Tecnologia e innovazione didattica. Storia trentennale di un percorso didattico di geografia quantitativa

This article describes a project in computer-mediated educational innovation for the teaching of geography which has been carried out at the Don Milani Experimental Middle School in Genoa. The project concerns a learning unit in quantitative geography that has helped to change the way this discipline is taught in the school. Given its special features and durability over time (28 years), this experience represents a benchmark for studying (a) the way in which a technology-mediated educational innovation project can germinate and grow to involve all school classes, and (b) the conditions that ensure sustainability over time.
