Thoughts on teaching grammar

I strongly believe that grammar rules should be memorised by students because they could know if they had made a mistake instantly on their own. However the grammar rules are not the only things that students should remember. They should also make a clear mind on why they use it, i.e. the meaning and the function. These two aspects are also important because the current students are more eager to understand the meaning rather than being used to the way of spoonfeed teaching. They do not like drills that much and may find them torturing. However, thanks to my primary school teachers, I had suffered from drilling and through endless copying, I realised the grammar rules(forms). Therefore, I think drills are useful in teaching grammar, but only under the circumstances to those students who are eager to learn English. Boosting my students' interests is actually a headache to me now. Therefore I would just give them some exercises and not prolonged drilling.
I personally prefer an inductive approach to grammar teaching as it can let students know the function of each grammar item. Also, the rules are boring to students. They may not be attentive enough to learn from me if I just introduced the rule and asked them recite. I think dialogues, and some conversations among students can motivate them to use the grammar, rather than just solely exercises given to students to finish. I definitely believe interesting examples could make them remember the grammar item.
