The new generation of Internet has notoriously been a decisive factor in direction-making of society through using interactive tools, which enables (re)build the knowledge. Here, everything becomes more dynamic and the interaction is increasingly more natural, both in visual terms and programming language. Thus, the Information and Communication Technologies, especially the Web 2.0, have been incorporated into educational processes. This article deals with the representation of scientific models using computer applications. Thus, it was planned and developed a technology product (interactive portal - Ealuno), using the resources of the Web 2.0, considering its use as an action tool for Physics teaching and learning. We discuss about how this way of presentation is inserted in Science/Physics class and described its functions. This is an investigation characterized as a participant research. In this case, we assume two positions, since we represent the Science teachers who teach for a technological society and the members of this technological society, that is, we represent the Physics classroom conditioned by new ways of communication from defined and legitimized positions in this social structure. Our results indicate that the student configuration allows different ways of record and representation of the reality that promotes to it a utility in the mediated action, being this utility in the interactivity power and in the access to virtual environments, permitting to provide to users interaction and motivation for the Physics teaching and learning process.

This article describes a hypermedia didactical material related to the following astronomical phenomena: Seasons, Moon Phases, Eclipses. Although being beautiful and close to our daily life, these contents seem to be complex to teach and difficult to learn. In this scenario, the hypermedia material presented can help students to understand these phenomena related to astronomy and enable them to interact with the course content. [ABSTRACT FROM AUTHOR]
