Lesson structures used in computer aided education

The paper proposes a structure for the lessons used in computer aided education environments (CAEE). CAEE is a software environment for generating and executing the lessons by users as administrator, teacher and pupil. A lesson consists of alternated explanations and testing sections. Both may contain graphical and text presentations. Graphics consists of static or dynamic images. An application is a set of parallel and concurrent processes synchronized by graphical variables. Graphic parallel processes are defined using visual languages. A multitasking mechanism oriented to graphical applications is included to execute the activities of the parallel processes. A knowledge base (KB) is proposed for prototype-instance model of static and dynamic objects.<>
