The Hawaiian Language Immersion Program, implemented at the kindergarten/first grade level in an elementary school on Oahu and one on Hawaii, is described and evaluated. The program was instituted at the request of parents of students who had attended a Hawaiian language immersion preschool and was open to all students, regardless of ethnicity or language background. Students received instruction in language arts, mathematics, and other content areas entirely in Hawaiian. Instructional assistance was provided by young professionals from a Hawaiian studies program and by parent and community volunteers. Lack of instructional materials was a significant problem. Evaluation of the program was based on ethnographic classroom observations, interviews with parents and school personnel, and oral language assessment of the students in Hawaiian and English. Evaluators found that the program had near total immersion, that students appeared to understand and respond appropriately to instruction in Hawaiian, that a range of topics and content areas were being taught, and that there was unusually high parent involvement and support. Almost all students had achieved moderate to high Hawaiian proficiency for their age, others were making significant gains in the language, and all were fluent in English conversational discourse. Twenty-two recommendations are made, including continuation of the program through grade 6 for participating students, and extension to a new cohort of kindergarten and first-grade students. A detailed account of the curriculum and instruction is included in the report. (Author/MSE)
