My Final Research Paper Topic

For my final research paper topic i am planning on researching the social differences between children who study two languages versus children who only study in one. I myself have experienced both styles of education, as i have written in my memoir paper, for 4 years i went to a Yeshiva where i studied in Hebrew for the first half of the day and than English for the second half. After that I only studied in a typical American public school where everything i learned was in English. I want to research the positive and negative effects of both styles of language. I want to find out the social ramifications of both styles as well as the level of grades that are achieved in both situations.
