Resumo. Este artigo descreve o desenvolvimento de um aplicativo para ensino Cenário de usoMuitas são as oportunidades para profissionais qualificados da área de Tecnologia da Informação (TI) e existe o desafio, no Brasil, de atender à demanda de mão de obra do mercado de TI, que tende a ampliar sua participação no PIB em 6,5% até 2020 [Alvarenga, 2012]. Isso implica na necessidade de abertura de cursos para formação de profissionais com conhecimentos básicos aplicados, que atendam à demanda imediata do mundo do trabalho, para possibilitar, nesse, sua rápida inserção. Entretanto, sabe-se que poucas são as pessoas interessadas em ingressar na área.

Temporal data models have proven to be convenient to specify applications, allowing the representation of the temporal evolution of data. Several temporal data models were proposed in the last 20 years with this purpose, but no commercial implementation of a Temporal Database is still available. This paper presents an Integrated Temporal Database Environment implemented on top of a conventional database. Using this environment, a user can handle the specification, the data definition and the queries as thought the database implements the temporal data model. The environment performs the mapping from the temporal conceptual schema to the correspondent database, and of the queries expressed in the temporal query language to SQL. Data definition is controlled based on the state transition rules of the temporal data model, keeping thus the temporal integrity of the database. The underlying conventional database keeps transparent to the user. * This work was partially supported by CNPq -Brazil 0-7695-0810-3/00 $10.00 0 2000 IEEE

As a proposal for a methodological strategy for teaching and learning chemical transformations in science or chemistry classes, this paper presents the learning object Pensaqui. It was developed through joint work between teachers and students at the IFRSCanoas and UFRGS(both located in Southern Brazil), integrating the areas of Chemistry and Design. In a recreational and contextualized fashion, Pensaqui proposes students to expose their ideas on two problem situations through the use of different levels of representation (macroscopic, symbolic and submicroscopic). The pedagogical aim proposed is to help students to be aware of their individual theories, differentiating them from the scientifically correct theories, where the understanding of matter as something discontinuous and the conservation of nonobservable properties are essential core concepts for the understanding of chemical transformations

Resumo: Este trabalho apresenta a proposta de uma fábrica de objetos, com foco na educação profissional tecnológica. O objetivo principal é aproximar os educandos do mundo do trabalho, com técnicas, ferramentas e tecnologias utilizadas no mundo real. Com isso, busca-se qualificar a pesquisa e a produção científica, bem como a produção tecnológica. Outro aspecto considerado importante é a possibilidade de realizar experimentações teórico-práticas na área da educação, alinhadas com a área da Computação. Palavras-chave: Fábrica de software. Métodos ágeis. Objetos educacionais. OBJECT FACTORY: A MODEL FOR THE PROFESSIONAL QUALIFICATION Abstract: This paper presents a proposal of object factory, with focus on technological professional education. The main objective is to approach the students of the work world, with techniques, tools and technologies used in the real world, to qualify scientific and production research as well as technology production. Another important aspect presented is the possibility to accomplish conceptual and practical experiments in digital learning objects with the vision of Computer Science area. Keywords: Software factory. Agile methods. Learning objects.
