You should ask the school which level the learners will be (beginner, intermediate or advanced) and then tailor your lesson plan accordingly. The school will normally be happy to tell you, but keep in mind that sometimes part of the interview may be to identify the level! Ensure you know the age range of the students you’ll be teaching (adults, teenagers, or young learners) and keep that in mind when planning the lesson and activities. This shows the interviewer that you have the ability to teach the students at their school. Also find out how many students would be in a typical class at the school you’re being interviewed for and plan the lesson activities for that number (as well as a few more, and a few less).
Confirm with the interviewer how long the demo lesson should be and then plan for that time frame. But always make sure you include extra activities, just in case they’re needed to fill time.
Make sure that you’re absolutely clear on the grammar point (or points) you need to cover in the demo lesson - if you’re unsure, double-check with the interviewer beforehand. Don’t incorporate other grammar points if you’re not asked to; be sure to stay on task. It’s also good to try to include different activities that are tailored for different learning styles - visual, auditory and kinesthetic. This might mean including a mix of mediums, like a video, some cue cards and some writing exercises for example.
In your lesson plan, highlight any potential problems or challenges that you may encounter during the lesson (for example, explaining vocabulary, or a tricky grammar point) and outline how you would overcome these issues.
Finally, practice makes perfect. Ask a friend to record your lesson, or try a few trial runs on YouTube using your webcam. Watch the video afterwards for self-assessment. Be aware of the clarity of your voice, eye-contact, body language and mannerisms, and overall enthusiasm in your delivery. It’s best to iron out these wrinkles before you do the real thing in front of your potential future boss. Before you do the lesson live, be sure to check everything tech related.
During the Demo
Speak clearly and loudly enough to be heard. There’s nothing worse than having to repeat yourself over and over because the interviewer can’t hear you. It’s embarrassing, and obviously will affect the flow of the lesson. On the other hand, make sure you’re not speaking so loud that you’re deafening the interviewer!
Keep on track with your lesson plan as much as possible, but also have the flexibility to deviate if needed to ensure the lesson objectives are met.
After the Lesson is Over
Seek feedback. The interviewer may not give you any feedback after the lesson, so you may need to request feedback in an email after the interview process. In your email, it’s good to be clear about what type of feedback you want, and on which specific aspects of your demo lesson.
