Abstract

Starting from the considerations on modern school of some important scholars, which highlight the complexity of the school system, an analytical path is outlined to identify the best strategies by means of a mathematical model. The method followed is the analytical hierarchical one of Saaty that starts from the investigation of the various objectives, criteria and strategies, and indicates procedures to assign qualitative judgments and to transform them into numerical scores. In particular the AHP procedure is applied to find the degree of effectiveness of various strategies for teaching English, in relation to possible contexts that may arise.
