PARTNERSHIP FOR TRAINING. GENITORI, DOCENTI E DIRIGENTI: LA COMUNITÀ CHE EDUCA
2022
Questo contributo si basa sul bisogno di lavorare sulla corresponsabilità tra la scuola e la famiglia. Questo scopo è sviluppato dal presupposto che un crescente interesse su una scuola di qualità comporta la costruzione di alleanze significative. Costruire un “patto” comune tra queste due importanti agenzie educative significa incrementare un globale e significativo sviluppo degli studenti. La teoria ecologica dei sistemi spiega come il bambino, nel suo cammino di maturazione bio-psico-sociale, è costantemente influenzato da sistemi differenti ed interdipendenti, che simultaneamente esercitano la loro influenza sul bambino. In vista di tale naturale interdipendenza l’alleanza scuola-famigl…
Partnership for training. Parents, teachers and leaders: the educating community
2021
Family and school are the educational agencies that play a primary role in the child development. Therefore, an educational partnership based on values and responsibilities sharing and on the mutual respect of competences is necessary. This idea is reflected in Bronfenbrenner (1979; 2001), Epstein (2018), Eccles and Harold (2013) theoretical/methodological models and in the Pati (2019) pedagogical-epistemic reflection. Starting from this theoretical framework, it is considered necessary to investigate the point of view of teachers, parents and managers in order to provide a clear vision of the practices of educational co-responsibility in reference to the Italian school context. We predicte…

Six-dimensional measurements of trains of high brightness electron bunches
2015
Trains of ultrashort electron pulses with THz repetition rate, so-called comblike beams, are assuming an ever growing interest in plasma-based acceleration. In particle-driven plasma wakefield acceleration (PWFA), a train of driver bunches with separation of the order of plasma wavelength, i.e., 300 μm, resonantly excites a plasma wake, which accelerates a trailing witness bunch, injected at the accelerating phase. Comblike beams have great potentialities in different fields of applications. In particular, radiation sources, such as free-electron lasers and THz radiation, take advantage from the possibility to tailor electron beams modulated both in time and energy, to customize emission ba…
Real-time observation of the charge transfer to solvent dynamics
2013
Intermolecular electron-transfer reactions have a crucial role in biology, solution chemistry and electrochemistry. The first step of such reactions is the expulsion of the electron to the solvent, whose mechanism is determined by the structure and dynamical response of the latter. Here we visualize the electron transfer to water using ultrafast fluorescence spectroscopy with polychromatic detection from the ultraviolet to the visible region, upon photo-excitation of the so-called charge transfer to solvent states of aqueous iodide. The initial emission is short lived (similar to 60 fs) and it relaxes to a broad distribution of lower-energy charge transfer to solvent states upon rearrangeme…
Thermoelectrics: From history, a window to the future
2019
Thermoelectricity offers a sustainable path to recover and convert waste heat into readily available electric energy, and has been studied for more than two centuries. From the controversy between Galvani and Volta on the Animal Electricity, dating back to the end of the XVIII century and anticipating Seebeck’s observations, the understanding of the physical mechanisms evolved along with the development of the technology. In the XIX century Ørsted clarified some of the earliest observations of the thermoelectric phenomenon and proposed the first thermoelectric pile, while it was only after the studies on thermodynamics by Thomson, and Rayleigh’s suggestion to exploit the Seebeck effect for …
THE ENVIRONMENT AS THE CHILD’S PRIMARY INTERLOCUTOR
2021
The environment organization is one of the Montessori pedagogy milestones which in recent decades has been revised by international scientific literature [1]. The environment organization is a primary interlocutor for the child [2] because, as Montessori says, the child "absorbs" and embodies it in himself [3]. This self-transforming work is a natural process that takes place spontaneously and it mostly depends on the experiences made in the environment, especially in the first years of life when the child's mind is predisposed to absorb a quantity of non-quantifiable information. In "Self-education in elementary schools", Montessori [4] even describes a "constant reaction" whereby, in cert…
Valutazione e personalizzazione a scuola: le prove oggettive di profitto
2022
La scelta delle modalità e degli strumenti di valutazione da impiegare con i propri allievi, in base a ciò che si vuole valutare e al perché, è uno dei compiti didattici dell’insegnante, la gamma di scelta è ampia; in questo intervento ci soffermeremo su alcuni aspetti connessi alla scelta e all’impiego di un tipo di prove per la valutazione del grado di conseguimento degli obiettivi di apprendimento previsti al termine di un’attività didattica, esse sono comunemente denominate prove oggettive di profitto volendo così sottolineare l’intento di ridurre il più possibile la soggettività dell’insegnante quando valuta i suoi alunni. The choice of assessment methods and tools to be used with your…
Promuovere e valutare le abilità di pensiero critico nella formazione iniziale degli insegnanti
2019
L'articolo presenta una ricerca che analizza e valuta un percorso di formazione dei futuri insegnanti di scuola primaria e dell’infanzia, per lo sviluppo delle abilità costitutive del pensiero critico durante il terzo anno del tirocinio universitario. Si è inteso conoscere gli esiti conseguiti da 200 soggetti, prossimi all’insegnamento nella scuola, quando pianificano e realizzano un intervento in classe, e quali possibili difficoltà incontrano nelle fasi di sviluppo dell’azione didattica programmata. La progettazione didattica è stata utilizzata dagli studenti sia come struttura sia come guida dell’azione, perché ha preparato la sequenza delle attività di insegnamento, ha anticipato l’orga…
Electron Irradiation Effects on Single‐Layer MoS 2 Obtained by Gold‐Assisted Exfoliation
2022
International audience; Mechanical exfoliation assisted by gold is applied to obtain good quality large lateral size single-layer MoS2. The effects of 2.5 MeV electron irradiation are investigated at room temperature on structural and electronic features by Raman and microluminescence spectroscopy. The exciton recombination emission in the direct bandgap of single-layer MoS2 is affected during irradiation starting from the minimum explored dose of 1 kGy. At higher doses, Raman bands show no relevant modifications whereas the exciton emission is quenched, suggesting that irradiation-induced point defects affect exciton dynamics.
