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. [Publisher's Text].
