Abstract

By teaching mathematics with a focus on the development of mathematic skills, students may learn to use math in various real situations rather than simply mastering formal mathematical concepts. Having this in mind, we planned and developed an educational program for the learning of mathematics, by integrating mathematical modeling and graphing calculators so that freshman students repeating the Introduction to Mathematics course in the Social and Economic Sciences School at a Venezuelan public university, would achieve mathematical skills connected to real functions. 17 volunteer students participated in this study, carried out as a field research project with an evaluative nature  through  the  methodology  program  assessment.  The  students’  productions  were  analyzed,  finding out that they were able to solve problems with the help of a calculator and to gain such mathematical skills.
