Learning the ins and outs of English grammar is not much fun for many English language students. Whether you are teaching ESL (English as a Second Language) students or native English speakers, showing students why and how the grammar point you are teaching is important in daily life will help them learn it. When students figure out the grammar structure for themselves, they are more likely to retain the information. (See Reference 1.)
Show students how the grammar structure is used in their everyday lives. This will help encourage them to learn the structure. Utilize relevant role play modeling an authentic conversation or a reading text that contains the grammar structure.
Ask students questions about the role play or reading selection using the grammar structure you want to teach. Listen to their responses to see if they are using the structure.
Teach the specific grammar concept. Ask students to identify when they think the structure is used and for any other information they notice about it from the role play or the reading. Students are discovering the rules for the structure themselves when you encourage them to think about how the grammar point is used in English.
Follow-up with a grammar exercise that utilizes the grammar point you've taught such as a fill-in the blank or creative writing exercise where students use the grammar point. Students could also pair up or form groups and model a role play where the grammar point is used throughout.
