This would depend on which side you are on, so if you are on the side allowing students to text at school, you can say it opens resources for students as well as a source of communication. However, personally I think that the argument that students shouldn't text would be easier because it has more evidence. You can say students can cheat, they can get distracted which will lead to bad grades etc
It is obvious the first question would be what is the text about,what does the author try to convey and how does he presents the facts to manage his goals.
