By legislative action in June 1958, the Commonwealth of Puerto Rico initiated a program to teach English as a second language to Spanish-speaking migrant workers. The purpose of the program is to improve employer-employee relationships and to help the agricultural migrant adjust to the English-oriented community when he is seasonally employed in the continental United States. Formal classes (vocabulary and language patterns), orientation periods (local laws, current events, consumer education), and recreational activities (games, sports, visits) are the 3 phases of the program. Lessons are divided into 3 groups providing for varying degrees of knowledge of English. Procedures for teaching including use of audiovisual aids are included. (JH)
