Problem: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Problem: Article: All young people dream of travelling the world. They are restless and very eager to see new sights. However, they have little idea how they would really do it if given the chance. Because their knowledge of geography is quite limited, they seldom know much about the places they wish to visit or how they would get there. Already hundreds of thousands of Chinese student tourists are visiting these places-Wuyi, Lhasa, Lijiang, Dali, Vientiane and Phnom Penh. Indeed, these students will soon be the most travelled generation in China's long history. The World Tourist Organization predicts that a quarter of a century from now the number of Chinese tourists going abroad will be twenty times what it is today. The largest percentage of these tourists will visit Southeast Asia. Not all Chinese who travel abroad will be tourists, however. More and more youths are deciding to volunteer their skills in this region; much like their peers in the Peace Corps and VSO. Critical thinking skills required include planning for a trip and solving problems after the trip has begun. The focus is on how to read an atlas to make travel plans and how to find ways of travelling. An atlas offers a wealth of information about geography and is one way to increase students' awareness of their global environment. Use of an atlas especially addresses the needs of students with different visual and spatial learning styles.
