Complexity and future: these are the key categories which guided the reflection of the volume Primaria oggi. Complessità e futuro, which are read in a different key within school and for school, especially in primary school, between initial teacher training, ongoing training and planning. The first part of the volume solicits theoretical visions and didactic-pedagogical alternative guidelines through the essays contained in it. The second part, on the other hand, offers a rich and dense set of experiences telling about a committed and vibrant school, which is constantly updated and renewed. The topics of classroom management, internship for initial teacher training, special educational needs, vertical curriculum and assessment of learning have been chosen as strategic vectors to rethink tomorrow's school starting today.
