work of A. Jean Ayres and Lorna King who theorized that the autistic individual's brain does not register, modulate or integrate sensations that most people notice; auditory and visual inputs are ignored more than other types of sensory stimuli. This study utilized light/sound technology to stimulate and desensitize these sensory channels to facilitate processing of incoming stimuli. The technology was furnished by Dr. Harold Russell and was programmed with a microchip to control the frequency patterns. Twelve subjects were selected to participate in this eight week study; only five subjects completed. They represented schools in the Tidewater region of Virginia and Illinois. Inattention, Impulsivity, and Hyperactivity were assessed with The Attention Deficit Disorder Evaluation Scale-Home and School Versions. Comparison of the results of these measures and qualitative data were incorporated into case studies. There was improvement noted in social skills, attention and on-task behavior. The results are supportive of research conducted with learning disabled and AH/HD students conducted by Drs. Carter and Russell.

Teachers' Perceived Influences on Technology Integration Decisions: A Grounded Theory on Instructional Decisions after Professional Development

Greenhaus, Karen Larsen 01 January 2014 (has links)
This qualitative grounded theory study explored teachers' instructional decisions around planning and practice for technology integration after participation in professional development. The purpose of this study was to determine how a long-term hybrid professional development experience influenced, if at all, math teachers' instructional decisions to integrate The Geometer's Sketchpad into their planning and classroom practice. There are several components for effective professional development suggested in the research literature. Professional development that is sustained over long periods of time, connected to teachers' practice, and provides active engagement in learning by participating teachers' is more likely to result in effective implementation of new skills and pedagogical practices (Darling-Hammond & McLaughlin, 1995; Polly & Hannafin, 2010). The seven participants in this study all experienced a seven-month hybrid professional development that was designed using these research-recommended components. The study took place ten months after the professional development. Sources of data included classroom observations, one-on-one interviews, and written lesson plans. Data generation occurred over a three-month span of time. Data were analyzed using constant-comparative methods. A theory grounded in the data found four perceived influences on teachers' instructional decisions around planning and practice for technology integration: curriculum and district expectations; professional development; teaching practices; and internal and external factors. These four influences work together, with curriculum and district expectations being the central influence. The findings from this study have implications for educational leaders around their decisions for technology acquisitions, use expectations and design of technology-focused professional development.
