Interleaved Practice: Mixing It Up

Interleaved practice involves mixing different subjects or types of problems within a single study session. Unlike blocked practice, where learners focus on one topic at a time, interleaving encourages the brain to constantly switch gears. Research suggests that this method improves problem-solving skills and enhances the ability to transfer learning to new contexts. By challenging the brain to differentiate between concepts, interleaving strengthens cognitive flexibility and deepens understanding. This technique can be particularly beneficial in subjects like mathematics and science, where varied problem types are common. Incorporating interleaved practice can lead to more robust learning and better retention over time.
