The study investigated the effects of bilingual teaching on the development of children's literacy skills and attitudes towards language learning. In the bilingual classes 20% of the instruction was given in English. Pupils’ literacy skills in the bilingual classes were significantly better than in the monolingual classes.
When observing pupils who started first grade with either a poor or an excellent level of school readiness, there was no significant difference between bilingual and monolingual groups. In addition, the pupils in bilingual classes showed significantly more positive attitudes towards foreign-language learning than the pupils in monolingual classes.
