The Alaska State Operated School System (ASOSS) has now completed its second full year of experimental bilingual education. In an area where Yupik Eskimo is often the first and only language spoken by the native citizens, a decision was made to experiment with teaching the early primary grades in the Native language, introducing English as a Second Language (ESL) in small, manageable portions. To determine the validity of such an approach, an evaluation design was conducted over a 3 year implementation period. The 2 categories of instruments used for the evaluation were: (1) academic--Yupik literacy and numerical skills; (2) linguistic--acquisition of grammar and meaning in Yupik and English. The analysis procedure was the method of t-test for differences between independent group means. The statistical analysis results are presented in 3 sections: (1) literacy, (2) numerical skills, and (3) linguistic skills. In each section the results are generally described, followed by a brief discussion of the overall patterns as a whole. Program recommendations in the final section of the report concern: (1) instructional objectives, (2) English literacy, (3) math, (4) alphabet, and (5) creative writing. (FF)
