How Languages Build Academic Performance:
- Children who learn a second language show either comparable or enhanced first-language literacy.
- Second-language learners often show enhanced spelling ability as well as superior reading comprehension when they are compared to their monolingual peers.
- Children receiving second-language instruction often show higher achievement in a range of subject areas, including mathematics, science and language arts.
- Learning a second language enhances second-language learners’ grammatical knowledge and awareness of speech sounds and sentence structures.
The above statements come from the Literature on the Impact of Second-Language Learning (2017).
