Firstly, technology and smart phones play an important role in our behavior right now. It is really essential to teach our children how to use smart phones.
In my opinion, I disagree that children can have there mobile phones and use them during school time because their phones can grab there attention and decrease there concentration. Furthermore, it would increase the number of bullying and cyberbullying around the students.
Some students hold there smart phones and i pads at the school, while they have classes and activities they must attend all of them, so when they have there mobile in the lessons. It can distribute their attention than focusing on their studying and their teachers.
Also, they need to study very well and listen carefully to what there teachers say and write every point that really important in the exams. As the result of using phones it can tough to pass and get high grades in their final tests.
Most of us right now suffering from bullying and cyberbullying as well. The teenagers use some bad words and hate speech while taking each others. For example, you can see there comments on their posts on social media taking about racism. Moreover, they are make fun of other people who has a different color or body especially that people hunted by obesity.
Furthermore, some of teenagers utilize their cell phones to bother their colleagues and their teachers by scamming calls to blackmail them.
Finally, I am against that because smart phones have a bad impact on our students and their career.
