A guide to the development of Spanish-language curricula for Spanish-speaking secondary students is intended to help teachers and administrators design programs building on students' existing language strengths. The recommended instructional approach is functional-notional, and local districts are encouraged to use it to adapt their textbooks and revise their programs to meet current student needs. The issue of providing specialized Spanish instruction within Spanish second language classes is also discussed. The first portion of the guide, intended for administrators, addresses administrative issues and is written in English. The remainder, designed for the classroom teacher, is written in Spanish. It addresses aspects of instruction, including theoretical bases, the application of theory, specific instructional objectives for each of three levels, program selection and placement, instructional methods and activities for each level, and adaptation of instructional materials. Appended materials include a list of linguistic functions and notions, an article on dialogue journals, a functional trisection of oral activity levels, and bibliographies of reference and instructional materials.
