Because of its undeniable benefits, I believe strongly in the use of personal electronic devices in education. In the first place, research, as well as education, can be used. You can download data, save time and money on paper books and store information and textbooks on the Internet. This makes your bags lighter but keeps more details. Second, these applications are not just entertaining, but also educational, with colorful courses, entertaining methods and attractive content. Finally, smartphone telephones allow students to communicate or relax by playing music or games if they are bored or tired of studying. I suggest enabling teachers in both classrooms and out-of-class learning to use these devices and encourage them.
