This manual attempts to provide practical and useful linguistic information for classroom teachers and classroom aides in bilingual programs, K to 12. It stresses the importance of teamwork in any bilingual program, a team consisting of teachers, aides, volunteers and student tutors. The goal of the manual is to help teachers and aides become more effective in bilingual programs by means of the following objectives: (1) recognition of the positive advantages to the learner and society resulting from bilingual education; (2) awareness that to teach bilingually, one must first know: (a) what language is, (b) that language has rules, and (c) that language and culture are inseparable; (3) awareness of the various approaches to teaching/learning language in bilingual programs; (4) respect for the child's language(s); (5) recognition of available resources; (6) recognition that language is learned through experiencing, listening and speaking, prior to reading and writing; (7) recognition that initial instruction must occur in the learner's dominant language; and (8) recognition that language is in a constant state of change.
