SUMMARY:

This investigation is part of a research project focused on mathematics teaching and learning within dynamic geometry environments. Through an exploratory study, the interactions of prospective mathematics teachers are illustrated as they engage in tasks involving the isometries of rational function graphs on the GeoGebra platform. A review of existing research reveals a wealth of studies on technology in education but highlights a scarcity of work linking rational functions to isometric transformations. The theoretical framework emphasizes the importance of using virtual environments for mathematics teaching and learning and of designing tasks suited to these environments. Chapter three focuses on presenting the GeoGebra platform and the activities proposed during fieldwork, as well as analyzing the introductory activity with a focus on participants' responses within GeoGebra Classroom. The final chapter provides a detailed analysis of the activity sequence, which prioritized the exploration of sliders, function transformations, the construction view, and the linking of geometric and algebraic representations. Data collection relied on activity responses recorded on the platform and manually transferred to Excel spreadsheets, supplemented by screenshots whenever analysis of the construction view was required. Chapter five presents the educational product: a workbook containing the activities developed during the research. The contribution of this work lies in addressing isometries in conjunction with the study of rational function graphs through an interactive approach within dynamic geometry environments.
