Evaluación de la matemática temprana mediante la primera validación italiana del Early Numeracy Test-Revised (ENT-R)

Abstract

The purpose of this research was to adapt the Early Numeracy Test - Revised (ENT-R) to the Italian population. It is a tool for the evaluation of mathematical competence for children aged 4 to 7 years, designed and calibrated by Van Luit y Van de Rijt (2009). The test is designed to assess the competence of early mathematics and mathematical learn- ing and it is useful in identifying possible problems and in the specific areas of: concept of confrontation; classification (relative to the amount); one correspondence-ad-one; seriation; verbal count (use of cardinal numbers); structured count (count synchronously and in abbreviated form), resulting count; general knowledge of numbers and estimate on the line number. The test has been calibrated for a sample of 633 children (333 males and 300 females) from 14 schools in Rome and Trieste. The test analysis of validity and reliability (Cronbach’s alpha 0.93) allow to consider the ENT-R as an appropriate and useful tool for evaluating mathematical knowledge in Italian students at the end of kindergarten and the first years of primary school.
