Multicenter Study Investigating Foreign Language Acquisition at School in Children, Adolescents, and Young Adults...

Evaluation of foreign language acquisition at school in cochlear implant patients.

Multicenter cohort study.

CI centers.

One hundred twenty-five CI users (10-18 yr) in the German-speaking part of Switzerland were enrolled. Demographic data were obtained by means of written questionnaires. German-speaking children with mainstream foreign language tuition (English and/or French) were enrolled for further testing. The control group of normal-hearing individuals was matched on age, class, and number of foreign language lessons attended.

Overall, 100 questionnaires were returned. The 12 CI users without foreign language learning attended special schools. CI users who attended foreign language classes had better German speech comprehension compared with those without foreign language tuition (89 versus 51%; p < 0.05). Thirty-one CI users of different grades were further tested. All (10/10) CI 6th graders attained the school objectives for both English reading and listening skills. French performance at 6th grade for reading was 3/7 and for listening only 1/7. There were 13 matched normal-hearing pairs for English and 10 for French. The total scores were on average 7% higher, with a statistical significance for English reading (p < 0.05).

Almost 90% of CI children in Switzerland learn foreign language(s) at school. All the tested patients reached the current school objectives for English reading. The success rate for French was lower, especially regarding listening tasks. The 13 matched pairs with normal-hearing did not score substantially better.
