This study presents the analysis of the didactic contract established in the approach of content periodic properties of the chemical elements in the first discipline of general chemistry offered by the Chemistry Degree course of the Universidade Federal Rural de Pernambuco. According to Brousseau, the didactic contract refers to the clauses, partly explicit, but mostly implicit, that regulate the division of responsibilities and expectations between teacher and student, in the management of a knowledge. We watched the classes from the beginning of the subject approach to the introduction of the following content. In order to obtain data, we made audio and video recordings and then separated some class clippings that presented ruptures, negotiations and didactic contract effects for analysis. The results point to a significant number of renegotiations and contract effects, especially the Topaz effect, which is evidenced from an explanatory posture of the teacher in the search of masking unreached goals in the teaching and learning process.
