This research aims to describe investigate possibilities of learning situations in mathematics concepts related to polynomial functions of the 1st degree ( In order Function ) with students from 1st grade of Technical Education Middle Level Integrated IFS - Campus São Cristóvão making use of a teaching sequence mediated by the use of a dynamic geometry software, Geogebra. To this purpose, a study, based on the ideas of Machado (2008 ), Pais (2011 ) and Oliveira (2013 ), based on the Engineering Curriculum discussed by Artigue (1996 ) with two classes from 1st Series Technical Course Intermediate Level Integrated was conducted Federal Institute of Education, Science and Technology of Sergipe - Campus São Cristóvão / SE, which formed study groups that we call group with the experiment and group without the experiment. At the end of the experiment it was found that the group with the experiment had better results than the group without the experiment. The data indicated that using a dynamic geometry software in a dynamic geometry environment provides a great interaction between the participants constituting a positive factor to learning, since they facilitate the construction of new concepts, provide a comparison between different forms of representation of a function, thereby enabling conditions for the participant to recognize the graphical representation of an polynomial function of the first degree as a straight, expressing the relation between the coefficients of the straight equation with its graphical and algebraic representations.
