Random Practice Schedule?
What if we took the blocks of practice on particular tasks and broke them down into smaller segments on each task? For example, baseball players could hit three different types of pitches in an alternating fashion, instead of doing all of one kind in a row. Two breakdown options are a repeating order (e.g., abc abc abc…) or an arbitrary order (e.g., acb cba bca…). In either, the net result will still be 15 practice hits of each of the three types of pitches, exactly the same as the net result in the blocked practice schedule. The only variable that changes is the order in which the pitches are practiced. This type of interspersed schedule is called a random practice schedule
(also known as an interleaved practice schedule).
In a random practice schedule, the performer must keep restarting different tasks. Because beginnings are always the hardest part, it will not feel as comfortable as practicing the same thing over and over again. But this challenge lies at the heart of why random practice schedules are more effective. When we come back to a task after an intervening task, our brain must reconstruct the action plan for what we are about to do. And it is at this moment of reconstruction that our brains are the most active. More mental activity leads to greater long-term learning. In the blocked schedule above, the baseball players must only construct the action plan for each type of pitch once, at the beginning of each block. In the random schedule, they must construct and later reconstruct an action plan fifteen times for each pitch. Although a blocked schedule may produce superior performance during practice, study after study has shown that a random practice schedule consistently produces superior retention following practice a day or more later (i.e., the amount actually learned). This phenomenon is called the contextual interference effect.
How to use a random schedule in the practice room
Rather than spending long uninterrupted periods of time woodshedding each excerpt or section of a piece, pick a few passages you would like to work on and alternate between them. If you want to spend a total of 30 minutes on a particular excerpt, practice in shorter segments, continually returning to this excerpt until you have achieved your 30-minute goal. Experiment with lengths of time. If you are practicing excerpts that are very short, you may be able to switch between them at a faster pace than would be required for longer sections.
You can use a small alarm clock to time specific intervals or switch after each repetition.
Practicing passages in different rhythmic variations is a great
way of introducing contextual interference on a smaller scale. But instead of doing all rhythmic variations on a single excerpt before moving onto the next, do one variation on excerpt A, one on excerpt B and then return to excerpt A for a second variation etc. Technique can also be interspersed into the random schedule, instead of doing all of it in one long block.
The permutations are endless and the exact division of time is not important. What is crucial is that you are keeping your brain engaged by varying the material. More engagement means you will be less bored, more goal-oriented (you have to be if you only have 3 minutes to accomplish something), and substantially more productive. Most importantly, when you return to the practice room the next day, you can start from where you left off.
This type of practice sticks.
