This report describes the background, organization, design, evaluation, and recommendations of a demonstration project involving a model preschool for 3- to 4-year-old children learning English as a second language (ESL). The impetus for the project was the increase in the number of immigrant children in British Columbia. Objectives were to develop and implement a preschool program specifically designed to meet the needs of ESL children and to assess the program's value as a prototype for serving ESL preschool children. In the program developed, one teacher met with morning and afternoon classes of 15 children. Curriculum is discussed in terms of goals, orientation of children and parents, daily schedule, physical setting, monthly planning, concepts taught, and strategies used to expand children's ESL skills and awareness of their own and other cultures. The research component of the project included a study comparing children's effectiveness in peer interaction with their English-language abilities; a study comparing the classroom behavior of a class of children relatively proficient in English with a class of less-proficient ESL users; and a parent component that informally examined relations between home and preschool. Program evaluation was conducted by a university professor who observed both morning and afternoon groups. Recommendations for ESL preschools address general issues as well as initial procedures and orientation, program planning, classroom preparation, parent involvement, and administration. (CB)
