In its fourth year, Project MASTER served 477 Spanish-speaking students in 5 elementary schools in the Bronx. The teaching strategy was holistic, integrating all aspects of the curriculum with English-language learning through science projects. The project developed curriculum materials, stressing attitudes toward and knowledge of science topics, and actively pursued capacity-building among bilingual teachers at project sites and in community projects. Objectives were achieved in English as a Second Language and mathematics. Assessment of objectives in science was not possible. Project strengths included a holistic, interdisciplinary, hands-on approach, an active engagement with community ventures, and the maintenance of an excellent relationship with school personnel. One recommendation for program improvement is the dedication of resources to capacity building for bilingual teachers, which will provide the necessary resources for incorporation of the project's approach into the regular school curriculum.
