Mind & EverydayHow it works
How mixed practice feels slower but scores higher on the test.
In 2007 Rohrer and Taylor had students practise volume formulas: one group in blocks, one solid shape at a time, the other group mixed. During practice the block group led 89 to 60 percent. On a test a week later it flipped: mixed 63 percent, blocked 20 percent. Mixing forces you to first identify which method fits.
Useful: Mix problem types within one practice session, even if it feels messier.
