Claims need sources
Research claims are checked against the linked source, with its scope and limitations in mind. A framework, an author’s opinion and an experimental finding are different kinds of evidence. A source may support one part of a lesson without validating the whole teaching method.
Examples must be honest
Our teaching scenarios are fictional and labelled as such. They illustrate a decision, not an observed outcome or a promise. Famous success stories cannot establish a universal rule; resources, failed attempts and alternative explanations deserve attention.
Two languages, shared substance
English and Chinese lessons share objectives, the practical task and the basis for their knowledge check. Language is edited for clarity rather than translated word for word. When examples differ, they must preserve the point being taught.
Limits and corrections
AI can introduce factual or interpretive mistakes, and these materials may still contain errors. Check the original source when a claim matters to a consequential decision. For medical, legal or personal financial decisions, use suitable qualified support.
To flag an issue, record the lesson title, the passage and a supporting source, and share them with the project organiser through the channel where you found this site. This edition does not collect correction reports through a form.
Current release: Foundation edition, September 2026. No external human expert review or formal validation study is claimed.
