Improved time-resolved acousto-optic technique for optical fiber analysis of axial non-uniformities by using edge interrogation

2015

The time-resolved acousto-optic technique demonstrated recently to be a very useful method for the analysis of fiber axial non-uniformities, able to detect variations of fiber diameter in the nanometric scale with a spatial resolution of few cm. An edge interrogation approach is proposed to improve further the performance of this technique. The detection of subnanometer fiber diameter changes or sub-ppm changes of the core refractive index is demonstrated.

Radiation tolerant fiber Bragg gratings for high temperature monitoring at MGy dose levels

2014

International audience; We report a method for fabricating fiber Bragg gratings (FBG) resistant to very severe environments mixing high radiation doses (up to 3 MGy) and high temperatures (up to 230 degrees C). Such FBGs have been written in two types of radiation resistant optical fibers (pure-silica and fluorine-doped cores) by exposures to a 800 nm femtosecond IR laser at power exceeding 500 mW and then subjected to a thermal annealing treatment of 15 min at 750 degrees C. Under radiation, our study reveals that the radiation induced Bragg wavelength shift (BWS) at a 3 MGy dose is strongly reduced compared to responses of FBGs written with nonoptimized conditions. The BWS remains lower t…

E-portfolio e flipped classroom: un’indagine esplorativa con i futuri insegnanti di scuola primaria

2023

Il contributo intende far riflettere sul tema della formazione dei futuri insegnanti di scuola primaria, a partire dall’impiego dell’e-portfolio come dispositivo innovativo per promuovere l’acquisizione della competenza riflessiva e autovalutativa all’interno della flipped classroom. La ricerca, che ha coinvolto 154 studenti del Corso di laurea magistrale in Scienze della Formazione Primaria dell’Università degli Studi di Palermo, che frequentavano il corso di Docimologia nell’anno accademico 2020/2021, presenta i presupposti teorici, gli obiettivi e le modalità operative di un percorso che ha visto l’impiego dell’e-portfolio nella flipped per promuovere lo sviluppo delle competenze docimol…

The study aims to reflect on the training of future primary school teachers by starting from the use of the e-portfolio as an innovative tool to promote the acquisition of reflective and self-evaluation competence within the flipped classroom. The research involved 154 students of Primary Education Master’s Degree Course of the University of Palermo attending to the Docimology course during the academic year 2020/2021. This paper presents the theoretical assumptions objectives and operating methods of a path that made the use of the e-portfolio in flipped classroom to promote the development of docimological skills in higher education. It was hypothesized that the training intervention designed according to the principles of the flippmethodology and through the use of the e-portfolio would have contributed to the development of students’ self-evaluation skills during the 30 hours of the Docimology course.Settore M-PED/04 - Pedagogia Sperimentale
