Anyone who seeks a college education will face some challenges. These include difficult projects, busy schedules and complex social situations. The new responsibilities of being an independent adult can be frightening. And for an international student, this experience can be even more intense. Over one million international students studied at the many colleges and universities in the United States last year. Many of them came from countries where English is not the native language. But language was not the only barrier they faced. ELS Educational Services is a company that operates several centers at colleges across the U.S. These centers help international students improve their English. In February, ELS researchers presented a study at the yearly conference of the Association of International Education Administrators. This study collected the opinions of 662 international students at 23 different U.S. colleges and universities. Many expressed concerns about their relationships with professors. More than a third said they wished their professors would provide additional helpful criticism. Thirty-three percent wished professors would try harder to understand the international student experience. And 28 percent of the students wished professors would provide non-U.S. examples in class materials.
