Important attributes of good spaced repetition memory prompts

This note collects ideas about how to encode knowledge into Spaced repetition memory system prompts, both to support memory of facts but also to foster richer understanding (Spaced repetition memory systems can be used to develop conceptual understanding).

See How to write good prompts (2020) for a published manuscript on this topic.

Basic attributes of prompt-writing:

• Spaced repetition memory prompts should be concise
• Spaced repetition memory prompts should usually focus on one atomic unit
• Spaced repetition memory prompts should encode ideas from multiple angles
  • Spaced repetition memory prompts should connect and relate ideas
• Spaced repetition memory prompts should unambiguously produce a specific answer
  • Prompts must make clear what “shape” of answer they expect
• Spaced repetition memory prompts should ensure reviewers must retrieve answers from memory
  • Avoid yes-no spaced repetition memory prompts
• Spaced repetition memory prompts should be written to discourage shallow “pattern matching”
• Beware set\/enumeration SRS prompts
• Cloze deletion prompts seem to produce less understanding than question-answer pairs in spaced repetition memory systems
• Expert response heuristic, after Issa Rice

“Covering” material:

• Avoid orphan spaced repetition memory prompts

Meta / mental models:

• A pattern language of prompt-writing
• Rule of thumb: write more spaced repetition prompts than seems natural
• Spaced repetition prompt design is about designing tasks for your future self
