We've been learning how to write a persuasive text. This persuasive text is about our serial story, and how they've banned cellphones in school. We're writing if they should be banned.

Should Cellphones be banned in schools? 
 I believe cellphones should not be banned in schools. This will have facts about how useful cellphones are.

 Cellphones are convenient to have, for example, all cellphones are able to access the internet, They are just as helpful as other devices like laptops, etc you’ll get a wider access of information. they can research and go to websites to further help extend their work. This means that Another thing cellphones can be used for is to call for help in emergencies. They’d be able to call or dial 111 to report any emergencies. (Parents do provide cellphones to their child/ren for emergency usage.)

 If cellphones are permitted,There should be rules and responsibilities about the use of cellphone, (Like when and where cellphones can and cannot be used.) Schools could encourage PCs in classroom while encouraging cellphone usage out of classrooms. Of course students need to learn how to use cellphones responsibly. Student should know they shouldn’t use it to cheat on tests, cyberbully and many more… if necessary, teachers could have students put their cellphones on airplane mode. Making them unable to use the internet. or have them put it in the front of the classroom until it’s over. (But is a risk if an emergency occurs)

 In conclusion I think cellphones should be allowed in school. They’re just really helpful to have. It can be a lifesaver and are able to access a lot of information. as long as the student is responsible, there won’t be any harm done.

What I found difficult: Finding websites that aren't about why cellphones should be banned.
What I need to do next time: Put in the websites i used to research.
