Boy Meets Girl (1982)

Two doctors from Tel Aviv join 'Doctors Without Borders' and travel to Thailand to help out Cambodian refugees. They leave their daughter, Aya (aged 10) at a kibbutz where the children are housed by age, but not gender. Not only does she have to get used to dealing with a lot of children, making friends and enemies, she has to get used to sharing her room with boys. And sharing the showers with them too.
