Educational application of remote experimentation for mobile devices

In this article the authors describe the application development RExMobile and the importance of remote experimentation via mobile devices, especially smartphones simple, beyond the space provided for this application in education. The article deals the creation, software and hardware that provide an interactive and dynamic way to attract more students to use these experiments remote, serving as support to teachers to science teaching from its initial series. The ease and availability of smartphones, even these students of basic education, permits the reach of new users and in different places. Thus, the practice of remote experimentation in mobile devices enables new spaces for access and interaction. Are used for developing software free or low cost, HTML5 and jQuery Mobile framework, that enable the creation of pages compatible with different mobile operating systems such as iOS, Android, Windows Phone, some Symbian, among others. Also are demonstrated patterns layouts that allow greater accessibility.

TRAILER – e-Portfolio for collecting and recognizing informal learning process and outcomes

Informal learning is becoming more and more important: Nowadays people learn more this way, through the Internet, than in schools or normal trainings. But they don’t get any certificateswhich attest this fact. So they can't show the employer or teacher etc. that they have learned something. TRAILER project aim is to solve this problem by developing a special tool for managing of all competences and skills acquired through informal learning experiences. Both from the perspective of the user and the perspective of an institution or a company. We’ll present the IT tool to show how people can make their informal learning outcomes visible. TRAILER helps users to gather all information about process and outcomes of their informal learning. Users can share this with friends, colleagues or their employees, teachers and so on. They can create an interactive e-portfolio which can be attached to their CV, cover letter or Knowledge Management system etc. After the presentation of the tool we will discuss possible areas and fields to use this tool. Also we would like to discuss all possible use of the tool by the participants and another needs in this area. Moreover we want to discuss other problems in informal learning process, ways to solve the problems and discuss other ideas of different IT tools which could help in informal learning process. During the discussion we’ll use an interactive respond system which can be used on mobile devices: it makes possible for participants to share their opinions individually before knowing another persons' opinion.

Student performance analysis under different moodle course designs

This work extends a recent comparative study covering four different courses lectured at the Polytechnic of Porto - School of Engineering, in respect to the usage of a particular Learning Management System, i.e. Moodle, and its impact on students' results. A fifth course, which includes a number of resources especially supporting laboratory classes, is now added to the analysis. This particular course includes a number of remote experiments, made available through VISIR (Virtual Instrument Systems in Reality) and directly accessible through links included in the Moodle course page. We have analyzed the students' behavior in following these links and in effectively running experiments in VISIR (and also using other lab related resources, in Moodle). This data have been correlated with students' classifications in the lab component and in the exam, each one weighting 50% of their final marks. We aimed to compare students' performance in a richly Moodle-supported environment (with lab component) and in a poorly Moodle-supported environment (with only theoretical component). This question followed from conclusions drawn in the above referred comparative study, where it was shown that even though a positive correlation factor existed between the number of Moodle accesses and the final exam grade obtained by each student, its explanation behind was not straightforward, as the quality of the resources was preponderant over its quantity.

Desenvolvimento de recursos educativos em dispositivos móveis - RealHiBook

Nos últimos anos têm existido bastantes pesquisas e um grande investimento quer na área da educação à distância quer ao nível das tecnologias móveis. A dada altura percebeu-se que cada vez mais poderiam ser utilizados dispositivos móveis no contexto da educação e de que estes já seriam capazes de responder às exigências necessárias para que fosse possível criar ou melhorar cenários com recursos educativos. Este trabalho tem como objetivo propor um modelo que facilite a aprendizagem em dispositivos móveis. Nesse sentido, decidiu-se que seria uma mais-valia adicionar a este projeto, a utilização da Realidade Aumentada como potenciador de melhorias no processo de aprendizagem. A Realidade Aumentada, a par do que acontece com a educação à distância e com as tecnologias móveis, é uma área alvo de constantes investigações e inovação. Apresenta como principal capacidade a interação do utilizador com vários modelos virtuais incluídos numa cena real. Esta capacidade proporciona experiências que podem contribuir para o aumento da motivação e da perceção por parte dos alunos. A forma como o utilizador interage com as aplicações móveis é vista com extrema importância, principalmente na área da educação. Aliar uma boa interação à utilização da Realidade Aumentada, é parte integrante deste trabalho. Foram estudados exemplos de interações e formas como o utilizador vive a experiência durante a utilização de aplicações que partilham o mesmo tipo de tecnologias utilizadas neste projeto. O objetivo final foca-se na criação de uma aplicação, capaz de fornecer uma experiência enriquecedora no âmbito do ensino, ligado ao tema história e que consiga fundamentar a criação de um modelo que facilite a aprendizagem utilizando plataformas móveis. Os objetivos são corroborados por um conjunto de testes efetuados à aplicação e pelos resultados obtidos através de um questionário feito a um grupo de pessoas que testaram o protótipo.

Tecnologias multimédia no apoio ao ensino aprendizagem de suporte básico de vida

A sociedade moderna encontra-se numa evolução progressiva e vertiginosa nomeadamente no que respeita às novas tecnologias. Independentemente da área de conhecimento, é de senso comum que cada vez mais é necessária uma formação sólida, sendo fundamental a preparação e a consolidação das futuras gerações na utilização das novas tecnologias. As plataformas de e-learning são hoje em dia uma realidade mais que afirmada e com aplicação em todos os setores de atividade. Na área da saúde, e mais concretamente no que diz respeito ao tema de Suporte Básico de Vida (SBV), foi-nos possível verificar que a maioria das pessoas revela falta de conhecimentos sobre o tema e, não obstante existirem cursos sobre este tema, a disponibilidade para a sua frequência nem sempre é possível pela distância, falta de tempo e disponibilidade para a sua frequência, bem como pelos custos envolvidos. O presente estudo pretende contribuir para uma análise e investigação sobre o potencial de utilização das novas Tecnologias Multimédia, aplicando-as ao ensino concreto de primeiros socorros e especialmente de Suporte Básico de Vida, num recurso educativo digital com o formato de Objeto de Aprendizagem. Para o efeito, será construído um Objeto de Aprendizagem temático, focalizando o tema de SBV. O repositório MERLOT foi utilizado como meio de distribuição global, no sentido de aferir o potencial e facilidade de distribuição e catalogação com metadados. Foi ainda colocado on-line o “SBVOA” (Objeto de Aprendizagem desenvolvido no presente estudo), numa página criada apenas para o efeito. Esta dissertação apresenta o estudo desenvolvido para investigação do potencial de aprendizagem proporcionado pelo Objeto de Aprendizagem desenvolvido, validando se pode ser uma alternativa interativa de educação em SBV, contribuindo deste modo para a diminuição de eventuais perdas de vida.

Aplicação de advergames no contexto do Ensino Superior

As novas tecnologias, e a Internet em particular, criaram novas formas de transmissão de informação para o público e alteraram a forma como as pessoas comunicam. Isto abriu portas a novas formas de publicidade e ao aparecimento de um novo género de jogos, os advergames, aproveitando o facto dos jogos online contarem já com milhões de jogadores a nível mundial, um número que continua em constante crescimento. O conceito é relativamente recente mas apresenta resultados bastante positivos, com muitos especialistas a defender que os advergames são o futuro da publicidade, em grande parte devido aos custos inferiores e ao tempo de exposição do produto, quando comparado com os métodos mais tradicionais de publicidade. Os Jogos Sérios e, em especial, os advergames são o tema principal desta tese, com uma análise detalhada das suas vantagens e desvantagens, origens e oportunidade de desenvolvimento no futuro. São também analisados alguns casos de advergames de sucesso. A componente prática da tese tem como objetivo a criação de um advergame com o propósito principal de auxiliar os novos alunos do ISEP no seu processo de integração. O jogo consiste num formato de labirinto em duas dimensões, com objetivos que consistem na captura de certos objetos e entrega dos mesmos em pontos de destino pré-definidos, sempre dentro de um tempo limite e evitando outros perigos e obstáculos. Os resultados obtidos com a aplicação deste jogo demonstram que a transmissão de informação é bastante eficaz junto do seu público-alvo, devido em parte à abordagem mais dinâmica e interativa que um advergame tem com os seus utilizadores. A simplicidade da interface e facilidade de utilização proporcionada pelo jogo permitem uma exposição alargada da mensagem a passar, aumentando a motivação do jogador para se manter em contacto com o mesmo. Isto apresenta perspetivas bastante otimistas para o futuro da utilização de advergames no meio Universitário.

A new horizon for online teaching and learning

The Polytechnic Institute of Oporto (IPP), which has a solid history of online education and innovation through the use of technology, has been particularly interested and focused on Massive Open Online Courses (MOOC) developments. The aim of this paper is to present the whole process from initial discussions to completion of the “Mathematics Without Limits” MOOC Project that exists in IPP and also to contribute for a change in the way as teaching and learning Mathematics is seen and practiced nowadays. In 2013, IPP developed its own platform, which gave us the opportunity to explore new educational techniques as a pedagogical resource as well as to enhance students’ motivation, through a set of interactive materials at their disposal, totally adapted to their needs. Students lack of motivation is mainly justified by their weak Math preparation, poor consolidated basis on the subject and different backgrounds of the students. To tackle this issue and based on our Math online courses teaching experience, we decided to create short duration MOOC, expecting to aid retention of students and also to reverse the path of students giving up on Math by giving them a friendly way of managing their own learning commitment. We also think that this MOOC will be a good approach to level out some math skills among freshmen.

Personalisation of Networked Video

Following targeted advertising and product placement, TV and online media needs more personalised methods of engaging viewers by integrating advertising and informational messages into playout content, whether real-time broadcast or on-demand. Future advertising solutions need adaptivity to individuals or on-line groups to respond to the commercial requirements of clients and agencies.

Personalised placement in networked video

Personalised video can be achieved by inserting objects into a video play-out according to the viewer's profile. Content which has been authored and produced for general broadcast can take on additional commercial service features when personalised either for individual viewers or for groups of viewers participating in entertainment, training, gaming or informational activities. Although several scenarios and use-cases can be envisaged, we are focussed on the application of personalised product placement. Targeted advertising and product placement are currently garnering intense interest in the commercial networked media industries. Personalisation of product placement is a relevant and timely service for next generation online marketing and advertising and for many other revenue generating interactive services. This paper discusses the acquisition and insertion of media objects into a TV video play-out stream where the objects are determined by the profile of the viewer. The technology is based on MPEG-4 standards using object based video and MPEG-7 for metadata. No proprietary technology or protocol is proposed. To trade the objects into the video play-out, a Software-as-a-Service brokerage platform based on intelligent agent technology is adopted. Agencies, libraries and service providers are represented in a commercial negotiation to facilitate the contractual selection and usage of objects to be inserted into the video play-out.

Joint effects of salinity and the antidepressant sertraline on the estuarine decapod Carcinus maenas

Concurrent exposure of estuarine organisms to man-made and natural stressors has become a common occurrence. Numerous interactions of multiple stressors causing synergistic or antagonistic effects have been described. However, limited information is available on combined effects of emerging pharmaceuticals and natural stressors. This study investigated the joint effects of the antidepressant sertraline and salinity on Carcinus maenas. To improve knowledge about interactive effects and potential vulnerability,experiments were performed with organisms from two estuaries with differing histories of exposure to environmental contamination. Biomarkers related to mode of action of sertraline were employed to assess effects of environmentally realistic concentrations of sertraline at two salinity levels. Synergism and antagonism were identified for biomarkers of cholinergic neurotransmission, energy production,anti-oxidant defences and oxidative damage. Different interactions were found for the two study sites highlighting the need to account for differences in tolerance of local ecological receptors in risk evaluations.
