What is spiral review?

Spiral review is short, regular practice that brings back skills learned earlier, mixed together, so they are not forgotten after the unit ends.

The three ideas behind it

  • Spacing: an IES practice guide recommends spacing learning over time, with a “Moderate” evidence rating[1].
  • Quizzing: the same guide recommends using quizzes to re-expose students to key content, with a “Strong” rating[1].
  • Interleaving: problems of different kinds are mixed so that no two in a row are the same, which makes students choose a strategy for each one[2].

Is spiral review good?

Research on spaced and mixed practice is encouraging. A review of study techniques rated practice testing and distributed practice highest[3]. A randomized classroom trial of interleaved math practice with 787 students met What Works Clearinghouse standards without reservations and found a statistically significant positive effect[4].

Results depend on how it is used: the review's authors note that the techniques help students who are motivated and able to use them[3], and the WWC notes that one study review may not reflect the full body of evidence[4].

Tips for using it at home or in class

  • Keep each day short: a few mixed items, not a full page.
  • Skip skills your student has clearly mastered.
  • Check answers the same day, so a mistake is not practised again.
  • Use a short weekly check to see what needs more time.

Questions

What does spiral review mean?

Short, regular practice that brings back skills learned earlier, mixed together. An IES practice guide recommends spacing learning over time and using quizzes to re-expose students to key content[1].

Is random review the same as spiral review?

Not quite. A good spiral brings each skill back on a plan, and mixes problem types on purpose so students must choose a strategy for each problem[2].

How long should it take each day?

Keep it short. Our own daily sets are designed for a few minutes a day.
