The "good teaching practice" is a set of actions taken by the teacher to make improvements in relationships, processes and activities, all aimed at producing positive results, in our case, the students' acquisition of basic skills. In social Psychology and, specifically in the area of persuasion and attitudes change, we know that persuading people depends on different factors, from many variables of the source, the message, the recipient, etc. We understand teaching as an effort to persuade the student, not only in attention, engaging, collaborating and performing tasks, but also in being convinced that all these actions are carried out because they want, they like it or even because it is useful. In persuasion, an attitude is defined as the relatively stable global evaluation that people make about any content, context, person or thing [1], [2], [3]. That is, students need to have not only a favorable attitude, but also a "strong" attitude. There are different tools for having a strong attitude and for predicting better the behavior in the class. The key is in the processing of information. The Elaboration Likelihood Model [4], [2] is an excellent tool for teachers to start working with students in order to build positive contributions on the attitudes, beliefs, behaviors and, as a result, knowledge. Considering persuasion we know that we need to convince students for the contents every single day.
