The Learning English as a Second Language (ESL) with Los Cumbancheros project was developed through the collaborative efforts of several New York State Government offices, community school districts in the Bronx, and the private corporate sector. Its objective was to provide supplemental services to at-risk students of limited English proficiency to keep them in school. The project's vehicle of instruction was a bilingual chorus that rehearsed several times per week and performed regularly. Los Cumbancheros taught students music theory through ESL and Native Language Arts (NLA). Students gained knowledge of music theory and met both the project's ESL and NLA objectives. Attendance records indicated that students participated actively in the program. Additionally, parents expressed enthusiasm for the program and were appreciative of the concomitant parental activities; the Los Cumbancheros parental involvement objectives were also met. (GLR)
