What information should be included in flashcards?

Flashcards should include key concepts, terms, or questions on one side, and their definitions, explanations, or answers on the reverse side. It is important to keep the information concise and focused to facilitate quick recall. Including examples or illustrations can enhance understanding, especially for complex topics. For instance, in a flashcard for the term 'photosynthesis,' write the definition on one side and a simple diagram of the process on the other. This method of active recall and spaced repetition can significantly improve retention and understanding of the material.
