Make It Stick: Why can't I remember moves when I go home after class??
Most people think that repeating information over and over is the best way to learn. In "massed practice," we repeat the same information/moves over and over again, until it feels familiar. Unfortunately, instead of creating long-term memory, when we do this, we are working with our short-term memory. As we loop through our short-term memory, the material begins to feel familiar. We gain confidence and feel good, as if we learned the movement really well. However, when we get home, we can't remember what we did in class (Brown et al. 83).
Just stuffing information into your brain does not help you learn. Think of cramming for an exam: you pass the exam, but is that information really available for later recall? For example, a tango festival, with twenty hours of lessons in a weekend, would be like cramming for an exam. How much of that information is still there a week later?
How to learn movement efficiently
Embrace the fact that significant learning is often, or even usually, somewhat difficult. You will experience setbacks. These are signs of effort, not of failure. Setbacks come with striving, and striving builds expertise. (Brown et al. 201)
Massed practice will not help you to learn tango. Instead, you need to space out your practice time. This helps your brain build the connections between the new information and what you already know, which cannot happen immediately. Also, the fact that you have to work hard to retrieve the information each time you practice, helps you learn more thoroughly (Brown et al. 65).
When people ask me how often they need to practice, or take classes, I tell them that it varies by person. If you want to improve, you need to review the information before you forget it; and then keep reviewing it. Personally, if I wait more than 48 hours to review something, I often can't find the information in my memory. So, for me, I need to practice at least every other day when I am trying to learn something new.
The learning from interleaved practice feels slower than learning from massed practice. Teachers and students sense the difference . . . and the compensating long-term advantage is not apparent to them. As a result, interleaving is unpopular and seldom used (Brown et al. 66-7)
Interleaving is studying at least two things, rather than just studying one. In an example from the book, a group of people who already were good at baseball were divided in two. One group was given massed practice of hitting several kinds of pitches, but one at a time. They felt good about how they were learning, and continued practicing for six weeks. The other group interleaved all the different kinds of pitches, never knowing what was coming up. They felt frustrated that they weren’t doing very well. At the end of six weeks of practice, they performed much better than the other group (Brown et al. 80-1).
Although I have used some of these techniques for years, some are new to me, or were things that I did not often do. I had felt pressure to make my lessons feel easier from my students, and had drifted towards too much repetition of one thing at a time. However, the changes I have made to class in the past three months have made a believer out of me: I am seeing results that I have not seen in 30 years of teaching! My students agree that class is more challenging and feels more frustrating, but they are learning faster.
If you interleave different skills or moves, you learn better than working on one thing, but you can improve on that with varied practice: mix it up! Do things in different orders! Do different exercises and drills!
The evidence favoring variable training has been supported by recent neuroimaging studies that suggest that different kinds of practice engage different parts of the brain. The learning of motor skills from varied practice, which is more cognitively challenging than massed practice, appears to be consolidated in an area of the brain associated with the more difficult process of learning higher-order motor skills. (Brown et al. 67)
My guess is that tango counts as a higher-order motor skill :-) When I teach private lessons, I often write three- to four- moves on the white board, and then have the student dance them in different orders. With the "cheat" of seeing the names of the moves, or pictures of them, the student works through different orders of movement. After that, I ask that they do so without looking at the board.
