When I visited, the room and the playground were full of fun, open-ended activity with the children using their native languages with each other. Everything in the classroom was labeled in Hebrew and Arabic. Computer games in both languages were available for the children to use. There was no heavy academic emphasis, merely an atmosphere of fun and harmonious interaction among the students and with the teacher. Once the children are in first grade, the teaching structure changes.
Children have a home room with two teachers, one Arab and the other Jewish.
They speak to the children in their native language. During the day there are different levels of language classes in Hebrew and Arabic, with children assigned to a group based on their ability. I visited a second grade advanced Hebrew class. Like in the kindergarten, everything was labeled in Hebrew and Arabic. One thing that was especially interesting was the transliteration of Arabic words into Hebrew letters so that Jewish children who cannot read Arabic script could learn the Arabic word.
