Let student think what should be done or needed to be. Student should try by themselves. If they come out with some useless or wrong answers by trying that would be great.
Ask your students about computer, some will say something about it, some will not, some will ask you to talk about it . You dont answer them, give them opportunity to try. Tell them to try to search by themselves. Do not force or pressure them ever. make them curious if you can and give them time. When they try they must ask questions to their parents or friends or other acquaintances. that is the sprite you are looking forward to. after few days you ask them again about computer or answer them.
