An adult education class is preparing a discussion about online face classification. We want learners to examine the reasoning behind a label instead of seeking a preferred category. A topic reference I have saved for discussion is what is my face shape to introduce the subject. That inclusion would not imply that its results are accurate. Students could first write down which visible proportions they would expect a method to compare. Next, we could discuss what information a single photograph leaves uncertain or obscures. No participant would need to upload a personal image; a discussion of example descriptions would be sufficient. Each group could explain which evidence would change its initial interpretation. We could also compare two written descriptions of the same outline and ask whether their labels mean the same thing. This would make the assumptions available for discussion without requiring a supposedly correct personal result. Which discussion prompts would help learners examine assumptions without judging their own looks?
