Resumo: This paper presents a qualitative research aimed at Math Teaching, developed in the first year of High School groups at Colégio Militar de Santa Maria (CMSM). It was questioned if Mathematical Modeling can help the students to know the risks caused by the use of alcohol and tobacco, while they construct their mathematical knowledge. For this purpose, a teaching experiment was done in the classroom, which has developed the math unit referred to the Exponential Function on the following issue: Drugs, specially the use of tobacco and alcohol , having the Mathematical Modeling as the methodological strategy. The focus was data from students daily routine, with the objective of verifying whether the use of this teaching-learning strategy facilitates or not the assimilation and construction of mathematical knowledge, as well as, the awareness of students about the evil effect caused by these drugs. For this purpose, the investigative steps and procedures proposed by action-research were used, which were divided at the same time in modeling stages. Some descriptive data were collected by means of questionnaires; two of them were applied at the beginning of the investigation, and a third one at the end. It was also used observation cards. The description and data analysis were done in each of the three instruments, as well as, the comparison of the first with the third one. The development of the teaching unit was also described. For a better understanding of the graphic behavior of the given function, the Excel spreadsheet was used. At the end of the research it was observed that the students came to know about the risks caused by the use of alcohol and tobacco, and that Mathematical Modeling has contributed significantly for it, while there was the acquisition of mathematical knowledge, which was developed together with the issue approach.
