Written Dr. John Archibald, Dr. Sylvie Roy and other researchers at from the Language Research Centre (LRC), of the University of Calgary, A Review of the Literature on Second Language Learning, 2nd ed. Published in 2006, this study examines 4 key areas:
- Effects of a second language on a person’s first language
- The role of content instruction in offering a second language
- Effects of second language learning on students with special needs
- Effects of learning and third language on students for whom English is a second language.
Some key findings of this research are:
- Exposure to a second language can enhance non-linguistic skills such as divergent thinking, attitudes towards others and math skills.
- Acquiring knowledge in a second language does not impede first language development.
- Significant time investment is required to acquire full fluency.
- Content-based language teaching (e.g. teaching math or science in a second language) can increase students’ ability to make connections between second language study and the outside world.
- Students with special needs can learn second languages.
- Acquiring a third language is a common occurrence around the world.
- It helps to learn a third language if you have a strong proficiency in a first language.
