“DISCIPLINARY ORIENTIRING” AT SCHOOL

2014

The vocational development consists of helping the pupil to move his/her first footsteps in the real exercise of freedom, respecting the different stages of his/her development, so that he/she consistently act according to ethical principles and progresses in the correct direction to find an access to new degrees of freedom and responsibility. In the Academic Years 2011/2012 and 2012/2013 six high school teacher councils of year 4 classes in Palermo have been involved in the project Aracne. Thanks to the collaboration of experts and researchers, they have experimented a vocational development training, through the learning of the disciplinary contents, in order to develop students’ essentia…

Valutare i cartoni animati. Un'attività di formazione dei futuri insegnanti della Scuola dell'Infanzia

2008

Il contributo presenta la progettazione e realizzazione di un intervento formativo la cui finalità è stat quella di far riflettere gli studenti universitari, di Scienze della Formazione Primaria di Palermo, sulla fondamentale importanza di una valutazione adeguata e valida, quale condizione indispensabile per un efficace lavoro educativo. Inl particolare si è focalizzata l'attenzione sulla capacità di formulare giudizi adeguati, utilizzando indicatori per la valutazione dei cartoni animati trasmessi in tv e destinati a bambini della prima infanzia.

MIND, BRAIN AND MEDIA EDUCATION. A Research Project on Cartoons with Teachers and University Students

2017

The paper proposes a reflection on the educational dimension of cartoons from the double point of view of Media Education and Neuroeducation. Cartoons are either a means to highlight the educational potential of the fictional fruition practice and an activator memory, attention, emotion and perception which are at the basis of cognition and learning. This contribution describes an education research carried out in the A.Y. 2015/2016 with 12 in-service teachers and 198 university students attending the course of Primary Education Sciences at the University of Palermo. They both experienced a media education training methodology mediated by the use of cartoons

Cartoons di qualità nella prima infanzia. I bambini e la media education

2014

I bambini, già dall’infanzia, amano e utilizzano i media. È utile, quindi, educarli ad un uso corretto dei prodotti mediali al fine di insegnare loro a comprenderne il linguaggio e valutarne i contenuti in maniera autonoma e responsabile. I media, pur avendo una loro maggiore o minore predisposizione a determinate valenze educative, sono degli strumenti, delle opportunità, la cui significatività e la cui pregnanza educativa dipende, in larga misura, dal modo in cui essi vengono usati. La scuola è chiamata ad assolvere l’importante compito di promuovere negli alunni le competenze necessarie per divenire fruitori ed interlocutori attivi dei media: entra qui in gioco la media education. Promuo…

Experimental results from Al/p-CdTe/Pt X-ray detectors

2013

Recently, Al/CdTe/Pt detectors have been proposed for the development of high resolution X-ray spectrometers. Due to the low leakage currents, these detectors allow high electric fields and the pixellization of anodes with the possibility to realize single charge carrier sensing detectors. In this work, we report on the results of electrical and spectroscopic investigations on CdTe diode detectors with Al/CdTe/Pt electrode configuration (4.1×4.1×0.75 and 4.1×4.1×2 mm3). The detectors are characterized by very low leakage currents in the reverse bias operation: 0.3 nA at 25 °C and 2.4 pA at -25 °C under a bias voltage of -1000 V. The spectroscopic performance of the detectors at both low and…

Character Education and Children’s Literature. An Opportunity to Experiment Innovative and Reflective Teaching.

2016

Discussion focuses on how literature can be brought into the curriculum in helping to develop character traits in a meaningful, substantial manner. The book examines also how using the flipped classroom model provides opportunities to design and deliver courses using active learning and engagement strategies to facilitate students’ teamwork, problem solving and critical thinking skills in a collegial environment.

Incomplete Charge Collection at Inter-Pixel Gap in Low- and High-Flux Cadmium Zinc Telluride Pixel Detectors.

2022

The success of cadmium zinc telluride (CZT) detectors in room-temperature spectroscopic X-ray imaging is now widely accepted. The most common CZT detectors are characterized by enhanced-charge transport properties of electrons, with mobility-lifetime products μeτe > 10−2 cm2/V and μhτh > 10−5 cm2/V. These materials, typically termed low-flux LF-CZT, are successfully used for thick electron-sensing detectors and in low-flux conditions. Recently, new CZT materials with hole mobility-lifetime product enhancements (μhτh > 10−4 cm2/V and μeτe > 10−3 cm2/V) have been fabricated for high-flux measurements (high-flux HF-CZT detectors).…

Preliminary Analysis on Correlations between Spatial Distribution of Chlorophyll-a and Experimental Data of Biomass in the Strait of Sicily

2010

This study, using both remotely sensed and measured in situ data, is directed to the analysis of the correlations between the chlorophyll-a concentration and the biomass of sardines and anchovies acoustically evaluated in the Strait of Sicily. This work, inter alia, shows the usefulness of remote observation of seas in determining possible relationships between fish stocks and some oceanographic parameters (Sea Surface Temperature, Chlorophyll-a, Zooplankton).

Measurement of the radiation energy in the radio signal of extensive air showers as a universal estimator of cosmic-ray energy

2016

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8±0.7(stat)±6.7(syst) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principles calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the d…
