The use of cellphones in the classroom: Like or Dislike?

Hi everyone! So in one of my classes we talked about the use of cellphones in the classrooms, (for this, I will attach a very interesting website with a report about this subject at the end of this post).

Personally, I think that as teachers, we must have the use of cellphones controlled inside our classrooms because what would prefer? Your students using their cellphones behind your back or maybe in front of you whil you are talking? Or perhaps to use the cellphone in various activity and take advantage of this technologycal devise? I would defenitively go with option numer two, it is in our mind how to use in a didactic way things that the students find interesting or attractive right?

Like or dislike the use of cellphones?
