This article, which emphasizes the technical aspects, presents the results obtained within the ambit of Electra and Adaptweb projects, applied to the authorship and the adaptable presentation of the disciplines that compound the courses EAD in the Web. The aim is to allow the adequacy of tactics and ways to present the contents to the students from different graduation courses and with different learning styles, enabling different ways of presenting each one of the contents, adjusting it to each course and to the individual preferences of the participating students. This proposal was validated through a real case study, involving the Numeric Methods discipline at the State University of Londrina (UEL). This discipline is offered to three university courses: Mathematics, Engineering and Computer Science. In each course, the author-professor sets a sequence of concepts, with their respective levels of complexity, as well as with their respective examples, exercises and suitable complementary materials. The students may use different learning styles through the selection of the navigation way and of the presentation styles. The navigational adjustment aspects include navigation in a tutorial or in a free way, offering different alternatives of teaching tactics. The complete environment for the authorship and presentation of courses is available at the present moment at the phase of operational prototype. This prototype is being incorporated to the platform of EAD into some free software from the Federal University of Rio Grande do Sul (UFRGS). The environment is based on a set of components that back up the pre-authorship, adaptation of content and navigation phases. The implementation primordially uses the language of PHP programming, the database carrier MySOL and the XML language.
