This report presents the evaluation of the 1973-1974 Fall River Middle School Research and Development Center, a project funded by ESEA Title VII as a model demonstration bilingual program beginning in 1972-1973. The evaluation focused on the assessment of the degree of accomplishment of product objectives for each component of the program. The program had a total enrollment of 244 students--161 Portuguese dominant students and 83 English dominant students. The program served 119 fifth grade and 127 sixth grade students. Fifth grade English dominant students were selected for the program from the fourth grade student population who would normally be going into the fifth grade during the 1973-1974 school year. Fifth grade Portuguese dominant students were selected through consideration of two factors in addition to their language dominance--school age and neighborhood. The sixth grade students are last year's fifth grade bilingual students. The staff included the following personnel: project director, staff development specialist, English as a Second Language Coordinator, guidance counselor, parent-community coordinator, four curriculum specialists, 12 teachers, four teacher aides, and an audio-visual materials development assistant. The average class size for the 12 classes--four each at the three participating schools--was 20 students per class. (Author/JM)
