INCLUDED IN THIS DOCUMENT ARE THE RATIONALE AND OUTLINE OF THE "LINGUA PLAN," A BILINGUAL EDUCATION PROGRAM DEVELOPED BY THE STAFF OF THE GALTON INSTITUTE TO IMPROVE THE PRIMARY EDUCATION OF MEXICAN AMERICAN CHILDREN WHO ENTER KINDERGARTEN WITH LITTLE OR NO KNOWLEDGE OF ENGLISH. THE MAJOR PURPOSE OF PROJECT LINGUA IS TO DETERMINE WHETHER (1) CLASSROOM USE OF THE CHILD'S NATIVE LANGUAGE, (2) SPECIAL MATERIALS WRITTEN TO REFLECT MEXICAN AMERICAN CULTURAL VALUES, OR (3) A COMBINATION OF BOTH IS MOST EFFECTIVE IN RAISING THE LEVEL OF EDUCATIONAL ACHIEVEMENT OF SPANISH-SPEAKING MEXICAN AMERICAN CHILDREN. THE COMPARATIVE EFFECTIVENESS OF THESE DIFFERENT FACTORS WOULD BE TESTED THROUGH ACTUAL CLASSROOM TEACHING. PROCEDURES TO IMPLEMENT THE PLAN ARE DESCRIBED IN THIS DOCUMENT AND CENTER ON--(1) SELECTION OF CHILDREN AND TEACHERS, (2) IMPLEMENTATION (TEACHER TRAINING, CURRICULUM DEVELOPMENT), (3) EVALUATION, AND (4) DISSEMINATION OF FINDINGS. APPENDED ARE A REVIEW OF OTHER BILINGUAL EDUCATION PROGRAMS AND THREE BIBLIOGRAPHIES OF RECENT WORK IN THIS AREA, CHILDREN'S BOOKS IN SPANISH, AND LISTS OF SPANISH CLASSROOM MATERIALS.
