A busca do conhecimento para melhoria da assistência de enfermagem nos serviços de saúde faz-se rotineiramente e a adoção de novas tecnologias educacionais vem colaborar, de forma relevante, para educação permanente dos profissionais. Inúmeros assuntos pertinentes ao cuidado podem ser aprendidos e discutidos em ambientes virtuais, como, por exemplo, os eventos adversos. O presente estudo teve como objetivo desenvolver um ambiente virtual de aprendizagem (AVA) sobre gerenciamento em eventos adversos para educação permanente de enfermeiros, abordando as temáticas: úlcera por pressão, erros de medicação, flebite, queda e perda de sonda nasogastroenteral. O referencial pedagógico foi fundamentado nos estudos de Gagné (1980) que considera que o processo de aprendizagem é baseado na teoria de processamento de informação e constitui-se em oito fases (fase de motivação, de apreensão, de aquisição, de retenção, de rememoração, de generalização, de desempenho e de feedback). A metodologia, uma pesquisa aplicada, utilizou o Modelo de desenvolvimento de programas de Instrução Auxiliada pelo Computador (Computer Assisted Instruction - CAI) proposto por Price (1991), composto de três estágios: 1. planejamento inicial; 2. planejamento e desenvolvimento do conteúdo instrucional; 3. avaliação e revisão. No estágio 1 foi caracterizado o público alvo, escolhido o tema abordado, bem como definidos os objetivos educacionais, os recursos disponíveis, o design instrucional e as técnicas de modelagem. O desenvolvimento do conteúdo (estágio 2) foi realizado em Módulos, estes constituídos das seguintes estruturas: Identificação do Módulo, Objetivos de Aprendizagem, Conteúdos, Exercícios, Referências e Textos de Apoio. A avaliação técnica e revisão do conteúdo inserido no AVA desenvolvido (estágio 3) será realizado por especialistas da área de informática e enfermagem em estudo futuro. O AVA foi desenvolvido na linguagem HTML (Hyper Text Makep Language) utilizando o programa Microsoft Office Word 2003®. Os exercícios de avaliação inseridos em cada módulo foram criados pela autora deste estudo com a utilização do programa Hot Potatoes versão 6.0 para Windows. Conclui-se que a metodologia adotada na construção do AVA foi adequada para o alcance do objetivo proposto. Como metas futuras, a autora desse estudo avaliará o produto desenvolvido e verificará a possibilidade de seu uso nos serviços de enfermagem, contribuindo com a educação permanente dos enfermeiros. O AVA sobre gerenciamento em eventos adversos nos serviços de enfermagem está disponível para acesso no endereço eletrônico: <http://www.eerp.usp.br/nepien/eventosadversos>. / The search for knowledge to improve nursing care in health services occurs on a routinely basis and the adoption of new educational technologies collaborates, in a relevant way, for professionals\' permanent education. Countless subjects pertaining to care can be learned and discussed in virtual environments, such as adverse events. The present study aimed to develop a virtual learning environment (VLE) on management in adverse events for nurses\' permanent education, addressing the themes: pressure ulcer, medication errors, phlebitis, fall and loss of nasogastroenteral feeding. The pedagogical framework was grounded in Gagné\'s (1980) studies, which considers that the learning process is based on the theory of information processing and consists of eight phases (phase of motivation, apprehension, acquisition, retention, remembering, generalization, performance and feedback). This applied research used the Model of development of Computer Assisted Instruction (CAI) programs proposed by Price (1991), consisting of three stages: 1. initial planning; 2. planning and development of instruction content; 3. assessment and review. At stage 1, target public was characterized, theme approached was chosen, and the educational objects, available resources, instructional design and modeling techniques were defined. The content development (stage 2) was carried out in Modules, comprised of the following structures: Identification of the Module, Learning objectives, Contents, Exercises, References and Support Texts. The technical assessment and review of the content inserted in the developed virtual learning environment (stage 3) will be carried out by informatics and nursing experts in a future study. The VLE was developed in HTML (Hypertext Makeup Language) using the program Microsoft Office Word 2003®. The evaluation exercises inserted in each module were created by the study author using the program Hot Potatoes version 6.0 for Windows. It is concluded that the methodology used in the construction of the VLE was appropriate for achieving the proposed objectives. As future aims, the author will assess the developed product and verify the possibility of using it in nursing services, contributing for nurses\' permanent education. The VLE on management in adverse events in nursing services is available at the URL: <http://www.eerp.usp.br/nepien/eventosadversos>.

Aplicativos educacionais podem promover diversos benefícios a professores e alunos, desde a redução de tarefas repetitivas à realização de atividades impossíveis com o uso de apenas lousa e papel. Módulos de Aprendizagem Interativa (iMA) são uma família de aplicativos educacionais que fornecem atividades interativas integradas a Sistemas de Gerenciamento de Cursos. O desenvolvimento de iMA, similarmente ao de outros sistemas criados em contexto de projetos acadêmicos, enfrenta problemas relacionados a manutenção e evolução de software, que afetam suas contribuições à sociedade. Isso é provocado principalmente pela degradação do código com o tempo e dos métodos ad-hoc utilizados, sem sistematização do processo ou procedimentos explícitos para prevenção desses problemas. Com o objetivo de aprimorar esse processo, esta dissertação apresenta uma Linha de Produto de Software (LPS) criada para o desenvolver iMA. O método usado para criá-la envolveu análise do domínio, formado pelos iMA existentes, a elaboração de um modelo de sistema para definir as responsabilidades das características obrigatórias, variantes e opcionais aos aplicativos, e a implementação de um arcabouço de aplicação. Assim, essa LPS consiste nesse arcabouço e seus manuais de funcionamento interno, utilização e evolução, promovendo reúso de código, arquitetura e processo. A avaliação deste trabalho foi conduzida com uma prova de conceito e um estudo de caso. A prova de conceito descreve o desenvolvimento de um novo iMA, chamado iTangran, apresentando a factibilidade da utilização da LPS para essa tarefa. O estudo de caso investigou com maior profundidade o impacto da LPS sobre a criação da nova versão de um aplicativo existente, chamado iVProg. Os resultados obtidos mostram que o oferecimento de um processo e uma arquitetura que guiam as tarefas do programador de iMA teve grande influência na sua percepção de produtividade e satisfação, além de contribuírem para a qualidade do código criado e sua documentação, fatores essenciais para a prevenção dos problemas de desenvolvimento enfrentados atualmente. / Educational software provide many benefits for teachers and students, from reducing repetitive tasks to offering assignments impossible with the use of only blackboard and paper. Interactive Learning Modules (iLM) are a family of educational systems which offer interactive assignments integrated with Learning Management Systems. The development of iLM, similarly to other software created in context of academic projects, faces issues related to software maintenance and evolution, which hinder their contributions to society. This is mainly caused by code degradation with time and to ad-hoc methods used, without a systematic process and explicit considerations to prevent these problems. With the goal of improving this process, this work presents a Software Product Line (SPL) for the development of iLM. The method used to create this SPL involved an analysis of the domain, which are the existing iLM, the creation of a system model in order to define the responsibilities of mandatory, variant and optional features among systems, and the implementation of an application framework. Therefore, the SPL consists of this framework and its manuals for internal operation, utilization and evolution, providing code, architecture and process reuse. Contributions of this work were evaluated by a proof of concept and a study case. The proof of concept describes the development of a new iLM called iTangran, presenting the possibility of using the SPL for this task. The study case investigated more deeply the SPL impact on the refactoring process of an existing iLM, iVProg. Results show that a guide and an architecture for the tasks undertaken by programmers have a significant influence on the perceived productivity and their satisfaction while working, also contributing to code and documentation quality, which are essential factors to prevent development problems such as those faced nowadays.

The problem of this study was that, with the impact of new media and delivery systems, principals and librarians must respond to copyright issues in order to remain informed about the copyright law and the legal use of media. The purpose of this study was to gather and evaluate educator response to issues related to copyright. The study was conducted with a sample of regionally accredited secondary schools in the following states: Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia. A total of 1008 questionnaires were mailed to the principal and the librarian of the 504 schools of the sample. The data of the study were provided by 546 (54%) questionnaires. The first twenty items of the questionnaire provided the variables used to organize, test, and report the data. The second part of the questionnaire was a multiple choice copyright test used to determine the copyright knowledge of the respondent. The t test was used to test the mean copyright test scores of educator groups for significant differences. Groups were defined by professional position, years of experience, involvement or no involvement in job related litigation, and law class or workshop participation since the enactment of the 1976 Copyright Law. Chi-square was used to test the frequencies of reported exposure to the 1976 Copyright Law between professional groups, experience groups, and law class or workshop participation groups. Seven null hypotheses were tested at the.05 level. The mean copyright test score of the librarian group was significantly higher than the mean score of the principal group. The mean test score of the law class participation group was significantly higher than the mean test score of the non-participation group. Responses of exposure to the 1976 Copyright Law provided a five category hierarchy. There was no significant difference in the exposure reported by the principal and librarian groups. The difference of exposure reported by the law class participation group and the non-participation group was significant. Fourteen research questions, which comprised the periphery of the study, were reported. The findings of the study provided the basis for the conclusions and recommendations.

A dramatic expansion of distance learning through the use of interactive television (ITV) is allowing colleges and universities to offer students potentially unlimited access to educational and training opportunities. While the expanding information age beckons us to consider mechanisms for using communication technologies for the benefit of meeting the needs of learners in a variety of locations, the question may be raised--Is ITV an effective medium of instruction? This study examined the effectiveness of using an interactive television system to broadcast developmental algebra classes at East Tennessee State University. The purpose of this study was to determine if there were differences in math achievement of students taught in an ITV class setting with the instructor present (host site), students receiving instruction via television at an off-campus location (remote site), and students taught in a traditional classroom setting. This study also examined student attitudes toward enrolling in future ITV courses. Results showed no significant differences in math achievement among the three groups. There were also no differences in student attitudes toward enrolling in future ITV courses when comparing the host site with the remote site. Students in both television settings had positive attitudes toward future ITV course participation. The results of this study show that in developmental algebra students at the distance learning sites are learning as well as those students in the traditional classrooms. Thus, it was concluded that interactive television should be considered as an adequate method of providing developmental algebra instruction beyond the campus.

In the study, the population of educators in 21st Century Classrooms across the State of Tennessee was surveyed to determine teachers' satisfaction with 21st Century program implementation and associated changes in instructional practices. During fall 1998, six hundred of the 4,800 21st century classroom teachers were surveyed using the Technology Use Questionnaire. Three hundred two completed surveys were returned. Frequency rates and percentages were calculated for each of the 33 questions and the 8 demographic items. The questions were grouped into 7 subscales: Administration, Teacher Training, Implementation, Integration, Use on the Job, Use at Home and Instructional Change. Correlation analysis determined that at the.05 alpha level there were significant relationships between 5 subscales (Administration, Teacher Training, Implementation of the Technology Plan, Integration, and Use on the Job) and Instructional Change. Conversely, there was no significant relationship between the demographic data and instructional change. In general, teachers were unsatisfied with the implementation of the Master Plan for the 21st Century program and had made only moderate instructional changes. The correlation data supported previous research citing teacher training, use on the job, inclusion in future planning, administrative support as impacting instructional change.

Decision making is an inherent part of everyday work and learning processes. Superior decision outcomes can be achieved by structuring decision processes, encouraging domain experts to work collaborative1y, providing visualization ofdecisions as they develop, and providing decision makers with time and flexibility to better understand problems and to project outcomes. Evaluation of distributed synchronous virtual teamwork environments has eluded researchers. The theoretical foundation of this study was Adaptive Structuration Theory (AST) enhanced by a distributed cognition framework. Discourse analysis was used to explore ways to evaluate effectiveness of newly-formed time-constrained self-directed virtual teams using computer-mediated communication (CMC) to solve ill-defined problems. Measures of work process performance were percentages of meeting time devoted to Situation Assessment, Resource Coordination, Idea Generation, and Model Building. Ten measures of work outcome for each of six teams were taken to assess change in decision model quality over time. The data informing this study were obtained during an elective computer science course. The author's course design focused on human-computer interaction (HCI) aspects of use, design, and deployment of computer-supported collaborative work (CSCW) and computer-supported collaborative learning (CSCL) systems. Participants were randomly assigned to teams that remained intact throughout the semester. Teams assumed various roles during policy and software-design scenarios. Networked TeamEC decision-modeling software enabled team problem solving. NetMeeting provided connectivity, application sharing, and text chat for intra-team communication to simulate distributed virtual meetings. Discourse analysis revealed process performance patterns and development of shared mental models ofproblem solutions. The outcome variable (Model Score) improved over time for all teams, but degree of improvement varied greatly among teams. Qualitative analysis of group process variables indicated variance was due to how well teams understood scenario-role requirements and managed available resources. Time usage by process variable was analyzed to measure critical resource use to discover "best practice" guidelines for distributed synchronous teamwork. A Naturalistic Decision Making (NDM) approach extended collaborative experiential learning to complex applied knowledge domains in order to improve problem solving and critical thinking skills. Constructivist learner-centered course design facilitated a clear task focus enabling participants to learn new work practices applicable to classroom and workplace.

This study expands on the current literature base that investigates the use of voice recognition software (VRS) as a compensatory strategy for written language difficulties often experienced by postsecondary education students receiving services under the category of learning disabled. The current literature base is limited to one study (Higgins & Raskind, 1995) which found that subjects' writing samples, completed with VRS, had higher holistic scores than the samples completed with a transcriber, and without assistance. While these findings are positive many questions remain unanswered. The research conducted in this dissertation investigated three such questions. The questions and corresponding findings follow. 1. After being trained on VRS will persons, in postsecondary education, receiving services under the category of learning disabled, continue to use it to complete their academic course work? Will they further use the software for purposes other than academic study? Two individuals continued to use the software. One of these two used the software for multiple purposes. 2. Does the ongoing use of VRS, by postsecondary education students receiving services under the category of learning disabled, improve their written performance when assessed with Fry's Readability Graph? Two subjects each submitted three writing samples: one completed without the use of VRS and two completed using VRS. One subject's grade level equivalency went from 4.5 (sample completed without using VRS) to 6.5 (samples completed using VRS). There was no change in the grade level equivalency of the writing samples for the second subject. 3. What are the contributing variables that influence the continued use, or non-use, of VRS by postsecondary education students receiving services under the category of learning disabled? Numerous variables emerged from the data including: time, access to a personal computer, ease of use, personal issues, use of standard English, the specific limitations associated with a persons disability, whether or not the subjects had other compensatory strategies in place, and the acquisition of the skills necessary to use the software. The findings contribute to the field by providing a framework from which to assess who mayor may not benefit from the use of VRS.
