very true, am sure the challenges that teachers face may be:
1. abuse of the technology such as using it to watch pornography
2. using to communicate to boy friends/girlfriends/sugar daddies/sugar mummies, parents etc etc etc instead of using it for learning purposes
3. driving the leaners attention away from concentrating on studies
Such behaviors force schools to ban use of cell phones in schools. Otherwise use of technology in schools is very good and can assist learners to widen their knowledge.
If am not mistaken, a study was done by late Mr. J Milner from Centre for Social Research on the use of cellphones in schools. Unfortunately I do not have a copy of the study. He did it with a certain white lady. Try o find out from CSR in Zomba.
