Hi I am Justin Love. OK, a dry CV, if you have the right qulalificatiins/experience may get you a job, but if there is competition, your epistle may get filed away with other 'possibles'. Therefore, you should consider adding a presentation. What's special about how you teach? How do you motivate your students? What are your values and philosophy as a teacher?.
Write it up nicely, stick in a few choice quotes, a serving of science, stir in some levity, and a pinch or two of pathos. That will show you know how to communicate effectively in English. It also indicates that you have personality, which when it comes to teaching english to non native speakers is a perquisite.
Placements aare a gamble and administration will often look favourably on an applicant who is very positive, expressive and confident. They have nothing to lose, you may turn out to be a great asset to the school and at worst, will probably still do OK.
