L'espressione linguistica in italiano scritto di insegnanti in formazione
2012
Nel contributo sono presentati e discussi gli esiti di un intervento formativo, strutturato su specifici principi metodologici, per promuovere in 80 studenti del corso di laurea in Scienze della Formazione Primaria il livello di competenza linguistica in italiano scritto. I ragazzi sono stati guidati in attività di riflessione, di pianificazione ed elaborazione di testi; inoltre sono stati stimolati ad un’attenta definizione del campo delle intenzioni comunicative e delle modalità logico-creative necessarie alla realizzazione dell’espressione scritta. Per l’analisi e la verifica dei loro prodotti scritti sono stati utilizzati 14 indicatori; per favorire sistematici processi valutativi nei s…
Dire, esprimere, comunicare. Strumenti didattici per fare apprendere
2012
La conquista e il potenziamento della capacità espressiva, orale e scritta, sono obiettivi irrinunciabili dell’insegnamento scolastico, in direzione del dominio maturo della competenza linguistica. Per progettare e realizzare percorsi educativi efficaci a promuovere negli alunni le abilità linguistiche, espressive e comunicative, gli insegnanti utilizzano una varietà di strumenti e strategie che la ricerca, non esclusivamente didattica, ha reso loro praticabili nell’azione quotidiana. La questione è come scegliere e selezionare procedure metodologiche in grado di coniugare, in modo sistemico e sistematico, la dimensione autentica del soggetto-alunno con quella dell’apprendimento di conoscen…
Pensiero critico nei bambini di scuola primaria: che cosa e come valutare
2018
A scuola come nella vita le abilità di pensiero critico sono fondamentali; queste abilità riguardano soprattutto l’elaborazione integrata di informazioni, l’uso corretto di ragionamenti, la formulazione adeguata di giudizi, l’assunzione di scelte autonome e controllate. L’espansione tecnologica alimenta le difficoltà di bambini e ragazzi di organizzare, in modo coerente e logico, i dati conoscitivi provenienti da più fonti come pure di valutare informazioni e di servirsene. Non sempre a scuola sono previsti ed attuati interventi didattici, intenzionali e sistematici, che esercitano e favoriscono negli alunni abilità quali la generazione di idee originali, l’espressione di convinzioni person…
Aquatic Macrophytes Occurrence in Mediterranean Farm Ponds: Preliminary Investigations in North-Western Sicily (Italy)
2021
Mediterranean wetlands are severely affected by habitat degradation and related loss of biodiversity. In this scenario, the wide number of artificial farm ponds can play a significant role in the biodiversity conservation of aquatic flora. In the present contribution we show the preliminary results of a study on Mediterranean farm ponds of north-western Sicily (Italy), aimed to investigating the environmental factors linked to the occurrence of submerged macrophytes (vascular plants and charophytes). We studied the aquatic flora of 30 ponds and determined the chemical and isotopic composition of their water bodies on a subset of the most representative 10 sites. Results show that (1) farm p…
Determination of Cd, Co, Cu, Fe, Pb, Mn, Ni and Zn in diets: Development of a method
1991
A method useful for the determination of cadmium, cobalt, copper, iron, lead, manganese, nickel and zinc in diets is described. Organic matter is destroyed applying a wet procedure, and element content is measured by flame atomic absorption spectroscopy (FAAS) in the case of copper, iron, manganese, nickel and zinc, and by graphite furnace (GF-AAS) in the case of cadmium, cobalt and lead. The matrix interference study is carried out. Values found for linearity, detection and quantitation limits as well as accuracy show that the described method is useful to determine the elements taken into account at usual levels in diets.
Sense of coherence and health among home-dwelling older people.
2010
Sense of coherence (SOC) is important for maintaining health. The aim of this study was to investigate if the SOC experience among home-dwelling physically active older people differs from that of hospital patients with the same age and sex. Data were collected with questionnaires and structured interviews containing Antonovsky’s SOC scale in an age- and sex-matched study group (n=160). Non-parametric statistical analyses were performed. No differences were found in SOC between home-dwelling individuals and patients. Ninety-five percent of the home-dwelling individuals perceived themselves as being in good health and 42.5% among the patients (p<0.001). SOC and disease were predictors fo…
Preparation of 2,3-seco-5α-cholestane-2,3-diol and 4α-methyl-2,3-seco-5α-cholestane-2,3-diol and its reactions with o-nitrophenyl selenocyanate
1984
The reaction of 2,3-seco-5 alpha-cholestane-2,3-diol and 4 alpha-methyl-2,3-seco-5 alpha-cholestane-2,3-diol with o-nitrophenyl selenocyanate was studied. The diols were synthesized from cholesterol.
Investigating applicability of ratings of indicators of the CLASS Pre-K instrument
2022
When classroom observations are increasingly used for accountability and evaluation purposes, a deeper understanding of the psychometric properties of such measurement tools is needed. The present study took a unique approach to examine the psychometric properties of a commonly used classroom observation measure by testing the reliability of indicators for higher-order constructs (i.e. dimensions). We investigated the reliability of indicator ratings of the Classroom Assessment Scoring System (CLASS) Pre-K instrument in Finnish kindergarten and first grade classrooms. Twenty-one observer pairs rated 838 segments identified from the 413 lessons of 48 teachers. Variance components models were…
Do Investors Care About Noise Trader Risk?
2011
International audience; The link between investor sentiment and asset valuation is at the center of a long-running debate in behavioral finance. Using a new composite sentiment indicator, we show that the conventional risk does not explain the abnormal returns of portfolios most sensitive to the sentiment factor. Our result supports the existence of a sentiment risk valued by financial markets. We also find that the firms more impacted by the sentiment risk correspond to difficult-to-arbitrage and hard-to-value stocks, e.g. small stocks, growth stocks, young stocks, unprofitable stocks, lower dividend-paying stocks, intangible stocks and high volatility stocks.
