Nowadays there are some students use cellphones to copy teachers’ lecture notes. They think that taking notes with cellphones instead of by the hand can save time, that can be used in studies.

    In my opinion, cellphones are either good nor bad. It depend on how we use it. We should make properly use of cellphones. Cellphones are much easy for us to copy notes and more convenient to search what we need. However, we should remember that cellphones in the classroom can lead to lazy.
