摘要：The purpose of this work is to present a methodology to create educational scripts based on virtual reality. The methodology is defined by using a set of rules that should be sequentially executed when creating a virtual world. The basis of this methodology is an adaptation of a software engineering technique named use-case [1]. A use-case represents a course of events initiated by an actor. The purpose of these use-cases is to specify the interactions between the actors and the system. The methodology is used in conjunction with an user/virtual world interaction model, composed of scenarios, events, objects and actors. Scenarios describe the relation between scene components. Objects are modeled as 3D pictures. Events are actions performed by actors when they interact with objects or other actors. The intention here is to provide a computational tool that helps to develop the students creativity as they use the virtual worlds, based on the Psychology of Creativity [2] and on J. Piaget's Cognitive Psychology [3]. During the development of this work, a virtual world has been created in order to demonstrate how to apply the afore mentioned methodology. The theme of this world was astronomy for children, based on Monteiro Lobato's book "Viagem ao Céu" (A Trip to the Sky). By interacting with this world, the users become actors of a story, where their actions modify that story as it evolves. As a consequence of the approach used here, the students become active learners, as the system requires them to make decisions and act in order for the story to evolve. Also, in this environment, the students are more than simple observers, since they are required to have an active participation and a high level of interaction, leading to an instrument that may be seen both as a learning support tool and as a entertainment tool.
