Abstract(s)
A Internet é uma grande fonte de informação pela sua interatividade, facilidade e baixo
custo de acesso, no entanto, os conteúdos disponibilizados podem não ser confiáveis e
comprometer as tomadas de decisão. A possibilidade de qualquer pessoa publicar
informação na Internet sem qualquer controlo é um dos fatores principais para a falta da
qualidade dos conteúdos disponibilizados (Silva & Castro, 2008).
Este trabalho advoga uma estrutura global para a qualidade de sítios Web, que se baseia
em três dimensões principais (conteúdos, serviços e técnica), propostas por Rocha
(2012). A dimensão qualidade dos conteúdos foi a que obteve mais relevo neste
trabalho, pelo facto de até à data existirem poucos trabalhos publicados nesta área e por
ser um fator crucial nas tomadas de decisão e na realização de tarefas do quotidiano.
Além de uma revisão bibliográfica sobre a qualidade de sítios Web e qualidade dos
conteúdos de sítios Web, pretendeu-se investigar a perspetiva dos utilizadores em
relação à qualidade dos conteúdos de sítios Web do ensino básico e secundário
português. Foi averiguado se os conteúdos disponíveis nos sítios Web das escolas
apresentavam qualidade segundo um conjunto de 33 atributos definidos na abordagem
de Caro et al. (2008). Consequentemente, aplicou-se um questionário a 96 professores
do ensino básico e secundário português, obtendo-se uma taxa de resposta de 68,8%.
Recorreu-se à ferramenta SurveyMonkey para criar o questionário e ao Microsoft Excel
para o tratamento dos dados recolhidos, aos quais se efetuou uma análise descritiva.
Concluiu-se que a maioria absoluta dos respondentes concordou que 23 dos atributos
(atratividade, acessibilidade, atualidade, aplicabilidade, adequabilidade, plenitude,
credibilidade, disponibilidade, compreensibilidade, especialização, reputação, precisão,
fácil utilização, flexibilidade, interpretabilidade, objetividade, oportunidade,
organização, relevância, representação consistente, confiança, tempo de resposta e valor
adicional) estavam disponíveis no sítio Web da sua escola e por maioria relativa 5 dos
atributos (duplicabilidade, expiração, inovação, representação concisa e rastreabilidade).
The Internet is a great source of information by its interactivity, ease and low cost of access, however, the content available may not be reliable and may compromise decision making. The possibility of anyone publishing information on the Internet without any control is one of the major factors for the lack of quality in the content available (Silva & Castro, 2008). This paper advocates a structure for a global quality evolution of awebsite, which is based on three main dimensions (content, services and technical), proposed by Rocha (2012). The dimension content quality was the main focus in this work because to date there are few published studies in this area and also because it is a crucial factor in decision making and carrying out everyday tasks. In addition to a literature review on quality of Websites and content quality of Websites, it was sought to investigate the users' perspective on the content quality of Websites of primary and secondary Portuguese school. It was examined whether the content available on the Websites of the schools present quality according to a set of 33 attributes defined in the approach of Caro et al. (2008). Consequently, a questionnaire was applied to 96 teachers in primary and secondary Portuguese school, yielding a response rate of 68.8%. The SurveyMonkey tool was used to create the questionnaire and the Microsoft Excel tool was used to process the data collected. A descriptive analysis was applied to these data. It was concluded that the absolute majority of the respondents agreed that 23 of the attributes (attractiveness, accessibility, currency, applicability, amount of data, completeness, believability, availability, understandability, specialization, reputation, accuracy, ease of operation, flexibility, interpretability, objectivity, timeliness, organization, relevancy, consistent representation, reliability, response time and value added) were available on the Website of their schools and a relative majority on the 5 attributes (duplicates, expiration, novelty, concise representation and traceability).
