In this paper, we face the issue of argument and proving in geometry. Overcoming difficulties encountered by the students when moving from argumentation to proof may require suitable didactical interventions. Our contribution to research concerns the design of a specific computer-based didactic environment. We report how 14-15 years old students from high school conjecture and prove within the designed environment and we discuss the preliminary findings.
