X-TEC: Techno-Didactical Extension for Instruction/Learning Based on Computer - A New Development Model for Educational Software

In this paper we propose a new development model for Educational Software called X-TEC. It is based on the paradigms of software engineering applied to the construction of educational software. This model allows educational software developers to reduce the gap between instructional design and technical development. Our approach presents two overlapping extensions: the instructional model and the learning environment. The instructional model will be related to the instructor/educational software and the learning environment will be associated with the student/educational software. The X-TEC model promotes the interaction between these two extensions, allowing the deployment of a common development platform
