The research project MoTeL (Models of Teacher Learning. Investigation of Teacher Continuous Professional Development Models at the Level of the Education System, the Organisation and the Individual) aims to explore the system, organisational and individual level factors that influence teachers’ continuous professional development (CPD) and learning and their relationships, as well as the ways how the individual, organisational and system-level effectiveness of the various stages of CPD can be measured. This project no. 128738 has been implemented with the support provided from the National Research, Development and Innovation Fund of Hungary, financed under the K_18 funding scheme.
