This paper presents partial results of research that aimed to design, carry out and analyze the possibility of teaching mathematics based on the Study and Research Courses (SRC) in the secondary school. The implementation was carried out during one year, in a classroom of the last year of the secondary level (17-18 years old) during the normal classes, without realizing parallel classes. The questions of the SRC are related to the Microeconomics area, specifically to the point of balance of the simple supply-and-demand model. The Anthropological Theory of the Didactic (ATD) was adopted as a framework and the concepts of SRC and the dialectics introduced by Chevallard (2001, 2007) were used. The process is described analyzing the functioning of the dialectic developed to manage the SRC and their advantages and disadvantages.
