How might I improve my student’s grammar

Answer 1

I am not sure whether you are asking about the grammar of a native speaker (e.g. a child who is still learning) or a non-native speaker. What I do with non-native speakers who I teach is the following:

(1) I tell them to read more and to "copy" the grammar they encounter when reading.

(2) I systematically go through grammar books and practice difficult grammar topics, again, again, and again (repetition is essential for learning).

(3) I take a conversational approach to practice grammar. I let my students use grammar in conversations and take notes while they are speaking. I later debrief them and analyze their mistakes with them. And then we practice again. Very often, students just need to hear a grammatical structure over and over again.

Answer 2

Not understanding correct grammar usage is one topic for remedial help. However, not using correct grammar once learned is another situation entirely and can be remedied by having your student become use to the process of self editing, Many students rush to submit their work and do not take the time to edit. In editing, they would find grammatical mistakes, spelling mistakes, and could also find that their sentence structure was faulty.

Ii tell my students to edit not only those papers they turn in, but edit their essay answers on tests to be sure that they wrote what they meant to explain.
