There are language barriers, too.
Roy Louli fled Syria with his family last year. The 10-year-old enjoys playing brännboll, a sport similar to baseball, during recess, but says he has struggled to make any German friends.
The refugee students in Dürolf and Korn's classes, though, try to help each other.
Another student, Ahmad Al-Sabahi, performed well enough to enroll in a regular class, filled with native German speakers. With the greater exposure to local children, the 11-year-old, unlike Louli, has made some friends there.
As refugee students work to overcome social isolation in school, private groups, such as Visions for Children e.V
, a Hamburg-based organization, are stepping in to provide cultural competency training to teachers to help avoid communication gaps and misunderstandings.
