In this case study, the objective was to contrast quantitatively and qualitatively the achievement of mathematical modeling learning (acquisition of formal language, construction of the model, solution and interpretation of the model and application of the model) between a systemic approach that used the GeoGebra software and a conventional approach. This research had a mixed, descriptive and partially experimental scope. It was carried out in an online modality with a non-probabilistic sample of 130 engineering students, segmented into a control group and an experimental group. Regarding the results obtained, it was found that at the end of the three stages of the study, on a scale of 0 to 10, the control group achieved an increase in performance of 3.01 and that, after four months, 1.95 points were lost. While the experimental group obtained an increase in performance of 4.66 and after four months it had a reduction of 0.94 points. The actual increase in performance from the diagnostic stage to the end point was 1.06 for the control group and 3.72 for the experimental group. In quantitative terms, this represents a statistically significant absolute difference between the control and experimental groups of 26 percentage points, which is equivalent to a relative difference of 250.94% between the diagnosis and the stage carried out four months after the intervention. The increase in performance was greater in the experimental group. The results indicate that the proposed systemic learning approach assisted with GeoGebra could have a positive impact on performance in mathematical modeling.
