The report evaluates a Swiss bilingual education program in the City of Sierre/Siders in which 19 Francophone children aged 5-6 years received half their instruction in French and half in German over a period of a year. Participants were evaluated for their German language skill development in November, February, and June. Results indicate that the children gained the targeted communication skills for daily classroom interaction, with limited production in German in most cases. The children's attitudes toward German and toward activities in German and with German speakers were generally positive. Basic instructional objectives were met and not compromised by bilingual instruction. Results were similar to those of comparable programs. Contains 29 references. The brief report is supplemented by substantial appended materials, including a program outline, the mandate for a bilingual education research group, a sociolinguistic survey of program participants, the three tests administered during the year, transcriptions of June language samples, the teachers' report, and evaluation data on each participating child.
