Secrets of Interleaved Practice | How Learning Works

Описание: Can rearranging the order in which you solve problems accelerate your learning? You bet. This is a breakdown of the idea of interleaving (as opposed to blocked practice), with a couple of tips for using interleaving more effectively.

00:00 Introduction
00:22 Defining blocked practice
01:03 Defining interleaved practice
01:46 The logic behind blocked practice: collecting skills
02:30 Interleaved practice spaces out your practice (which offers one advantage)
03:37 Interleaved practice helps us distinguish things
04:11 Interleaved practice focuses on the right skill
05:02 Time for a test
06:10 Findings from a study on interleaving math homework
07:13 When introducing new topics, start off with blocked practice
07:36 Interleaved practice is not task-switching

The study I mentioned comparing blocked to interleaved math homework problems is below. The numbers I took were from a 30-day delayed test. Delayed tests are where you often see the largest gains for interleaved practice.
