The curriculum guide for Ohio's secondary level programs in English as a second language (ESL) begins with background information on factors to consider in developing an ESL curriculum, including limited-English-proficient students' characteristics, the language acquisition process, skill areas to be covered, instructional goals for four major language skill areas (listening/speaking, reading/vocabulary, writing, and grammar), and techniques for integrating language skills. A section follows for each of the four skill areas, outlining specific skills and content areas to be developed at each of three levels (beginning, intermediate, and advanced), and suggesting classroom activities for each skill. The guide is intended as a resource for teachers and administrators, to be modified or expanded as appropriate in each school district. (MSE)
