Dual language exposure and bilingualism are relatively common experiences for children. The present review set out to synthesize the existing research on cognitive development in bilingual children and to identify the gaps and the methodological concerns present in the existing research. A search of major data bases for research conducted with typically-developing, preschool-age dual language learners between 2000-2013 yielded 102 peer-reviewed articles. The existing evidence points to areas of cognitive development in bilingual children where findings are robust or inconclusive, and reveals variables that influence performance. The present review also identifies areas for future research and methodological limitations.

Yes, I believe that bilingual education is beneficial, because it gives children opportunities later on. The children learn not to be afraid of other cultures. They learn that they are capable of learning a new language. The skills can help them secure jobs as adults when they enter the working world.
Learning two languages can not be a negative thing. Almost all social interactions involve speaking to another person. By limiting the people you can speak with, you limit yourself to the people you can interact with. Breaking down communication barriers can lead to better relations between countries or even promote cultural equality.
Bilingual education is important because it allows you to communicate with others that you may be around a lot. It helps in jobs where you may be working with people that speak another language. It also helps in society where you may be friends with, or are around, people that speak another language.
In Europe, it is common for people to know and use three or even more languages. The same is true for many parts of the world. It is only in the United States that monolingualism gets defended. Speaking more than one language allows people to communicate better with each other. Understanding more than one language also helps a person understand and use his/her native language better. Militant monolingualism such as what gets practiced in the United States is a fundamentally selfish stance.
There is not enough nativism within the USA. Nativism, not racism. US road signs, most federal workers, and most legal documents are in English. Not ensuring the immigrant populous is fluent in English is a disservice for no other purpose than trying to be PC. English is the fastest growing language and is a lingua franca; English is more beneficial in the long run than anything else.
Bilingual education at some point make a language difficult to learn since natural environment of a language is much better option. Mostly teachers on the name of bilingual method become merely translators because of which language learning in schools have become only learning question and answers and obtaining marks. In most schools children never verify the definition of language.
