"Although excessive screen time is often frowned upon, language experts say that watching shows in a foreign language -- if done with near obsession -- can help someone learn that language. "These stories are hugely common," said Melissa Baese-Berk, associate professor of linguistics and director of the Second Language Acquisition and Teaching program at the University of Oregon. She points to a New York Times story about professional baseball players from Latin America who learned English by watching "Friends" with Spanish subtitles. But they didn't just watch "Friends"; they watched it over and over again. Philadelphia Phillies shortstop Freddy Galvis told the Times that he had watched every episode of the 10-season show at least five times. Stephen Snyder, dean of language schools at Middlebury College in Vermont, said this story sounds familiar to him. "Our Japanese classes are full of Chinese students and American students who grew up watching Japanese anime, and without having any formal training in Japanese, their comprehension is quite reasonable," he said. "It's a transnational phenomenon, and it makes sense." Baese-Berk says science supports what these young people have experienced. Studies show that it's best to acquire a language through both active and passive learning, and watching shows in a foreign language involves both. Trying to figure out a word that a character in a telenovela is saying would be an example of active learning, and admiring the character's outfit while hearing Spanish in the background would be an example of passive learning, she said."
