CD-ROM "Num mundo a cores" : concepção, aplicação e avaliação de um recurso multimédia para alunos do 3º ciclo do ensino básico

Tese de mestrado, Ciências da Educação (Tecnologias Educativas), Universidade de Lisboa, Instituto de Educação, 2010Este estudo descreve o processo de concepção, produção, validação e aplicação do recurso educativo ―Num Mundo a Cores‖, o protótipo de um CD-ROM com conteúdos multimédia destinado a alunos do 3º Ciclo do Ensino Básico. Explora a temática dos fenómenos da cor, conteúdo programático da disciplina de Educação Visual. Para além de ser produzido um recurso educativo multimédia, que poderá ser utilizado no futuro como ferramenta de apoio à prática docente, ao longo desta investigação desenvolvemos uma reflexão sobre em que medida e como a aprendizagem pode ser potenciada pelo uso das Tecnologias de Informação e Comunicação e quais os processos inerentes aos fenómenos de ensino e a aprendizagem mediados por computador. Descrevemos detalhadamente todo o processo de concepção e construção do CDROM, apresentamos as metodologias e os modelos adoptados na sua concepção assim como as opções tomadas durante a sua produção. Descrevemos ainda todo o processo de validação. Para responder às questões relacionadas com a aplicação do recurso em ambiente de sala de aula e qual o seu impacto na aprendizagem dos alunos, recorremos simultaneamente a metodologias de recolha e análise de dados qualitativas e quantitativas. A análise dos dados qualitativos, obtidos a partir de respostas abertas a um questionário de opinião, uma entrevista e observação de aulas, foi feita através de construções interpretativas usando a técnica de análise de conteúdo por categorias. Os dados quantitativos foram tratados estatisticamente recorrendo ao programa informático SPSS. A partir dos resultados obtidos no desenvolvimento desta investigação podemos concluir que um perito em multimédia, alunos e professores fazem uma avaliação muito positiva sobre o potencial deste recurso como ferramenta pedagógica.This study describes the process of design, production, validation and implementation of the educational resource "Num Mundo a Cores," a prototype CD-ROM with multimedia content for students in the 3rd cycle of basic education. The CD-ROM includes information about the phenomena of color which is a content integrated in the curriculum subject of Visual Education. In addition to being produced a multimedia educational resource that could be used in future as a support tool for teaching practice, throughout this research we studied on how far and in what way learning can be enhanced by the use of Information and Communication Technology and a what are the processes involved in the phenomenon of teaching and learning mediated by computer. We described in detail the whole process of design and construction of the CD-ROM, we presented the methodologies and models adopted in its design as well as the choices made during its production. We also described the whole process of validation. To answer the questions related to the implementation of the multimedia resource in the classroom and its impact on student’s learning, we used both qualitative and quantitative methods of collection and data analysis. To collect qualitative data we used an open-ended survey, an interview and classroom observation and the analysis was carried out through interpretive constructions using thematic content by category analysis as data analysis technique. The quantitative data was submitted to statistical treatment using SPSS software. From the results obtained through this research we can conclude that a multimedia system’s expert, students and teachers make a very positive assessment of the potential of this education resource as a pedagogical tool

Historical wines of Portugal: the classification, consumer associations and marketing implications

Geographical origin, use of traditional varieties and ancestral viticulture/oenology practices characterize wines classified as Historical Wines of Portugal (HWP). This study identifies the authenticity attributes consumers associate with this classification and assesses the relative strength of associations. A review of brand authenticity research and interviews with Portuguese wine producers (n = 3) and consumers (n = 12) were conducted to identify HWP classification attributes. Strength of attribute association was subsequently evaluated in an online questionnaire with a convenience sample of Portuguese wine consumers (n = 641), which included a measure of general wine knowledge and questions about the adequacy of different contexts for HWP purchase and consumption. Wine knowledge markedly affected the nature and strength of consumer associations. Compared to Aspirational Explorers, wine connoisseurs emerged as Heritage Gatekeepers, associating origin, cultural heritage, quality, production and at-home consumption more strongly with HWP, and tradition, wine age and out-of-home consumption less strongly. Market recognition of HWP as a novel and distinctive table wine classification, with well-defined and unique attributes, is thus likely to depend on consumers’ general wine knowledge. Related promotional activities targeting wine novices should first focus on educating them on HWP classification, whereas those directed at savvier consumers should emphasize wine authenticity cues instead.info:eu-repo/semantics/publishedVersio

Introducing insect- or plant-based dinner meals to families in Denmark: study protocol for a randomized intervention trial

Background: Plant- and insect-based foods are promising alternative protein sources. Previous studies have shown that introducing plant-based foods to the diet can reduce meat intake, but no such intervention has explored the effects of insect-based foods. Methods: This study aims to integrate alternative proteins to main meals of 80 Danish families through a 6-week two-arm randomized intervention trial to investigate acceptance, consumption, and potential for meat replacement. The primary outcome is the replacement of dietary meat protein with plant- or insect-based protein from the intervention foods assessed through change in daily meat protein intake, proportion of meat protein to total protein intake, and counts of dinner meals with meat and intervention products. Conclusion: The results of this study will contribute to research in alternative proteins and explore the effects of long-term exposure of meat replacement.

Emoticons e Letramento Visual: Pedagogia da Imagem

You are silent and all of a sudden your cell phone beeps warning that the message arrived from the whatsapp application, popularly known as zap. For a moment, the activity that is carried out is suspended so that the message is read, and an emoji (also known popularly as emoticon or smiley) - warns that the expected response is positive. Without any word written or recorded, you - and I also - understand that everything is well resolved. Based on this contextualization, based on the strength of the image as communication and also the ease access to the new Digital Information and Communication Technologies (DICT) in mobile devices, this article aims to propose reflections on the use of images for communication without words, but full of shared meanings.Você está em silêncio e, de repente, seu telefone celular emite um som avisando que chegou mensagem pelo aplicativo whatsapp, popularmente conhecido com zap. Por um momento, a atividade que se realiza é interrompida. Não se lê nenhuma palavra escrita; aparece apenas figurinha (conhecida como emoji, emoticon ou smile) avisando que a resposta que se esperava é positiva. Sem nenhuma palavra escrita ou gravada, você - e eu também – entendemos que tudo está bem resolvido.  A partir dessa contextualização, tomando por base a força da imagem como comunicação e, ainda, a facilidade de acesso às novas Tecnologias Digitais de Informação e Comunicação (TDIC) nos dispositivos móveis, o presente artigo tem como objetivo propor reflexões sobre a utilização de imagens para a comunicação sem palavras, porém repleta de significados partilhados

Evaluation of antimicrobial resistance of different phylogroups of Escherichia coli isolates from feces of breeding and laying hens

Animal and food sources are seen as a potential transmission pathway of multi-drug resistance (MDR) micro-organisms to humans. Escherichia. coli is frequently used as an indicator of fecal contamination in the food industry and known as a reservoir of antimicrobial resistance genes (ARGs). Microbial contamination as a major outcome for the poultry and egg industry and is a serious public health problem. In the present study we performed the quantification of β-glucoronidase positive E. coli in 60 fecal samples of breeding and laying hens collected in Portugal in 2019. Phylogenetic and pathotypic characterization, antimicrobial susceptibility, and detection of resistant extended-spectrum β-lactamase (ESBL) genes were assessed. The phylogenetic and pathogenic characterization and detection of ESBL genes were assessed by real-time PCR and antimicrobial susceptibility was evaluated using the disk diffusion method. Overall, E. coli quantification was 6.03 log CFU/g in breeding hens and 6.02 log CFU/g in laying hens. The most frequent phylogroups were B1. None of the isolates was classified as diarrheagenic E. coli (DEC). In total, 57% of the isolates showed MDR and 3.8% were positive for ESBL. Our study highlights that consumers may be exposed to MDR E. coli, presenting a major hazard to food safety and a risk to public health.This research received no external funding.info:eu-repo/semantics/publishedVersio

EVENTOS EXTREMOS DE PRECIPITAÇÃO E O RISCO DE FALHA ASSOCIADO EM PROJETOS HIDRÁULICOS NO ESTADO DE MATO GROSSO DO SUL, BRASIL

It is necessary to know the extreme occurrences of precipitation in a region for satisfactory design of infrastructure projects. Tropical climate regions are characterized for their heavy rainfall events during the summer, and in recent years, as a result of climate change, such events are becoming recurrent. A theoretical probability distribution model is typically used to extrapolate extreme events for high return periods. In this study, it was verified whether probability distribution models are efficient for an estimation of extreme precipitation events for the normative recommended return period. Five cities in Mato Grosso do Sul State, located the midwest region of Brazil, that have been affected by disasters caused by heavy rainfall were adopted as a case study. The results illustrate that the recommendations of the return periods used for the design of hydraulic control structures are insufficient to avoid damage caused by precipitation events, thus lending a high breakdown risk to the structures.É necessário conhecer as ocorrências extremas de precipitação em uma região para obtenção de projetos de infraestrutura satisfatórios. As regiões de clima tropical são caracterizadas por seus eventos de chuvas intensas durante o verão e, nos últimos anos, em decorrência das mudanças climáticas, esses eventos estão se tornando recorrentes. Um modelo de distribuição de probabilidade teórica é normalmente aplicado para extrapolar eventos extremos para altos períodos de retorno. Neste estudo, verificou-se se os modelos de distribuição de probabilidade são eficientes para estimar eventos extremos de precipitação para o período de retorno recomendado em normativas de dimensionamento de obras hidráulicas. Cinco cidades do estado de Mato Grosso do Sul, localizadas na região centro-oeste do Brasil, que foram afetadas por desastres causados por fortes chuvas foram adotadas como estudo de caso. Os resultados ilustram que as recomendações dos períodos de retorno utilizados para o dimensionamento das estruturas de controle hidráulico são insuficientes para evitar os danos causados por eventos de precipitação, gerando um alto risco de ruptura das estruturas

Influence of flock treatment with the antibiotic tylosin on poultry meat quality: results of a preliminary experiment

The veterinary antibiotic tylosin was administered to broilers at sub-therapeutic and therapeutic levels to study its effect on the quality of poultry breast meat. No statistically significant differences were observed in moisture content, pH, drip loss, colour and extent of lipid oxidation between the breast meat from treated and not treated birds. However, the cooking loss of the meat from the birds administered tylosin was significantly higher than that from the not treated ones. Additionally, the mean shear force of the breast meat was significantly lower for the sub-therapeutically treated broilers than for the not treated and the therapeutically treated ones. It was concluded that the level at which tylosin was administered to the broilers affected the quality of the breast meat, particularly its textural properties

frogger.concept: um novo paradigma de interacção do jogo clássico

Este artigo apresenta a conceptualização, desenvolvimento e implementação do jogo frogger.concept. O desafio de base para a construção deste jogo foi repensar o clássico Frogger das arcadas, de 1981. A implementação do remake, frogger.concept, implicou repensar todo o processo de game design do jogo, que segundo Kevin Oxland é constituído por: rules, feedback, interface, context sensitivity, goals quests and challenges, enviroment design e balance. A conceptualização técnica é também abordada, nas componentes de hardware e software; o objectivo final desta é a imersividade do jogador na experiência e a redução de barreiras físicas na experiência de jogo. A análise de resultados obtidos nos testes preliminares revelou que era necessário repensar os elementos gráficos do ecrã de jogo e aperfeiçoar o modelo de interacção para reforçar o equilíbrio da jogabilidade. Destaca-se ainda que foi muito positivo o feedback fornecido pelos jogadores que jogaram o frogger.concept
