The article was developed in a first semester class of Mathematics Degree in the Federal Institute of Education, Science and Technology of Bahia (IFBA), whose objective was to verify if the methodology of Emergency of Concepts can identify the reorganization of the thought in the study of the logarithmic functions.The research was qualitative, but the methodology could be modeled throughout the process.The theoretical contribution used to mark this study is found in Guy Brousseau's Theory of Didactic Situations and in the use of Technology in Mathematical Education.The analysis of the obtained data happened from the choice of two free softwares, the Tropes (for semantic analysis) and Gephi, for analysis of Networks; both make up the methodology of Emergency of Concepts.The positive feedback from this research was produced throughout the application of the didactic sequence, analysis and devolution of the students to the end of the work.
