The report describes a federally funded project for the development of an innovative approach to bilingual curriculum and instruction and inservice teacher training. A needs assessment and research process resulted in development and field testing of a set of bilingual Spanish-English instructional materials for limited-English-speaking urban middle school students and related materials for teacher training and support. The materials included a bilingual textbook on the history and geography of California, a series of student worksheets, and a teacher's guide to classroom activities coordinated with the textbook. The teacher training component consisted of a series of workshops addressing issues in bilingual education and the use of the materials developed. The final project report details the process by which these tasks were completed, in two phases, and the field testing of the instructional materials with 204 students in one school district. Practical recommendations are made for use of the program and materials in other settings. (MSE)
