Smart devices for students.
ALthough is very common to find students using their smart devices for personal reasons, students spend most of the time using these devices for entertainment purposes. Not really for academic purposes.
This technology can improve students’ lives. However, if the student is not really committed and is not under the supervision of the school teachers, it is complicated to affirm that the devices are really serving academic purposes.
These devices have the potential to be great learning tools. But teachers have to make a great effort to instill a new academic attitude in the student's behavior. Less entertainment and games; more research and homework.
This is not an easy task. Students are so used to playing games on these devices and to spend most of the time on social media, connecting and chatting with friends.
So schools are facing a major challenge. To change the culture and behavior of students regarding technology. If they can do that, then, we indeed could say that smart devices can be excellent tools to improve learning.
