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…
Using Prototyping in Authentic Learning of Human-Centred Design of Mobile Apps
2017
Recent advances in mobile technology have seen a sharp increase in the number of mobile applications across various application domains. The challenge remains that many software development teams may lack appropriate competences to design usable and human-centred interactive systems. This can negatively affect the usability and the user experience. In this article, we present how to learn the human-centred design process using an authentic learning approach. Students need to investigate, discuss, construct new knowledge and apply theoretical concepts to address real world problems. The main purpose of authentic learning as a pedagogical approach is to position the subject of study into a re…
Steady state shocks in accretion disks around a Kerr black hole
1994
Results of numerical simulations of shock solutions in a geometrical thin accretion disk around a Kerr black hole (BH) are presented. Using the smoothed particle hydrodynamics (SPH) technique, the influence of the central object is included by means of an effective potential, We first present the theory of standing shock formation in accretion disks around a Kerr black hole, and show that the results of our numerical simulation agree very well with the theoretical results. We find that the shocks in an inviscid flow are very stable. We also remove the ambiguity prevalent regarding the location and stability of shocks in adiabatic flows. Finally we sketch some of the astrophysical consequenc…
ICTV Virus Taxonomy Profile : Finnlakeviridae
2020
Finnlakeviridae is a family of icosahedral, internal membrane-containing bacterial viruses with circular, single-stranded DNA genomes. The family includes the genus, Finnlakevirus, with the species, Flavobacterium virus FLiP. Flavobacterium phage FLiP was isolated with its Gram-negative host bacterium from a boreal freshwater habitat in Central Finland in 2010. It is the first described single-stranded DNA virus with an internal membrane and shares minimal sequence similarity with other known viruses. The virion organization (pseudo T=21 dextro) and major capsid protein fold (double-β-barrel) resemble those of Pseudoalteromonas phage PM2 (family Corticoviridae), which has a double-stranded …
Contextualized project-based learning for training chemical engineers in graphic expression
2021
Abstract This paper describes the planning of a computer-aided design (CAD) laboratory for training chemical engineers in graphic expression. The CAD laboratory was organised into four projects following a project-based learning method. Flipped classroom and contextualised learning were used to motivate the students and promote meaningful learning. The laboratory mainly focused on engaging the students by replicating 2D and 3D plans of common industrial engineering equipment and piping and instrumentation diagrams of industrial facilities. Two surveys carried out before and after the course showed that the student’s perception of their graphic expression skills significantly increased. Gend…
Addressing Student Motivation, Self-regulation, and Engagement in Flipped Classroom to Decrease Boredom
2016
The interplay teacher regulation and student self- regulation of learning is an important topic in contemporary theories of teaching and learning. The pervasiveness of the boredom experienced by many students, along with its deleterious effects, clearly implies that educators, and teachers responsible for the design of academic settings should pay more attention to this emotion. With regard to the prevention or reduction of boredom, the present findings suggest that specific measures could focus on increasing the perceived values of activities in achievement settings. This study used mixed methodologies, including a student perception inventory and observations, to investigate whether teach…
Observation of Spin Flips with a Single Trapped Proton
2011
Radio-frequency induced spin transitions of one individual proton are observed for the first time. The spin quantum jumps are detected via the continuous Stern-Gerlach effect, which is used in an experiment with a single proton stored in a cryogenic Penning trap. This is an important milestone towards a direct high-precision measurement of the magnetic moment of the proton and a new test of the matter-antimatter symmetry in the baryon sector.
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…
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 …
