My question

Currently my question is: What kinds of questions are my bilingual students asking and what skills do they have, that they can give to English Only students in order to greaten their (English only students') self-confidence and performance?

OR

What kinds of questions are my 2nd grade bilingual students asking and what skills do they have that they can share to greaten the self-confidence and performance of their English Only classmates?

The concern I have that motivated this question is: My English Only students are performing at a level that to me seems unsatisfactory. Because of their prior schooling in English, I would expect them to be reading, writing and speaking in a more academic fashion, yet the students who are mostly doing that are the students that are coming to me from bilingual classrooms.

One idea I have about data to answer this question is: Looking at the questions my bilingual students ask. Also possibly asking bilingual students to share out (either in an interview or in writing) how it is that they code switch and what strategies they use to help them when working in English.
