I would like to see a paper on grammar instruction that conducts experiments with English language learners (students) and analyzes the results.
I am planning the instruction of "subjunctive mood" for junior high school students or high school students. I am searching for an effective introduction or essential grammatical elements, the way of explanation, and so on. Then, I check whether they can get a better understanding or not.
If there are some interesting research papers, please recommend me!!!
