Valutare gli impatti della formazione in servizio degli insegnanti: una ricognizione

The effectiveness of in-service training and professional development interventions for teachers is a crucial topic within the field of education and educational research. This study examines the concept of “impact” and how it is understood and assessed in the literature. As part of a systematic review currently being conducted across academic databases, preliminary syntheses (meta-analyses and systematic reviews) have been extracted to determine the constructs and methodological tools used to measure impact in research on teacher training. The findings highlight a focus on assessing outcomes across a variety of levels, supporting the discussion of “impacts” of in-service training, observable through diverse methods and tools, and targeting at least three areas: teachers, students, and the broader educational context. This study thus provides a comprehensive synthesis that may inform educational policies, continuous training practices, and educational research in the field.
