The paper introduces an educational path on mineral fresh water, in two fourth classes of a primary school. The specific contents refer to the awareness of fresh water as the first food for human and the daily practices to save it, even to protect animal species of freshwater ecosystems. Within one of the two classes, the experimental group, a pratical – laboratory teaching approach was used, with scientific experiments; in the second class, the control group, a frontal approach was used, which involved the direct transmission of the contents. The main goal is to detect whether the laboratory approach is more effective than the frontal approach, for understanding the concepts. It is also intended to capture opinions of primary school science teachers and parents of pupils, regarding the validity of the laboratory approach. To answer the first question, the numerical data of the verification test, of both the groups, were compareted. To satisfy the second question, the answers of two questionnaires were viewed, one for science teachers and one for parents. The laboratory activities allowed the experimental group to obtain better results than the control group, although the gap in the final learning levels, achieved by the two classes, is not particularly large. In addition, the majority of both science teachers and parents consider the laboratory more useful for learning, because it promotes memorization. The research shows that experimental activities facilitate, in greater way, the understanding and memory of concepts over time, although even the frontal lesson is profitable when integrated.
L’elaborato introduce un percorso didattico sull’acqua dolce minerale, in due classi quarte di una Scuola Primaria. I contenuti specifici fanno riferimento alla consapevolezza dell’acqua dolce come primo alimento per l’uomo ed alle pratiche quotidiane per risparmiarla, per proteggere anche specie animali di ecosistemi ad essa riferiti. Entro una delle due classi, gruppo sperimentale, è stato utilizzato un approccio didattico pratico – laboratoriale con esperimenti scientifici; nella seconda classe, gruppo di controllo, un approccio frontale, che implicasse la trasmissione diretta dei contenuti. Obiettivo principale è rilevare se l’approccio laboratoriale è maggiormente efficace, per comprendere i concetti, in confronto all’approccio frontale. Si intende, altresì, cogliere i pareri di insegnanti di Scienze di scuola primaria e dei genitori degli alunni, in merito alla validità dell’approccio laboratoriale. Per rispondere alla prima domanda, sono stati confrontati i dati numerici dei compiti di verifica somministrati ad entrambi i gruppi. Per soddisfare la seconda domanda, sono state visionate le risposte di due questionari, uno per insegnanti di Scienze e uno per genitori. Le attività laboratoriali hanno permesso al gruppo sperimentale di ottenere risultati migliori rispetto al gruppo di controllo, sebbene il divario dei livelli di apprendimento finali raggiunti, dalle due classi, non sia particolarmente ampio. Inoltre, la maggioranza sia degli insegnanti di Scienze sia dei genitori ritiene più utile il laboratorio al fine dell’apprendimento, poiché favorisce la memorizzazione. La ricerca ha evidenziato che le attività sperimentali facilitano in misura maggiore la comprensione e il ricordo dei concetti nel tempo, nonostante sia proficua anche la lezione frontale, in un’ottica di integrazione.

Abstract
The paper introduces an educational path on mineral fresh water, in two fourth classes of a primary school. The specific contents refer to the awareness of fresh water as the first food for human and the daily practices to save it, even to protect animal species of freshwater ecosystems. Within one of the two classes, the experimental group, a pratical – laboratory teaching approach was used, with scientific experiments; in the second class, the control group, a frontal approach was used, which involved the direct transmission of the contents. The main goal is to detect whether the laboratory approach is more effective than the frontal approach, for understanding the concepts. It is also intended to capture opinions of primary school science teachers and parents of pupils, regarding the validity of the laboratory approach. To answer the first question, the numerical data of the verification test, of both the groups, were compareted. To satisfy the second question, the answers of two questionnaires were viewed, one for science teachers and one for parents. The laboratory activities allowed the experimental group to obtain better results than the control group, although the gap in the final learning levels, achieved by the two classes, is not particularly large. In addition, the majority of both science teachers and parents consider the laboratory more useful for learning, because it promotes memorization. The research shows that experimental activities facilitate, in greater way, the understanding and memory of concepts over time, although even the frontal lesson is profitable when integrated.| File | Dimensione | Formato | |
