Good evening,

Here's my proposal:

You can talk about the cell phone. If they are children (CM1, CM2), the telephone function is reassuring for parents who can call their child at any time. These parents believe they know where the child is and what he or she is doing. 

College students use their cell phones to play and call their friends. The SMS function is preferred as well as the photo function.

It is a playful tool, used instinctively to feel connected to others (wandering on the Internet for example). It gives the impression of not being alone and avoids anxiety for the child who finds himself alone at home at the end of the day after a day of school for example. Television also played this role of "nanny" but the most of the laptop is the interactive and relational aspect.

The mobile phone changes the ways of thinking, learning, understanding the world and others, building one's identity: the list could be long.

In particular, the playful, sensory and motor aspect (because you simply need your eyesight, your hearing and your finger) allows you to access the information very quickly, to the other... effortlessly and without making deductive thinking work. The consequences are obvious in the classroom: rapid demobilization in the face of the effort to be made, difficulties in making links between knowledge or experiences in class, instability of attention, difficulties of concentration, disinterest in abstract knowledge (not related to the daily life of the young person), etc.

I hope I was able to help you, feel free if you have any questions :)
