This collection of readings on teaching bilingual and bidialectal students, particularly the American Indian, the Spanish speaking, and the urban black, is divided into three sections, headed by a general overview of the problems. The first section deals with bicultural understanding; the readings are intended to help the teacher assess his own role, whom he teaches, what he teaches, and what he can teach. The second section is devoted to theories and experiments in multilingual communication and language learning. The readings in this section, which were selected to provide the teacher with a view of possible applications and approaches, range from general theoretical discussions to specific field surveys. The third and final section deals with practical applications of theories and techniques in actual school programs. A list of suggested reading concludes the volume. (Author/KM)
