The ‘supply chain’ of teachers’ digital skills training. The TPACK traceability in the teachers’ trainers

Starting from the stimuli coming from the TPCK model, the work invites to discuss the type of technological competence required today by the teacher for a 'wise' and effective use of digital tools at school. The 'supply chain' metaphor will be used in order to describe the epistemic process that transforms European priorities into national competences of teachers. Specifically, a model of 'traceability' of the TPACK - that from the DigiComp Edu Framework leads up to the local training in the school-centres pole through the Italian National Digital Plan (PNSD), obtained from a survey using a questionnaire - will be proposed in order to reflect on the coherence between the general priorities and the actual formulation
