To ascertain the degree of utilization of bilingual programs and the concerns and questions teachers may have about their implementation, the Division of Bilingual and International Education of the Southwest Educational Development Laboratory conducted a study which had four objectives relating to implementation of bilingual education programs in Texas: (1) to develop a procedure for identifying types of programs being implemented in the field; (2) to determine teacher concerns about implementation of selected programs; (3) to determine levels of use of such programs; and (4) to draw conclusions to aid in staff development for such programs. The study involved use of the Concerns-Based Adoption Model (CBAM), designed to conceptualize and facilitate educational change, and had a primary goal of determining the potential applicability of CBAM to bilingual education programs, to develop a process that school districts could utilize to improve the effectiveness and productivity of their bilingual programs. Results indicated that with some modifications the CBAM system of instruments and procedures could provide schools or districts with diagnostic information to build prescriptive intervention strategies which can aid in adoption and implementation of bilingual education programs. Attachments include questionnaires and other instruments, computer coding instructions, and data from the study. (JD)
