The author, an e-learning researcher and computer science teacher, discusses an educational path within the context of "Alternanza Scuola Lavoro'' (AS-L, i.e. work-related learning). This proposal involves Economics, Mathematics and Philosophy as a means to support the teaching of Computer Science, Economics, Law and Mathematics in the upper classes of a vocational technical high school. According to the welfare economy and collective intelligence, the strategic choice falls on a blended course via Moodle, by which each participant gets one hundred hours of AS-L.
