Stephen Krashen is one of the best known people who have a well thought-out and very detailed
He believes (and I think he's right) that students learning a second language, who will be expected to succeed academically in that language, follow a clear acquisition path. The timing may change somewhat from one person to the next, but the stages of acquisition of the new language are essentially the same.
He also believes that while children and teenagers are learning English, they should also be taught math, science, history, etc., in their primary language so that they do not fall far behind academically.
Read his work carefully. He's brilliant.
