Article: Dr charlotte Uhlenbroek recently returned to London after filming her second series, Jungle. It was difficult, 19-week trip, during which she explored the rainforests of Borneo, the Amazon and Congo, travelling around using variety of means of transport, including hot-air balloons and canoes. "I'm interested in the way animals communicate with each other. It was sometimes dangerous making the program ---I even went swimming with piranha fish. But the worst thing was insects. On one occasion I had 70 sand-fly bites on my arm. Luckily I didn't get sick. I prefer not to take tablets every day, but if I get a fever, take some medicine immediately." Filming the series was exciting, but also frightening at times. Her most challenging experience was climbing a 100-meter tree in Borneo, as she has a great fear of heights. "I had to keep pulling myself further and further upwards. All I wanted to do was get down again. Suddenly the safety equipment didn't look very strong and I thought that my ropes would break and I would crash to the ground." What did she enjoy most about returning to London? "When I've been away in hot uncomfortable conditions for a long time I dream about an ice-cold drink and my bed at home! But the thing I look forward to the most is nice long showers. There wasn't much water in some of the places we visited and I worried that I was using it all up and not leaving any for my colleagues on the camera team! "

Article: President Barack Obama has complained about the loss of privacy that comes with being leader of the United States, regretting the loss of simple pleasures such as a long walk or a trip to the car wash or supermarket. "I just miss - I miss being unknown," he said. "I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks. I can't take a walk." His dream, he said, was to "go through Central Park and watch folks passing by ... spend the day watching people - I miss that". Faced with criticism for playing more golf than most previous occupants of the White House, he explained that the sport was simply the best way of getting relaxed. " _ 's the only excuse I have to get outside for four hours," he toldHearstmagazines.

Article: Providing small classes for at least several grades starting in early primary school gives students the best chance to succeed in late grades, according to groundbreaking new research from a Michigan State University scholar. The research by Spyros Konstantopoulos, a professor of education, is the first to examine the effects of class size over a period and for all levels of students. The study appears in the American Journal of Education. He is also a member of a group for the Department of Education's Instiute of Education Sciences that will give official advice on class size to the states. He said the advice will mirror his research: the best plan is to provide continuous small classes(13 to 17 students) for at least several years starting in kindergarten or first grade. "For a logn time states thought they could just do it in kindergarten or first grade for one year and get the benefits," He said. "I don't believe that. I think you need at least a few years in a row where all students, and especially low-achievers, receive the treatment, and then you see the benefits later." His research used data from the Project Star study in Tennessee that analyzed the effects of class size on more than 11,000 students in primary and middle school. He found that students who had been in small classes from kindergarten through third grade had actually higher test scores in grades four through eight than students who been in larger classes early on. Students from all achievement levels benefited from small classes, the research found. "But low-achievers benefited the most, which narrowed the achievement gap with high -achievers in science, reading and math, " he said. Although the study didn't consider classroom practices, he said the reason for the narrowing gap is likely due to low-achieving students receiving more attention from teachers. " _ is especially important in poorer schools because teacher effectiveness matters more in schools with more disadvantaged and low-performing students, " he said.
Answer: the size of the class
