Costruire indicatori per operativizzare la complessità sociale. Un esempio di costruzione e applicazione a partire dai dati del questionario insegnante di matematica INVALSI

In information societies, characterized by the consideration of human capital as one of the main levers of development, education plays a crucial role. For this reason, a knowledge of school organizations and education systems by means of non-evidence-based methods and using only incommensurable data becomes inadequate because it is considered to be of little use for its purpose. In this perspective, education indicators have become one of the privileged tools of analysis, especially since the 1990s, in order to measure the health of the school system; the need for comparable data on certain dimensions of the school system has caused them to undergo a surge in terms of interest and use, even if the consensus among scholars and professionals in the field is not unanimous. The aim of this article is to study the usefulness of certain process indicators, showing an example of their use related to teaching practices in mathematics teaching. The way to make synthesis indicators will be highlighted in detail, then showing their ability to summarize the phenomenon at a descriptive level, but also their informative potential in relation to outcome indicators.
