1 The way to teaching corrosion based on visual inspection: student's opinions Maria Victoria Biezma1, Sonia Braunstein Faldini21Universidad de Cantabria, Santander, Spain. 2 Universidade Presbiteriana Mackenzie, São Paulo, BrazilSummary This paper collected the student’s opinions about practical lectures that point out visual observation of corrosion problems in real conditions, attending the particular topic of corrosion in Engineering courses, as Grade, Master as PhD, related to Materials and Engineering Science, i. e. Chemical Engineering, Mechanical Engineering, Marine Engineering, etc.. In order to impart the practical lectures, two methodologies of looking at a problem of corrosion were applied: the first one is a teacher-student interaction during walking encouraging to the discovery of corroded metallic structures in situ and a discussion regarding to it and the second one is exclusively directed to the student, who will identify situations of corrosion in the workplace, at home or on the street; the student works alone and had to defend his opinion suggesting what kind and the potential causes of corrosion observed. The student also proposes solutions to minimize corrosion and finally argues with the teacher. The high level of participation has provided the choice to establish a representative idea of the learning method based of the use of this sense: visual inspection; in order to be sure of the results, the authors designed a short and clear survey to collect the student´s opinions. They also comment that this type of class allowed a better understanding of the corrosion theory. 1 Introduction Corrosion is a natural process that implies high impact as social, environmental and economic. The catastrophic failures are the worst corrosion effect but can appear its damages effect implying a percentage loss of chemical-physical-mechanical proper-ties in metallic structures, components, in artefacts etc. There are a lot of metallic system affected by the corrosion effects and the identification of it can be easy or really complex since appears in a variety of different forms and morphologies that are directly affected by the chemical composition as metallurgical factors of the metallic system, environment properties, mechanical effects and so on  Some examples of
