In progressing toward the development of adequate instructional resources for use by the schools to capitalize upon the unique strengths of children with Hispanic-heritage language and cultural assets, Southwest Regional Lab (SWRL) Research and Development has produced or is in the process of producing the following assessment and instruction systems: (1) The Planning Decision System, (2) The Diagnostic Assessment System, (3) The English Language and Concepts Program for Spanish-Speaking Children, (4) The Spanish Language and Concepts Program, and (5) The Spanish Language Reading Program. These programs, components within the framework of the SWRL Personalized Bilingual/Bicultural Education Model, provide the instructional resources for use by schools to insure that youngsters acquire proficiency in basic Spanish and English language skills requisite to success in Spanish/English elementary school instruction. Specific references are made indicating how cultural considerations are incorporated into the educational materials. (Author/AMH)
