I have borrowed the title of the book written by the educator Philippe Meirieu to write these reflections on the complexity of introducing children to the world of writing. It is a short book, included in the new Minerva collection published by the Rosa Sensat Teachers' Association, reviving the name of the collection offered at the beginning of the 20th century by the Barcelona Provincial Council and later by the Commonwealth of Catalonia.

The neurobiologist and International Science Teaching Foundation director, Héctor Ruiz Martín, has written several books to bring the evidence on learning and educational practices closer together.
