The presented work explores the innovative use of the SIR model (Susceptible-Infected-Recovered) in error management in the class- room. Introducing a novel approach, the study demonstrates how this model, initially designed to study disease spread, can be adapted to analyze the dynamics of error propagation in an educational environment. Using mathematical simulations, the article illustrates how errors spread among students and how pedagogical interventions can influence this propagation. Furthermore, it proposes innovative strategies to prevent and correct errors, while emphasizing the importance of timely and effective teacher intervention. In conclusion, this work opens a new path in classroom error management and deserves recognition for its originality and potential impact on learning improvement.
