Freinet is one of the most famous French pedagogues but his work is the subject of many misunderstandings and misleading simplifications that the author dispels by returning to the fundamentals of the thinker. Free writing, the school walk, the printing press, the student council, etc. are indeed so many techniques developed by Freinet from pedagogical, political, psychological or epistemological theories. But do these methods and ideas still have a place today? Fueling the French debate on the school, Baptiste Jacomino shows us that Freinet's system is open, not exempt from criticism, but also conducive to evolution and adaptation at any time and in any place.
