Maria Guida is a researcher at INDIRE, a public research institute whose main mission is to sustain the evolution of the Italian educational system through technology-enhanced teachers training, system actions for improvement and innovation. At INDIRE Maria has had an active role in teacher training National Programs (i. e. the mandatory training programs for Newly Qualified Teachers). She collaborated with the University of Florence too, as a tutor for Mathematics and Physics postgraduate students in the TFA, the specialization course for soon-to-be teachers. She has been working for years (2007 onward) in the research “Immersive Education”, which investigates 3D virtual environments and their educational potential. At European level she is involved in STEM education with a focus on the active and student-centered learning, which she has driven for years her research to, because she could identify it, through studies and experiences, as an element of strong contrast to the dropout phenomenon.
