Promoção da literacia matemática no pré-escolar com o apoio da tecnologia educativa

O projeto “Promoção da Literacia Matemática no Pré-Escolar com o apoio da Tecnologia Educativa” traduz a investigação realizada junto de um grupo de crianças do pré-escolar com 3/4 anos e dos seus pais e encarregados de educação, numa instituição educacional privada, em Lisboa. Objetiva-se a promoção de competências matemáticas na educação pré-escolar, seguindo as orientações científicas nacionais e internacionais, de que a matemática é a ciência do padrões. O segundo grande objetivo do projeto visa promover a colaboração dos pais na educação pré-escolar dos seus filhos. O Programme for International Student Assessment [PISA] refere que todo e qualquer indíviduo deve ter a possibilidade de adquirir uma literacia matemática crítica ao longo da sua vida, por forma a aplicá-la na sua vida pessoal, social e profissional. A Literacia Matemática vem contrariar a associação da matemática à manipulação arcaica dos símbolos matemáticos sem conexão e relação entre si. Mais do que dominar um conteúdo, a Literacia Matemática Crítica traduz-se nas competências que um aluno desenvolve na resolução de problemas, no relacionamento de conceitos e conteúdos, na identificação de estratégias de resolução ou na comunicação com os demais numa linguagem matemática escrita/oral. O segundo ponto do projeto objetiva promover e estimular a colaboração dos pais e encarregados de educação com a escola. Pretende-se que ambas as entidades mediadoras da construção de conhecimeto da criança possam comunicar e estabelecer estratégias de ação relativamente à educação da criança, como parceiros educativos. Os recursos tecnológicos evoluem de dia pra dia e estão acessíveis aos pais, filhos e escolas, pelo que podemos aspirar que estes possam contribuir para a parceria educativa. Em ambiente pré-escolar, pretende-se desenvolver atividades que visem objetivos matemáticos em simultâneo com a exploração do computador, periféricos e de um software desconhecido. Escolhemos um software de edição de imagem, estabelecendo um paralelo entre a pintura virtual e a pintura tradicional. Metodologicamente, a investigação assenta num estudo qualitativo, tendencialmente investigação-ação, combinando e articulando técnicas de pesquisa como a observação participante, as conversas informais com a educadora, os elementos da direção, os pais/encarregados de educação, e a análise documental. As planificações das atividades visaram a concretização dos objetivos propostos para a intervenção. No processo cíclico de investigação-ação foram identificadas dificuldades nas crianças, relativamente à matemática e ao software, pelo que, a cada ciclo, foram definidas estratégias que visassem a construção de processos de desenvolvimento na criança. As estratégias educativas assentaram essencialmente na abordagem matemática dos padrões, na planificação cuidada das atividades distintas para crianças e para pais, na utilização de recursos tecnológicos, como sejam o computador, um software de edição de imagem, o email e a webpage da escola.

An extratropical cyclone database: A tool for illustrating cyclone structure and evolution characteristics

Extratropical cyclone lifecycles have been studied extensively with the aim of understanding the dynamical mechanisms involved in their development. Previous work has often been based on subjective analysis of individual case studies. Such case studies have contributed heavily to the generation of conceptual models of extratropical cyclones that provide a framework for understanding the dynamical evolution of cyclones. These conceptual models are widely used in educational meteorology courses throughout the world to illustrate the basic structure and evolution of extratropical cyclones. This article presents a database of extratropical cyclone composites which highlight the average structure and evolution of 20 years of extratropical cyclones, as opposed to individual case studies. The composite fields are achieved by combining a database containing cyclone tracks from the ERA-Interim reanalysis (1989-2009, 6 hourly) with the full 3D ERA-Interim reanalysis fields. Vertical and horizontal composites of cyclone structure for cyclones generated in the Atlantic and Pacific regions identifying features such as the relative positions of cold, warm and occluded fronts and their associated wind and cloud patterns are shown. In addition the evolution of cyclonic flows such as the warm and cold conveyor belts and dry intrusion are illustrated. A webpage containing an archive of the composited data is freely available for educational purposes.

Gamers preferenser för användargränssnitt på en spelrelaterad webbplats

Användargränssnittsdesign är en stor del av en webbsidas intryck och förändras snabbt i takt med teknologins utveckling och trender. Men det gäller även att locka rätt användare. Hur lockar en webbsida till sig rätt målgrupp? Målet med rapporten var att analysera målgruppen gamers utifrån hur de upplever det grafiska användargränssnittet på en spelrelaterad webbsida. Rapporten behandlar även översiktitligt om aktuella trender för webbdesign tilltalar gamers. Undersökningen utfördes i två delar. I den första delen undersöktes 20 av de största spelrelaterade webbsidornas användargränssnitt. Under del två genomfördes en enkät och intervjuer med målgruppen gamers. I både enkäten och intervjuerna fick respondenterna ta ställning till olika mockups av en fiktiv webbsida. Det var stor skillnad på vad gamers ansåg vara tilltalande jämfört med hur de analyserade webbsidorna såg ut. Exempelvis var endast 25 % av de analyserade webbsidorna mörka medan 71,9 % av respondenterna föredrog en mörk layout.

Televisão universitária do RN (TVU): contribuição para a democratização da informação e a difusão do conhecimento científico produzido pela universidade

In this thesis we propose to investigate the contribution that the Universitary Television from Rio Grande do Norte state, Brazil (TVU RN), offers to democratization of information and diffusion of the scientific knowledge produced by the Federal University of Rio Grande do Norte (UFRN) from the perception of their own students. We adopt the basic assumption in wich the TVU RN needs to be connected with the scope of the current UFRN policy, since plays an important role regarding democratization and social inclusion policies in UFRN. We support the thesis that TVU UFRN offers important information for those who are part of academic culture (COULON, 1995a; 1995b, CHARLOT, 2000; BOURDIEU, 2007, 2005, 1997, 1996, 1975), as well as for society in wich it is inserted, since it contributes to the dissemination of scientific knowledge and relevant information about the university. We consider TVU RN a Public Sphere (HABERMAS, 2002; 2003a, 2003b; 2003c; 1999; 1989) conducive to discussion of issues involving higher education. Researches on Universitary Television are recent and some studies on it advanced in the way to define it and present it as a means of dissemination of scientific knowledge (ROCHA, 2006; COUTINHO, 2006; CALLIGARO, 2007; AIRES, 1999; PORCELLO, 2002; PRIOLLI, 2003, 2008, 2009; MAGALHÃES, 2002, 2008; RAMALHO, 2008; 2010; CARVALHO, 2006). For our investigation we chose the combination of quantitative and qualitative methods, both equally valid and accepted by many authors (FLICK, 2009; BAUER; GASKELL, 2002; RICHARDSON, 1999; LAVILLE; DIONNE, 1999). We developed a questionnaire initially with objective questions ending up with open questions of free text. The questionnaire was developed and hosted from a tool of Google Docs and the link to the webpage containing those questionnaires was sent by e-mail by the Permanent Commission of Vestibular of UFRN, COMPERVE, for all university students who were with their registration (status) active in the COMPERVE registers of the second half of 2010. The analysis of this material was performed using the techniques of content analysis and, within this mode was chosen thematic analysis considered appropriate for both qualitative and quantitative research (BARDIN, 2004; MINAYO, 2002). The investigation found that although most students consider that the TVU RN contributes to the democratization of information and dissemination of scientific knowledge produced in university, and moreover to arouse the interest of the academic community, still has not yet become an object of interest of the entire academy. Therefore, the research highlights the relevance and abrangency of further studies on the TVU RN due to the strategic role it plays in this new reality of public universities in the country. In addition, we suggest to the UFRN managers that they put TVU within the hall of discussions in order to receive the so much needed investment for any university organ

THE EFFECTS OF WEB-BASED TECHNOLOGICAL RESOURCES IN A RURAL SCIENCE CLASSROOM

Today’s technology is evolving at an exponential rate. Everyday technology is finding more inroads into our education system. This study seeks to determine if having access to technology, including iPad tablets and a teacher's physical science webpage resources (videos, PowerPoint® presentations, and audio podcasts), assists ninth grade high school students in attaining greater comprehension and improved scientific literacy. Comprehension of the science concepts was measured by comparing current student pretest and post test scores on a teacher-written assessment. The current student post test scores were compared with prior classes’ (2010-2011 and 2009-2010) to determine if there was a difference in outcomes between the technology interventions and traditional instruction. Students entered responses to a technology survey that measured intervention usage and their perception of helpfulness of each intervention. The current year class’ mean composite scores, between the pretest and post test increased by 6.9 points (32.5%). Student composite scores also demonstrated that the interventions were successful in helping a majority of students (64.7%) attain the curriculum goals. The interventions were also successful in increasing student scientific literacy by meeting all of Bloom's cognitive levels that were assessed. When compared with prior 2010-2011 and 2009-2010 classes, the current class received a higher mean post test score indicating a positive effect of the use of technological interventions. The survey showed a majority of students utilized at least some of the technology interventions and perceived them as helpful, especially the videos and PowerPoint® presentations.
