A field experiment, attitude surveys, and a process evaluation were conducted in order to evaluate the third year of Carrascolendas, a kindergarten--second grade bilingual series carried nationwide on the Public Broadcasting Service. Test scores showed that material presented in Spanish had a significant impact on learning in history and culture. First graders showed marked improvement in English and Spanish language skills. Several content areas were affected: history, culture, English and Spanish language skills, and math. Second graders benefited least, showing significant gains only in the Spanish content area of history and culture and in English fluency. There was little impact upon the Spanish content areas of science, phoneme/grapheme relations, and language mixing. Attitudes of teachers, parents, and children toward the series were positive, and a growth of pride in Mexican culture and increased use of the Spanish language were noted. The process evaluation found improvement in the management of the project, although insufficient dissemination of information about the series to potential viewers was regarded as a salient shortcoming.
