Becoming a teacher who uses ICTs in the classroom is not a decision, it is a process. With this document I want to explain the trend in recent years has led me to use ICTs and electronic devices in the field of education. And from all of it this should lead us to rethink education in the XXI century. Some time ago, see the cellphone in the classroom, for me it was a problem and a headache. But today I see it as an essential and basic tool for the students, as in my case, ICTs have become essential for their education inside and outside the classroom. The other aspect that has completely changed the way I teach has been knowing and applying the methodology of the "flipped classroom", which as you will see I like the idea of reversed education or maybe better "flipped learning" .
