Sfide per la sintesi della ricerca valutativa.

Evaluative research and research synthesis are connected from the drive to a constant reflection on the organicity of the available knowledge, its reliability, and the chance of considering it transferable beyond the original contest. The pluralism that characterizes evaluative research presents specific challenges related to the variety of approaches, designs, and questions. The reporting mode of processes and results - with the coexistence of heterogeneous literatures, lexicons, and approaches - require a specific reflection. Developments on the research synthesis front make it possible to identify different pathways to reach various objectives. Those developments are often related to collaborative initiatives that provide platforms for coordination, debate, and methodological development. The construction of collaborative networks involving the academic and professional community is the first step to respond to the main research synthesis challenges in the evaluative research field.
