How might spaced repetition memory systems intervene when the student struggles with material?

The typical Spaced repetition memory system does two things: it shortens the interval until the next presentation, and it asks the student to retry the prompt in the same session.

Sana Labs reintroduces the article which originally presented the prompt’s material, either through suggestion (“maybe you’d like to reread this?”) or by simply presenting the article as a task in the review session (“you’re struggling with material from this article.”)

Because the Mnemonic medium ties the prompts tightly with a source text, it may have some extra opportunities here: it can potentially excerpt or return readers to a specific portion of a source article.

Other possibilities:

  • inject variations of the material to reinforce it more strongly
  • present material authored on a per-prompt basis intended for intervention
  • facilitate asking others for help

But, critically: Choice of intervention in a spaced repetition memory system must depend on reason for failure.
