THE DEMONSTRATED EFFECTIVENESS OF HEADSTART AND OTHER PRESCHOOL PROGRAMS IN EXPOSING DISADVANTAGED CHILDREN TO EXPERIENCES THAT DEVELOP LANGUAGE AND CONCEPTUAL GROWTH HAS LED TO A CALL FOR AN EXTENSION OF THIS PROGRAM INTO THE SEQUENTIAL SCHOOL YEARS. THIS PROSPECTUS SEEKS--(1) TO PROVIDE AN EXTENSION OF THESE EXPERIMENTAL PROGRAMS FROM KINDERGARTEN THROUGH THE SECOND GRADE, (2) TO PROVIDE FLEXIBLE GUIDELINES FROM WHICH SUCCESSFUL LANGUAGE EXPERIENCE PROGRAMS FOR SPANISH-SPEAKING PUPILS IN THESE GRADE LEVELS CAN BE DEVELOPED, AND (3) TO PERMIT AN EASIER TRANSITION FOR THESE PUPILS INTO THIRD GRADE. GUIDELINES ARE PROVIDED FOR THE SELECTION AND IDENTIFICATION OF PUPILS, TEACHERS, AND TEACHER AIDES, AS WELL AS SUGGESTED ACTIVITIES AND METHODS FOR DEVELOPING NECESSARY LANGUAGE SKILLS. APPENDICES INCLUDE LISTS OF CURRENT INSTRUCTIONAL MATERIALS, SELECTED REFERENCES, AND MULTIPLE LANGUAGE MEDIA PUBLISHERS AND DISTRIBUTORS. (DK)
