3．When most people talk of a classroom，they think of older people teaching younger ones．But when it comes to learning about high-technology devices，the opposite can often be true．That is what is happening through a program in the eastern American city of Columbia，Maryland．The 50Plus Center provides free technology classes for adults aged 50and older．The teachers are often teenagers and even younger children．
Myra Stafford is 73years old．She signed up for the workshop to learn how to use her iPad．Ms．Stafford says she is learning quickly about the device and that she enjoys learning from younger people．
Eleven-year-old Zhion Perkins teaches Ms．Stafford．He says，"You have to be really，really patient because some of them might not accept the knowledge as smoothly as others．"Meridy McCague，director of the 50Plus Center，says，"As people are aging，their worlds get a little smaller．Some of them can no longer drive； some of them don't get out to make long trips to visit their relatives．The program brings them back into Facebook and Skype．Now，they can do everything from ordering things from Amazon to ordering groceries or meals．Teaching senior citizens about technology can prove helpful for the economy．As seniors get more excited about using the technology，they're going into the market place and buying some products．So that's a boom in economy right there．"
Madison Lam is a 17-year-old teacher of the technology workshop．She says she also learns a lot from helping seniors．
Safire Windley is head of the Youth and Teen Center that operates the program．She says young people gain social skills from teaching older residents．This is something they need．
