The chapter is organized as follows: first, the authors introduce the general background which prompted the research activity, and after, they present the MATCOS programming environment and elucidate its pedagogical-educational paradigm, technical characteristics, and use in everyday teaching through an example. Finally, the authors give a detailed description of the experimentation and the results obtained in the last few years. Future trends and conclusions round off the paper.
