The primary objectives of the New Nursery School were to increase children's sensory and perceptual acuity, develop positive self concept, and increase language, conceptual and problem solving abilities. During 1969-1970 the longitudinal study, begun in 1964, included 28 children who were 3- and 4-year-olds from lower socioeconomic homes characterized by use of dialect or primary speech of another language and lack of English fluency. To determine the effectiveness of an open, responsive environment in lessening the educational gap between advantaged and disadvantaged children, several projects were undertaken to extend and evaluate the work done in previous years. Through the use of a mobile instructional library, a home visitation program was continued which brought the New Nursery School teaching strategies and related educational materials directly into the homes of the pupils. A small scale project to study the feasibility of a Spanish tutorial program for prekindergarten children was begun. A method of evaluating young children's comprehension of key grammatical elements was used, evaluated and revised. Results are discussed in terms of a comparative analysis of several testing measures. More than half of this document consists of tables and supplemental information. (Author/AJ)
