Pratica didattica e caratteristiche dei docenti universitari che utilizzano Flipped Classroom
2020
La ricerca affronta il tema della pratica della Flipped Classroom (FC o classe capovolta) all’università, con un’attenzione particolare alla figura del docente e mira a definire le caratteristiche che accomunano i docenti che utilizzano questo metodo e come costoro percepiscono il loro ruolo. La metodologia di ricerca utilizzata è il metodo misto dello studio esploratorio sequenziale. Nella prima fase sono state condotte 20 interviste online in profondità con docenti italiani, spagnoli e britannici. Nella seconda fase è stato somministrato un questionario strutturato a 311 docenti dell’Università di Palermo, costruito partendo dai risultati ottenuti al termine della prima fase. I risultati …
La flipped classroom come strumento di inclusione
2017
La ricerca, svolta presso l’Istituto Professionale Economico e per il Turismo “Don Luigi Sturzo” di Bagheria (PA), ha previsto una fase preliminare durante la quale, per 12 docenti, è stato avviato un percorso formativo sulle modalità di progettazione di attività flipped. Successivamente le attività, costruite a partire dai contenuti disciplinari di Economia Aziendale, Francese, Matematica, Italiano, Storia, Educazione Fisica, Inglese, Geografia sono state proposte a 124 studenti di 7 classi con la modalità flipped. Secondo gli insegnanti, l’innovazione didattica ha fatto migliorare negli alunni la motivazione ad apprendere e la capacità di autoregolare il proprio apprendimento. The researc…
Flip-angle measurement by magnetization inversion: Calibration of magnetization nutation angle in hyperpolarized 3 He magnetic resonance imaging lung…
2010
The aim of this work was to establish a new, fast, and robust method of flip-angle calibration for magnetic resonance imaging of hyperpolarized 3He. The method called flip-angle measurement with magnetization inversion is based on acquiring images from periodically inverted longitudinal magnetization created using the spatial modulation of magnetization technique. By measuring the width of the area where the magnetization was inverted by the spatial modulation of magnetization preparation in phase images, the flip angle can be generated using a simple equation. To validate and establish the limits of the proposed method, flip-angle measurement with magnetization inversion acquisitions were …
MRI of inner ear fluids using modified GRASS sequences: a useful tool in the assessment of the normal and pathological labyrinth
1995
MRI is acquiring a progressively more important role in the investigation of petrous bone disease. Nevertheless, despite the extensive use of MRI in the detection of inflammatory or neoplastic involvement of the seventh and eighth cranial nerves, conventional spinecho images cannot be considered the modality of choice in inner ear imaging “Steady-state sequences” are known to be motion sensitive. By setting a very short repetition time, a large flip angle and a long echo time, one can obtain a sequence sufficiently sensitive to the slow movement of endo- and perilymph. We report our experience in MRI of normal and pathological inner ear with modified GRASS sequences.
Teaching Technology Usage in the ENT Medical Subdomain via a Flipped Classroom Approach
2018
The flipped classroom approach is supporting a continuous interaction of students and instructors via online communication and strengthens the ability to solve problems by self-organization. This is especially important in medical domains, like the one of ENT-Head/Neck (ENT: Ear-Nose-Throat) surgeries and treatment. Surgical corrections of the nasal airways, like FESS (Functional Endoscopy Sinus Surgery) or in the field of plastic surgery, are the second frequent surgical interventions in otorhinolaryngology. They have to be prepared very carefully and airflow simulation with Computational Fluid Dynamics (CFD) is gaining importance for diagnostics here. New in silico procedures, like imagin…
In-vitro-Untersuchung von biologischen und technischen Herzklappenprothesen im MRT: Beurteilung möglicher Anziehung und Erhitzung der Implantate
2000
PURPOSE In vitro evaluation of possible deflection and heating of present-day prosthetic heart valves during MR imaging at 1.5 T. METHODS 17 prosthetic heart valves, 12 technical and 5 biological, were investigated using a 1.5 Tesla Siemens Vision system. Deflection was measured at the edge of a 1.5 Tesla superconducting magnet. Each valve was then submerged in a vial of a 1/1 electrolyte solution and temperature was measured before and after imaging with a turbo-spin-echo sequence (TR 5200 ms, TE 138 ms, Flip angle 180 degrees, acquisition time 10.5 minutes, length of echo train 29). MR imaging was performed with phase encoding parallel and perpendicular to the plane of the valves. RESULTS…
Kontrastmittelgestützte 3D-MR-Angiographie der Becken- und Beinarterien mit automatischer Tischverschiebung bei 1,0 Tesla
2000
PURPOSE Assessment of the value of contrast-enhanced MR angiography (ceMRA) using an automatic tracking technique at 1.0 Tesla in comparison with digital subtraction angiography (DSA) of the pelvic and lower limb arteries. MATERIALS AND METHODS In 15 patients with peripheral arterial occlusive disease a ceMRA (3D FLASH, TR/TE = 6.2/2.3 ms, Flip angle alpha = 30 degrees, Matrix 170 x 256) using a new automatic tracking technique was accomplished. The reference method was DSA. Twenty-one vessel segments of each patient were graded as normal, stenosed (> 50%) or occluded. Image material was evaluated independently by two radiologists. RESULTS In comparison, the interobserver agreement showed a…
iTunes U: sperimentare la flipped nella formazione iniziale degli insegnanti
2017
La flipped classroom è un ribaltamento del tradizionale metodo didattico: ciò che veniva fatto in aula e a casa viene capovolto. Di fatto la flipped è una modalità blended che sfrutta tutte le potenzialità dei dispositivi mobili, le competenze e le attitudini delle nuove generazioni di studenti. Vi è uno spostamento dell’attenzione sullo studente, che è al centro del processo di insegnamento-apprendimento; di conseguenza il tempo in aula viene ripensato per esplorare gli argomenti in modo più approfondito e per creare opportunità di apprendimento più ricche. Il percorso di ricerca si articola in due fasi: la prima fase si è realizzata e conclusa nell’a.a. 2015-16 e la seconda fase si svolge…

Autoefficacia e resilienza del docente universitario
2023
In the field of university teaching, many research highlights that the role of the university teacher acquires a different connotation than the traditional model, assuming today the function of guide, accompanist, facilitator and mentor (Kim, Khera & German, 2014; Sultan, 2018). The research aims to provide theoretical references on the quality of teaching in universities and teacher training, to improve it, in a research report agile stimulating interpretation of results, useful within a TLC (Teaching and Learning Center). Taking about the recent results of the reference literature, we want to verify if the effectiveness of innovative teaching interventions (Flipped and Service Learnin…
