Title: Algorithmic Science News: support platform for science journalism Abstract: The Algorithmic Science News (ASN) platform is a new tool created by a multidisciplinary team that emerged from the need to reinscribe the role of science news in today's media space. The platform aims not only to increase the number of scientific news available to publishers, but also to reduce the effort associated with more time-consuming tasks such as collecting data and analyzing scientific articles and thereby facilitating the entire news production process. The ASN platform includes a set of features designed to support the journalist's standard procedure in writing contexts, allowing the use of documents in open access scientific repositories. The development of algorithms working on these repositories followed the purpose of facilitating the access and exploration of these collections and allowing the media to use them as an information source. In this project we developed tools of reading and interpretation, writing and semantic suggestion. With regard to reading and interpretation, ASN helps on finding specialists related to the scientific article, summarizes the most determinant parts, namely the introduction, objectives, methodologies and results, present definitions of technical terms, and suggest projects related to the topic. With regard to the writing part, the platform allows to write notes related to parts of the article and have access to phrases suggestions. The use of a beta version of this platform in writing contexts will allow the realization of the extent to which the automation of tasks associated with journalistic production can help the media in transition to digital, as well as to contribute to a greater efficiency in the tasks associated with science journalism, allowing a greater massification and quality in the production of scientific news in the current media landscape. Description: A plataforma Algorithmic Science News (ASN) é uma nova ferramenta criada por uma equipa multidisciplinar que surgiu da necessidade de reinscrever o papel das notícias sobre ciência no espaço mediático presente. A plataforma tem como objetivo aumentar o número de notícias científicas disponíveis para os editores e reduzir o esforço associado a tarefas mais demoradas como a recolha de dados e análise de artigos científicos, facilitando todo o processo de produção de notícias. A plataforma ASN agrega um conjunto de funcionalidades destinadas a apoiar o trabalho habitual de um jornalista em contextos redatoriais, permitindo a utilização de documentos em repositórios científicos de acesso aberto. O desenvolvimento de algoritmos que trabalham sobre estes repositórios seguiu o propósito de facilitar o acesso e a exploração destas coleções e permitir que os órgãos de comunicação as utilizem como fonte informativa. Neste projeto desenvolveram-se ferramentas de leitura e interpretação, escrita e sugestão semântica. No que concerne à leitura e interpretação, o ASN permite encontrar especialistas relacionados com o artigo científico, resumir as partes mais determinantes, nomeadamente a introdução, objetivos, metodologias e resultados, apresentar definições de termos técnicos e sugerir projetos relacionados com o tema. No que diz respeito à parte de escrita, a plataforma permite escrever notas relacionadas com partes do artigo e ter acesso a sugestões de frases. A utilização de uma versão beta desta plataforma em contextos redatoriais permitirá perceber até que ponto a automação de tarefas associadas à produção jornalística poderá ajudar os meios de comunicação em transição para o digital, assim como contribuir para uma maior eficiência nas tarefas associadas ao jornalismo de ciência, permitindo uma maior massificação e qualidade na produção de notícias científicas no panorama mediático atual.

Title: Universo Digital de Mário Cesariny Abstract: The incorporation of the Mário Cesariny collection, stimulated Cupertino de Miranda Foundation in finding a way of disclosure, which allows the dissemination of information related to his work, particularly by individuals who, in a direct or indirect way, were important to the Mário Cesariny's legacy. After examining the collection of information, we selected the personalities that are the representative core, but not exhaustive of his universe. The works and documents treated with different framework in physical environment get together in the digital environment making it possible to imagine the connections between them. This way, it was possible to gather in the same digital space, all the strands of Cupertino de Miranda Foundation: museum, library and personal archives. The way the contents were prearranged enables the chronological structure of the documents and the identification of professional and personal relationships of Mário Cesariny. The technical implementation of the portal uses an Open Source solution for managing digital content. Being a web-based solution, we can manage and administer all the content in a web browser, operating system independently. This independence also facilitates portability between systems and the WWW. Description: A incorporação do acervo de Mário Cesariny estimulou a Fundação Cupertino de Miranda na procura de uma forma de divulgação, que permita a difusão de informação ligada à sua obra, particularmente através de individualidades que, de uma forma directa ou indirecta, foram importantes para o legado de Mário Cesariny. Depois de analisado o acervo de Informação, seleccionaram-se as personalidades que são o núcleo representativo, mas não exaustivo do seu Universo. As obras e documentos tratados, com enquadramento distinto no espaço físico, reúnem-se em ambiente digital tornando possível a visualização das ligações existentes entre eles. Desta forma, foi possível reunir no mesmo espaço digital, todas as vertentes de acção da Fundação Cupertino de Miranda: museu, biblioteca e arquivos pessoais. A forma como foram estruturados os conteúdos permite a identificação cronológica e estrutural das relações profissionais e pessoais de Mário Cesariny. A implementação técnica do portal recorre a uma solução Open Source para a gestão de conteúdos digitais. Sendo uma solução baseada em ambientes Web, é possível gerir e administrar todos os conteúdos com um navegador de internet, independente do sistema operativo. Esta independência também facilita a portabilidade entre sistemas e para a WWW.

Title: Using plagiarism detection tools in order to control group work submissions in large courses Abstract: Peer education and teamwork are looked upon as important educational tools due to the massification of higher education programmes. As such, teams frequently produce several deliverables throughout a given course, and these should be properly organized and assessed. As the deliverables submission process often occur in large numbers, any attempt to manage the procedure too tightly is bound to make the evaluators spend a lot of time just checking, controlling and correcting each individual submission; assessing these vast numbers of deliverables, is another problem, which is simply too vast to tackle in this article. Nevertheless, we do use plagiarism detection tools which offer invaluable information to evaluators. These mentioned tools are also used in an unsuspecting way: while allowing the students to submit the deliverables in a loose way, these tools can be used to check, and control any wrongdoing with little effort. This article shows the details of the implementation and the lessons learned. The prototype was tested in a course which has roughly one thousand students enrolled in, and that had effectively produced a course-portfolio of an organized set with all deliverables in an (almost totally) automated manner.

Title: PLACES - A Web Platform for Accessibility Abstract: How many times a person does not understand a video because cannot access its sound? How often persons have wondered about how interesting it would be to have a certain book in audio format, to continue reading while doing other activities? With the exponential growth of digitization of information in contemporary society, it is essential to adopt accessibility policies to technologies and information systems. The provided information should be considered for different users and different usage contexts. The more versatile or flexible the format is, the more useful and effective it can be for everyone. Aiming to contribute to an increasingly universal design, an online platform with tutorials that provide guidelines for creating accessible digital documents formatted in Word, PowerPoint and HTML was implemented. In addition, two experimental tools were provided: one for reading mathematical formulas written in MathML and the other to convert to text and speech simple SVG images, allowing the user to navigate through the description. The challenge is, on one hand, to give users knowledge about tools that already offer resources to create accessibility, and that due to general lack of information are simply just not used; on the other hand, as done in the following chapter on HTML, to review the usefulness of fundamental aspects and some strategies to create and provide information.

Title: Accessibility Course: Training Higher Education academics in the University of Porto Abstract: Universities face new challenges as they have to deal with an increasing number of disabled students attending their curricula. In Portugal, Higher Education Institutions (HEI) are still not prepared, as teaching and non-teaching staff face serious difficulties interpreting accessibility guidelines, and are not aware of their important role for providing accommodations. This paper presents the findings of the first national initiative on a HEI to help implementing an inclusive curriculum. We developed a course on accessibility and observed that staff had little or no training on how to deal with disabled students, although they were willing to learn how to adapt their curricula to this new reality. In conclusion, new courses and workshops on accessibility will have to be developed within the U.Porto to reach a larger and more diverse audience and thus contributing to build a barrier free community where all students can feel included.

Title: New Challenges in the Higher education area: university networks for internationalization and globalization. Abstract: The "A NAME for Health" project, funded by the EDULINK program, is a project that establishes A Network Approach in Medical Education (NAME) for the Pursuit of Quality in Higher Education Institutions (HEIs) and Health Systems. It aims to improve Health Care through an ongoing intervention quality program on Medical Education, at 4 HEIs in Portugal, Angola and Mozambique: Faculty of Medicine of University of Porto (project coordinator), Portugal; Faculty of Medicine of Agostinho Neto University, Luanda, Angola; Faculty of Medicine of Eduardo Mondlane University, Maputo, Mozambique; and Faculty of Health Sciences of Lúrio University, Nampula, Mozambique. São João Hospital, E.P.E. and Calouste Gulbenkian Foundation are associated with this Project. Specifically, this Higher Education project aims at reinforcing the Partner Institutions' ability to improve academic skills and clinical specializations in three priority areas (Paediatrics, Gynaecology & Obstetrics and Infectious Diseases) related with the Millennium Development Goals. The presence of a qualified network for Medical Education helps to elevate the overall level of medical care available to the people of Angola and Mozambique, through academic stimulation. The network's priority is to reinforce the capabilities and the existing strengths of the Higher Education sector, through the creation of a more qualified staff and supporting an efficient development of these HEIs. With these objectives in mind, three types of activities are being developed: structuring, academic and clinical activities. Structuring activities include the establishment of Centers for Medical Education, creation of a Network Technological Platform to the different HEI (e-learning and long-distance learning), and the establishment of Students Support Office; academic activities consist of an analysis of the medical curriculum, its reform, implementation and monitoring, and IT Seminar/Conference; clinical activities comprise the establishment of a mobility program for clinical teachers and physicians. The project's strength and sustainability come from the belief that improvements in the whole Health System will be attained through the improvement of clinical and academic practice. Increasing the Institutions' scientific, pedagogical and clinical levels will enhance the network of Portuguese speaking countries, strengthening the link between Medical Education Healthcare in the African Higher Education Institutions. Sustainability will also be reinforced through the Technological Platform (which will be maintained among the Institutions) since it will enhance the investments that are being done in the partner Universities' information and communication technologies. Curricular reforms and their adaptation to international standards, together with the expected multiplier effects obtained through the clinical mobility program, will also be a way of supporting academic and clinical sustainability after the conclusion of the project. The competence acquisitions in the three priority clinical areas will also have a multiplier effect at the level of knowledge transfer to the other health agents such as nurses and health community agents. Focusing on Medical Education by structuring its organization, will generate involvement of young medical students, which will be the future physicians and clinical teachers (The Project A NAME for Health is supported by EDULINK Program, Contract nr. 9 ACP RPR 118 # 29)

Title: An increasing demand of Basic Biostatistics courses following the Bologna principles: a flexible blended learning approach Abstract: There is a growing demand in Basic Biostatistics courses in new or reformulated curricula degrees according to the Bologna Process. Basic Biostatistics is a fundamental scientific component of biomedical, public health sciences and biological research areas. Both graduate students from biomedical/biological areas or mathematical/bioengineering areas should be trained to have not only the theoretical knowledge in biostatistics but also the verbal and written skills to be effective in a team research environment. The university should be prepared to offer a course in Basic Biostatistics with some flexibility in order to be easily adapted to the different profile of the students. Following the so-called Bologna Process students should be motivated to take part of the learning process and the role of the teacher is more of facilitator and tutor of that learning process. Is based on this new principle that innovation in the training programs in biostatistics is necessary. A Virtual Learning Environment was used and activities such as forums, databases and assignments were implemented. This blended learning experience revealed to have flexibility in its adaptation to the needs of different scientific areas (Aquatic Sciences, Public Health and Mathematics) and degrees (undergraduate, master and doctoral). The success achieved by a student who could only access the on-line environment indicates that an e-learning approach could be possible. The use of assignments with the format of a scientific paper developed the writing skills; forums worked as an excellent tool for sharing information and stimulating communication between students and teacher; and databases stimulated students to research topics of the program and thereby participate in their own learning process. This training program was an opportunity to innovate the teaching and learning methodology of Basic Biostatistics. Students were trained to be able to convert data into information with a balance between knowledge of statistical methodology and training in communication. Students also developed skills and competencies necessary to the knowledge society and professional career. This training program could also be considered in more advanced biostatistics programs, distance learning programs or even other courses, according to the student market in higher education.

Title: Teaching optics with the centennial universal lantern Abstract: A projection apparatus was bought in 1909 by the Physics Cabinet of the Polytechnic Academy (predecessor to the University of Porto's Faculty of Science) in order to present various physics experiments, mostly in the realm of Optics, to a large student audience. A stout and impressive mahogany and brass piece, with a voltaic arc lighting system, it was manufactured by the firm E. Leybold's Nachfölger, based in Chemnitz (Germany), already with a worldwide reputation as a supplier of teaching instruments and equipment to superior schools and universities. It was sold along with an extensive set of accessories, allowing for demonstrations in geometrical optics, spectrum analysis, interferometry, diffraction, polarization and double refraction. Two extra attachments, one for projecting microscopic objects, and the other for the projection of gypsum preparations in polarized light, added to the versatility of this lantern, appropriately dubbed of universal use. Both apparatus and accessories are presently to be found in the collection of the Museum of Science of our University. On studying them, we have come to the conclusion that many classical experiments in Optics may be displayed, without great effort and in an attractive manner. The adaptation to present day usage takes no more than the replacement of the lantern's voltaic arc by a suitable and safer light source. It so happens that a hundred-year old projection apparatus, fitted with a set of purposely designed add-ons, becomes so effective as its modern counterparts. Description: Em 1909 foi adquirido pelo Gabinete de Física da Academia Politécnica (instituição que precedeu a Faculdade de Ciências da Universidade do Porto) um aparelho de projecção universal, para fazer demonstrações de experiências de Física, principalmente no domínio da Óptica, em frente a grandes audiências. Peça imponente de madeira de mogno e latão, com um sistema de iluminação por arco voltaico, foi vendido pela firma E. Leybold's Nachfölger, de Chemnitz (Alemanha), com reputação firmada como fornecedor de instrumentos e equipamentos para ensino em escolas superiores e universidades. Foi acompanhado por um grande conjunto de acessórios, para demonstrações de óptica geométrica, análise espectral, interferometria, difracção, polarização e dupla refracção.Dois acessórios específicos, um para projecção de preparações microscópicas e outro para projecção de diapositivos em gesso sob luz polarizada, aumentam a versatilidade do instrumento, apropriadamente designado de uso universal. O aparelho de projecção e os acessórios encontram-se presentemente na colecção histórica de instrumentos científicos do Museu de Ciência da Universidade. O estudo destes levou-nos a concluir que muitas experiências clássicas podem ser mostradas sem grande esforço e de forma sugestiva. A adaptação à realidade presente requer apenas a substituição do arco voltaico por uma fonte de luz apropriada e mais segura, provando-se assim que um aparelho com cem anos de existência e um conjunto de acessórios desenhados para as diferentes utilizações é tão eficaz como os seus equivalentes modernos.

Title: A utilização de um modelo de blended learning no ensino da Bioestatística ao Mestrado em Saúde Pública Description: A Bioestatística é uma componente científica fundamental da investigação na área das ciências da saúde e, como tal, deve preparar os estudantes quer em termos teóricos quer para a prática da análise estatística. Com o Processo de Bolonha muitas foram as alterações, e a que mais se destacou foi o aparecimento de um novo paradigma que coloca o estudante como o "actor principal" do processo de ensino-aprendizagem. A Universidade do Porto, através do seu Gabinete de Apoio para as Novas Tecnologias na Educação (GATIUP), tem procurado incentivar a utilização das tecnologias de informação e comunicação entre a sua comunidade académica, destacando-se sobretudo o incentivo à introdução de um modelo de blended learning na leccionação das unidades curriculares. Ao fim de alguns anos a leccionar unidades curriculares de Bioestatística, com os cursos homologados no âmbito do Processo de Bolonha, era necessário adaptar os métodos de ensino ao novo paradigma da educação. Assim, por intermédio do GATIUP, estabelece-se o primeiro contacto com o denominado modelo de blended learning. Após algumas reuniões com um dos elementos do GATIUP, começa-se a ponderar a utilização da plataforma de e-learning (Moodle) como instrumento pedagógico de ensino-aprendizagem na unidade curricular de Bioestatística I do Mestrado em Saúde Pública da Universidade do Porto. Após algumas dificuldades iniciais próprias da "adaptação" a este novo ambiente, percebeu-se o potencial que a combinação da componente teórica (presencial), prática (presencial) e do elearning (não presencial) tinha, não só na dinamização da relação/comunicação entre docentes e estudantes, como na melhoria da qualidade dos métodos de avaliação e acompanhamento dos estudantes. No curto período de duração da unidade curricular, em que se recorreu a um modelo de blended learning, procurou-se "explorar" um conjunto de recursos e actividades (fóruns de discussão, base de dados e trabalhos on-line) disponibilizadas por esse ambiente de aprendizagem virtual, que constituíssem uma mais valia para os estudantes e docentes.

Title: The University of Porto : Information Management and Appraisal Abstract: The University of Porto presents a complex organisational macro-system which generates an equally complex information system, involving both scientific, technical and cultural knowledge and educational and administrative activities, supported by several technological platforms. The complexity of this universe requires to an integrated approach regarding the information produced and its management, moving towards an information management model which has its epistemological foundations in the scientific area of Information Science. The main purpose of this paper is to present the University of Porto's perspective regarding an integrated information management model directed at the challenges and needs of the Information Era and to share the experiences carried out under a new theoretical approach that assumes Appraisal as a methodological operation inserted within the technical pole of the Quadripolar Research Method in Information Science. The theoretical approach was studied/applied in a research project whose main goal was to create a framework, as objective as possible, to determine through information analysis the final destination of the information produced and accumulated in the course of activities undertaken by the University of Porto and its information subsystems (colleges, research institutes and other organic and functional sectors). In 2002, the appraisal results, obtained under this new approach, received approval from the body that, in Portugal, coordinates archival policies, the Directorate-General of Archives under the Ministry of Culture. The theoretical basis adopted by the University of Porto, quite different from the model traditionally advocated based on the dichotomy

Title: E-Portfolios and assessment: a case study for civil engineering Abstract: The University of Porto implemented a project for the use of e-portfolios in its academic community. The main idea of this project was to use the e-portfolio as an assessment tool of the student learning journey and also to show the importance of this reflective work for their academic and professional life. One of the examples that decided to use this methodology was the discipline of Construction Management, from the Faculty of Engineering. The students were in their fifth year of the master in Civil Engineering. The testing was done in 2006 and 2007. The conditions that led to this option were the experience obtained in the use of an e-learning platform for five years (WebCT), the fact that the contents of the classes have a close connection with the professional activities and the symbiosis between the educational, professional and curriculum components of the exercise. The assessment was graded based on the result of elaboration of the e-portfolio dedicated to present what the students had learned in the course: There was no imposed structure but a core index was suggested. The development of the e-portfolios was made by the students with the technical support of the Office of Support for New Technologies in Education of University of Porto (GATIUP). The learning objectives presented at the beginning of the course were also analyzed by each student in the e-portfolio at the end of the learning. The results were important to assess the learning objectives and to adapt some of the teaching arrangements to accommodate the criticisms and behaviors presented by the students. For the teacher the main result of these experiences was that digital portfolios are an excellent way to assess knowledge, competences and skills acquired by the students. A parallel benefit was the improvement on using web pages as communication tools.

Title: Erasmus Intensive Learning Course at the Faculty of Arts of Porto University: a Blended Learning Experience Abstract: This study presents an Erasmus Intensive Language Course in Portuguese for beginners and intermediate level students, held at the Faculty of Arts of the University of Porto, and financed by the Grundtvig Lifelong Learning Programme Erasmus. The main goals of the course are to prepare Erasmus students for their mobility by developing their language skills in Portuguese, such as reading, writing, listening, and speaking; rising the students' ability to communicate appropriately and accurately in spoken and written Portuguese, encouraging students to communicate in Portuguese; enabling students to discover and learn Portuguese by and for themselves; and providing students with Portuguese cultural awareness. The students are chosen according to the criteria established by Grundtvig, namely (i) priority to students whose L1 is quite different from Portuguese; (ii) different countries; (iii) several studying areas; and (iv) the creation of a multinational, multicultural and multilingual context. Having in mind the above mentioned goals and participants, a blended-learning (b-learning) course was designed as following: 2 weeks of online training using the Moodle platform, for a total of 20 hours; 3 or 4 weeks of in-class training, with online support, for a total of 76 hours; 4 afternoons for the cultural component, for a total of 12 hours, and 72 hours of individual study. This paper discusses in detail the course's technical and content framework, the advantages of a blearning approach to teach foreign languages, specially considering there will be an initial e-learning contact with Portuguese, whether to introduce the students to Portuguese sounds and most basic structures before their arrival in Portugal, or by allowing the students who had already had formal contact with Portuguese Language to revise their knowledge and assess their level of proficiency. This approach has proved to be a better choice compared to other intensive courses of the same level and similar background students with only in-class teaching.
