Abstract (2. Language): 
In this paper, some of the concepts behind Intelligent Tutoring Systems (ITSs) are used to elaborate a conceptual framework for error remediaton with multple external representatons (MERs) applied to learning objects (LOs). For this purpose, we have developed an LO for teaching the Pythagorean Theorem. This study analyzes the process of error remediaton by classifying mathematcal errors and provides support for the use of MERs in this process. The main objectve of the conceptual framework is to assist the individual learner when rectfying a mistake made during interacton with the LO, due to either carelessness or lack of knowledge. First, we will classify mathematcal errors and explain their relatonship with MERs. Then, the concepts behind the conceptual framework will be presented. Finally, we will discuss an experiment with an LO developed with an authoring tool called FARMA, in which the conceptual framework is used to teach the Pythagorean Theorem.
