Bilingual Education 

What Does Research Say?

There is a compounding body of quantitative, qualitative, longitudinal and cross-sectional research that supports the efficacy and effectiveness of bilingualism and multilingualism.

 

In the section below, we have organized some of the most poignant pieces of research from the field into four categories: cognitive development, academic achievement, social-emotional development and racial justice. 

COGNITIVE DEVELOPMENT

 

​

 

 

"Bilingualism makes the brain stronger. It is brain exercise."

​

 

Ellen Bialystok, Cognitive Neuroscientist

ACADEMIC ACHIEVEMENT

​

 

"Study after study has reported that children in bilingual programs typically outperform their counterparts in all-English programs on tests of academic achievement in English."

​

Stephen Krashen, Linguist and Educational Researcher

University of Southern California

social emotional development

​

 

 

Children exposed to several languages are better at seeing through others’ eyes.
