If you want to know what these four letters mean, please read "Los ingenieros de caminos" by Fernando Sáenz Ridruejo (ed. Colegio de Ingenieros de Caminos, Canales y Puertos, 1993).
Nowadays it is rather improbably that you will get the real concept, at least in some High School institutions. Nobody knows and nobody will explain to you.
Well, let me drop some thoughts. You will be able to teach something if you have learnt it, if you have done it. Our students don't need actors, politicians, governors, bureaucrats... but teachers: a teacher is side by side with pupils; and he is side by side with reality too.
Nowadays those want us to be called Civil Engineers. The more those say the word "quality" (regarding to teaching and learning) the less you can expect from them.
Students must not be blamed because of neither the educative collapse of the Engineering nor the fall of the Institution so called University... long time ago.
I'm afraid we will keep writing about this... unfortunately.
