Abstract The use of animals for the training of students through the execution of experiments and  emonstrations is not new. However, this use can report aggravating that may hinder rather than contribute to learning, because many undergraduates do not feel free to use animals in vivo in practical classes. On the other hand, the evolution of the intensive use of Information and Communication Technologies came to question the traditional teaching paradigms. The alternative methods come to comply with ethical, moral or religious principles of these undergraduates who oppose such use. The teachers need to have an ethical position regarding to the use of non-human animals in vivo in practical classes, because their role is to guide the student in the question of the man in relation to other animals, showing the value of life in any circumstances, whether human or not, just as well to present the legal issues involved in this context. From the results of a survey, it was drawn up this present proposal for alternative methodologies to the use of non-human in vivo animals in practical classes. These metododologies, such as the case of the use of softwares, can generate the same knowledge about the subject to be studied. Key-words: Information and communication technology in education. Ethics in research. Science Teaching. Education in Health. Animal experimentation.
