This research aims to assess Learning Objects (OA) digitally related to the theme "digestive system" based on some principles of Cognitive Theory of Multimedia Learning (CTML) Mayer (2005). OA was selected for its easy access, zero cost for the end user, presentation in Portuguese language and appropriateness for middle level students. It was observed that most of these instructional models did not give much emphasis to the principles of this theory in their construction and production. The results of this study indicate that, in relation to the "digestive system" content, there is a need for the planning and construction of OA to be guided by principles and criteria aiming to make the use of multimedia resources more efficient, and able to make the necessary adjustments and corrections so they can meet the principles of CTML satisfactorily.
