1. Unquestionable laws - These are often straightforward and can be framed within a curriculum without much contention.
2. Open-ended topics - While these can invite discussion, they also may lead to tangential debates that can be difficult to manage in a classroom setting.
3. Problems or cases - Typically, these are relevant for practical learning and are often used in problem-based learning methodologies.
