This paper is a description of an Individualized Bilingual Instruction (IBI) program which was nationally validated by the U.S. Department of Education and listed in their directory of "Educational Programs That Work." It provides information on the technology of the IBI program, the type of curriculum selected and how the staff was selected and trained, as well as information on teaching methods and classroom organization. This discussion includes instructional elements that relate particulary to the bilingual/bicultural needs of the children served and more general instructional techniques adapted from other successful educational programs, many of which are not bilingual. These notions are discussed in the context of the following headings: (1) history of the IBI program, (2) how the IBI curriculum and training model evolved, (3) key elements in the program, and (4) program elements related to specific issues in bilingual education. A final section is devoted to a description of a longitudinal evaluative study of the program, a parallel program arrangement in Washington state and Texas. (Author/AMH)
