Educational Matrioska collects the pedagogical experience of the subject: "Academic Project" of the Master's Degree in Architectural Communication (MACA) as specialized training of the Doctorate in Architectural Communication of the ETSAM-UPM. The main objective of the subject is "how to teach to teach", as part of the learning of architectural communication. It is a 45-credit subject, which develops intensively in two consecutive weeks. After the first three editions of this subject: Matrioska (16-17), Madrid Heroes and Vilains (17-18) and Mestizo Madrid (18-19), we analyze the successes and mistakes of an innovative pedagogical experiment, which tries to give tools for teaching through empowerment, selflearning and self-knowledge of students so that they can enhance their abilities to address new challenges in real-time practical teaching to other students (learn by doing), reversing roles and eliminating hierarchies.

One of the most important issues in the contemporary debate, is the one concerning the long-term sustainability of society as we understand it today. The human being is recovering the lost sensitivity that conceived us as part of the natural cycle of life. We have finally understood that we cannot be self-sufficient and independent of the natural environment which surrounds us. Beyond respect and care, we'll find that the gateway to the infinite knowledge that nature provides us at all levels and at all scales is open.
