La formazione degli insegnanti di matematica e le valutazioni standardizzate: primi risultati di un progetto di ricerca nazionale interdisciplinare

Abstract

Abstract – In recent years, many research studies in mathematics education have drawn on the results of standardized assessments. The results of standardized tests can highlight and quantify relevant macro-phenomena, which can be interpreted according to the methods and results of mathematics education research in order to provide useful information and interpretative tools for teachers. In this paper we describe a study carried out by the Research Group “INVALSI e Didattiche Disciplinari” – Osservatorio SIRD, aimed at investigating how more than 500 in-service primary school mathematics teachers interpret some statistically significant errors emerging in the INVALSI mathematics tests for fifth grades. The study focuses on teachers' awareness of some aspects of mathematics learning, including awareness of the main causes of students' errors and perceptions of the difficulties of some INVALSI tasks.
