摘 要：正This paper describes an online environment for learning Descriptive Geometry. Structured like an Intelligent Tutoring System, this interactive tool adapts teaching in accordance with the student’s performance. The instruction is based in solving Descriptive Geometry problems using a graphical applet. The problems are from an electronic library which catalogs them according to their concepts and difficulty levels and has a search mechanism used by a tutor module to select appropriate problems to offer the student when needed. The system maintains a model of the student to infer what he probably knows and what is still to be mastered. By comparing the students responses to the solutions recorded with the problems in the library, the tutor module is able to tell if the apprentice successfully solved a problem to, besides updating the student model, offer him help or another problem for increasing his development in the system.
