The strategies in the Teaching-Learning-Evaluation Process (PEAE) have a preponderant performance. The main objective was to analyze three teachers in their role as students in this process, in the subject of upper middle level stoichiometry at the National Polytechnic Institute in 2016. Traditionally, the PEAE has focused on the calculation and balance of chemical substances such as learning strategy. This leads to the difficulty in the execution of arithmetic and algebraic operations as the only form of learning and its consequent evaluation, contributes to the high rates of discouragement, disapproval and attrition. The EDMODO platform was used in four phases: documentary inquiry, identification of previous knowledge, experience of a non-routine situation, and pedagogical meaning and meaning. The findings show the teacher's self-reflection in his role as a student and in his teaching work.
