Logical Intelligence Enhancement Test: a measure for the evaluation of logical skills in primary school

Il presente lavoro si inserisce in uno studio pilota condotto nell’anno scolastico 2018-2019per valutare l’efficacia del Logical Intelligence Enhancement Programme (LIEP, Calvani, Peru,& Zanaboni, 2019), un programma composto da tavole di logica verbale e numerica volte asviluppare il ragionamento logico e le capacità metacognitive di studenti di quinta primaria.All’interno di questo studio è stato sviluppato il Logical Intelligence Enhancement test perstimare gli effetti del training sulle abilità logico-verbali. Il contributo presenta la costru-zione del test, le sue caratteristiche psicometriche e la validazione. A tal fine, lo strumentoè stato somministrato a un campione di 173 studenti di classe quinta primaria nell’area diPalermo e Firenze.Il LIEP Test si compone di 22 item e include otto dimensioni di esercizilogici come il completamento di tabelle o serie di numeri, la risoluzione di problemi nu-merici o geometrici e tavole di inferenza logica. This work is part of a pilot study conducted during 2018-2019 to evaluate the effectivenessof the Logical Intelligence Enhancement Programme (LIEP, Calvani, Peru & Zanaboni, 2019),a program which consists of logical-verbal and numeric exercises to enhance logical rea-soning and metacognitive skills of fifth grade students. During this study the Logical Intel-ligence Enhancement test was developed to measure the effects of the training on thelogical-verbal skills. This paper describes the development of the LIEP test, its psychometricfeatures and validation process. For the validation the measure was administered to a sam-ple of 173 fifth grade students in Palermo and Florence. The final version of the test consistsof 18 items and includes eight dimensions of logical exercises, such as tables to be com-pleted, numeric series, problem solving and logical inferences.
