Whenever someone is trying to learn a new language, there are difficulties because language is so difficult. The best way to approach learning a new language, I would think, is specific practice with real-world applications in the fundamentals of that language. Unfortunately, the public school system is fumbling to meet even the most basic needs, so the students are often thrown into a mainstream class and expected to come up to speed.
These students do have several things in their favor. Since they are already in the process of learning the new language, their consciousness is being brought to the structural level of that language. On the flip side, they are often unaware of the little nuances that make language so strange and difficult. If the students have reached the typical grade level for which they are meant, the struggles will be less pronounced simply because they have an understanding of the academic expectations.
On the other hand, there are students whose education may have been interrupted for any number of reasons. These students still have a lot in their favor, if the school system can adjust programs to meet their individual needs. One teacher would be unable to do everything that these students will need to be successful in their academic career. The most important thing for these students is a cohesive faculty with lots of support from every department.
