Presentation of the book "a Classroom, or a cage"

Are todays classrooms as scary as some people paint them to be? Is education worse now than before? Do teachers have adequate training? Is the School a building on the verge of collapse? This essay responds to these questions from the author´s own experience, with many years of teaching behind him—at various levels, including university, and also as a teacher trainer, professor and director of a center-educational public Secondary school, classified as a school of special difficulty.
