The purpose of this paper is to study the process of audio information in an online education course at the Federal University of Alagoas (UFAL), which is a federal public university in Brazil. The study was conducted in the second school term of 2010 and in the first school term of 2011, in the Bachelor degree Pedagogy course online education model. Case study was chosen as the method to examine the use of web radio and audio webcasting podcasts in online education, with the UFAL Moodle virtual learning environment. The hypothetical-deductive method was adopted for reasoning and the quali-quantitative method was used for data collection. These data are shown in the reports written during the two research phases exploratory and experimental. The experimental phase was conducted with the subject Knowledge and Methods for Teaching Natural Sciences 1 , which had 176 enrolled students, from different UFAL units of several cities in Alagoas Maceió, Maragogi, Santana do Ipanema and Olho d´Água das Flores. As a reception study, students who composed the audience of live transmissions and the recording of live transmissions could communicate in a synchronous and in an asynchronous way with the tutor. Such communications were mainly conducted in forums. Then the audio information was evaluated with an online questionnaire. The main objective was to find how the formats could be associated with the Moodle Virtual Learning Environment, with the Pedagogical Project and with the online education course. The results were satisfactory in terms of acceptance of both formats by the audience group, which shows that the associations proposed are possible. However, such associations need to be part of a plan that includes forms of evaluating audio information. The results also point to the need for better infrastructure regarding technical support for faculty members including tutors in order to create, produce and transmit didactic materials. Moreover, we found that wideband services need improvement in the State. Our main conclusion is that the formats studied should be created, produced and/or selected by the course for educational purposes. They should also present characteristics of radio phonic language, including sound and web graphic interface, aligned with the education design of the course, especially in the Moodle virtual learning environment. It is also necessary to identify the target audience, their level of digital fluency, and their conditions for accessing computers and the Internet, in order to promote the interaction with the most adequate technologies and tools for audio webcasting. This study is based on theories by Moore and Kearsley (2008), Peters (2004), Haandel (2009), Martín-Barbero (2009), Jacks and Escosteguy (2005), Reyzábal (1999), Machado (2009), Silva (2006; 2010), among others. / O presente trabalho tem por finalidade tratar do processo de transmissão de mídia sonora na educação a distância on-line da Universidade Federal de Alagoas, integrante da Universidade Aberta do Brasil, nos períodos letivos de 2010.2 e 2011.1, no curso de Pedagogia Licenciatura, na modalidade a distância. O estudo de caso foi escolhido como método de abordagem do objeto de estudo e teve por objetivo investigar a utilização dos formatos web rádio e podcasts do webcasting sonoro na educação a distância, no ambiente virtual de aprendizagem Moodle UFAL. Adotou-se o raciocínio do método hipotético-dedutivo e foi utilizado o método quali-quantitativo durante a coleta de dados, os quais são apresentados nos relatos das fases da pesquisa. Esta foi desenvolvida em duas fases: a exploratória e a experimental, tendo como campo de atuação experimental a disciplina Saberes e Metodologias do Ensino de Ciência Naturais 1, a qual possuía 176 estudantes matriculados, vinculados aos polos das cidades alagoanas de Maceió, Maragogi, Santana do Ipanema e Olho d´Água das Flores. Como estudo de recepção, os estudantes que formaram a audiência das transmissões ao vivo e das gravações dessas transmissões puderam se comunicar de forma síncrona e assíncrona com o professor, por meio principalmente de fóruns, e posteriormente avaliaram a mídia sonora por meio de questionário on-line. A questão norteadora foi: como esses formatos poderiam ser associados ao ambiente Virtual de Aprendizagem Moodle, ao Projeto Pedagógico e à dinâmica da modalidade a distância do curso? Os resultados foram satisfatórios em termos de aceitação dos dois formatos pelo grupo-escuta, mostrando que as associações da questão norteadora são possíveis, mas precisam fazer parte de um planejamento que inclua também as formas de avaliação da mídia sonora, além de apontarem para a necessidade de maior infraestrutura do curso em termos de suporte técnico para o corpo docente, incluindo os tutores, no sentido de criação, produção e transmissão de material didático e também para a necessidade de melhoria na condição de banda larga do Estado. A conclusão principal é a de que esses formatos devem: ser criados, produzidos e/ou selecionados pelo curso para fins educativos; apresentar características da linguagem radiofônica, incluindo a montagem sonora, e interface webgráfica aliada ao design educacional do curso, especialmente no ambiente virtual de aprendizagem Moodle; e identificar seu público-alvo, incluindo seu nível de fluência digital, além das condições de acesso a computadores e internet, de forma a promover o diálogo interativo pelas tecnologias e ferramentas mais adequadas ao uso do webcasting sonoro.

Distance Education (DE) is a teaching modality capable of providing professional formation for people with limited access to university education. For this end, a set of computational tools is required in assisting the teaching and learning process (PEREIRA et al., 2006a). Moreover, some common obstacles for DE are the issues of identifying possible advisors for those students in the process of writing monographs and work overload. This has become an important issue for researches, placing their emphasis on the idea of working the interests of students, teachers and education managers. For such, this work used a quali-quantitative approach, in a way that data were collected in a Distance Learning Environment (DLE) and also by the application of a structured questionnaire to potential advisors. As such, this work has the objective of proposing a Computational Model of Social Combination that helps the DE Manager in the process of advisors planning for monograph works. This paper presents three computational tools developed by using genetic algorithms. These tools were applied according to the context of the DE undergraduate course of Information Systems offered by the Federal University of Alagoas and the Open University of Brazil. The results show that the proposed computational model can be used to help DE Managers to reduce the cases of students’ and advisors’ profiles incompatibility, as well as to reduce docent work overload. / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A Educação a Distância (EAD) é uma modalidade de ensino capaz de viabilizar a formação de profissionais com dificuldades de acesso à formação universitária. Para tanto, esta modalidade necessita dispor de um conjunto de ferramentas computacionais que viabilizem o processo de ensino aprendizagem (PEREIRA et al., 2006a). A identificação de possíveis orientadores e a sobrecarga de trabalho são algumas das dificuldades existentes neste processo. Pesquisas nesta área investem na idéia de trabalhar os interesses de alunos, professores e gestores da educação. Para tanto, esta pesquisa utilizou uma abordagem quali-quantitativa, de maneira que os dados foram coletados em um Ambiente Virtual de Aprendizagem (AVA), bem como através da aplicação de um questionário estruturado aos orientadores em potencial. Desta forma, este trabalho tem o objetivo de propor um Modelo Computacional de Combinação Social que auxilia o Gestor de EAD no processo de planejamento de orientadores de trabalhos monográficos. São apresentadas três ferramentas computacionais, desenvolvidas por meio de algoritmos genéticos, que foram aplicadas no âmbito do Curso de Bacharelado em Sistemas de Informação a Distância, ofertado pela Universidade Federal de Alagoas e Universidade Aberta do Brasil. Os resultados obtidos apontam que o modelo computacional proposto pode ser utilizado para auxiliar os gestores de EAD na redução dos casos de incompatibilidades de perfis de alunos e orientadores, bem como na redução da sobrecarga de trabalho dos docentes.

Text in English / This study explores and describes the perceptions of student nurses regarding professional nurses as role models in the clinical learning environment. An exploratory-descriptive qualitative approach was followed. The population for this study was the final year students in the programme: Bridging course for enrolled nurses leading to registration as a general nurse. Nonprobability, quota sampling was done. The study was conducted at two Gauteng campuses of a private nursing education institution. Two “World Café” conversations were conducted where after data saturation was achieved. The three major themes that emerged were professionalism of the professional nurse, the need for student support and the teaching and learning environment. From the students’ feedback it was evident that professional nurses should be aware of the important role they play in the professional and personal development of students. Professional nurses as role models should portray the professional behaviours and attitudes required by the profession. Students have a vision of how they expect to be when they qualify as professional nurses. Recommendations from this study relate to the three themes identified and clearly indicate that students have a realistic expectation of and a need for visible role models in the clinical learning environment. / Health Studies / M.A. (Health Studies)

This study deals with the way school principals, educators and learners manage learner behaviour inside the classrooms, as well as in the entire school for the effective and uninterrupted realisation of teaching and learning activities. A qualitative approach was used in this study. The research findings were based on observations, the analysis of documents, as well as the main and sub-categories that were formulated from the interview data gathered at the selected schools. The research confirmed what is already known on learner discipline and discipline problems. In the dissertation more attention is given to factors that contribute to misbehaviour, the impact of misbehaviour on the culture of learning and teaching, and how learner behaviour should be managed in the classrooms and in the schools in general. Furthermore, effective measures of managing learner behaviour are explained and a comprehensive school-wide model of preventing and remediating learner misbehaviour is also provided. / M. Ed.

Significant changes have taken place in higher education over dte past ten years. Learners are more liberated and want to be acknowledged as individuals with differences, and not expected to adapt their individual characteristics to fit in with the specific environment of the learning situation. A new emphasis is placed upon creating and sustaining learning environments that accommodate Ieamer needs and dte process of effective learning. Learners' individual needs include their need to learn how to learn and an acceptance of their individual differences as expressed in learning styles. Active Ieamer participation in dte learning process is necessary for effective learning to take place. Only dten can the desired outcome be reached. For a Ieamer to actively participate in the learning process, the Ieamer must know how to learn, and how to function as an independent Ieamer. To reach these goals, sound knowledge of individual differences in learning st;ytes is necessary. The impact of individual differences on education and the way they affect educational practice, future learning and academic achievement places the emphasis even more strongly on constant awareness, updatlng or change, improvement and development of the educational environment. The educator, as one of the role players in the educational environment, is the facilitator of learning, and should be empowered with a strong knowledge base regarding individual differences among both learners and educators, thus becoming more innovative and creative. Qualitative non-empirical research was undertaken. The aim of this research was to analyse and explore the concept learning style as well as to promote learning style awareness through assessment of learning st;ytes, and to provide an organised frame of reference to guide the learning process and provide for systematic education. Based on insight and knowledge gained through Inductive and deductive reasoning, The Learning Style Assessment Tool and a model for learning style promotion in higher education were constructed. The instrument enables learners and educators to assess their own learning st;ytes and identify their learning characteristics and preferences. The model can serve as a basis for acknowledging and accommodating learning styles in higher education. The desired outcome of this research is effective learning and quality education. / Health Studes / D. Litt. et Phil. (Advanced Nursing Sciences)

The study investigated the perceptions of student nurses and supervisors with regard to the block system used in the general nurse diploma programme in Zimbabwe. Their perceptions were elicited so that the researcher could identify the positive and negative aspects of the blook system which respectively promote and inhibit or obstruct the teaching and learning of student nurses. The study was conducted at the Harare, Parirenyatwa, Mpilo and United Bulawayo Schools of Nursing and in Mashonaland East province. A cross·sectional descriptive survey research design was used to obtain accurate information about the block system. Data was collected from nurse teachers, clinical teachers and sisters in charge of wards/units by means of structured interviews and from community health nurses and student nurses by means of self-administered questionnaires. The following positive aspects of study blocks were identified: the availability of time for student nurses to acquire knowledge, skills and attitudes without fear of hurting patients, the availability and willingness of nurse teachers to teach, the attendance of study blocks as groups and straight off duties. During clinical area placements, the integration of theory and practice took place, and there were opportunities for student nurses to apply the knowledge and skills they learnt during study blocks and to work as members of health teams. The negative aspects of the study blocks that were identified included too much theory content taught in each study block, inadequate demonstrations, a shortage of nurse teachers, no periods for individual study, a theory-practice gap and the too-frequent use of the formal lecture teaching method. The negative aspects of the clinical area placements included the inadequate teaching/supervision of student nurses, excessive night duties for student nurses, a shortage of qualified staff: clinical allocation of student nurses not based on study block content, inadequate clinical teaching by nurse teachers, and unplanned clinical teaching. Most clinical teaching was performed by peers and the most junior professional nurses. / Health Studies / D.Litt. et Phil. (Advanced Nursing Sciences)

The purpose of the study was to assess Challenges of and Opportunities for Implementing the School improvement Programme in the Public secondary Schools of Iluababor administrative zone in Ethiopia. In the study a mixed research methodology was employed, specifically the sequential explanatory designs with a high priority on the quantitative and the sequential exploratory design and with less priority on the qualitative data. Out of 24 secondary schools, 12 secondary schools were selected by random sampling from six geographically clustered secondary schools. In the study (out of a total of 540 sample populations, 287 research participants were selected by random sampling/lottery method, 220 male and 67 female) were participated to fill the questionnaires. For interviews from six clusters (12 school principals, 12 district education experts, six secondary supervisors and four zone education experts) were selected by purposeful sampling to participate in the interviews sessions. Whereas, for focus group discussions ( 21 parent teachers‟ association (PTA) members; and 21 members of student councils) were as well selected by the purposeful sampling technique from three clustered geographical locations of the schools respectively. The collected data was analysed using statistical programme for social science software (SPSS) version 21. To analyse the data from questionnaires, descriptive statistical analysis like frequencies, percentile, mean values, and standard deviation were used. While, qualitative data generated from interviews, focus group discussions and document analysis were transcribed, coded and interpreted thematically. The findings indicated that with regards to the quantitative data analysis, the performances of the school improvement programme aggregate of the four domains summary of the mean values and standard deviations 287 (Mean = 2.82; SD = 0.74) showed that the indicators of practices among the school improvement programme domains were low in performance. The qualitative results as well confirmed the quantitative results. In this case, the mean value was above average and the standard deviation value was more tightly clustered around the mean. This means that the results were concurrent of each other and thus reliable. The findings revealed that, even though secondary schools put a lot of effort towards averting the challenges in school improvement, it could hardly bear fruit due to insufficient supplies of inputs and processes. This resulted in the school improvement programme performances lagging behind the set goals and targets. Additionally, the findings indicated that the major challenges in the implementation of the school improvement programme in secondary schools (9-10) were: weak collaboration among stakeholders, lack of capacity building, inefficient administrative services, limited commitment of school leadership and school governing bodies, poor school leadership and management, passive and inactive involvement of parents and local community, and, in the academic affairs, students were not successful in terms of attendance and the achievement of learners. Based on the findings, it is recommended that school principals, teachers, administrative staff, students, parents and local school communities be well equipped with basic knowledge and skills on the school improvement programme. This could help in fostering critical thinking and the problem solving capacity of the learners. In addition, school principals and the school governing bodies have to apply the recommended strategies in the study so as to alleviate the challenges in (grades 9-10) secondary schools. Above and beyond, the study suggested that in order to get better learners achievement, a strong team spirit should be established among school principals, secondary school supervisors, teachers, students, parents and local communities, and by expanding capacity building networks within the coming five years. Consequently, the schools management teams and other stakeholders of secondary schools (9-10) have to plan for continuous training and orientation on the nature, practice and significance of school improvement programme implementation. / Educational Leadership and Management / D.

A tese apresenta uma contribuição à área da pesquisa educacional, para auxiliar na identificação de perfis cognitivos, utilizando o referencial teórico das Ciências Cognitivas e a instrumentação das Neurociências. O projeto elaborado para atender os objetivos desta tese compreendeu o desenvolvimento de metodologia experimental, apoiada pela técnica estatística de Projetos de Experimentos, juntamente com instrumentos neurocientíficos (uso de eletroencefalografia com técnica ERP – Event Related Potential), para a observação, quantificação e interpretação de evidências neuronais – sinais de eletroencefalografia - relacionadas ao processo cognitivo humano. Buscou, em particular, evidências relacionadas às diferentes demandas de energia despendida na realização de atividades espaciais (identificação, percepção ou atenção espacial de objetos virtuais), com base em instrumentos teóricos e tecnológicos das Neurociências, das Ciências Cognitivas e da Psicologia Cognitiva, para uso na área da pesquisa educacional, visando contribuir para identificação de diferentes perfis de estudantes em diferentes áreas do conhecimento. Na investigação experimental, o objetivo foi buscar indicadores (quantificação de energia alocada em atividade cerebral, medida de tempo de resposta ao estímulo, maior magnitude na faixa de freqüência do ritmo elétrico cerebral, evocados no experimento) dos sinais cerebrais que estejam sincronizados com o exercício proposto e que possam subsidiar a hipótese de que há diferenças significativas entre estudantes de áreas científicas e tecnológicas e estudantes de áreas humanas e sociais, no quesito habilidades espaciais. A proposta contextualiza e fundamenta experimentos com um grupo de alunos voluntários dos cursos de graduação, selecionados para a pesquisa, classificados por idade e sexo e avaliados e selecionados por diagnóstico psicológico indicativo da provável área de aptidão/habilidade cognitiva. O desenvolvimento da proposta investigativa, que visou atender os objetivos relacionados e pertinentes ao processo, foi possível devido a esforços de pesquisadores e cientistas das diferentes áreas de conhecimento, que colaboraram na modelagem do experimento realizado no Laboratório de Biosinais da Universidade de Caxias do Sul, no Campus Universitário da Região dos Vinhedos, junto ao Curso de Engenharia Elétrica. Como parte do processo metodológico experimental está compreendido o desenvolvimento do instrumento de medição: equipamento de eletroencefalografia (EEG) utilizando o sistema de aquisição e conversão de sinal analógico-digital da National Instruments e também, o equipamento conhecido como Gaiola de Faraday, que serviu para a realização das coletas de sinais elétricos cerebrais de baixa freqüência e amplitude, minimizando a presença de ruídos eletromagnéticos interferentes significativamente no sinal coletado. Os dados (sinais elétricos cerebrais) coletados durante o experimento que evocou raciocínio lógico espacial dos participantes foram modelados matematicamente por Fourier e interpretados por análise estatística – UNIVARIATE (análise de variância) e comparados aos resultados obtidos pelos instrumentos de apoio utilizados como forma de validar o processo investigativo: questionário verbal ao final do experimento e teste psicológico - subteste BPR5 – RE. Todos os dados coletados também foram armazenados com o propósito de permitir futura realização de outras simulações, com diferentes métodos de acesso aos conteúdos. Entende-se que os resultados obtidos nesse experimento possam colaborar com a Informática aplicada à Educação no planejamento, desenvolvimento e uso de objetos virtuais em ambientes destinados a mediar à aprendizagem, de acordo com necessidades específicas de cada público-alvo. Nesse sentido, os resultados dessa investigação podem prover dados ou características como medidas indicadoras de esforços cognitivos associados a perfis diferenciados, no caso das áreas de conhecimento, que envolvam processos de raciocínio espacial. O entendimento sobre o esforço manifestado pelo aluno durante o experimento foi interpretado como uma possível medida de um dos itens relacionados ao perfil cognitivo, à luz das Ciências Cognitivas (GARDNER, 1994, 2001), (STERNBERG, 2000), (PINKER, 1998). / The thesis is to contribute for the area of educational research in order to aid on the identification of cognitive profiles, using theoretical references from cognitive sciences and instrumentation from neurosciences. The project designed to meet the objectives of the thesis included the development of experimental methodology, supported by the statistical technique for Experiment Projects, along with neuroscientific instruments (use of electroencephalography with the ERP technique – Event Related Potential), for the observation, quantification, and interpretation of neuronal evidences – electroencephalography signals – related to the human cognitive process. It particularly searched for evidences related to different demands of energy spent to perform spatial activities (identification, perception, or spatial attention of virtual objects), based on theoretical and technological instruments of Neurosciences, Cognitive Sciences and Cognitive Psychology, used in the field of educational research, with the aim to contribute for the identification of different profiles of students in different areas of knowledge. In the experimental investigation, the purpose was to look for indicators (quantification of energy allocated in brain activity, measuring response time to the stimulus, larger magnitude in the frequency band of the brain electrical rhythm, evoked on the experiment) of the brain signals that would be synchronized with the exercise proposed and that could subsidize the hypothesis that there are significant differences between students from scientific and technological fields and students from humanistic and social fields, regarding spatial abilities. The proposal contextualizes and fundaments experiments with a group of volunteer students from the undergraduate programs, selected for the research, classified by age and gender, and evaluated and selected according to a psychological diagnostic indicating a probable area of cognitive ability / aptitude. The development of the investigative proposal that intended to meet the objectives mentioned was possible thanks to efforts of a group of researchers and scientists from different fields of knowledge, pertinent to the process, who collaborated on the modeling of the experiment, carried out at the Biosignal Laboratory of the University of Caxias do Sul, at the University Campus of Região dos Vinhedos, in its Electrical Engineering Program. The development of the measuring instrument was part of the experimental methodological process: the equipment for electroencephalography (EEG) using the system acquisition and conversion of analog to digital signal (manufacturer: National Instruments) and also the equipment known as Faraday’s Cage, which served to the collections of electrical brain signals of low frequency and amplitude, minimizing the presence of electromagnetic noises interfering significantly on the signal collected.The data collected (brain electrical signals) during the experiment that evoked logical spatial reasoning by the participants were mathematically modeled by Fourier and interpreted by statistical analysis – UNIVARIATE (variance analysis) and compared to results obtained by support instruments used as a way of validating the investigative process: a verbal questionnaire at the end of the experiment and a psychological test – subtest BPR5 – RE. All data collected were also saved with the purpose of making it possible to carry out other simulations in the future, with different access methods to the contents. It is understood that the results obtained with this experiment collaborate Informatics applied to Education on planning, developing, and using virtual objects in environments destined to mediate learning according to specific needs of each target public. In that sense, the results of this investigation may provide data or characteristics as measures indicating cognitive efforts associated to differentiated profiles, which are in this case the knowledge fields involving spatial reasoning processes. Understanding the effort manifested by the student during the experiment was interpreted as a possible measure for one of the items related to the cognitive profile, the light of Cognitive Sciences (GARDNER, 1994, 2001), (STERNBERG, 2000), (PINKER, 1998).

The environment, implemented in Moodle platform of Distance Education is supported by dynamic geometric viewers idealized by GeoGebra. It approaches points in the Cartesian plane, the distance between two points, midpoint, barycentric, angular coefficient, alignment condition of three points, equation of a line, forms of equation of straight lines, relative positions of two straight lines and perpendicular straight lines. This virtual learning environment contains activities in two units implemented using the tools of Moodle, including WEB page, Lesson, Forum and Questionnaire, always founded in the learning theories of Piaget, Vygotsky and Ausubel. All of this seeks a construction of knowledge through the interactivity with the approached topics, in an autonomous way and respecting the self-paced learner. It also aims the understanding of the concepts in a practical and dynamic way, not limited to the dissemination of the information in a pre-defined static way. In the dynamic of such application, the virtual theoretical activities are followed by practical issues incorporating the content studied, with frequent assessments in the form of discussion forums, quizzes and tests with questions randomly selected from a database of the virtual environment. Despite the difficulties, the first unit can be successfully completed verifying a significant learning of the use of dynamic geometry simulators, with the students showing greater interest and focus on the approached issues. / Este trabalho apresenta a construção de um ambiente virtual de aprendizagem sobre tópicos de geometria analítica plana e sua aplicação em turmas do ensino médio público da cidade de Barra Bonita, interior de São Paulo. O ambiente, implementado na plataforma Moodle de Educação a Distância, é apoiado em visualizadores geométricos dinâmicos idealizados no GeoGebra. Aborda pontos no plano cartesiano, distância entre dois pontos, ponto médio, baricentro, coeficiente angular, condição de alinhamento de três pontos, equação de uma reta, formas de equação de retas, posições relativas de duas retas e retas perpendiculares. Contém atividades em duas unidades implementadas através das ferramentas do Moodle, entre elas Página WEB, Lição, Fórum e Questionário, sempre buscando embasamento nas teorias de aprendizagem de Piaget, Vygotsky e Ausubel. O ambiente busca a construção do conhecimento através da interatividade com os temas abordados, de forma autônoma e respeitando o ritmo do aluno aprendiz, objetivando sempre a compreensão dos conceitos de forma prática e dinâmica, sem se restringir à disseminação de informações de forma estática pré-definida. Na dinâmica de aplicação as atividades virtuais teóricas são seguidas de questões práticas envolvendo o conteúdo estudado, com avaliações constantes na forma de fóruns de discussão, simulados e provinhas com perguntas aleatoriamente escolhidas de um banco de questões auto-corrigíveis do ambiente. Apesar das dificuldades encontradas, a primeira unidade pode ser concluída com sucesso verificando uma aprendizagem significativa a partir da utilização dos simuladores de geometria dinâmica, com os alunos mostrando maior interesse e concentração nos assuntos abordados.
