CATARINA is a powerful and innovative educational resource which couples scientific rigor with the attractiveness of video games by permitting students to navigate easily through course lessons by means of videos, texts, graphics, audio and animation. Three dimensional display of electron spinning of molecules association/dissociation was shown with ShareVision via an analog INMARSAT-A, in two-way, interactive mode between SENAI in Florianopolis, Brazil and UNESCO in Paris, France. The software also allows students to interact with the experience or demonstration being presented -- an "experiential learning" in a virtual laboratory where students can observe changes frame-by-frame at a specified rate or velocity and even "rewind" the animated sequences and repeat them. Projected mainly for the teaching of the natural sciences such as Chemistry, Physics and Biology, CATARINA's main advantage is to replace traditional segmented static images and graphics with animated sequences, demonstrating processes as they occur in nature. CATARINA not only personalizes learning process, but also enriches the fundamental topics of each unit of the school programs with text, sound and dynamic animated sequences. It is geared to the satisfaction and participation of the student thus serving as a positive reinforcement and promoting the continuation of studies.
