      Reading books and looking at pictures are great, but nothing facilitates(´Ù½ø) learning like travel, especially for teenagers. Not only do they get to see a world beyond their neighborhood, but they get to experience it, feel it, taste it, hear it and better understand the world around them.

    After nearly four decades in the classroom and traveling the world, Phyllis Duvall Bailey knew this perhaps better than anyone else.

      Becoming engaged in the work in AKA Sorority Inc. in the US, she worked to educate children on the United Nations. There was no doubt in Bailey's mind that the lessons would mean so much more if the students could see these things for themselves.

      Starting in 2015, Bailey, 82, set out to take her students to the UN headquarters in New York City to give them a “Window Seat to the World”£¬ and thus transformed them into global citizens.

Indeed, it is a great opportunity to give students national and international exposure. Since Bailey saw the students as future leaders, she was desperate to expose them to the UN, its mission, its agendas (Òé³Ì) and its supporting organizations.

        She decided to give  $10, 000 of her own money to pay for the late June trip, enough to take 10 students aged 14£­17 on a four­night stay in New York. There, they had guided tours of the UN headquarters and the New York City harbor.

      It was Quenyaun Payne's first trip to the city and Taylor Sappington's second. Payne, 17, is a senior at Mceachem High School in the state of Georgia, the US. Sappington, 15, is a junior at Therrell High School in Atlanta,  Georgia,  the US. Both said their visit to the UN was inspiring.

   “I like not only how countries are working together but they're focused on common goals like global warming and keeping peace£¬”Sappington said.

     Payne commented, “The trip was amazing. I'm so thankful Mrs. Bailey made it possible.”

    Actually, there are a lot of people grateful for the retired teacher's effort. The United Nations Association of Atlanta recently gave Bailey its Humanitarian Award, and the United Nations Association of the US awarded her with the National Education Award.

   But Bailey wasn't looking for recognition or even gratitude. Over those four days in New York, she'd already felt it and seen it in the eyes of those 10 teenagers, Payne and Sappington included, who made the trip.

         “It has been a real joy to get to see their reaction to new experiences£¬” she said.
