Abstract
Perhaps the most significant context in which (formal) education takes place is the lesson. Most of us – whether or not part of the education system – have come to identify the concept of lesson with school lessons. The study shows that we can, however, encounter lessons at every step in our lives and at any time. The important thing is to be able to see them, understand and learn from them; not pass them by, indifferently and superficially. In this context, the study proposes a wider and more nuanced definition of the concept of lesson and captures its main dimensions.
