This work is part of the research line Information Technologies and Mathematics Education and aims to analyze the contributions of a Dynamic Geometry software, in particular GeoGebra in the interpretation and analysis of affine and quadratic functions by the students of a Bachelor's Degree in Mathematics. For this, a research question was formulated: What are the contributions of GeoGebra for the study of affine and quadratic functions in a Mathematics course? First, a proposal was elaborated with nine activities to be developed in five four-hour face-to-face meetings using the dynamic geometry software GeoGebra. Based on the theoretical assumption of Raymond Duval s Semiotic Representation Records we elaborated and analyzed the activities. The research qualitative methodology adopted was centered on the Design Research aimed at improving the educational activity proposal to be applied to future students entering the Mathematics Course. The research was carried out with the use of the following instruments to collect data: photocopied activities, pencil-paper media, Screen capture software, audio-recorded semi-structured interviews and protocols of the activities developed by the students. After analyzing the data, it was concluded that possibly the visualization allowed by the GeoGebra dynamism attracted much attention of the students and had a significant contribution to carrying out the activities. In the end of this work, there is a new proposal of improved activities based on the results obtained from the analysis of the activities performed by the students
