When evaluating a coursebook page, ask: does it actually match your learners’ level and interests, or does it need adapting? Common adaptations: replacing culturally irrelevant examples with local ones, adding a personalization step (having learners apply the language to their own lives, not just the textbook’s characters), or breaking a dense exercise into smaller staged steps for a weaker class. CELTA assessors value evidence that you can adapt materials thoughtfully, not just use them as printed.
