- Student teachers' perceptions of the Internet: Motivation, influences, and usePublication . Almeida, Conceição; Morais, Carlos; Miranda, Luísa; Viseu, Floriano; Martinho, HelenaThe Internet's rapid growth and diffusion, both worldwide and in our country, as well as its importance for teacher education, made us feel the need to reflect on how our student teachers integrate themselves in such quite novel environmental conditions and teaching communities. This paper reports on one specific Portuguese university’s student teachers’ Internet usage during their teaching practice and what reasons motivated them to do so. It also looks into student teachers' perceptions about Internet discussion and usage by other teachers in their schools and, in particular, in their own disciplinary groups. The data was collected using a questionnaire which was anonymously answered by 189 of the entire 360-student teacher 2000/2001 population from all 9 different preservice programs.
- Poster - A fishing system of a system to search for educational content for the semantic webPublication . Gonçalves, Vitor; Carrapatoso, EuricoA primeira geração da Internet preocupou-se com a implementação da infra-estrutura tecnológica e dos serviços respectivos (o conteúdo educativo era disponibilizado através de páginas estáticas hipertexto e a interacção professor/aluno era estabelecida essencialmente através de correio electrónico, não havendo monitorização do percurso do aluno), a segunda incidiu na construção de aplicações Web (o conteúdo educativo passou também a ser disponibilizado através de páginas dinâmicas geradas a partir de base de dados; as tecnologias de comunicação - email, fóruns, chats, áudio e vídeo-conferência - integraram-se com as tecnologias de informação Web formando sistemas de e-Learning que incluem capacidades de acompanhamento dos alunos e de gestão dos conteúdos de aprendizagem) e, actualmente, a terceira avança rumo a uma Web mais inteligente – a Web Semântica (almejando num futuro próximo que os computadores, ou melhor, os agentes de software, sejam verdadeiros parceiros do processo de aprendizagem). Genericamente, o e-Learning preocupa-se, por um lado, com a comunicação entre o professor e o aluno (interacção social e intra-pessoal) e, por outro, com os conteúdos do curso (interacção com os recursos de aprendizagem). É esta última componente que interessa no âmbito deste poster. A Sociedade da Informação e do Conhecimento em que vivemos exige-nos uma contínua e rápida actualização dos conhecimentos para que possamos adaptar-nos e reagir às constantes mudanças profissionais e sociais. A interiorização do conceito de educação ao longo da vida tem vindo a impulsionar novas formas de auto-aprendizagem, tais como: a aprendizagem através de conteúdos Web dispersos localizados por motores de busca e a aprendizagem através de conteúdos disponibilizados por sistemas de e-Learning. No entanto, o crescimento da Web tornou cada vez mais problemática a descoberta e a recuperação desses objectos de aprendizagem. Neste sentido, sugere-se, ao nível dos recursos, o uso de metadados e ontologias OWL para a pesquisa de objectos de aprendizagem dispersos e, ao nível da representação do domínio de conhecimento, o uso de mapas de conceitos, descritos através da tecnologia XTM (XML Topic Maps), para apoiar a recuperação de objectos de aprendizagem organizados em cursos de e-Learning e, consequente, geração de planos de formação personalizados. Assim, esta proposta sugere uma arquitectura para um sistema de pesquisa de conteúdos de aprendizagem baseado em tecnologias de e-Learning, tecnologias da Web Semântica e tecnologias de Agentes (Voyager ORB Java).
- Collaborative environments work: a case study of teacher trainingPublication . Meirinhos, Manuel; Osório, AntónioIn recent years, many research projects related to cooperative and collaborative learning, as well as to learning communities based on these practices, have appeared. Numerous authors have recognised the innovative potential of collaborative networked learning, thus allowing for the growth of research in the field of collaboration connected with education and distance learning. In this paper, through a case study in the context of teacher training, we intend to show that collaborative environments actually work.
- Pedagogical approaches for online environmentsPublication . Miranda, Luísa; Morais, Carlos; Dias, PauloAt a time of profound changes in both learning conceptions and the construction of knowledge representations and in their application in real-life and professional situations, there is a huge need to deepen the processes that help us understand collaborative learning in online environments. These environments, due to their advantages, are powerful means for the development of the flexibility of representations and their suitability to practice contexts. The success of online collaborative activities depends on several aspects, among which can be mentioned their planning and monitoring of learning, bearing in mind the necessity to create a feeling of community and connection among the students seeking to engage in the joint definition of learning objectives. Therefore, the online environments are a way of expanding the boundaries of human communication and sustaining complex processes of interaction through the networks that make up the virtual classroom. Apart from admitting the importance of online environments, which goes beyond the development of the themes of online learning and online collaboration, we shall also present some results about student perceptions when exposed to the development of learning activities in online environments, based on research carried out within a doctoral thesis done in the University of Minho. Collaboration and the ways it develops in new learning communities is one of the main aspects of the above-mentioned study as well as a fundamental means for student learning because in this way they can understand questions, develop arguments and share meanings and conclusions.
- The microorganisms in the Portuguese national curriculum and primary school text booksPublication . Mafra, Paulo; Lima, NelsonThe main aim of the present work is the content analysis of the Portuguese National Curriculum and the Primary School textbooks where microorganisms are concerned. The content analysis through categories created a priori were used as methodology. In all analysed documents the topic microorganisms did not emerge in a clear way. However, several indirect themes related to microorganisms were found in the National Curriculum and textbooks of the Environment Study issue. These themes can be explored with pupils through experimental activities. The Science Education in primary schools can be introduced with proposals of activities involving microorganisms and contributing to a better understanding of the children’s world.
- Continuous training in Mathematics: influence on the professional knowledge of elementary school teachersPublication .

- Information technology for grandparents and grandchildrenPublication . Gonçalves, Vitor; Patrício, Maria RaquelIn a global and technology society, new technologies often represent an exclusion factor for the elderly population, unlike what happens with the digital natives. By contrast, young people today are fluent in the language of the new digital technologies. Information Technologies and Communication (ICT) can be key elements to bring different generations and promote the strengthening of family ties and sharing experiences. In this context, TINA project (Information Technology for Grandparents and Grandchildren) whose main aim is to promote family cohesion between grandchildren and grandparents through the ICT including through the Internet. It presents a pilot experiment involving two groups of grandparents and grandchildren in the district of Bragança, Portugal, in 2010. Apart from living promoted by the ICT, participants were trained in basic ICT skills and participated in workshops on the use of communication/interaction technologies between grandparents and grandchildren. The project culminated with the completion of a contest based on webquests before the Grandparents day.
- The effect of depth on drag during the gliding phase in swimmingPublication . Marinho, D.A.; Ribeiro, João; Mantripragada, Narendra; Machado, Leandro; Vilas-Boas, João Paulo; Fernandes, Ricardo J.; Barbosa, Tiago M.; Rouboa, Abel; Silva, A.J.The gliding phase following a swimming start or turn is an important component of the overall swimming performance. PURPOSE: To analyse the effect of depth on hydrodynamic drag force during the underwater gliding, using computational fluid dynamics. METHODS: A three-dimensional domain was created to simulate the fluid flow around a swimmer model, representing the geometry of part of a lane in a swimming pool. The water depth of this domain was 1.50 m with a 3.0 m width and 11.0 m length. Computational fluid dynamics methodology was used to perform numerical simulations in the created domain which was divided into a number of mesh cells. The k-epsilon turbulent model was applied to the flow around a three-dimensional model of a male adult swimmer in a prone gliding position with the arms extended at the front. General moving object model was used to simulating the body as the displacing object. During the gliding, the swimmer model’s middle line was placed at three different water depths: at 0.20 m (just under the surface), at 0.75 m (middle of the pool), and at 1.30 m (bottom of the pool). The drag coefficient and the hydrodynamic drag force were computed using a steady velocity of 2.50 m/s for the different depths run for 3 s in each case. RESULTS: The drag coefficient was 0.37, 0.34 and 0.30 and the drag force was 141.40 N, 128.10 N and 115.30 N when gliding at a water depth of 0.20 m, 0.75 m and 1.30 m, respectively, at the time of 2 s when the swimmer was approximately at the middle of the computational pool. CONCLUSIONS: The hydrodynamic drag values for the gliding decreased with the increase in depth. This decrease of drag values with depth can be due to the reduction of the wave drag effect, which has an important contribution to total drag near the water surface. Reducing the drag experienced by swimmers during the glide off the wall can decrease start and turn times and unnecessary energy loss. Hence, these results suggested that gliding at 0.75 m under the water surface or deeper seemed to be an optimal gliding depth for minimizing drag and improve swimming performance
- Is front crawl swimming performance affected by hydrodynamic drag in young swimmers?Publication . Silva, A.J.; Marques, Mário C.; Garrido, Nuno D.; Barbosa, Tiago M.; Costa, M.J.; Louro, Hugo; Reis, Victor M.; Marinho, D.A.Swimming performance is affected by several factors including the hydrodynamic drag. Hydrodynamic drag is the force that a swimmer has to overcome in order to maintain his movement through water and is highly dependent on swimming technique. PURPOSE: To analyse in young swimmers the relationship between hydrodynamic drag and the front crawl performance. METHODS: 25 young swimmers (11 females and 14 males) participated in this study. Their mean (standard deviation) age, body mass, height and best swimming performance in 100 m front crawl was 12.08 (0.76) years, 43.08 (7.60) kg, 1.52 (0.08) m and, 75.11 (9.57) s, respectively
- Reflection on pratice: content and depthPublication . Martins, Cristina; Santos, LeonorThis text is based upon an ongoing investigation with the main goal of studying the professional development of primary school teachers, specifically the ability to reflect, within a continuous training program. This study follows a methodological approach of a qualitative type, comprising case study, with recourse to interviews, participant observation and documental analysis. A first analysis of the written reflection of one of the participants, included in the reflection portfolio, points, in terms of content, towards less spreading of the themes approached, the ones considered the most significant being subsequently extracted and correlated. A greater depth in the reflection is also noted, with the teacher having concern to justify her statements, present a critical analysis of her role and rethink her practice.
