Aprendizagem significativa e supervisão: estudo exploratório de caracterização de um processo de mudança de práticas de um professor

Neste estudo aborda-se, de forma descritiva, o processo de mudança de práticas de um professor do ensino secundário, decorrente de uma relação de supervisão gerida pelo investigador. Essa mudança foi no sentido de um processo de ensino informado pela perspectiva construtivista, mais concretamente pela concepção de aprendizagem significativa tal como perspectivada por Ausubel. A elaboração do estudo envolveu várias fases que incluem a formação, a recolha e a análise de dados, a supervisão. A recolha de dados foi feita, por um lado, através de quatro inquéritos, dois para os alunos e dois para o professor, aplicados em dois momentos distintos: antes da mudança do processo de ensino/aprendizagem e após essa mudança e, por outro lado, através da gravação dos relatos do professor durante o processo de mudança. Antes do bloco de aulas relativo ao processo de mudança, professor e supervisor (investigador) abordaram conjuntamente a perspectiva construtivista e a aprendizagem significativa, e planificaram, também juntos, o bloco de aulas. O processo de supervisão foi enquadrado pelo modelo reflexivo. Os dados (dos inquéritos e das gravações) foram sujeitos a análise de conteúdo, tal como perspectivada por Bardin (1979). Verifica-se a existência de mudanças efectivas relacionadas com a melhoria da preparação das aulas, que tornou o professor mais reflexivo, e com a melhoria da relação pedagógica, que proporcionou aos alunos um papel mais activo no processo de ensino e aprendizagem. Conclui-se sobre a pertinência de repensar a formação contínua dos professores, de forma a incluir supervisores nas escolas que acompanhem os professores no sentido de melhorarem as suas práticas.

Mudança dos processos de negócios e adequação da TI nas empresas em decorrência da implantação do sistema público de escrituração digital SPED: um estudo de casos múltiplos

Companies have always been organized by processes, often imperceptible to its employees. With the advancement of technology, organizational processes currently run an organization through computers, and thus generate immediate information that is available to each sector. With the objective of seeking business information in real time, the government created the SPED - Public System of Digital, which involves three subsystems, which are the Electronic Invoice, Digital Accounting Bookkeeping and Digital Tax Bookkeeping. This system is revolutionizing the business structures when gathering, in an innovative way, all information and interlinked business processes. For the implementation of SPED, a revision in the organizational processes is required, since the information is generated and is sent online to the government, without mistakes. Thus the study aimed to analyze the change brought about by the implementation of the Public System of Digital SPED in the main business processes. In order to do so, we have performed a multiple case study involving three companies in the state of Para, two operate in wholesale and one explores agribusiness. The Data collection was performed by accounting professionals, IT and managers. According to the results obtained, it was found that in two companies, the IT infrastructure was capable of deploying the new system without major problems, while one company had more difficulties to cope with the new system. However, all companies had to examine its processes to make the customizations needed to fit. It was also observed that there is no IT Governance in two companies. Therefore, we recommend the use of an appropriate model, not only for the implementation of SPED, but as a way to manage and extract better results from investment in information technology

Trendtv : uma arquitetura para mudança automática de canais de TV baseada em redes sociais virtuais com graus de amizade e suporte a múltiplos dispositivos no cenário da TV digital brasileira

Due to the large amount of television content, which emerged from the Digital TV, viewers are facing a new challenge, how to find interesting content intuitively and efficiently. The Personalized Electronic Programming Guides (pEPG) arise as an answer to this complex challenge. We propose TrendTV a layered architecture that allows the formation of social networks among viewers of Interactive Digital TV based on online microblogging. Associated with a pEPG, this social network allows the viewer to perform content filtering on a particular subject from the indications made by other viewers of his network. Allowing the viewer to create his own indications for a particular content when it is displayed, or to analyze the importance of a particular program online, based on these indications. This allows any user to perform filtering on content and generate or exchange information with other users in a flexible and transparent way, using several different devices (TVs, Smartphones, Tablets or PCs). Moreover, this architecture defines a mechanism to perform the automatic exchange of channels based on the best program that is showing at the moment, suggesting new components to be added to the middleware of the Brazilian Digital TV System (Ginga). The result is a constructed and dynamic database containing the classification of several TV programs as well as an application to automatically switch to the best channel of the moment
