smart phones in class are bad because they can desconcentrate teachers and students. students might chat in class and that isn`t good. maybe for teacher they will be more helpful because they can use them to find something or use the calculator. also now some smart phones have memory for Word documents.
smart phones can be very useful if people know how to use them.

cellphones are devices that now are very important to people.smart phones in class are useful because you can use the calculator or the Internet when you don`t find something in the dictionary,and also take pictures of something they didn`t copy in class. but students won`t have to use the cellphones to chat or contact people in classroom.
